+
+Common Public License Version 1.0
+
+   THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS COMMON
+   PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF
+   THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
+   
+   1. DEFINITIONS 
+   
+   "Contribution" means:
+   
+     a) in the case of the initial Contributor, the initial code and
+     documentation distributed under this Agreement, and
+     
+     b) in the case of each subsequent Contributor:
+     
+     i) changes to the Program, and
+     
+     ii) additions to the Program;
+     
+     where such changes and/or additions to the Program originate from
+     and are distributed by that particular Contributor. A Contribution
+     'originates' from a Contributor if it was added to the Program by
+     such Contributor itself or anyone acting on such Contributor's
+     behalf. Contributions do not include additions to the Program
+     which: (i) are separate modules of software distributed in
+     conjunction with the Program under their own license agreement, and
+     (ii) are not derivative works of the Program.
+     
+   "Contributor" means any person or entity that distributes the Program.
+   
+   "Licensed Patents " mean patent claims licensable by a Contributor
+   which are necessarily infringed by the use or sale of its Contribution
+   alone or when combined with the Program.
+   
+   "Program" means the Contributions distributed in accordance with this
+   Agreement.
+   
+   "Recipient" means anyone who receives the Program under this
+   Agreement, including all Contributors.
+   
+   2. GRANT OF RIGHTS
+   
+     a) Subject to the terms of this Agreement, each Contributor hereby
+     grants Recipient a non-exclusive, worldwide, royalty-free copyright
+     license to reproduce, prepare derivative works of, publicly
+     display, publicly perform, distribute and sublicense the
+     Contribution of such Contributor, if any, and such derivative
+     works, in source code and object code form.
+     
+     b) Subject to the terms of this Agreement, each Contributor hereby
+     grants Recipient a non-exclusive, worldwide, royalty-free patent
+     license under Licensed Patents to make, use, sell, offer to sell,
+     import and otherwise transfer the Contribution of such Contributor,
+     if any, in source code and object code form. This patent license
+     shall apply to the combination of the Contribution and the Program
+     if, at the time the Contribution is added by the Contributor, such
+     addition of the Contribution causes such combination to be covered
+     by the Licensed Patents. The patent license shall not apply to any
+     other combinations which include the Contribution. No hardware per
+     se is licensed hereunder.
+     
+     c) Recipient understands that although each Contributor grants the
+     licenses to its Contributions set forth herein, no assurances are
+     provided by any Contributor that the Program does not infringe the
+     patent or other intellectual property rights of any other entity.
+     Each Contributor disclaims any liability to Recipient for claims
+     brought by any other entity based on infringement of intellectual
+     property rights or otherwise. As a condition to exercising the
+     rights and licenses granted hereunder, each Recipient hereby
+     assumes sole responsibility to secure any other intellectual
+     property rights needed, if any. For example, if a third party
+     patent license is required to allow Recipient to distribute the
+     Program, it is Recipient's responsibility to acquire that license
+     before distributing the Program.
+     
+     d) Each Contributor represents that to its knowledge it has
+     sufficient copyright rights in its Contribution, if any, to grant
+     the copyright license set forth in this Agreement.
+     
+   3. REQUIREMENTS
+   
+   A Contributor may choose to distribute the Program in object code form
+   under its own license agreement, provided that:
+   
+     a) it complies with the terms and conditions of this Agreement; and
+     
+     b) its license agreement:
+     
+     i) effectively disclaims on behalf of all Contributors all
+     warranties and conditions, express and implied, including
+     warranties or conditions of title and non-infringement, and implied
+     warranties or conditions of merchantability and fitness for a
+     particular purpose;
+     
+     ii) effectively excludes on behalf of all Contributors all
+     liability for damages, including direct, indirect, special,
+     incidental and consequential damages, such as lost profits;
+     
+     iii) states that any provisions which differ from this Agreement
+     are offered by that Contributor alone and not by any other party;
+     and
+     
+     iv) states that source code for the Program is available from such
+     Contributor, and informs licensees how to obtain it in a reasonable
+     manner on or through a medium customarily used for software
+     exchange.
+     
+   When the Program is made available in source code form:
+   
+     a) it must be made available under this Agreement; and
+     
+     b) a copy of this Agreement must be included with each copy of the
+     Program.
+     
+   Contributors may not remove or alter any copyright notices contained
+   within the Program.
+   
+   Each Contributor must identify itself as the originator of its
+   Contribution, if any, in a manner that reasonably allows subsequent
+   Recipients to identify the originator of the Contribution.
+   
+   4. COMMERCIAL DISTRIBUTION
+   
+   Commercial distributors of software may accept certain
+   responsibilities with respect to end users, business partners and the
+   like. While this license is intended to facilitate the commercial use
+   of the Program, the Contributor who includes the Program in a
+   commercial product offering should do so in a manner which does not
+   create potential liability for other Contributors. Therefore, if a
+   Contributor includes the Program in a commercial product offering,
+   such Contributor ("Commercial Contributor") hereby agrees to defend
+   and indemnify every other Contributor ("Indemnified Contributor")
+   against any losses, damages and costs (collectively "Losses") arising
+   from claims, lawsuits and other legal actions brought by a third party
+   against the Indemnified Contributor to the extent caused by the acts
+   or omissions of such Commercial Contributor in connection with its
+   distribution of the Program in a commercial product offering. The
+   obligations in this section do not apply to any claims or Losses
+   relating to any actual or alleged intellectual property infringement.
+   In order to qualify, an Indemnified Contributor must: a) promptly
+   notify the Commercial Contributor in writing of such claim, and b)
+   allow the Commercial Contributor to control, and cooperate with the
+   Commercial Contributor in, the defense and any related settlement
+   negotiations. The Indemnified Contributor may participate in any such
+   claim at its own expense.
+   
+   For example, a Contributor might include the Program in a commercial
+   product offering, Product X. That Contributor is then a Commercial
+   Contributor. If that Commercial Contributor then makes performance
+   claims, or offers warranties related to Product X, those performance
+   claims and warranties are such Commercial Contributor's responsibility
+   alone. Under this section, the Commercial Contributor would have to
+   defend claims against the other Contributors related to those
+   performance claims and warranties, and if a court requires any other
+   Contributor to pay any damages as a result, the Commercial Contributor
+   must pay those damages.
+   
+   5. NO WARRANTY
+   
+   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
+   PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
+   KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY
+   WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY
+   OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
+   responsible for determining the appropriateness of using and
+   distributing the Program and assumes all risks associated with its
+   exercise of rights under this Agreement, including but not limited to
+   the risks and costs of program errors, compliance with applicable
+   laws, damage to or loss of data, programs or equipment, and
+   unavailability or interruption of operations.
+   
+   6. DISCLAIMER OF LIABILITY 
+   
+   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
+   ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
+   INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
+   WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
+   LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
+   NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
+   DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
+   HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+   
+   7. GENERAL
+   
+   If any provision of this Agreement is invalid or unenforceable under
+   applicable law, it shall not affect the validity or enforceability of
+   the remainder of the terms of this Agreement, and without further
+   action by the parties hereto, such provision shall be reformed to the
+   minimum extent necessary to make such provision valid and enforceable.
+   
+   If Recipient institutes patent litigation against a Contributor with
+   respect to a patent applicable to software (including a cross-claim or
+   counterclaim in a lawsuit), then any patent licenses granted by that
+   Contributor to such Recipient under this Agreement shall terminate as
+   of the date such litigation is filed. In addition, if Recipient
+   institutes patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Program
+   itself (excluding combinations of the Program with other software or
+   hardware) infringes such Recipient's patent(s), then such Recipient's
+   rights granted under Section 2(b) shall terminate as of the date such
+   litigation is filed.
+   
+   All Recipient's rights under this Agreement shall terminate if it
+   fails to comply with any of the material terms or conditions of this
+   Agreement and does not cure such failure in a reasonable period of
+   time after becoming aware of such noncompliance. If all Recipient's
+   rights under this Agreement terminate, Recipient agrees to cease use
+   and distribution of the Program as soon as reasonably practicable.
+   However, Recipient's obligations under this Agreement and any licenses
+   granted by Recipient relating to the Program shall continue and
+   survive.
+   
+   Everyone is permitted to copy and distribute copies of this Agreement,
+   but in order to avoid inconsistency the Agreement is copyrighted and
+   may only be modified in the following manner. The Agreement Steward
+   reserves the right to publish new versions (including revisions) of
+   this Agreement from time to time. No one other than the Agreement
+   Steward has the right to modify this Agreement. IBM is the initial
+   Agreement Steward. IBM may assign the responsibility to serve as the
+   Agreement Steward to a suitable separate entity. Each new version of
+   the Agreement will be given a distinguishing version number. The
+   Program (including Contributions) may always be distributed subject to
+   the version of the Agreement under which it was received. In addition,
+   after a new version of the Agreement is published, Contributor may
+   elect to distribute the Program (including its Contributions) under
+   the new version. Except as expressly stated in Sections 2(a) and 2(b)
+   above, Recipient receives no rights or licenses to the intellectual
+   property of any Contributor under this Agreement, whether expressly,
+   by implication, estoppel or otherwise. All rights in the Program not
+   expressly granted under this Agreement are reserved.
+   
+   This Agreement is governed by the laws of the State of New York and
+   the intellectual property laws of the United States of America. No
+   party to this Agreement will bring a legal action under this Agreement
+   more than one year after the cause of action arose. Each party waives
+   its rights to a jury trial in any resulting litigation.

+2000-04-01 ast message catalog plan
+
+(1) error_info.dictionary should be error_info.catalog
+    to match xopen and the internal naming in our implementation
+    and also to more closely match the webster definition
+    (catalog == enumerated list)
+
+    DONE
+
+(2) nmake by default will
+	CATALOG = $(ID:N=+([A-Za-z0-9_]):?$(PWD:N=*/lib/*:Y,lib,,)$(ID)?$(PWD:B)?)
+	ERROR_CATALOG == "$(CATALOG)"
+    e.g., commands in src/cmd/std will use the "std" catalog; all of the
+    commands in src/lib/libcmd will use the "libcmd" catalog
+
+    nmake will add "[--catalog?$(CATALOG)]" to USAGE_LICENSE
+    optget() will set error_info.catalog if not defined on the first call
+    commands that don't emit messages before optget() need not change
+    otherwise the command should
+
+	error_info.id = "foo";
+	error_info.catalog = ERROR_CATALOG;
+
+    undefined references to { USAGE_LICENSE ERROR_CATALOG } are hard
+    compile time errors
+
+    DONE
+
+(3) add catalog argument to libcmd <cmd.h> cmdinit(argv, context, catalog)
+
+    DONE
+
+(4) msgcat global target build msgs/*.mso and $(CATALOG).msg
+    each Makefile will generate one catalog $(CATALOG).msg where
+
+    the *.msg files are weird -- we need to build them viewed over an
+    architecture specific tree, even though they will be eventually used
+    as architecture independent source
+
+    $(CATALOG).msg will be the "C" locale
+
+    debug will be a debugging locale that will translate each message to
+	(CATALOG-NAME:MESSAGE-INDEX)\n
+    this will make it easy to locate text that escaped translation (in what
+    should be translated output); it will also be a way for us to do
+    regression tests in the face of typo fixes -- presumably typos can be
+    fixed without changing the message index
+
+    see msgadmin(1)
+
+    DONE
+
+(5) once all this is working I'll do catopen(3) and msggen(1)
+
+    DONE
+
+(6) the makerules "all" action will
+	catgen $(CATALOG).cat
+	catgen $(CATALOG)-*.cat
+    and the makerules "install" action will copy the catgen output to
+	$(LOCALEDIR)/$(LOCALE)/LC_MESSAGES/$(CATALOG)*
+    where
+	LOCALEDIR = $(INSTALLROOT)/lib/locale
+
+    NOTE: still under consideration

+[+NAME?msgcc - C language message catalog compiler]
+[+DESCRIPTION?\bmsgcc\b is a C language message catalog compiler. It accepts
+	\bcc\b(1) style options and arguments. A \bmsgcpp\b(1) \b.mso\b file
+	is generated for each input \b.c\b file. If the \b-c\b option is not
+	specified then a \bgencat\b(1) format \b.msg\b file is generated from
+	the input \b.mso\b and \b.msg\b files. If \b-c\b is not specified then
+	a \b.msg\b suffix is appended to the \b-o\b \afile\a if it doesn\'t
+	already have a suffix. The default output is \ba.out.msg\b if \b-c\b
+	and \b-o\b are not specified.]
+[+?If \b-M-new\b is not specified then messages are merged with those in the
+	pre-existing \b-o\b file.]
+[M?Set a \bmsgcc\b specific \aoption\a. \aoption\a may be:]:[-option]{
+	[+mkmsgs?The \b-o\b file is assumed to be in \bmkmsgs\b(1) format.]
+	[+new?Create a new \b-o\b file.]
+	[+preserve?Messages in the \b-o\b file that are not in new
+		\b.msg\b file arguments are preserved. The default is to
+		either reuse the message numbers with new message text that
+		is similar to the old or to delete the message text, leaving
+		an unused message number.]
+	[+set=\anumber\a?Set the message set number to \anumber\a. The default
+		is \b1\b.]
+	[+similar=\anumber\a?The message text similarity measure thresshold.
+		The similarity measure between \aold\a and \anew\a message
+		text is 100*(2*gzip(\aold\a+\anew\a)/(gzip(\aold\a)+gzip(\anew\a))-1),
+		where gzip(\ax\a) is the size of text \ax\a when compressed by
+		\bgzip\b(1). The default threshhold is '$__similar__$'. A
+		threshhold of \b0\b turns off message replacement, but unused
+		old messages are still deleted. Use \b-M-preserve\b to preserve
+		all old messages.]
+	[+verbose?Trace similar message replacements on the standard error.]

+"	It accepts \bcpp\b(1) style options and arguments. \bmsgcpp\b"
+"	preprocesses an input C source file and emits keyed lines to the"
+"	output, usually for further processing by \bmsgcc\b(1). \bmsgcc\b"
+"	output is in the \bgencat\b(1) syntax. Candidate message text is"
+"	determined by arguments to the \bast\b \b<error.h>\b and"
+"	\b<option.h>\b functions. The \bmsgcpp\b keyed output lines are:]{"
+"	[+cmd \acommand\a?\acommand\a is a candidate for \b--??keys\b"
+"		option string generation. Triggered by"
+"		\bb_\b\acommand\a\b(int argc,\b in the input.]"

+"		should be entered into the catalog.]"
+"	}"
+"[+?The input source file is preprocessed with the \bpp:allpossible\b"

+"	be compiled error-free with a real compiler before running \bmsgcpp\b."

+# - More locales should be tested here (via ON_KSH_TEST_LOCALES below).
+#   Locales like "ru_RU.KOI8-R","de_DE.UTF-8", "is_IS.ISO8859-1", 
+#   "is_IS.UTF-8" and "nl_BE.ISO8859-15" are on our wishlist - but
+#   that is getting little bit more compliciated because these locales use
+#   ',' as decimal delimter. The best solution may be to wait for ksh93
+#   being integrated into OS/Net and then change the test sequence to
+#   use ksh93's associate/compound variables (this may require a flag
+#   day... ;-( ).
+#   The current list was mainly composed to cover various encodings and
+#   all important markets based on suggestions by Sun's i18n team.

+# - Due to the timing sensitivity of some of the tests, these tests should 
+#   be run on a quiet system with no other activity.

+     a) in the case of the initial Contributor, the initial code and
+     documentation distributed under this Agreement, and
+     
+     b) in the case of each subsequent Contributor:
+     
+     i) changes to the Program, and
+     
+     ii) additions to the Program;
+     
+     where such changes and/or additions to the Program originate from
+     and are distributed by that particular Contributor. A Contribution
+     'originates' from a Contributor if it was added to the Program by
+     such Contributor itself or anyone acting on such Contributor's
+     behalf. Contributions do not include additions to the Program
+     which: (i) are separate modules of software distributed in
+     conjunction with the Program under their own license agreement, and
+     (ii) are not derivative works of the Program.
+     
+   "Contributor" means any person or entity that distributes the Program.
+   
+   "Licensed Patents " mean patent claims licensable by a Contributor
+   which are necessarily infringed by the use or sale of its Contribution
+   alone or when combined with the Program.
+   
+   "Program" means the Contributions distributed in accordance with this
+   Agreement.
+   
+   "Recipient" means anyone who receives the Program under this
+   Agreement, including all Contributors.
+   
+   2. GRANT OF RIGHTS
+   
+     a) Subject to the terms of this Agreement, each Contributor hereby
+     grants Recipient a non-exclusive, worldwide, royalty-free copyright
+     license to reproduce, prepare derivative works of, publicly
+     display, publicly perform, distribute and sublicense the
+     Contribution of such Contributor, if any, and such derivative
+     works, in source code and object code form.
+     
+     b) Subject to the terms of this Agreement, each Contributor hereby
+     grants Recipient a non-exclusive, worldwide, royalty-free patent
+     license under Licensed Patents to make, use, sell, offer to sell,
+     import and otherwise transfer the Contribution of such Contributor,
+     if any, in source code and object code form. This patent license
+     shall apply to the combination of the Contribution and the Program
+     if, at the time the Contribution is added by the Contributor, such
+     addition of the Contribution causes such combination to be covered
+     by the Licensed Patents. The patent license shall not apply to any
+     other combinations which include the Contribution. No hardware per
+     se is licensed hereunder.
+     
+     c) Recipient understands that although each Contributor grants the
+     licenses to its Contributions set forth herein, no assurances are
+     provided by any Contributor that the Program does not infringe the
+     patent or other intellectual property rights of any other entity.
+     Each Contributor disclaims any liability to Recipient for claims
+     brought by any other entity based on infringement of intellectual
+     property rights or otherwise. As a condition to exercising the
+     rights and licenses granted hereunder, each Recipient hereby
+     assumes sole responsibility to secure any other intellectual
+     property rights needed, if any. For example, if a third party
+     patent license is required to allow Recipient to distribute the
+     Program, it is Recipient's responsibility to acquire that license
+     before distributing the Program.
+     
+     d) Each Contributor represents that to its knowledge it has
+     sufficient copyright rights in its Contribution, if any, to grant
+     the copyright license set forth in this Agreement.
+     
+   3. REQUIREMENTS
+   
+   A Contributor may choose to distribute the Program in object code form
+   under its own license agreement, provided that:
+   
+     a) it complies with the terms and conditions of this Agreement; and
+     
+     b) its license agreement:
+     
+     i) effectively disclaims on behalf of all Contributors all
+     warranties and conditions, express and implied, including
+     warranties or conditions of title and non-infringement, and implied
+     warranties or conditions of merchantability and fitness for a
+     particular purpose;
+     
+     ii) effectively excludes on behalf of all Contributors all
+     liability for damages, including direct, indirect, special,
+     incidental and consequential damages, such as lost profits;
+     
+     iii) states that any provisions which differ from this Agreement
+     are offered by that Contributor alone and not by any other party;
+     and
+     
+     iv) states that source code for the Program is available from such
+     Contributor, and informs licensees how to obtain it in a reasonable
+     manner on or through a medium customarily used for software
+     exchange.
+     
+   When the Program is made available in source code form:
+   
+     a) it must be made available under this Agreement; and
+     
+     b) a copy of this Agreement must be included with each copy of the
+     Program.
+     
+   Contributors may not remove or alter any copyright notices contained
+   within the Program.
+   
+   Each Contributor must identify itself as the originator of its
+   Contribution, if any, in a manner that reasonably allows subsequent
+   Recipients to identify the originator of the Contribution.
+   
+   4. COMMERCIAL DISTRIBUTION
+   
+   Commercial distributors of software may accept certain
+   responsibilities with respect to end users, business partners and the
+   like. While this license is intended to facilitate the commercial use
+   of the Program, the Contributor who includes the Program in a
+   commercial product offering should do so in a manner which does not
+   create potential liability for other Contributors. Therefore, if a
+   Contributor includes the Program in a commercial product offering,
+   such Contributor ("Commercial Contributor") hereby agrees to defend
+   and indemnify every other Contributor ("Indemnified Contributor")
+   against any losses, damages and costs (collectively "Losses") arising
+   from claims, lawsuits and other legal actions brought by a third party
+   against the Indemnified Contributor to the extent caused by the acts
+   or omissions of such Commercial Contributor in connection with its
+   distribution of the Program in a commercial product offering. The
+   obligations in this section do not apply to any claims or Losses
+   relating to any actual or alleged intellectual property infringement.
+   In order to qualify, an Indemnified Contributor must: a) promptly
+   notify the Commercial Contributor in writing of such claim, and b)
+   allow the Commercial Contributor to control, and cooperate with the
+   Commercial Contributor in, the defense and any related settlement
+   negotiations. The Indemnified Contributor may participate in any such
+   claim at its own expense.
+   
+   For example, a Contributor might include the Program in a commercial
+   product offering, Product X. That Contributor is then a Commercial
+   Contributor. If that Commercial Contributor then makes performance
+   claims, or offers warranties related to Product X, those performance
+   claims and warranties are such Commercial Contributor's responsibility
+   alone. Under this section, the Commercial Contributor would have to
+   defend claims against the other Contributors related to those
+   performance claims and warranties, and if a court requires any other
+   Contributor to pay any damages as a result, the Commercial Contributor
+   must pay those damages.
+   
+   5. NO WARRANTY
+   
+   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
+   PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
+   KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY
+   WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY
+   OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
+   responsible for determining the appropriateness of using and
+   distributing the Program and assumes all risks associated with its
+   exercise of rights under this Agreement, including but not limited to
+   the risks and costs of program errors, compliance with applicable
+   laws, damage to or loss of data, programs or equipment, and
+   unavailability or interruption of operations.
+   
+   6. DISCLAIMER OF LIABILITY 
+   
+   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
+   ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
+   INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
+   WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
+   LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
+   NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
+   DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
+   HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+   
+   7. GENERAL
+   
+   If any provision of this Agreement is invalid or unenforceable under
+   applicable law, it shall not affect the validity or enforceability of
+   the remainder of the terms of this Agreement, and without further
+   action by the parties hereto, such provision shall be reformed to the
+   minimum extent necessary to make such provision valid and enforceable.
+   
+   If Recipient institutes patent litigation against a Contributor with
+   respect to a patent applicable to software (including a cross-claim or
+   counterclaim in a lawsuit), then any patent licenses granted by that
+   Contributor to such Recipient under this Agreement shall terminate as
+   of the date such litigation is filed. In addition, if Recipient
+   institutes patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Program
+   itself (excluding combinations of the Program with other software or
+   hardware) infringes such Recipient's patent(s), then such Recipient's
+   rights granted under Section 2(b) shall terminate as of the date such
+   litigation is filed.
+   
+   All Recipient's rights under this Agreement shall terminate if it
+   fails to comply with any of the material terms or conditions of this
+   Agreement and does not cure such failure in a reasonable period of
+   time after becoming aware of such noncompliance. If all Recipient's
+   rights under this Agreement terminate, Recipient agrees to cease use
+   and distribution of the Program as soon as reasonably practicable.
+   However, Recipient's obligations under this Agreement and any licenses
+   granted by Recipient relating to the Program shall continue and
+   survive.
+   
+   Everyone is permitted to copy and distribute copies of this Agreement,
+   but in order to avoid inconsistency the Agreement is copyrighted and
+   may only be modified in the following manner. The Agreement Steward
+   reserves the right to publish new versions (including revisions) of
+   this Agreement from time to time. No one other than the Agreement
+   Steward has the right to modify this Agreement. IBM is the initial
+   Agreement Steward. IBM may assign the responsibility to serve as the
+   Agreement Steward to a suitable separate entity. Each new version of
+   the Agreement will be given a distinguishing version number. The
+   Program (including Contributions) may always be distributed subject to
+   the version of the Agreement under which it was received. In addition,
+   after a new version of the Agreement is published, Contributor may
+   elect to distribute the Program (including its Contributions) under
+   the new version. Except as expressly stated in Sections 2(a) and 2(b)
+   above, Recipient receives no rights or licenses to the intellectual
+   property of any Contributor under this Agreement, whether expressly,
+   by implication, estoppel or otherwise. All rights in the Program not
+   expressly granted under this Agreement are reserved.
+   
+   This Agreement is governed by the laws of the State of New York and
+   the intellectual property laws of the United States of America. No
+   party to this Agreement will bring a legal action under this Agreement
+   more than one year after the cause of action arose. Each party waives
+   its rights to a jury trial in any resulting litigation.

+The advanced software technology department has been collecting useful C
+routines in a single library called libast.  libast is used by nmake, the
+nmake cpp (which is mainly based on another library (libpp)), CIA
+(C information abstractor from Robin Chen), and a collection of other
+/bin and /usr/bin commands that benefit from concentrating functionality
+in libast.
+
+More detail is available in the man pages.  libast contains:
+
+  (1)	routines to support a generic environment for
+	a variety of UNIX operating system variants
+
+  (2)	routines that update standard libc routines
+
+  (3)	routines shared between several commands
+
+If you already have nmake 2.0 or newer installed then use
+`nmake install' from this directory, otherwise use
+ship/shipin from the root of the distribution directory tree.
+
+Some of the routines not found in section 3:
+
+hash:			generic, scoped hash table support
+
+	hashalloc	create a hash table or push new scope
+	hashdump	debug dump of one or all hash tables
+	hashfree	free a hashalloc()'d table
+	hashlook	low level name lookup
+	hashscan	entry generator for scoped table scan
+	hashsize	explicitly change table size (usually automatic)
+	hashwalk	apply function to each table entry
+	memhash		return hash code for n-char chunk of memory
+	strhash		return hash code for null terminated string
+
+include/ast:		libast support headers
+
+	align.h		compile time type alignmnent support
+	dirent.h	POSIX directory(3) interface definitions
+	error.h		error() interface definitions
+	ftw.h		ftwalk() interface definitions
+	hash.h		hash*() interface definitions
+	ls.h		strls() interface definitions
+	re.h		re*() interface definitions
+	tar.h		POSIX ustar format interface definitions
+	tm.h		tm*() interface definitions
+
+misc:
+
+	cmdargs		apply a sequence of cmd line option parsers
+	cmdopen		like popen() but stdin and stdout are specified
+	cvtatoe		convert ASCII to EBCDIC
+	cvtetoa		convert EBCDIC to ASCII
+	error		output generic error and trace messages
+	ftwalk		an ftw(3) that works -- used in new tw(1)
+	getcwd		uses $PWD if ok, doesn't use /bin/pwd
+	getshell	return full path of shell for cmdopen()
+	ooptget		optget() for obsolete ar(1) and tar(1) options
+	optget		YA getopt(3) but no argc or error message output
+	pathaccess	find file with specific acces on list of dirs
+	pathcanon	canonicalize path name in place
+	pathcmd		return full path name of executable using $PATH
+	pathroot	determine `related root' directory for command
+	perror		uses strerror()
+	readargs	append each line of file to argv[0]
+
+re:			egrep(1) and ed(1) style re's from V9
+			(not the good awk(1) algorithm)
+
+	recomp		compile re pattern
+	reerror		report re*() errors
+	reexec		match string using compiled re
+	resub		ed(1) style substitute using last reexec()
+
+string:
+
+	chresc		return next char in string converting \ sequences
+	ctoi		convert char constant string to int
+	strcopy		like strcpy(3) but returns end of destination
+	strdup		malloc(3) and strcpy(3) smashed together
+	strerror	return error message string given errno
+	stresc		convert \ sequences in string in place
+	streval		evaluate C expression in string
+	strls		ls -l format support
+	strmatch	Korn shell file pattern match
+	strmode		return ls -l style output given st.st_mode
+	strsignal	return signal id string given SIG* number
+	strtape		convert generic tape unit to /dev/* file
+	token		generate space separated tokens in string
+
+tm:			time conversion support
+
+	tmdate		convert date string to time_t
+	tmform		format time_t to date string
+	tmmake		return current time_t
+	tmtime		convert struct tm to time_t

+.SH NAME
+libast \- introduction to the ast library
+.SH DESCRIPTION
+This section describes the
+.I AST
+(AT&T Software Technology) library functions of the
+.B libast
+library.
+.B libast
+serves three major purposes.
+First, it presents (a subset of) POSIX/ANSI standard headers and interfaces on
+non-compliant systems.
+Second, it provides a portable base of routines that implement concepts
+common to all UNIX system variants.
+Finally, it is a forum for
+modern implementations of features present (or lacking)
+in the standard C libraries.
+Features better provided by separate libraries are omitted from
+.BR libast .
+For example, most terminal driver interface issues are left for
+special purpose libraries such as
+.IR curses (3).
+.PP
+The
+.B libast
+related header files are installed in the directories
+.LR include/ast .
+Routines that do not advertize their own headers are prototyped in
+.LR <ast.h> .
+.L <ast.h>
+is ANSI, K&R and C++ compatible and includes or defines the equivalent of
+.LR <limits.h> ,
+.LR <stddef.h> ,
+.LR <stdlib.h> ,
+.LR <sys/types.h> ,
+.L <string.h>
+and
+.LR <unistd.h> .
+Other libraries that depend on 
+.B libast
+may also have headers installed in the
+.L include/ast
+directories.
+.SH FILES

+
+char*          astconf(const char* \fIname\fP, const char* \fIpath\fP, const char* \fIvalue\fP);

+int            astquery(int \fIfd\fP, const char* \fIformat\fP , ...);
+.EE
+.SH DESCRIPTION
+.L astconf
+is a string interface to the
+.IR confstr (2),
+.IR pathconf (2),
+and
+.IR sysconf (2)
+calls.
+If
+.I value
+is
+.L 0
+then the configuration parameter value for
+.I name
+is returned.
+Some
+.I name
+configuration parameters may consult the
+.I path
+argument.
+In this case if
+.I path
+is
+.L 0
+then
+\f5"/"\fP
+is used.
+Otherwise if 
+.I path
+is not
+.L 0
+then it must exist.
+The string return value for
+.I name
+remains unchanged until the next
+.L astconf
+call on
+.IR name .
+If
+.I value
+is
+.L 0
+then a valid string is always returned;
+\f5""\fP
+is returned if
+.I name
+has no configuration value.
+This simplifies the programming interface:
+.EX
+if (!strcmp(astconf("PATH_RESOLVE", NiL, NiL), "logical"))
+	/* the logical way ... */
+.EE
+If
+.I value
+is not
+.L 0
+then the configuration parameter value for
+.I name
+is set to
+.IR value .
+.L 0
+is returned if the value cannot be set.
+The paradigm is:
+.EX
+universe = astconf("UNIVERSE", 0, "att");
+\|.\|.\|.
+astconf("UNIVERSE", 0, universe);
+.EE
+The settable configuration names are:
+.TP
+.L FS_3D
+.L 1
+if
+.IR 3d (1)
+viewpathing is enabled,
+.L 0
+otherwise.
+This is an alternative to the
+.IR fs3d (3)
+interface.
+.TP
+.L PATH_RESOLVE
+.L logical
+if symbolic links are followed during file tree traversal,
+.L physical
+if symbolic links are not followed during file tree traversal,
+and
+.L metaphysical
+if symbolic links are followed at the top level during file tree traversal.
+These correspond to the generic
+.LR \-L ,
+.LR \-P ,
+and
+.L \-H
+command options.
+.TP
+.L UNIVERSE
+.L ucb
+for 
+.I Berkeley
+style and
+.L att
+otherwise.
+This configuration parameter controls the
+.I universe
+setting on machines that support it (e.g., Pyramid).
+.L UNIVERSE
+also controls the behavior of some commands like
+.IR cat (1)
+and
+.IR echo (1).
+.PP
+User defined
+.I name
+values may also be set and queried, but these should probably have
+some form of vendor prefix to avoid being stomped by future standards.
+.PP
+.L astconfdisc
+registers a discipline function
+.EX
+int (*notify)(const char* \fIname\fP, const char* \fIpath\fP, const char* \fIvalue\fP);
+.EE
+that is called just before the configuration parameter
+.I name
+is set to
+.I value
+relative to
+.IR path .
+If
+.I notify
+returns 
+.L 0
+then the configuration parameter value is not changed.
+.PP
+.L astconflist
+lists the current configuration names and values of
+.IR stream .
+If
+.I path
+is
+.L 0
+then \f5"/"\fP is used where appropriate.
+If
+.I flags
+is
+.L 0
+or
+.L R_OK|W_OK
+then all configuration parameters are listed.
+.L R_OK
+lists the readonly configuration parameters and 
+.L W_OK
+lists the settable configuration parameters.
+.L X_OK
+lists the settable configuration parameters in a form that can be
+snarfed for input to the
+.IR getconf (1)
+command.
+.PP
+.L astcopy
+efficiently copies up to
+.I n
+bytes from the file descriptor
+.I rfd
+to the file descriptor
+.IR wfd .
+The actual number of bytes copied is returned; \-1 is returned on error.
+If
+.I n
+is  0 then an optimal number of bytes (with respect to both
+.I rfd
+and
+.IR wfd )
+is copied.
+.PP
+If possible
+.IR mmap (2)
+is used to do the transfer.
+Some implementations may bypass user buffer copies usually required by the
+.IR read (2)- write (2)
+paradigm.
+.PP
+.L astquery
+outputs an
+.IR sfprintf (3)
+prompt specified by
+.I "format, .\|.\|."
+to the controlling terminal and reads a response from the controlling terminal.
+Offirmative response returns
+.LR 0 ,
+.L EOF
+or quit response returns
+.LR \-1 ,
+otherwise
+.L 1
+is returned.
+If
+.I quit
+is greater than
+.L 0
+then
+.I exit(quit)
+is called on a quit response.
+The responses will eventually be locale specific.
+.PP
+.L astwinsize
+returns the number of rows in
+.I *rows
+and the number of columns
+.I *col
+for the terminal file descriptor
+.IR fd .
+If the number of rows or columns cannot be determined or if
+.I fd
+is not a terminal then
+.I *rows
+and
+.I *cols
+are set to
+.LR 0 .
+If
+.I ioctl (2)
+methods fail then the environment variable
+.L LINES
+is used to set
+.I *rows
+and the environment variable
+.L COLUMNS
+is used to set
+.IR *cols .

+.SH DESCRIPTION
+.PP
+\fICdt\fP manages run-time dictionaries using standard container data types:
+unordered set/multiset, ordered set/multiset, list, stack, and queue.
+.PP
+.Ss "DICTIONARY TYPES"
+.PP
+.Ss "  Void_t*"
+This type is used to pass objects between \fICdt\fP and application code.
+\f5Void_t\fP is defined as \f5void\fP for ANSI-C and C++
+and \f5char\fP for other compilation environments.
+.PP
+.Ss "  Dt_t"
+This is the type of a dictionary handle.
+.PP
+.Ss "  Dtdisc_t"
+This defines the type of a discipline structure which describes
+object lay-out and manipulation functions.
+.PP
+.Ss "  Dtmethod_t"
+This defines the type of a container method.
+.PP
+.Ss "  Dtlink_t"
+This is the type of a dictionary object holder (see \f5dtdisc()\fP.)
+.PP
+.Ss "  Dtstat_t"
+This is the type of a structure to return dictionary statistics (see \f5dtstat()\fP.)
+.PP
+.Ss "DICTIONARY CONTROL"
+.PP
+.Ss "  Dt_t* dtopen(const Dtdisc_t* disc, const Dtmethod_t* meth)"
+This creates a new dictionary.
+\f5disc\fP is a discipline structure to describe object format.
+\f5meth\fP specifies a manipulation method.
+\f5dtopen()\fP returns the new dictionary or \f5NULL\fP on error.
+See also the events \f5DT_OPEN\fP and \f5DT_ENDOPEN\fP below.
+.PP
+.Ss "  int dtclose(Dt_t* dt)"
+This deletes \f5dt\fP and its objects.
+Note that \f5dtclose()\fP fails if \f5dt\fP is being viewed by
+some other dictionaries (see \f5dtview()\fP).
+\f5dtclose()\fP returns \f50\fP on success and \f5-1\fP on error.
+See also the events \f5DT_CLOSE\fP and \f5DT_ENDCLOSE\fP below.
+.PP
+.Ss "  void dtclear(Dt_t* dt)"
+This deletes all objects in \f5dt\fP without closing \f5dt\fP.
+.PP
+.Ss "  Dtmethod_t dtmethod(Dt_t* dt, const Dtmethod_t* meth)"
+If \f5meth\fP is \f5NULL\fP, \f5dtmethod()\fP returns the current method.
+Otherwise, it changes the storage method of \f5dt\fP to \f5meth\fP.
+Object order remains the same during a
+method switch among \f5Dtlist\fP, \f5Dtstack\fP and \f5Dtqueue\fP.
+Switching to and from \f5Dtset/Dtbag\fP and \f5Dtoset/Dtobag\fP may cause
+objects to be rehashed, reordered, or removed as the case requires.
+\f5dtmethod()\fP returns the previous method or \f5NULL\fP on error.
+.PP
+.Ss "  Dtdisc_t* dtdisc(Dt_t* dt, const Dtdisc_t* disc, int type)"
+If \f5disc\fP is \f5NULL\fP, \f5dtdisc()\fP returns the current discipline.
+Otherwise, it changes the discipline of \f5dt\fP to \f5disc\fP.
+Objects may be rehashed, reordered, or removed as appropriate.
+\f5type\fP can be any bit combination of \f5DT_SAMECMP\fP and \f5DT_SAMEHASH\fP.
+\f5DT_SAMECMP\fP means that objects will compare exactly the same as before
+thus obviating the need for reordering or removing new duplicates.
+\f5DT_SAMEHASH\fP means that hash values of objects remain the same
+thus obviating the need to rehash.
+\f5dtdisc()\fP returns the previous discipline on success
+and \f5NULL\fP on error.
+.PP
+.Ss "  Dt_t* dtview(Dt_t* dt, Dt_t* view)"
+A viewpath allows a search or walk starting from a dictionary to continue to another.
+\f5dtview()\fP first terminates any current view from \f5dt\fP to another dictionary.
+Then, if \f5view\fP is \f5NULL\fP, \f5dtview\fP returns the terminated view dictionary.
+If \f5view\fP is not \f5NULL\fP, a viewpath from \f5dt\fP to \f5view\fP is established.
+\f5dtview()\fP returns \f5dt\fP on success and \f5NULL\fP on error.
+.PP
+If two dictionaries on the same viewpath have the same values for the discipline fields
+\f5Dtdisc_t.link\fP, \f5Dtdisc_t.key\fP, \f5Dtdisc_t.size\fP, and \f5Dtdisc_t.hashf\fP,
+it is expected that key hashing will be the same.
+If not, undefined behaviors may result during a search or a walk.
+.PP
+.Ss "  int dttreeset(Dt_t* dt, int minp, int balance)"
+This function only applies to dictionaries operated under the method \f5Dtoset\fP
+which uses top-down splay trees (see below). It returns 0 on success and -1 on error.
+.Tp
+\f5minp\fP:
+This parameter defines the minimum path length before a search path is adjusted.
+For example, \f5minp\fP equal 0 would mean that search paths are always adjusted.
+If \f5minp\fP is negative, the minimum search path is internally computed based
+on a function of the current dictionary size. This computed value is such that
+if the tree is balanced, it will never require adjusting.
+.Tp
+\f5balance\fP:
+If this is non-zero, the tree will be made balanced.
+.PP
+.Ss "STORAGE METHODS"
+.PP
+Storage methods are of type \f5Dtmethod_t*\fP.
+\fICdt\fP supports the following methods:
+.PP
+.Ss "  Dtoset"
+.Ss "  Dtobag"
+Objects are ordered by comparisons.
+\f5Dtoset\fP keeps unique objects.
+\f5Dtobag\fP allows repeatable objects.
+.PP
+.Ss "  Dtset"
+.Ss "  Dtbag"
+Objects are unordered.
+\f5Dtset\fP keeps unique objects.
+\f5Dtbag\fP allows repeatable objects and always keeps them together
+(note the effect on dictionary walking.)
+These methods use a hash table with chaining to manage the objects.
+See also the event \f5DT_HASHSIZE\fP below on how to manage hash table
+resizing when objects are inserted.
+.PP
+.Ss "  Dtlist"
+Objects are kept in a list.
+New objects are inserted either
+in front of \fIcurrent object\fP (see \f5dtfinger()\fP) if this is defined
+or at list front if there is no current object.
+.PP
+.Ss "  Dtstack"
+Objects are kept in a stack, i.e., in reverse order of insertion.
+Thus, the last object inserted is at stack top
+and will be the first to be deleted.
+.PP
+.Ss "  Dtqueue"
+Objects are kept in a queue, i.e., in order of insertion.
+Thus, the first object inserted is at queue head
+and will be the first to be deleted.
+.PP
+.Ss "DISCIPLINE"
+.PP
+Object format and associated management functions are
+defined in the type \f5Dtdisc_t\fP:
+.Cs
+    typedef struct
+    { int        key, size;
+      int        link;
+      Dtmake_f   makef;
+      Dtfree_f   freef;
+      Dtcompar_f comparf;
+      Dthash_f   hashf;
+      Dtmemory_f memoryf;
+      Dtevent_f  eventf;
+    } Dtdisc_t;
+.Ce
+.Ss "  int key, size"
+Each object \f5obj\fP is identified by a key used for object comparison or hashing.
+\f5key\fP should be non-negative and defines an offset into \f5obj\fP.
+If \f5size\fP is negative, the key is a null-terminated
+string with starting address \f5*(Void_t**)((char*)obj+key)\fP.
+If \f5size\fP is zero, the key is a null-terminated string with starting address
+\f5(Void_t*)((char*)obj+key)\fP.
+Finally, if \f5size\fP is positive, the key is a byte array of length \f5size\fP
+starting at \f5(Void_t*)((char*)obj+key)\fP.
+.PP
+.Ss "  int link"
+Let \f5obj\fP be an object to be inserted into \f5dt\fP as discussed below.
+If \f5link\fP is negative, an internally allocated object holder is used
+to hold \f5obj\fP. Otherwise, \f5obj\fP should have
+a \f5Dtlink_t\fP structure embedded \f5link\fP bytes into it,
+i.e., at address \f5(Dtlink_t*)((char*)obj+link)\fP.
+.PP
+.Ss "  Void_t* (*makef)(Dt_t* dt, Void_t* obj, Dtdisc_t* disc)"
+If \f5makef\fP is not \f5NULL\fP,
+\f5dtinsert(dt,obj)\fP will call it
+to make a copy of \f5obj\fP suitable for insertion into \f5dt\fP.
+If \f5makef\fP is \f5NULL\fP, \f5obj\fP itself will be inserted into \f5dt\fP.
+.PP
+.Ss "  void (*freef)(Dt_t* dt, Void_t* obj, Dtdisc_t* disc)"
+If not \f5NULL\fP,
+\f5freef\fP is used to destroy data associated with \f5obj\fP.
+.PP
+.Ss "int (*comparf)(Dt_t* dt, Void_t* key1, Void_t* key2, Dtdisc_t* disc)"
+If not \f5NULL\fP, \f5comparf\fP is used to compare two keys.
+Its return value should be \f5<0\fP, \f5=0\fP, or \f5>0\fP to indicate
+whether \f5key1\fP is smaller, equal to, or larger than \f5key2\fP.
+All three values are significant for method \f5Dtoset\fP and \f5Dtobag\fP.
+For other methods, a zero value
+indicates equality and a non-zero value indicates inequality.
+If \f5(*comparf)()\fP is \f5NULL\fP, an internal function is used
+to compare the keys as defined by the \f5Dtdisc_t.size\fP field.
+.PP
+.Ss "  unsigned int (*hashf)(Dt_t* dt, Void_t* key, Dtdisc_t* disc)"
+If not \f5NULL\fP,
+\f5hashf\fP is used to compute the hash value of \f5key\fP.
+It is required that keys compared equal will also have same hash values.
+If \f5hashf\fP is \f5NULL\fP, an internal function is used to hash
+the key as defined by the \f5Dtdisc_t.size\fP field.
+.PP
+.Ss "  Void_t* (*memoryf)(Dt_t* dt, Void_t* addr, size_t size, Dtdisc_t* disc)"
+If not \f5NULL\fP, \f5memoryf\fP is used to allocate and free memory.
+When \f5addr\fP is \f5NULL\fP, a memory segment of size \f5size\fP is requested. 
+If \f5addr\fP is not \f5NULL\fP and \f5size\fP is zero, \f5addr\fP is to be freed.
+If \f5addr\fP is not \f5NULL\fP and \f5size\fP is positive,
+\f5addr\fP is to be resized to the given size.
+If \f5memoryf\fP is \f5NULL\fP, \fImalloc(3)\fP is used.
+When dictionaries share memory,
+a record of the first allocated memory segment should be kept
+so that it can be used to initialize other dictionaries (see below.)
+.PP
+.Ss "  int (*eventf)(Dt_t* dt, int type, Void_t* data, Dtdisc_t* disc)"
+If not \f5NULL\fP, \f5eventf\fP announces various events.
+Each event may have particular handling of the return values from \f5eventf\fP.
+But a negative return value typically means failure.
+Following are the events:
+.Tp
+\f5DT_OPEN\fP:
+\f5dt\fP is being opened.
+If \f5eventf\fP returns negative, the opening process terminates with failure.
+If \f5eventf\fP returns zero, the opening process proceeds normally.
+A positive return value indicates special treatment of memory as follows.
+If \f5*(Void_t**)data\fP is set to point to some memory segment
+as discussed in \f5memoryf\fP, that segment of memory is used to start
+the dictionary. If \f5*(Void_t**)data\fP is not set, this indicates that
+\f5dtopen()\fP should allocate the dictionary handle itself with
+\f5memoryf\fP so that all memories pertained to the dictionary are allocated
+via this function.
+.Tp
+\f5DT_ENDOPEN\fP:
+This event announces that \f5dtopen()\fP has successfully opened
+a dictionary and is about to return. The \f5data\fP argument of
+\f5eventf\fP should be the new dictionary handle itself.
+.Tp
+\f5DT_CLOSE\fP:
+\f5dt\fP is about to be closed. If \f5eventf\fP returns zero,
+the closing process proceeds normally. This means that all objects
+in the dictionary will be deleted and all associated memories freed.
+If \f5eventf\fP returns a positive value, objects will not be deleted.
+However, the dictionary handle itself will still be deallocated
+unless it was allocated via \f5memoryf\fP during \f5dtopen()\fP.
+This allows shared/persistent memory dictionaries to retain
+the relevant memories across dictionary openings and closings.
+.Tp
+\f5DT_ENDCLOSE\fP:
+This event announces that \f5dtclose()\fP has successfully closed
+a dictionary and is about to return.
+.Tp
+\f5DT_DISC\fP:
+The discipline of \f5dt\fP is being changed to a new one given in
+\f5(Dtdisc_t*)data\fP.
+.Tp
+\f5DT_METH\fP:
+The method of \f5dt\fP is being changed to a new one given in
+\f5(Dtmethod_t*)data\fP.
+.Tp
+\f5DT_HASHSIZE\fP:
+The hash table (for \f5Dtset\fP and \f5Dtbag\fP) is being resized.
+In this case, \f5*(int*)data\fP has the current size of the table.
+The application can set the new table size by first changing
+\f5*(int*)data\fP to the desired size, then return a positive value.
+The application can also fix the table size at the current value
+forever by setting \f5*(int*)data\fP to a negative value, then
+again return a positive value. A non-positive return value from
+the event handling function means that Cdt will be responsible
+for choosing the hash table size.
+.PP
+.Ss "#define DTOFFSET(struct_s,member)"
+This macro function computes the offset of \f5member\fP from the start
+of structure \f5struct_s\fP. It is useful for getting the offset of
+a \f5Dtlink_t\fP embedded inside an object.
+.PP
+.Ss "#define DTDISC(disc,key,size,link,makef,freef,comparf,hashf,memoryf,eventf)"
+This macro function initializes the discipline pointed to by \f5disc\fP
+with the given values.
+.PP
+.Ss "OBJECT OPERATIONS"
+.PP
+.Ss "  Void_t* dtinsert(Dt_t* dt, Void_t* obj)"
+This inserts an object prototyped by \f5obj\fP into \f5dt\fP.
+If there is an existing object in \f5dt\fP matching \f5obj\fP
+and the storage method is \f5Dtset\fP or \f5Dtoset\fP,
+\f5dtinsert()\fP will simply return the matching object.
+Otherwise, a new object is inserted according to the method in use.
+See \f5Dtdisc_t.makef\fP for object construction.
+\f5dtinsert()\fP returns the new object, a matching object as noted,
+or \f5NULL\fP on error.
+.PP
+.Ss "  Void_t* dtdelete(Dt_t* dt, Void_t* obj)"
+If \f5obj\fP is \f5NULL\fP, methods \f5Dtstack\fP and \f5Dtqueue\fP
+delete respectively stack top or queue head while other methods do nothing.
+If \f5obj\fP is not \f5NULL\fP, there are two cases.
+If the method in use is not \f5Dtbag\fP or \f5Dtobag\fP,
+the first object matching \f5obj\fP is deleted.
+On the other hand, if the method in use is \f5Dtbag\fP or \f5Dtobag\fP,
+the library check to see if \f5obj\fP is in the dictionary and delete it.
+If \f5obj\fP is not in the dictionary, some object matching it will be deleted.
+See \f5Dtdisc_t.freef\fP for object destruction.
+\f5dtdelete()\fP returns the deleted object (even if it was deallocated)
+or \f5NULL\fP on error.
+.PP
+.Ss "  Void_t* dtattach(Dt_t* dt, Void_t* obj)"
+This function is similar to \f5dtinsert()\fP but \f5obj\fP itself
+will be inserted into \f5dt\fP even if a discipline
+function \f5makef\fP is defined.
+.PP
+.Ss "  Void_t* dtdetach(Dt_t* dt, Void_t* obj)"
+This function is similar to \f5dtdelete()\fP but the object to be deleted
+from \f5dt\fP will not be freed (via the discipline \f5freef\fP function).
+.PP
+.Ss "  Void_t* dtsearch(Dt_t* dt, Void_t* obj)"
+.Ss "  Void_t* dtmatch(Dt_t* dt, Void_t* key)"
+These functions find an object matching \f5obj\fP or \f5key\fP either from \f5dt\fP or
+from some dictionary accessible from \f5dt\fP via a viewpath (see \f5dtview()\fP.)
+\f5dtsearch()\fP and \f5dtmatch()\fP return the matching object or
+\f5NULL\fP on failure.
+.PP
+.Ss "  Void_t* dtfirst(Dt_t* dt)"
+.Ss "  Void_t* dtnext(Dt_t* dt, Void_t* obj)"
+\f5dtfirst()\fP returns the first object in \f5dt\fP.
+\f5dtnext()\fP returns the object following \f5obj\fP.
+Objects are ordered based on the storage method in use.
+For \f5Dtoset\fP and \f5Dtobag\fP, objects are ordered by object comparisons.
+For \f5Dtstack\fP, objects are ordered in reverse order of insertion.
+For \f5Dtqueue\fP, objects are ordered in order of insertion.
+For \f5Dtlist\fP, objects are ordered by list position.
+For \f5Dtset\fP and \f5Dtbag\fP,
+objects are ordered by some internal order (more below).
+Thus, objects in a dictionary or a viewpath can be walked using 
+a \f5for(;;)\fP loop as below.
+.Cs
+    for(obj = dtfirst(dt); obj; obj = dtnext(dt,obj))
+.Ce
+When a dictionary uses \f5Dtset\fP or \f5Dtbag\fP,
+the object order is determined upon a call to \f5dtfirst()\fP/\f5dtlast()\fP.
+This order is frozen until a call \f5dtnext()\fP/\f5dtprev()\fP returns \f5NULL\fP
+or when these same functions are called with a \f5NULL\fP object argument.
+It is important that a \f5dtfirst()/dtlast()\fP call be
+balanced by a \f5dtnext()/dtprev()\fP call as described.
+Nested loops will require multiple balancing, once per loop.
+If loop balancing is not done carefully, either performance is degraded
+or unexpected behaviors may result.
+.Ss "  Void_t* dtlast(Dt_t* dt)"
+.Ss "  Void_t* dtprev(Dt_t* dt, Void_t* obj)"
+\f5dtlast()\fP and \f5dtprev()\fP are like \f5dtfirst()\fP and \f5dtnext()\fP
+but work in reverse order.
+Note that dictionaries on a viewpath are still walked in order
+but objects in each dictionary are walked in reverse order.
+.PP
+.Ss "  Void_t* dtfinger(Dt_t* dt)"
+This function returns the \fIcurrent object\fP of \f5dt\fP, if any.
+The current object is defined after a successful call to one of
+\f5dtsearch()\fP, \f5dtmatch()\fP, \f5dtinsert()\fP,
+\f5dtfirst()\fP, \f5dtnext()\fP, \f5dtlast()\fP, or \f5dtprev()\fP.
+As a side effect of this implementation of \fICdt\fP,
+when a dictionary is based on \f5Dtoset\fP and \f5Dtobag\fP,
+the current object is always defined and is the root of the tree.
+.PP
+.Ss "  Void_t* dtrenew(Dt_t* dt, Void_t* obj)"
+This function repositions and perhaps rehashes
+an object \f5obj\fP after its key has been changed.
+\f5dtrenew()\fP only works if \f5obj\fP is the current object (see \f5dtfinger()\fP).
+.PP
+.Ss "  dtwalk(Dt_t* dt, int (*userf)(Dt_t*, Void_t*, Void_t*), Void_t* data)"
+This function calls \f5(*userf)(walk,obj,data)\fP on each object in \f5dt\fP and
+other dictionaries viewable from it.
+\f5walk\fP is the dictionary containing \f5obj\fP.
+If \f5userf()\fP returns a \f5<0\fP value,
+\f5dtwalk()\fP terminates and returns the same value.
+\f5dtwalk()\fP returns \f50\fP on completion.
+.PP
+.Ss "  Dtlink_t* dtflatten(Dt_t* dt)"
+.Ss "  Dtlink_t* dtlink(Dt_t* dt, Dtlink_t* link)"
+.Ss "  Void_t* dtobj(Dt_t* dt, Dtlink_t* link)"
+Using \f5dtfirst()/dtnext()\fP or \f5dtlast()/dtprev()\fP
+to walk a single dictionary can incur significant cost due to function calls.
+For efficient walking of a single directory (i.e., no viewpathing),
+\f5dtflatten()\fP and \f5dtlink()\fP can be used.
+Objects in \f5dt\fP are made into a linked list and walked as follows:
+.Cs
+    for(link = dtflatten(dt); link; link = dtlink(dt,link) )
+.Ce
+.PP
+Note that \f5dtflatten()\fP returns a list of type \f5Dtlink_t*\fP,
+not \f5Void_t*\fP. That is, it returns a dictionary holder pointer,
+not a user object pointer
+(although both are the same if the discipline field \f5link\fP is zero.)
+The macro function \f5dtlink()\fP
+returns the dictionary holder object following \f5link\fP.
+The macro function \f5dtobj(dt,link)\fP
+returns the user object associated with \f5link\fP,
+Beware that the flattened object list is unflattened on any
+dictionary operations other than \f5dtlink()\fP.
+.PP
+.Ss "  Dtlink_t* dtextract(Dt_t* dt)"
+.Ss "  int dtrestore(Dt_t* dt, Dtlink_t* link)"
+\f5dtextract()\fP extracts all objects from \f5dt\fP and makes it appear empty.
+\f5dtrestore()\fP repopulates \f5dt\fP with
+objects previously obtained via \f5dtextract()\fP.
+\f5dtrestore()\fP will fail if \f5dt\fP is not empty.
+These functions can be used
+to share a same \f5dt\fP handle among many sets of objects.
+They are useful to reduce dictionary overhead
+in an application that creates many concurrent dictionaries.
+It is important that the same discipline and method are in use at both
+extraction and restoration. Otherwise, undefined behaviors may result.

+.Ss "  #define   DTTREEMATCH(Dt_t* dt, Void_t* key, action)"
+These macro functions are analogues of \f5dtsearch()\fP and \f5dtmatch()\fP
+but they can only be used on a dictionary based on a binary
+search tree, i.e., \f5Dtoset\fP or \f5Dtobag\fP.
+.Tp
+\f5obj\fP or \f5key\fP:
+These are used to find a matching object. If there is no match,
+the result is \f5NULL\fP.
+.Tp
+\f5action\fP:
+The matching object \f5o\fP (which may be \f5NULL\fP) will be processed as follow:
+
+.Cs
+    action (o);
+.Ce
+
+Since \f5action\fP is used verbatim, it can be any C code
+fragment combinable with \f5(o)\fP to form a syntactically correct C statement.
+For example, suppose that the matching object is an integer, the below code
+accumulates the integer value in a variable \f5total\fP:
+
+.Cs
+    DTTREEMATCH(dt, key, total += (int));
+.Ce
+
+.PP
+.Ss "DICTIONARY INFORMATION"
+.PP
+.Ss "  Dt_t* dtvnext(Dt_t* dt)"
+This returns the dictionary that \f5dt\fP is viewing, if any.
+.Ss "  int dtvcount(Dt_t* dt)"
+This returns the number of dictionaries that view \f5dt\fP.
+.Ss "  Dt_t* dtvhere(Dt_t* dt)"
+This returns the dictionary \f5v\fP viewable from \f5dt\fP
+where an object was found from the most recent search or walk operation.
+.Ss "  int dtsize(Dt_t* dt)"
+This function returns the number of objects stored in \f5dt\fP.
+.PP
+.Ss "  int dtstat(Dt_t *dt, Dtstat_t* st, int all)"
+This function reports dictionary statistics.
+If \f5all\fP is non-zero, all fields of \f5st\fP are filled.
+Otherwise, only the \f5dt_type\fP and \f5dt_size\fP fields are filled.
+It returns \f50\fP on success and \f5-1\fP on error.
+.PP
+\f5Dtstat_t\fP contains the below fields:
+.Tp
+\f5int dt_type\fP:
+This is one of \f5DT_SET\fP, \f5DT_BAG\fP, \f5DT_OSET\fP, \f5DT_OBAG\fP,
+\f5DT_LIST\fP, \f5DT_STACK\fP, and \f5DT_QUEUE\fP.
+.Tp
+\f5int dt_size\fP:
+This contains the number of objects in the dictionary.
+.Tp
+\f5int dt_n\fP:
+For \f5Dtset\fP and \f5Dtbag\fP,
+this is the number of non-empty chains in the hash table.
+For \f5Dtoset\fP and \f5Dtobag\fP,
+this is the deepest level in the tree (counting from zero.)
+Each level in the tree contains all nodes of equal distance from the root node.
+\f5dt_n\fP and the below two fields are undefined for other methods.
+.Tp
+\f5int dt_max\fP:
+For \f5Dtbag\fP and \f5Dtset\fP, this is the size of a largest chain.
+For \f5Dtoset\fP and \f5Dtobag\fP, this is the size of a largest level.
+.Tp
+\f5int* dt_count\fP:
+For \f5Dtset\fP and \f5Dtbag\fP,
+this is the list of counts for chains of particular sizes.
+For example, \f5dt_count[1]\fP is the number of chains of size \f51\fP.
+For \f5Dtoset\fP and \f5Dtobag\fP, this is the list of sizes of the levels.
+For example, \f5dt_count[1]\fP is the size of level \f51\fP.
+.PP
+.Ss "HASH FUNCTIONS"
+.PP
+.Ss "  unsigned int dtcharhash(unsigned int h, char c)"
+.Ss "  unsigned int dtstrhash(unsigned int h, char* str, int n)"
+These functions compute hash values from bytes or strings.
+\f5dtcharhash()\fP computes a new hash value from byte \f5c\fP and seed value \f5h\fP.
+\f5dtstrhash()\fP computes a new hash value from string \f5str\fP and seed value \f5h\fP.
+If \f5n\fP is positive, \f5str\fP is a byte array of length \f5n\fP;
+otherwise, \f5str\fP is a null-terminated string.
+.PP
+.SH IMPLEMENTATION NOTES
+\f5Dtset\fP and \f5Dtbag\fP are based on hash tables with
+move-to-front collision chains.
+\f5Dtoset\fP and \f5Dtobag\fP are based on top-down splay trees.
+\f5Dtlist\fP, \f5Dtstack\fP and \f5Dtqueue\fP are based on doubly linked list.

+
+int          chresc(const char* \fIs\fP, char** \fIe\fP);
+int          chrtoi(const char* \fIs\fP);
+.EE
+.SH DESCRIPTION
+.L chresc
+converts and returns the next character constant in the 0-terminated string
+.IR s .
+If
+.I e
+is not 0 then
+.I *e
+is set to point to the next character in
+.I s
+on return.
+0 is returned and 
+.I e
+is not modified when the end of
+.I s
+is reached.
+.PP
+.L chrtoi
+converts the 0-terminated string
+.I s
+to an
+.I int
+and returns the value.
+The characters in
+.I s
+are converted in order from the left and shifted into the
+.I int
+value until up to the number of characters in an
+.I int
+is reached.
+This operation is inherently machine-dependent,
+but at least its defined in one place.
+.PP
+The following 
+.B \e
+escape sequences are recognized:
+.TP
+.LI \e ooo
+The character represented by the octal code
+.IR ooo .
+.TP
+.LI \ex xx
+The character represented by the hex code
+.IR xx .
+.TP
+.L \ea
+Alert (bell).
+.TP
+.L \eb
+Backspace.
+.TP
+.L \ef
+Formfeed.
+.TP
+.L \en
+Newline.
+.TP
+.L \er
+Carriage return.
+.TP
+.L \et
+Horizontal tab.
+.TP
+.L \ev
+Vertical tab.
+.TP
+.L \eE
+ESC (escape).
+.TP
+.L \e\e
+Backslash.
+.PP
+Other characters following
+.B \e
+are undefined (although for backwards compatibility they
+translate to themselves).

+.SH DESCRIPTION
+These routines are described in the ANSI C, POSIX, BSD and System V manual
+sections 2 and 3.
+The interfaces are preserved and present in all libast implementations.
+Where conflicts exist the POSIX syntax and semantics are implied.
+The appropriate error value is returned and

+is set to
+.L EINVAL
+when emulation is either too expensive or not possible.
+.SH CAVEATS
+If you
+.L "#undef foo"
+and then call
+.L foo
+you may end up with the local implementation of
+.LR foo ,
+and then you get what you payed for.

+Error_info_t error_info;
+
+void         error(int \fIlevel\fP, ...);
+void         errorv(const char* \fIlibrary\fP, int \fIlevel\fP, va_alist \fIargs\fP);

+libmessage((const char* \fIlibrary\fI, int \fIlevel\fP, ...))
+.EE
+.SH DESCRIPTION
+.L error
+is the error and debug trace message formatter.
+.I level
+is the severity level.
+Messages with
+.I "level < error_info.trace"
+are suppressed.
+.I error_info.trace
+is initially
+.LR 0 .
+The remaining arguments are passed on to
+.LR printf .
+A
+.I newline
+is appended to the message text, so none should appear in the
+.L printf
+format.
+If 
+.I error_info.id
+is not
+.L 0
+then messages with
+.I "level > 0"
+are prefixed by
+.IR error_info.id: .
+.PP
+Before the message text is output to standard error
+it is passed to the function
+.LR "char* ERROR_translate(const char* \fItext\fP, int \fIflag\fP)" .
+By default
+.L ERROR_translate
+returns the
+.L text
+argument, but on some systems it may do language translation via lookup
+on the original source text.
+.RL ( error
+calls 
+.L ERROR_translate
+with a 0
+.L flag
+argument).
+.PP
+.I level
+may be one of:
+.TP
+.B <0
+Negative values are for debug tracing.
+Debug messages are prefixed with
+.BI debug level.
+If
+.I "errno != error_info.last_errno"
+then 
+.I error_info.last_errno
+is set to
+.I errno
+and the error text for errno is appended to the message.
+.TP
+.B "ERROR_INFO [0]"
+Information only; no prefixes are added to the message.
+.TP
+.B "ERROR_WARNING [1]"
+.L "warning:"
+is added after
+.L error_info.id
+and
+.I error_info.warnings
+is incremented.
+.TP
+.I "ERROR_ERROR [2]"
+(soft error)
+.I error_info.errors
+is incremented.
+.TP
+.B ">= ERROR_FATAL [3]"
+(hard error)
+.I error_info.errors
+is incremented and
+.L exit(\fIlevel\fP\-2)
+is called after the message is emitted.
+.TP
+.B "ERROR_PANIC [77]"
+(unrecoverable internal error)
+.L "panic:"
+is added after
+.IR error_info.id .
+.PP
+The following may be inclusive-or'd into
+.I level
+for alternate behavior:
+.TP
+.L ERROR_SYSTEM
+The error text for
+.I errno
+is appended to the message.
+.TP
+.L ERROR_OUTPUT
+The next argument is the file descriptor where the error message
+should be emitted.
+.TP
+.L ERROR_SOURCE
+Then next two arguments are a file name and line number that are added
+to the message after
+.IR error_info.id .
+.TP
+.L ERROR_USAGE
+A usage message is emitted.
+.TP
+.L ERROR_PROMPT
+The trailing 
+.I newline
+is suppressed.
+.TP
+.L ERROR_NOID
+The
+.I error_info.id
+prefix is suppressed.
+.TP
+.L ERROR_LIBRARY
+The message is from a library routine.
+.SH ENVIRONMENT
+The elements of the global struct
+.I error_info
+control error output and actions.
+Parts of 
+.I error_info
+can be initialized from the
+.L ERROR_OPTIONS
+environment variable.
+.L ERROR_OPTIONS
+contains space separated
+.IR name [ =value ]
+options, described below.
+.TP
+.I "int core"
+If
+.I "error_info.core != 0"
+then 
+.I "level >= error_info.core"
+generates a core dump.
+Initialized by
+.EX
+ERROR_OPTIONS="core=\fIlevel\fP"
+.EE
+where 
+.I level
+can be a number or one of
+.LR error ,
+.LR fatal ,
+or
+.LR panic .
+.I error_info.core
+is a handy way to get a stack trace at the exact point of error.
+.TP
+.I "int error_info.trace"
+If
+.I "error_info.trace != 0"
+and
+.I "level < error_info.trace"
+then the error message text is suppressed.
+.L exit()
+may still be called if appropriate for
+.IR level .
+Initialized by
+.EX
+ERROR_OPTIONS="trace=\fIlevel\fP"
+.EE
+where
+.I error_info.trace
+is set to the negative of
+.IR level .
+.PP
+Library error messages, suppressed by default, are enabled by
+.EX
+ERROR_OPTIONS="library"
+.EE
+The system
+.I errno
+message text can be forced for each message by
+.EX
+ERROR_OPTIONS="system"
+.EE
+.SH "EXTENDED DESCRIPTION"
+.L "<debug.h>"
+provides debugging message macros when
+.L DEBUG
+or
+.L _TRACE_
+are defined
+.RL ( _TRACE_

+and string entities.
+Some routines may cache information to speed up the next call.
+Most of the routines return a pointer to a private buffer, the
+contents of which are overwritten on the next call to that routine.
+Most
+.L fmt
+routines have a corresponding
+.L str
+routine that converts in the other direction.
+There is nothing spectacular about this collection other than that
+it provides a single place where the exact format is spelled out.
+.PP
+.L fmtbase
+formats a base
+.I base
+representation for
+.IR number .
+If
+.I "prefix != 0"
+then the base prefix is included in the formatted string.
+If
+.I "number == 0"
+or
+.I "base == 0"
+then the output is signed base 10.
+.PP
+.L fmtdev
+returns the device handle name specified by the
+.L stat
+structure
+.IR st .
+This is the device information displayed by
+.IR "ls \-l" .
+.PP
+.L fmtelapsed
+formats the elapsed time for
+.I (count/persec)
+seconds.
+The two largest time units are used, limiting the return value length
+to at most 6 characters.
+The units are:
+.TP
+.B s
+seconds
+.TP
+.B m

+returns the system error message text for the error number
+.IR errno .
+.PP
+.L fmtesc
+formats non-ASCII characters in
+.I string
+into C-style
+.B \e
+sequences.
+These sequences are understood by
+.L chresc
+and
+.LR chrtoi .

+
+
+int ftwflags(void);
+\fR
+.fi
+.SH DESCRIPTION
+.PP
+\fIFtwalk\fR traverses a directory hierarchy using depth-first search.
+Upon visiting each file or directory in the hierarchy, it calls
+the user function \fIuserf\fP to process that file or directory.
+On a directory object, \fIuserf\fR may be called twice, once in preorder
+and once in postorder.
+On a terminal object such as a file or an unreadable directory,
+\fIuserf\fP is called only once.
+Cycles due to hard links or symbolic links are detected
+to avoid infinite loops.
+.PP
+\fIPath\fR is the starting point of the search.
+It may be an absolute path name or a path name relative to
+the current directory.
+If \fIpath\fR is a null pointer or points to an empty string, it is treated
+as if it points to the current (dot) directory.
+.PP
+\fIOptions\fR consists of zero or more of the following bits:
+.IP
+FTW_CHILDREN:
+This implies preorder calls to \fIuserf\fR on directory objects.
+On such a call to \fIuserf\fR,
+the field \fIftw->link\fR (below) points to a link list of
+the children of the respective directory.
+Upon returning from \fIuserf\fP,
+if the field \fIftw->status\fR of any child object
+is set to FTW_SKIP (below), that child is pruned from the search.
+.IP
+FTW_DELAY: When \fBFTW_CHILDREN\fP is turned on,
+the fields \fIftw->statb\fP (\fIstruct stat\fP) of children objects
+remain undefined until these objects are visited.
+.IP
+FTW_DOT: Do not use \fIchdir\fR(2) during the traversal.
+Normally \fIchdir\fR is used so that
+the base name of the object about to be processed can be used
+in accessing its data.
+This can enhance \fIftwalk\fR efficiency but certain program effects
+such as core dumps may be generated in unexpected places
+or may not even be generated at all.
+Whenever \fIchdir\fR generates an error, if possible,
+the current directory is restored to the starting directory
+(see FTW_NAME and FTW_PATH).
+.IP
+FTW_MULTIPLE: The \fIpath\fP argument is treated as a \fIchar**\fP
+pointer to a null-terminated array of path names.
+All hierarchies rooted at these paths will be searched
+.IP
+FTW_POST: Calls to the user function are issued only in postorder.
+That is, \fIuserf\fP is called on a directory only after its descendants have
+been processed.
+The absence of this bit indicates that calls to the user functions
+are issued in preorder. That is, \fIuserf\fP is
+called on a directory before its descendants  are processed.
+.IP
+FTW_PHYSICAL: Use \fIlstat\fR(2) instead of \fIstat\fR(2) to get
+file status and allow detection of symbolic links.
+In addition, if each component
+of the absolute path to the starting object has search permission,
+the absolute path is used for early detection of cycles.
+.IP
+FTW_META|FTW_PHYSICAL: Use \fIstat\fR(2) for top level file status and
+\fIlstat\fR(2) for all other files.
+Used to implement the POSIX
+.B \-H
+option for commands like
+.IR ls .
+.IP
+FTW_TWICE: Calls to the user function are issued in both preorder and postorder
+for directory objects.
+.IP
+FTW_USER: The first of 6 user defined option bits.
+These bits are ignored by \fIftwalk\fP.
+.PP
+\fIUserf\fR is a user supplied function that is
+called upon different visits of an object.
+If the return value of \fIuserf\fR is non-zero,
+\fIftwalk\fR returns immediately with the same value.
+The \fIuserf\fP prototype is:
+.PP
+.nf
+	int userf(struct FTW* ftw)
+.fi
+.PP
+\fBstruct FTW\fP contains at least the following elements:
+.PP
+.nf
+    struct FTW*    link;    /* link list of children */
+    struct FTW*    parent;  /* parent object on the search path */
+    union
+    {
+    long           number;  /* local number */
+    void*          pointer; /* local pointer */
+    }              local;   /* user defined */
+    struct stat    statb;   /* stat buffer of this object */
+    char*          path;    /* full pathname */
+    short          pathlen; /* strlen(path) */
+    unsigned short info;    /* type of object */
+    unsigned short status;  /* status of object */ 
+    short          level;   /* depth of object on the search path */
+    short          namelen; /* strlen(name) */
+    char           name[];  /* file name of object */
+.fi
+.PP
+The \fIlink\fR field is normally NULL.
+If the option FTW_CHILDREN was turned on,
+it points to the start of the list of children
+of the directory being visited in preorder.
+Finally, if the directory being visited causes a cycle,
+\fIlink\fR points to the object on the search path that is
+identical to this directory. Note that if FTW_PHYSICAL was turned on,
+this may point to a directory that is an ancestor of the starting
+object.
+.PP
+The \fIparent\fR field points to the parent object
+on the search path. For convenience, a parent object is also supplied for
+the starting object.
+In this case, except for the \fIlocal\fR field which is initialized
+to 0 and the \fIlevel\fR field which contains a negative number,
+the rest of the structure may be undefined.
+.PP
+The \fIinfo\fR field indicates the type of the object
+being visited and the type of the visit. The types are:
+.IP
+FTW_D: A directory being visited in preorder, i.e.,
+none of its children has been visited by the search.
+.IP
+FTW_DNX: A directory being visited in preorder that does not have
+search permission.
+.IP
+FTW_DP: A directory being visited in postorder, i.e., all of its
+descendants have been completely processed.
+.IP
+FTW_DC: A directory that causes cycles. This is a terminal object.
+.IP
+FTW_DNR: A directory that cannot be opened for reading. This is a terminal object.
+.IP
+FTW_F: An ordinary file.
+.IP
+FTW_SL: A symbolic link.
+Unless FTW_FOLLOW (below) is issued by the user function,
+this object is terminal.
+.IP
+FTW_NS: \fIStat\fR failed on this object.
+The stat buffer \fIstatb\fR is undefined.
+This object is terminal.
+.PP
+The \fIstatus\fR field of \fIstruct FTW\fR is used to communicate information
+between \fIftwalk\fR and \fIuserf\fR. On calls to \fIuserf\fR, it has one of
+two values:
+.IP
+FTW_NAME: The name of the object as defined in \fIftw->name\fR should be used for
+accessing its file information. This is because \fIchdir\fR(2) has been used
+to set the current directory to a suitable place (see FTW_CHDIR).
+.IP
+FTW_PATH: The argument \fIpath\fR of \fIuserf\fR should be used
+for accessing the file information of the object.
+.PP
+Upon returning, \fIuserf\fR may set the \fIstatus\fR field
+to one of the following values:
+.IP
+FTW_AGAIN: If this is a directory object being visited in postorder,
+it will be processed \fIagain\fR as if it had not been visited.
+.IP
+FTW_NOPOST: If this is a directory object being visited in preorder,
+the user function will not be called on its postorder visit.
+.IP
+FTW_SKIP: This object and its descendants are pruned from the search.
+.IP
+FTW_FOLLOW: If this object is a symbolic link,
+follow the link to its physical counterpart.
+.PP
+\fIComparf\fR, if not NULL, is a pointer to a function
+used to define a search ordering for children of a directory.
+If FTW_CHILDREN is turned on, the ordering of the children of
+a directory is done before the preorder call to \fIuserf\fR on that directory.
+Therefore, in that case, \fIftw->link\fR will point to the smallest child.
+.PP
+The \fIcomparf\fP prototype is:
+.PP
+.nf
+	int comparf(struct FTW* ftw1, struct FTW* ftw2)
+.fi
+.PP
+\fIComparf\fR should return a value <0, 0, or >0 to indicate whether
+\fIftw1\fR is considered smaller, equal, or larger than \fIftw2\fR.
+.PP
+\fIFtwalk\fR normally returns 0.
+On hard errors such as running out of memory, it returns -1.
+\fIFtwalk\fR may also return other values as discussed with respect
+to \fIuserf\fR. 
+.PP
+\fIFtwflags\fR returns a combination of \fB0, FTW_META, FTW_PHYSICAL\fR
+according to the
+preferences specified by
+\fBastconf("PATH_RESOLVE",0,0)\fR:
+.TP
+.B logical
+0
+.TP
+.B metaphysical
+.B "FTW_META|FTW_PHYSICAL"
+.TP
+.B physical
+.B FTW_PHYSICAL
+.SH HISTORY
+\fIFtwalk\fR performs similar functions as that of
+the routine \fIftw\fR provided in System V.
+However, it is more general than \fIftw\fR
+and suitable for use as a base in implementing
+popular tools such as \fIls, find, tar, du,\fR and \fIrm\fR.
+\fIFtwalk\fR also handles symbolic links and hard links gracefully.

+.TH HASH 3
+.SH NAME
+hash \- hash table support \- obsolete \- use \fBcdt\fP
+.SH SYNOPSIS
+.L "#include <hash.h>"
+.SH DESCRIPTION
+The
+.I hash
+routines manipulate collections of dynamic, scoped hash tables.
+.PP
+A hash table provides an association between a
+.I key
+and its
+.IR value .
+A
+.I key
+is a sequence of 
+.L char
+elements and a
+.I value
+is a user supplied pointer to the value.
+Each hash table has a dynamic number of slots,
+each pointing to the head of a forward linked
+.IR "collision chain" .
+.PP
+Hashing occurs as follows:
+a
+.I "hash function"
+takes a
+.I key
+as an argument and returns a non-negative index.
+The index modulo the table size produces a
+slot that points to a
+.IR "collision chain" .
+The collision chain is sequentially searched until a match is found for
+.IR key .
+The hash tables are automatically resized as new entries are added.
+.PP
+Each hash table has one key type.
+The default key type is a pointer to a null-terminated string.
+The alternate key type is a pointer to a fixed length byte buffer,
+declared for a given table by the
+.L hashalloc()
+function described below.
+.PP
+Hash table information is partitioned into two parts for efficient scoping.
+The
+.I root

+.L MAGIC_VERBOSE
+Enable verbose error messages.
+.PP
+.L magicclose
+closes the magic session.
+.PP
+.L magicload
+loads the magic file named by
+.I path
+into the magic session.
+.I flags
+are the same as with 
+.LR magicopen .
+More than one magic file can be loaded into a session;
+the files are searched in load order.
+If
+.I path
+is 
+.L 0
+then the default magic file is loaded.
+.PP
+.L magiclist
+lists the magic file contents on the

+.IR sp .
+This is used for debugging magic entries.
+.PP
+.L magictype
+returns the type string for
+.I path
+with optional
+.IR stat (2)

+.IR st .
+If
+.I "st == 0"
+then
+.L magictype
+calls
+.L stat
+on a private stat buffer,
+else if

+was called with the
+.L MAGIC_STAT
+flag then
+.I st
+is assumed to contain valid stat information, otherwise
+.L magictype
+calls 
+.L stat
+on
+.IR st .
+.L magictype
+always returns a non-null string.
+If errors are encounterd on
+.I path
+then the return value will contain information on those errors, e.g.,
+.LR "cannot stat" .
+.SH FORMAT
+The magic file format is a backwards compatible extension of an
+ancient System V file implementation.
+However, with the extended format it is possible to write a single
+magic file that works on all platforms.
+Most of the net magic files floating around work with
+.LR magic ,
+but they usually double up on 
+.I le
+and
+.I be
+entries that are automatically handled by
+.LR magic .
+.PP
+A magic file entry describes a procedure for determining a single file type
+based on the file pathname,
+.I stat (2)
+information, and the file data.
+An entry is a sequence of lines, each line being a record of
+.I space
+separated fields.
+The general record format is:
+.EX
+[op]offset type [mask]expression description [mimetype]
+.EE
+.L #
+in the first column introduces a comment.
+The first record in an entry contains no
+.LR op ;
+the remaining records for an entry contain an
+.LR op .
+Integer constants are as in C:
+.L 0x*
+or
+.L 0X*
+for hexadecimal,
+.L 0*
+for octal and decimal otherwise.
+.PP
+The
+.L op
+field may be one of:
+.TP
+.L +
+The previous records must match but the current record is optional.
+.L >
+is an old-style synonym for
+.LR + .
+.TP
+.L &
+The previous and current records must match.
+.TP
+.L {
+Starts a nesting block that is terminated by
+.LR } .
+A nesting block pushes a new context for the
+.L +
+and
+.L &
+ops.
+The
+.L {
+and
+.L }
+records have no other fields.
+.TP
+\fIid\f5{\fR
+A function declaration and call for the single character identifier
+.IR id .
+The function return is a nesting block end record
+.LR } .
+Function may be redefined.
+Functions have no arguments or return value.
+.TP
+\fIid\f5()\fR
+A call to the function
+.IR id .
+.PP
+The
+.L offset
+field is either the offset into the data upon which the current entry operates
+or a file metadata identifier.
+Offsets are either integer constants or offset expressions.
+An offset expression is contained in (...) and is a combination of
+integral arithmetic operators and the 
+.L @
+indirection operator.
+Indirections take the form
+.LI @ integer
+where integer is the data offset for the indirection value.
+The size of the indirection value is taken either from one of the suffixes
+.LR B (byte, 1 char),
+.LR H (short, 2 chars),
+.LR L (long, 4 chars),
+pr
+.LR Q (quead, 8 chars),
+or from the
+.L type 
+field.
+Valid file metadata identifiers are:
+.TP
+.L atime
+The string representation of
+.LR stat.st_atime .
+.TP
+.L blocks
+.LR stat.st_blocks .
+.TP
+.L ctime
+The string representation of
+.LR stat.st_ctime .
+.TP
+.L fstype
+The string representation of
+.LR stat.st_fstype .
+.TP
+.L gid
+The string representation of
+.LR stat.st_gid .
+.TP
+The
+.L stat.st_mode
+file mode bits in
+.IR modecanon (3)
+canonical representation (i.e., the good old octal values).
+.TP
+.L mtime
+The string representation of
+.LR stat.st_mtime .
+.TP
+.L nlink
+.LR stat.st_nlink .
+.TP
+.L size
+.LR stat.st_size .
+.TP
+.L name
+The file path name sans directory.
+.TP
+.L uid
+The string representation of
+.LR stat.st_uid .
+.PP
+The
+.L type
+field specifies the type of the data at
+.LR offset .
+Integral types may be prefixed by
+.L le
+or
+.L be
+for specifying exact little-endian or big-endian representation,
+but the internal algorithm automatically loops through the
+standard representations to find integral matches,
+so representation prefixes are rarely used.
+However, this looping may cause some magic entry conflicts; use the
+.L le
+or
+.L be
+prefix in these cases.
+Only one representation is used for all the records in an entry.
+Valid types are:
+.TP
+.L byte
+A 1 byte integer.
+.TP
+.L short
+A 2 byte integer.
+.TP
+.L long
+A 4 byte integer.
+.TP
+.L quad
+An 8 byte integer.
+Tests on this type may fail is the local compiler does not support
+an 8 byte integral type and the corresponding value overflows 4 bytes.
+.TP
+.L date
+The data at
+.L offset
+is interpreted as a 4 byte seconds-since-the-epoch date and
+converted to a string.
+.TP
+.L edit
+The
+.L expression
+field is an
+.IR ed (1)
+style substitution expression
+\fIdel old del new del \fP [ \fI flags \fP ]
+where the substituted value is made available to the
+.L description
+field
+.L %s
+format.
+In addition to the
+.I flags
+supported by
+.IR ed (3)
+are
+.L l
+that converts the substituted value to lower case and
+.L u
+that converts the substituted value to upper case.
+If
+.I old
+does not match the string data at
+.L offset
+then the entry record fails.
+.TP
+.L match
+.L expression
+field is a
+.IR strmatch (3)
+pattern that is matched against the string data at
+.LR offset .
+.TP
+.L string
+The
+.L expression
+field is a string that is compared with the string data at
+.LR offset .
+.PP
+The optional
+.L mask
+field takes the form
+.LI & number
+where
+.I number
+is 
+.I anded
+with the integral value at
+.L offset
+before the
+.L expression
+is applied.
+.PP
+The contents of the expression field depends on the
+.LR type .
+String type expression are described in the
+.L type
+field entries above.
+.L *
+means any value and applies to all types.
+Integral
+.L type
+expression take the form [\fIoperator\fP] \fIoperand\P where 
+.I operand
+is compared with the data value at
+.L offset
+using
+.IR operator .
+.I operator 
+may be one of
+.LR < .
+.LR <= ,
+.LR == ,
+.LR >=
+or
+.LR > .
+.I operator
+defaults to
+.L ==
+if omitted.
+.I operand 
+may be an integral constant or one of the following builtin function calls:
+.TP
+.L magic()
+A recursive call to the magic algorithm starting with the data at
+.LR offset .
+.TP
+\f5loop(\fIfunction\fP,\fIoffset\fP,\fIincrement\fP)\fR
+Call 
+.I function
+starting at
+.I offset
+and increment
+.I offset
+by
+.I increment
+after each iteration.
+Iteration continues until the description text does not change.
+.PP
+The
+.L description
+field is the most important because it is this field that is presented
+to the outside world.
+When constructing description
+fields one must be very careful to follow the style layed out in the
+magic file, lest yet another layer of inconsistency creep into the system.
+The description for each matching record in an entry are concatenated
+to form the complete magic type.
+If the previous matching description in the current entry does not end with
+.I space
+and the current description is not empty and does not start with
+.I comma ,
+.I dot
+or
+.I backspace
+then a
+.I space
+is placed between the descriptions
+(most optional descriptions start with
+.IR comma .)
+The data value at 
+.L offset
+can be referenced in the description using
+.L %s
+for the string types and
+.L %ld
+or
+.L %lu
+for the integral types.
+.PP
+The
+.L mimetype
+field specifies the MIME type, usually in the form
+.IR a / b .

+.EE
+.SH DESCRIPTION
+POSIX threw out the file type bit macros and replaced them with
+function-like macros that test file type.
+This is bad in many ways, the worst of which is that it provides
+no way for a user program to synthesize file types in the mode bits.
+.IR pax (1),
+.IR tar (1)
+and
+.IR cpio (1)
+are examples of user programs that must convert between the internal mode
+representation and a private external representation.
+These routines provide a canonical external representation
+with macros to access and synthesize the bits in the external
+representation.
+.PP
+.L modei
+takes an external mode representation
+.I external
+and returns the equivalent internal representation.
+.PP
+.L modex
+takes an internal mode representation
+.I internal
+and returns the equivalent external representation.
+.PP
+The traditional bit access macro (\f5S_\fP prefix changes to \f5X_\fP) are:
+.L X_IFMT ,
+.L X_IFSOCK ,
+.L X_IFLNK ,
+.L X_IFCTG ,
+.L X_IFREG ,

+.SH DESCRIPTION
+These routines operate on file path names.
+Path buffers are assumed to be of size
+.LR PATH_MAX .
+.L <ast.h>
+always defines
+.LR PATH_MAX ,
+even if it indeterminant on the local system.
+Yes, this was probably a bad choice, but it was made about 10 years ago.
+We will probably move to a <stk.h> based implementation.
+.PP
+.L pathaccess
+constructs a path in
+.L path
+to the file
+.L a/b
+with access
+.L mode
+using the
+.L :
+separated directories in 
+.IR dirs .
+Both
+.I a
+and
+.I b
+may be
+.LR 0 .
+.L mode
+is the inclusive-or of:
+.TP
+.L F_OK
+File exists.
+.TP
+.L R_OK
+Read permission on file.
+.TP
+.L W_OK
+Write permission on file.
+.TP
+.L X_OK
+Execute permission on file.
+.TP
+.L PATH_REGULAR
+A regular file.
+.TP
+.L PATH_ABSOLUTE
+Generated path name is rooted at
+.LR / .
+.I path 
+is returned, 0 on error.
+.PP
+.L pathbin
+returns a pointer to the 
+.L :
+separated list of directories to search for executable commands.
+The
+.L PATH
+environment variable is first consulted.
+If not defined then
+.L confstr(_CS_PATH,...)
+is used.
+A valid string is always returned.
+.PP
+.L pathcanon
+canonicalizes the path
+.I path
+in place.
+A pointer to the trailing 0 in the canonicalized path is returned.
+A canonical path has:
+redundant 
+.L .
+and
+.L /
+removed;
+.L ..
+moved to the front;
+.L /..
+preserved for super root hacks;
+.L ...
+resolved if
+.IR fs3d (3)
+is enabled.
+.I flags is the inclusive-or of:
+.TP
+.L PATH_DOTDOT
+Each
+.L ..
+is checked for access.
+.TP
+.L PATH_EXISTS
+Path must exist at each component.
+.TP
+.L PATH_PHYSICAL
+Symbolic links are resolved at each component.
+.PP
+0 is returned on error.
+If an error occurs and either of
+.L PATH_DOTDOT
+or
+.L PATH_EXISTS 
+is set then
+.I path
+will contain the components following the failure point.
+.PP
+.L pathcat
+concatenates the first
+.I sep
+separated path component in
+.I dirs
+with the path components
+.I a
+and
+.I b
+into
+.LR path .
+The path is constructed in
+.I path
+by separating each path component with
+.IR / .
+Both
+.I a

+.SH NAME
+preroot \- preroot support
+.SH SYNOPSIS
+.EX
+#include <preroot.h>
+
+char*    getpreroot(char* \fIpath\fP, char* \fIcmd\fP);
+int      ispreroot(char* \fIdir\fP);
+int      realopen(char* \fIpath\fP, int \fImode\fP, int \fIperm\fP);
+void     setpreroot(char** \fIargv\fP, char* \fIdir\fP);
+.EE
+.SH DESCRIPTION
+The
+.I preroot
+routines manipulate the process preroot.
+.I preroot
+is a kernel supported per-process two level viewpath.
+All pathnames rooted at
+.L /
+are first searched for in the process preroot directory
+and then in the system root directory.
+Setting the process preroot is a priveleged operation controlled by the
+.IR /etc/preroot (1)
+command.
+.PP
+.L <preroot.h>
+defines the symbol
+.B FS_PREROOT
+for those systems that support preroot.
+The following routines are valid only when
+.B FS_PREROOT
+is defined:
+.TP
+.L getpreroot
+returns a pointer to the absolute pathname of the preroot directory
+for the executable
+.IR cmd .
+The result is placed in
+.IR path .
+If
+.I path
+is
+.B 0
+then
+.IR malloc (3)
+is used to allocate the pathname space.
+.B 0
+is returned if
+.I cmd
+has no preroot or if an error was encountered.
+In this case
+.I errno
+is set to indicate the error.
+.TP
+.L ispreroot
+Non-zero is returned if 
+.I dir
+is the current process preroot.
+If 
+.I dir
+is
+.B 0
+then non-zero is returned if the current process has a preroot.
+.TP
+.L realopen
+temporarily disables the process preroot and does an
+.IR open (3)
+relative to the system root directory.
+The return value from
+.I open
+is returned.
+If there is no preroot then
+.I realopen
+is equivalent to
+.IR open .
+.TP
+.L setpreroot
+calls
+.IR execvp (3)
+as
+.L "execvp(a\fIrgv\fP[0],\fIargv\fP)"
+with the process preroot set to
+.IR dir .
+.I argv
+must be a
+.BR 0 -terminated
+argument array.
+If 
+.I argv
+is
+.B 0
+then the value of
+.I opt_argv
+from
+.IR optget (3)
+is used.
+.L setpreroot
+returns immediately if
+.I dir
+is already the process preroot.
+.SH "SEE ALSO"
+/etc/preroot(1)
+.SH BUGS
+Preroot semantics should be preserved when reading directories.
+The
+.I ast
+.IR directory (3)
+routines do this.
+.IR 3d (1)
+viewpathing does 
+.I preroot
+the right way.

+.EE
+.SH DESCRIPTION
+These routines provide a portable interface to process creation and execution.
+They work on systems with
+.IR fork (2)
+and
+.IR exec (2)
+as well as on systems with only
+.IR spawnve (2)
+or
+.IR spanwveg (3).
+.PP
+.L procopen
+runs
+.I command
+with arguments
+.IR argv ,
+environment modifications in
+.IR envv ,
+file descriptor, signal and process group operations in
+.I opv
+and flags in
+.IR flags .
+.PP
+.I command
+is searched for using the 
+.L PATH
+environment variable from the calling environment.
+If
+.I command
+is 
+.L 0
+then the current shell is used (see
+.IR pathshell (3)).
+If
+.I envv
+is not
+.L 0
+then it is a 
+.L 0
+terminated vector of
+\fIname\fP[=\fIvalue\fP]
+strings that are added to the
+.I command
+environment using
+.IR setenviron (3).
+If
+.I name
+appears in the parent environment then its value is replaced with the new
+.IR value .
+If
+.RI = value
+is omitted then
+.I name
+is removed from the child environment.
+The
+.L _
+environment variable is set to contain the pathname for
+.I command
+and will appear at the top of the child environment.
+.PP
+If
+.I opv
+is not 
+.L 0
+then it is a 0 terminaled vector of operations to perform.
+In the following
+.I context
+is a combination of
+.L PROC_FD_CHILD
+and
+.L PROC_FD_PARENT
+for the child and parent process context respectively.
+Valid operations are:
+.TP
+\f5PROC_FD_CLOSE(\fIfd\fP,\fIcontext\fP)\fR
+The file descriptor
+.I fd
+is closed in
+.IR context .
+.TP
+\f5PROC_FD_DUP(\fIfrom\fP,\fIto\fP,\fIcontext\fP)\fR
+The file descriptor
+.I from
+is 
+.IR dup (2)'d
+into the file descriptor
+.I to

+.IR context .
+.TP
+\f5PROC_SIG_DFL(\fIsig\fP)\fR
+The signal handler for
+.I sig
+is set to
+.L SIG_DFL
+in the child context.
+.TP
+\f5PROC_SIG_IGN(\fIsig\fP)\fR
+The signal handler for
+.I sig
+is set to
+.L SIG_IGN
+in the child context.
+.TP
+\f5PROC_SYS_PGRP(\fIpgid\fP)\fR
+The child process group is set to
+.IR pgid .
+.I pgid 
+may have the following values:
+.TP
+.L <0
+The child process becomes a session leader.
+.TP
+.L 0
+The child process is in the parent process group.
+.TP
+.L 1
+The child process becomes a process group leader.
+.TP
+.L >1
+The child process joins the process group
+.IR pgid .
+.TP
+\f5PROC_SYS_UMASK(\fImask\fP)\fR
+The child process group file creation mask is set to
+.IR mask .
+.PP
+.I flags
+is the inclusive-or of the following:
+.TP
+.L PROC_ARGMOD
+.I "argv[-1]"
+and
+.I "argv[0]"
+may be modified.
+This is an optimization that avoids an environment vector
+.I realloc(3)
+when
+.I command
+is a shell script.
+.TP
+.L PROC_BACKGROUND
+Standard shell 
+.L &
+setup is done for the child process.
+.TP
+.L PROC_CLEANUP
+Parent process redirection file discriptors are closed on error.
+.TP
+.L PROC_DAEMON
+Standard daemon setup is done for the child process.
+.TP
+.L PROC_ENVCLEAR
+The child environment is cleared before

+The child effective group id is set to the real group id.
+.TP
+.L PROC_IGNORE
+Parent pipe errors are ignored.
+.TP
+.L PROC_OVERLAY
+The current process is overlayed by
+.I command
+if possible
+(i.e., the
+.IR fork (2)
+call is omitted).
+.TP
+.L PROC_PARANOID
+Paranoid:
+.I command
+is searched using the default standard
+.LR PATH ;
+the child environment variable
+.L PATH
+is set to the default standard;
+the
+.L PROC_GID
+and
+.L PROC_UID
+modes are set;
+only
+.L /bin/sh
+is used to execute
+.I command
+if it is a shell script.
+.TP
+.L PROC_PRIVELEGED
+If the effective user id is
+.L 0
+then the child real user id is set to 
+.L 0

+.IR command 's
+standard output.
+.TP
+.L PROC_SESSION
+The child process becomes a session group leader.
+(Equivalent to the
+.I opv
+entry
+.LR PROC_SYS_PGRP(-1) .)
+.TP
+.L PROC_UID
+The child effective user id is set to the real user id.
+.TP
+.L PROC_WRITE
+.I proc.wfd
+is connected to

+A read file descriptor connected to
+.IR command 's
+standard output.
+.TP
+.L "int \fIwfd\fP"
+A write file descriptor connected to
+.IR command 's
+standard input.
+.PP
+If an error occurs then
+.L 0
+is returned.
+.PP
+.L procclose

+.SH DESCRIPTION
+.L recomp
+compiles a regular expression in
+.I pattern
+and returns a pointer to the compiled regular expression.
+The space is allocated by
+.IR malloc (3)
+and may be released by
+.LR refree .
+Regular expressions are as in
+.IR egrep (1)
+except that newlines are treated as ordinary
+characters and
+.L $
+matches the end of a null-terminated string.
+.I flags
+may be
+.L RE_EDSTYLE
+which specifies

+and
+.L \e|
+for the
+.IR egrep (1)
+.LR ( ,
+.LR ) ,
+.LR ? ,
+.L +
+and
+.LR | ,
+respectively.
+.PP
+.L reexec
+matches the null-terminated
+.I source
+string against the compiled regular expression
+.I re
+from a previous call to
+.LR recomp .
+If it matches,
+.L reexec
+returns a non-zero value.
+If
+.I flags
+is
+.L RE_MATCH
+then the array
+.I re\->match
+is filled with character pointers to the substrings of
+.I source
+that correspond to the
+parenthesized subexpressions of 
+.IR pattern :
+.I re\->match[i].sp
+points to the beginning and
+.I re\->match[i].ep
+points just beyond
+the end of substring
+.IR i .
+(Subexpression
+.I i
+begins at the
+.IR i th
+matched left parenthesis, counting from 1.)
+Pointers in
+.I re\->match[0]
+pick out the substring that corresponds to
+the entire regular expression.
+Unused elements of
+.I re\->match
+are filled with zeros.
+Matches involving
+.LR * ,
+.LR + ,
+and 
+.L ?
+are extended as far as possible.
+A maximum of 9 subexpressions will be matched.
+The structure of elements of

+.LP
+.L ressub
+places in the

+in
+.I source
+in the context of the last
+.L reexec
+performed on

+are replaced by
+.IR new .
+If
+.L RE_LOWER
+.RL [ RE_UPPER ]
+is set in

+is converted to lower [upper] case.
+.LP
+.L reerror,
+called whenever an error is detected in
+.L recomp,
+.L reexec,

+.SH DESCRIPTION
+.PP
+I/O disciplines are used to extend the data processing power of
+\fIsfio\fP streams. The convention for using the disciplines
+in this package is to use the call \f5dcnewXXX()\fP to create
+a discipline of the type \f5XXX\fP and to use \f5dcdelXXX()\fP
+to destroy it.
+A discipline is enable by inserting it into the desired
+stream using the \f5sfdisc()\fP call. A discipline can be used on only
+one stream. It is unsafe to share a discipline on two or more streams
+since the discipline may maintain states between successive IO calls.
+For multiple uses, \f5dcnewXXX()\fP should be used
+to create a distinct discipline for each stream.
+Each discipline structure is equipped with an exception handler
+that causes self-destruction when the associated stream is closed.
+.PP
+.Ss "  Sfdisc_t* dcnewskable(Sfio_t* f);"
+.Ss "  int dcdelskable(Sfdisc_t* disc);"
+\f5dcnewskable()\fP creates a discipline that when inserted
+on the stream \f5f\fP will ensure that \f5f\fP is seekable.
+If \f5f\fP is originally unseekable, data will be shadowed
+in a temporary file stream to allow seekability.
+\f5dcnewskable()\fP returns the discipline on success and \f5NULL\fP on failure.
+
+.Ss "  Sfdisc_t* dcnewtee(Sfio_t* tee);"
+.Ss "  int dcdeltee(Sfdisc_t* disc);"
+\f5dcnewtee()\fP creates a discipline that
+when inserted into a stream \f5f\fP will duplicate to the stream \f5tee\fP
+any data written to \f5f\fP.
+\f5dcnewtee()\fP returns the discipline on success and \f5NULL\fP on failure.
+
+.Ss "  Sfdisc_t* dcnewfilter(char* cmd);"
+.Ss "  int dcdelfilter(Sfdisc_t* disc);"
+\f5dcnewfilter()\fP creates a discipline that
+when inserted into a stream \f5f\fP will run the command \f5cmd\fP
+to process any input data before making it available to the application.
+For example, \f5dcnewfilter("uncompress")\fP is an equivalent but slower
+alternative to the lzw discipline below.
+\f5dcnewfilter()\fP returns the discipline on success and \f5NULL\fP on failure.
+
+.Ss "  Sfdisc_t* dcnewsubstream(Sfio_t* base, long offset, long extent);"
+.Ss "  int dcdelsubstream(Sfdisc_t* disc);"
+\f5dcnewsubstream()\fP creates a discipline that
+reserves a portion of the stream \f5base\fP starting at \f5offset\fP
+with length \f5extent\fP and makes this portion appear as if it is
+a stream. When this discipline is inserted into a stream, it will make
+cause all IO operations on this stream to take place in the reserved
+portion of the \f5base\fP stream.
+\f5dcnewsubstream()\fP returns the discipline on success and \f5NULL\fP on failure.
+
+.Ss "  Sfdisc_t* dcnewlzw(void);
+.Ss "  int dcdellzw(Sfdisc_t* disc);"
+\f5dcnewlzw()\fP creates a discipline that when inserted into
+a stream \f5f\fP will run the \fBuncompress\fP algorithm
+on input data from \f5f\fP before making it available to the
+application. This is useful to allow applications to process
+data from a file packed with the UNIX \fBcompress\fP utility
+as if the data is in plain text.
+\f5dcnewlzw()\fP returns the discipline on success and \f5NULL\fP on failure.
+
+.Ss "  Sfdisc_t* dcnewunion(Sfio_t** list, int n);
+.Ss "  int dcdelunion(Sfdisc_t* disc);"
+\f5dcnewunion()\fP creates a discipline that concatenates
+input data from all \f5n\fP streams in \f5list\fP.
+When inserted into a stream \f5f\fP, this discipline will cause
+all input operations on \f5f\fP to come from the merged data stream.
+\f5dcnewunion()\fP returns the discipline on success and \f5NULL\fP on failure.
+
+.SH ACKNOWLEDGEMENTS
+Dave Korn contributed the substream discipline.
+Jim Arnold contributed the lzw discipline.
+
+.SH NOTES
+Since we are not sure of the legal responsibilities concerning the lzw patent,
+the lzw discipline is not currently distributed with any release of sfio
+outside of AT&T.

+.SH DESCRIPTION
+.PP
+Sfio provides I/O functions to manage buffered streams.
+Each Sfio stream is a \fIfile stream\fP, representing a file (see \f5open(2)\fP),
+or a \fIstring stream\fP, representing a memory segment.
+Beyond the usual I/O operations on streams,
+Sfio provides I/O disciplines for extended data processing,
+stream stacks for recursive stream processing, and
+stream pools for automatic data synchronization.
+Applications can extend the \f5sfprintf()/sfscanf()\fP functions
+to define their own conversion patterns as well as redefine existing ones.
+.PP
+A discipline defines analogues of 
+the system calls \f5read(2), write(2)\fP and \f5lseek(2)\fP.
+Such system calls or their discipline replacements are used to process stream data.
+Henceforth, ``\fIsystem call\fP'' will refer to either a system call
+or its discipline replacement.
+.PP
+A system call is said to cause an exception if its return value is non-positive.
+Unless overridden by exception handlers (see \f5sfdisc()\fP),
+an interrupted system call (\f5errno == EINTR\fP on UNIX systems)
+will be automatically reinvoked to continue the ongoing operation.
+.PP
+The buffer of a stream is typically a memory segment allocated via \f5malloc(3)\fP
+or supplied by the application.
+File streams may also use memory mapping (\f5mmap(2)\fP) if that is more efficient.
+When memory mapping is used,
+the underlying file should not be truncated while the stream is active.
+Memory mapping can be turned off using \f5sfsetbuf()\fP.
+.PP
+There are three \fIstandard streams\fP:
+\f5sfstdin\fP for input (file descriptor \f50\fP on UNIX systems),
+\f5sfstdout\fP for normal output (file descriptor \f51\fP), and
+\f5sfstderr\fP for error output (file descriptor \f52\fP).
+
+.PP
+.Ss "LIBRARIES"
+.PP
+This version of Sfio can be built and used for both uni-threaded and multi-threaded
+environments. In the former case, streams are not protected from
+simultaneous accesses by different threads. In the latter case, a stream
+is typically locked with a mutex during access so that another thread
+trying to access the same stream will block until the mutex is released.
+
+A program that does not use multiple threads can link with \fBlibsfio.a\fP
+while a program that uses multiple threads should link with \fBlibsfio-mt.a\fP.
+The libraries \fBlibstdio.a\fP and \fBlibstdio-mt.a\fP provide
+corresponding Stdio functions to link with code already compiled using the
+native header \fBstdio.h\fP instead of the one provided by Sfio.
+
+.PP
+.Ss "DATA TYPES"
+.PP
+.Ss "  Void_t*"
+This defines a type suitable to exchange
+data of unknown types between application and Sfio.
+\f5Void_t\fP is a macro defined as \f5void\fP for ANSI-C and C++ and
+\f5char\fP for other compilation environments.
+.PP
+.Ss "  Sfoff_t"
+This defines an integral type suitable to address
+the largest possible file extent.
+.PP
+.Ss "  Sfulong_t, Sflong_t, Sfdouble_t"
+These are respectively the largest
+unsigned integer, signed integer, and floating point value types on the local platform.
+.PP
+.Ss "  Sfio_t"
+This defines the type of a stream handle.
+.PP
+.Ss "  Sfdisc_t"
+.Ss "  ssize_t (*Sfread_f)(Sfio_t*, Void_t*, size_t, Sfdisc_t*)"
+.Ss "  ssize_t (*Sfwrite_f)(Sfio_t*, const Void_t*, size_t, Sfdisc_t*)"
+.Ss "  Sfoff_t (*Sfseek_f)(Sfio_t*, Sfoff_t, int, Sfdisc_t*)"
+.Ss "  int (*Sfexcept_f)(Sfio_t*, int, Void_t*, Sfdisc_t*)"
+\f5Sfdisc_t\fP defines a stream discipline structure.
+\f5Sfread_f\fP, \f5Sfwrite_f\fP and \f5Sfseek_f\fP are the types
+of discipline functions to replace the system calls:
+\f5read(2)\fP, \f5write(2)\fP and \f5lseek(2)\fP.
+\f5Sfexcept_f\fP is the type of an event-handling function.
+See \f5sfdisc()\fP for more details.
+.PP
+.Ss "  Sffmt_t"
+.Ss "  int (*Sffmtext_f)(Sfio_t*, Void_t*, Sffmt_t*)"
+.Ss "  int (*Sffmtevent_f)(Sfio_t*, int, Void_t*, Sffmt_t*)"
+\f5Sffmt_t\fP defines a formatting environment that can be used
+to extend scanning and printing in the \f5sfprint()/sfscanf()\fP
+functions. \f5Sffmtext_f\fP and \f5Sffmtevent_f\fP define the types
+of extension functions definable in \f5Sffmt_t\fP.
+See \f5Sffmt_t\fP below for more details.
+.PP
+.Ss "  SFIO_VERSION"
+This is a macro value of type \f5long int\fP that defines
+the current version number of Sfio. For example, the Sfio2000's
+version number is \f520000515L\fP
+(which also indicates its latest version date: 05/15/2000).
+
+.Ss "BIT FLAGS"
+A number of bit flags control stream operations.
+They are set either at stream initialization or by calling \f5sfset()\fP.
+Following are the flags:
+.Tp
+\f5SF_STRING\fP:
+The stream is memory-based.
+.Tp
+\f5SF_READ\fP, \f5SF_WRITE\fP, \f5SF_APPENDWR\fP (\f5SF_APPEND\fP):
+Flags \f5SF_READ\fP and \f5SF_WRITE\fP indicate readability and writability.
+Flag \f5SF_APPENDWR\fP asserts that the stream is a file opened in append mode
+(see \f5open(2)\fP and \f5fcntl(2)\fP)
+so that data is always output at the end of file.
+On systems without direct support for append mode,
+Sfio uses \f5lseek(2)\fP or its discipline replacement
+to approximate this behavior.
+.Tp
+\f5SF_LINE\fP:
+The stream is line-oriented.
+For a \f5SF_WRITE\fP stream,
+this means that buffered data is flushed
+whenever a new-line character, \f5\en\fP, is output.
+For a \f5SF_READ\fP stream, \f5SF_LINE\fP is only
+significant during calls to functions in the \f5sfscanf()\fP family.
+\f5SF_LINE\fP is set on initialization of
+any stream representing a terminal device.
+.Tp
+\f5SF_SHARE\fP, \f5SF_PUBLIC\fP:
+Flag \f5SF_SHARE\fP means that the underlying file descriptor
+is shared by independent entities (for example, multiple processes).
+
+For a seekable file stream, \f5SF_SHARE\fP means that
+the logical stream and the physical file positions will be made the same
+before a system call to perform physical I/O.
+There are different possibilities.
+If \f5SF_PUBLIC\fP is not set,
+the physical file position is made equal to the logical stream position.
+If \f5SF_PUBLIC\fP is set, there are two cases.
+If the physical file position has changed from its last known position,
+the logical stream position is made equal to the new physical file position.
+Finally, if the physical file location remains the same as its last known position,
+the physical file position is made the same as the logical stream position.
+
+For an unseekable stream (e.g., pipes or terminal devices), if possible,
+\f5SF_SHARE\fP means that
+the block and record I/O operations (\f5sfread()\fP, \f5sfwrite()\fP, \f5sfmove()\fP,
+\f5sfgetr()\fP, \f5sfputr()\fP, \f5sfreserve()\fP, \f5sfscanf()\fP
+and \f5sfvprintf()\fP) will ensure:
+(1) after each writing operation, the stream is synchronized and
+(2) each reading operation only reads the requested amount.
+Note, however, that (2) is not always possible
+without proper OS facilities such as \f5recv(2)\fP or \f5streamio(4)\fP.
+
+A standard stream that is seekable will be initialized with \f5SF_SHARE|SF_PUBLIC\fP.
+.Tp
+\f5SF_MALLOC\fP:
+The stream buffer was obtained via \f5malloc(3)\fP
+and can be reallocated or freed.
+.Tp
+\f5SF_STATIC\fP:
+The stream structure should not be freed when closed (\f5sfclose()\fP).
+This flag is used by an applications that allocate their own
+stream structures. Such applications must use the header file \f5sfio_t.h\fP
+instead of \f5sfio.h\fP.
+.Tp
+\f5SF_IOCHECK\fP:
+If the stream has a discipline exception handler,
+exceptions will be raised in \f5sfsync()\fP, \f5sfpurge()\fP
+or before a system call \f5read(2)\fP or \f5write(2)\fP (see \f5sfdisc()\fP).
+.Tp
+\f5SF_WHOLE\fP:
+This flag guarantees that data written in any single \f5sfwrite()\fP or
+\f5sfputr()\fP call will always be output as a whole to the output device.
+This is useful in certain applications (e.g., networking) where a complex object
+must be output without being split in different system calls.
+Note that the respective stream still buffers data as much as the buffer can accomodate.
+.Tp
+\f5SF_MTSAFE\fP:
+This flag indicates that the respective stream may be accessed by more than one threads.
+A mutex lock will be used to ensure that only one thread at a time can access
+the stream. Note that this flag can only be set at stream opening time
+(see \f5sfopen()\fP, \f5sfpopen()\fP and \f5sfnew()\fP).
+Certain fast macro functions such as \f5sfgetc()\fP and \f5sfputc()\fP will
+no longer behave as macros. Thus, an application that requires such fast macro functions
+should leave \f5SF_MTSAFE\fP off and performs explicit locking with \f5sfmutex()\fP.
+.Tp
+\f5SF_IOINTR\fP:
+This flag indicates that I/O system calls should not be resumed 
+after being interrupted by signals. It is useful for 
+aborting I/O operations on such interruptions. Note, however,
+than certain operating systems (e.g., BSD Unix systems) may automatically
+resume interrupted system calls outside the scope of the library. On such systems,
+\f5SF_IOINTR\fP will be ineffective.

+.Ss "OPENING/CLOSING STREAMS"
+.PP
+.Ss "  Sfio_t* sfnew(Sfio_t* f, Void_t* buf, size_t size, int fd, int flags)"
+This function creates or renews a stream.
+It returns the new stream on success and \f5NULL\fP on error.
+.Tp
+\f5f\fP:
+If \f5f\fP is \f5NULL\fP, a new stream is created.
+Otherwise, \f5f\fP is reused.
+In this case, if \f5flags\fP does not have \f5SF_EOF\fP,
+\f5f\fP shall be closed via \f5sfclose()\fP before being reused.
+During a stream renewal, buffer, pool and discipline stack are preserved.
+Note that, except for \f5SF_STATIC\fP streams,
+renewing a stream already closed will result in undefined behavior.
+.Tp
+\f5buf\fP, \f5size\fP:
+These determine a buffering scheme.
+See \f5sfsetbuf()\fP for more details.
+.Tp
+\f5fd\fP:
+If \f5SF_STRING\fP is specified in \f5flags\fP, this is ignored.
+Otherwise, \f5fd\fP is a file descriptor (e.g., from \f5open(2)\fP)
+to use for raw data I/O.
+Note that Sfio supports unseekable file descriptors
+opened for both read and write, e.g., sockets.
+.Tp
+\f5flags\fP:
+This is composed from \f5SF_EOF\fP and
+bit values defined in the \fBBIT FLAGS\fP section.
+Note, in particular, that a multi-threaded application should
+set the bit \f5SF_MTSAFE\fP to protect the new stream from
+being simultaneously accessed by multiple threads.
+
+.Ss "  Sfio_t* sfopen(Sfio_t* f, const char* string, const char* mode)"
+
+If \f5string\fP is \f5NULL\fP,
+\f5f\fP is a file stream and
+\f5mode\fP does not imply a string stream,
+\f5sfopen()\fP changes the modes of \f5f\fP according to \f5mode\fP.
+In this case, \f5sfopen()\fP returns \f5f\fP on success and \f5NULL\fP on error.
+This somewhat unusual usage of \f5sfopen()\fP is good for
+resetting certain predefined modes in standard streams including
+\fItext/binary\fP and \fIappend\fP that are inherited from some parent process.
+Note also that \f5SF_READ\fP and \f5SF_WRITE\fP can only be reset if the stream
+is not yet initialized.
+
+\f5sfopen()\fP is normally used to create a new stream or renew a stream.
+In this case, it returns the new stream on success and \f5NULL\fP on error.
+Below are the meanings of the arguments:
+.Tp
+\f5f\fP:
+This is treated as in \f5sfnew()\fP.
+.Tp
+\f5string\fP:
+This is a file name or a string to perform I/O on.
+See above for when this is \f5NULL\fP.
+.Tp
+\f5mode\fP:
+This is composed from the set of letters \f5{s, r, w, +, a, b, t, x, m, u}\fP.
+When conflicting options are present in the same \f5mode\fP string,
+the last one will take effect.
+
+\f5s\fP specifies opening a string stream.
+\f5string\fP can be a null-terminated string or \f5NULL\fP.
+Specifying \f5s\fP alone is equivalent to specifying \f5sr\fP.
+If \f5s\fP is not specified, \f5string\fP defines a file name.
+
+\f5r\fP and \f5w\fP specify read and write modes.
+Write mode creates and/or truncates the given file to make an empty file.
+The \f5+\fP modifier indicates that the stream is opened for both read and write.
+
+\f5a\fP specifies append mode, i.e., data is always output at end of file.
+
+\f5b\fP and \f5t\fP specify binary and text modes.
+
+\f5x\fP specifies exclusive mode, i.e.,
+a file opened for writing should not already exist.
+
+\f5m\fP specifies that the stream needs to be protected from
+simultaneous accesses by multiple threads.
+This turns on the bit flag \f5SF_MTSAFE\fP.
+
+\f5u\fP specifies that the stream is guaranteed to be accessed
+by only one thread at a time. The bit flag \f5SF_MTSAFE\fP is left off.
+The absence of option \f5m\fP is the same as the presence of option \f5u\fP.
+
+.Ss "  Sfio_t* sfpopen(Sfio_t* f, const char* cmd, const char* mode)"
+This function opens a stream that corresponds to the coprocess \f5cmd\fP.
+The argument \f5mode\fP should be composed from \f5r\fP, \f5w\fP, and \f5+\fP.
+The argument \f5f\fP, if not \f5NULL\fP, is a stream to be renewed (see \f5sfnew()\fP).
+\f5sfpopen()\fP returns the new stream or \f5NULL\fP on error.
+
+The standard input/output of \f5cmd\fP
+is connected to the application via a pipe if the stream is opened for writing/reading.
+If the stream is opened for both reading and writing,
+there will be two different associated file descriptors, one for each type of I/O
+(note the effect on \f5sffileno()\fP).
+
+On opening a coprocess for writing (i.e., \f5mode\fP contains \f5w\fP or \f5+\fP),
+the signal handler for \f5SIGPIPE\fP in the parent application
+will be set to \f5SIG_IGN\fP if it is \f5SIG_DFL\fP at that time.
+This protects the parent application from being accidentally killed
+on writing to a coprocess that closes its reading end.
+Applications that need to detect such write errors should use
+disciplines and exception handlers (see \f5sfdisc()\fP).
+
+The command \f5cmd\fP
+is executed by an \fIinterpreter\fP which is either \f5/bin/sh\fP
+or an executable command defined by the environment variable \f5SHELL\fP.
+In either case, the interpreter is invoked with 2 arguments, respectively \f5-c\fP
+and the given command \f5cmd\fP. When the interpreter is \f5/bin/sh\fP or
+\f5/bin/ksh\fP, \f5sfpopen()\fP may execute the command \f5cmd\fP itself
+if there are no shell meta-characters in \f5cmd\fP.
+
+.Ss "  Sfio_t* sftmp(size_t size)"
+This function creates a stream for temporary data.
+It returns the new stream or \f5NULL\fP on error.
+
+A stream created by \f5sftmp()\fP can be completely or partially memory-resident.
+If \f5size\fP is \f5SF_UNBOUND\fP, the stream is a pure string stream.
+If \f5size\fP is zero, the stream is a pure file stream.
+Otherwise, the stream is first created as a string stream but when
+its buffer grows larger than \f5size\fP or on any attempt to change disciplines,
+a temporary file is created.
+Two environment variables, \f5TMPPATH\fP and \f5TMPDIR\fP,
+direct where temporary files are created.
+\f5TMPPATH\fP, if defined,
+specifies a colon-separated set of directories to be
+used in a round-robin fashion to create files.
+If \f5TMPPATH\fP is undefined,
+\f5TMPDIR\fP can be used to specify a single directory to create files.
+If neither of \f5TMPPATH\fP and \f5TMPDIR\fP are defined, \f5/tmp\fP is used.
+
+.Ss "  int sfclose(Sfio_t* f)"
+This function closes the stream \f5f\fP and frees its resources.
+\f5SF_STATIC\fP should be used if the stream space is to be preserved.
+If \f5f\fP is the base of a stream stack (see \f5sfstack()\fP),
+all streams on the stack are closed.
+If \f5f\fP is a \f5sfpopen\fP-stream,
+\f5sfclose()\fP waits until the associated command terminates
+and returns its exit status.
+\f5sfclose()\fP returns \f5-1\fP for failure and \f50\fP for success.
+
+\f5SF_READ|SF_SHARE\fP and \f5SF_WRITE\fP streams
+are synchronized before closing (see \f5sfsync()\fP).
+If \f5f\fP has disciplines,
+their exception handlers will be called twice.
+The first exception handler call has the \f5type\fP argument as one of
+\f5SF_CLOSING\fP or \f5SF_NEW\fP (see \f5sfdisc()\fP.)
+The latter, \f5SF_NEW\fP is used when a stream is being closed via \f5sfnew()\fP
+so that it can be renewed.
+The second call uses \f5type\fP as \f5SF_FINAL\fP
+and is done after all closing operations have succeeded but before
+the stream itself is deallocated.
+In either case, if the exception handler returns a negative value,
+\f5sfclose()\fP will immediately return this value.
+If the exception handler returns a positive value,
+\f5sfclose()\fP will immediately return a zero value.
+
+.PP
+.Ss "THREAD SAFETY"
+.PP
+The libraries \f5libsfio.a\fP and \f5libstdio.a\fP (providing binary
+compatibility to Stdio-based code) only support uni-threaded code.
+Multi-threaded applications should link with
+\f5libsfio-mt.a\fP and \f5libstdio-mt.a\fP.
+When this is done, certain platforms may require additional
+thread libraries for linkage. For example, Linux, Irix and Solaris
+require \f5-lpthread\fP while HPUX requires \f5-lcma\fP.
+Aside from linkage differences, the Sfio API remains identical in all cases.
+
+Note that unlike Stdio streams which are in thread-safe mode by default.
+Sfio streams can be opened in either uni-threaded or multi-threaded mode.
+A uni-threaded stream is more efficient than a multi-threaded one.
+For example, functions such as \f5sfgetc()\fP and \f5sfputc()\fP
+remain as macro or inline functions for a uni-threaded stream while
+they will act as full function calls in a multi-threaded case.
+The three standard streams \f5sfstdin/sfstdout/sfstderr\fP
+are in multi-threaded mode by default
+(however, see \f5sfopen()\fP for how this may be changed).
+Other Sfio streams are normally opened uni-threaded unless
+the flag \f5SF_MTSAFE\fP or the option \f5m\fP were specified.
+Stdio-based code can also make a Stdio stream uni-threaded by
+using the option \f5u\fP when opening a file.
+
+.PP
+.Ss "int sfmutex(Sfio_t* f, int type)"
+This function acquires or releases a mutex
+(mutually exclusive) lock on the stream \f5f\fP.
+It can be used by a thread to delineate  a sequence of I/O operations
+executed together in some critical section.
+\f5sfmutex()\fP is implicitly used by
+all Sfio operations on a stream with the flag \f5SF_MTSAFE\fP.
+\f5sfmutex()\fP returns \f50\fP on success and some non-zero value on failure.
+
+Each stream has a lock count which starts at \f50\fP.
+When the count is positive, a single thread holds the stream.
+Only this thread can further lock or unlock the stream.
+A different thread attempting to acquire such a locked stream will suspend
+until the lock count returns to \f50\fP.
+Each successful locking operation increases the lock count
+while each successful unlocking operation decreases it,
+thus, allowing nesting of matching lock/unlock operations.
+
+The \f5type\fP argument of \f5sfmutex()\fP takes on the below values:
+.Tp
+\f5SFMTX_LOCK\fP:
+Locking a stream if it is unlocked or increasing the lock count of the stream
+if it is already locked by the same thread.
+.Tp
+\f5SFMTX_TRYLOCK\fP:
+This is the non-blocking version of \f5SFMTX_LOCK\fP.
+If the stream is already locked by a different thread, \f5sfmutex()\fP will
+immediately return with an error status.
+.Tp
+\f5SFMTX_UNLOCK\fP:
+Decreasing the lock count and releasing the stream when the lock count reaches 0.
+An attempt to unlock a stream without a previously successful lock may
+result in undefined behavior in certain implementations.
+The current Sfio implementation returns an error status.
+.Tp
+\f5SFMTX_CLRLOCK\fP:
+Resetting the lock count to \f50\fP and releasing the stream.
+As with \f5SFMTX_LOCK\fP,
+an attempt to clear the lock count without a previously successful lock
+may result in undefined behavior.
+.PP

+.PP
+.Ss "  int sfgetc(Sfio_t* f)"
+.Ss "  int sfputc(Sfio_t* f, int c)"
+These functions read/write a byte  from/to stream \f5f\fP.
+\f5sfgetc()\fP returns the byte read or \f5-1\fP on error.
+\f5sfputc()\fP returns \f5c\fP on success and \f5-1\fP on error.
+
+.Ss "  ssize_t sfnputc(Sfio_t* f, int c, size_t n)"
+This function attempts to write the byte \f5c\fP to \f5f\fP \f5n\fP times.
+It returns the number of bytes actually written or \f5-1\fP on failure.
+
+.Ss "  int sfungetc(Sfio_t* f, int c)"
+This function pushes the byte \f5c\fP back into \f5f\fP.
+If \f5c\fP matches the byte immediately before the current position in buffered data,
+the current position is simply backed up (note the effect on \f5sftell()\fP and
+\f5sfseek()\fP). There is no theoretical limit on the number of bytes that
+can be pushed back into a stream. Pushed back bytes not part of
+buffered data will be discarded on any operation that implies
+buffer synchronization.
+\f5sfungetc()\fP returns \f5c\fP on success and \f5-1\fP on failure.
+
+.Ss "  Sfulong_t sfgetm(Sfio_t* f, Sfulong_t max)"
+.Ss "  int sfputm(Sfio_t* f, Sfulong_t v, Sfulong_t max)"
+These functions read and write \f5Sfulong_t\fP values
+encoded in a portable format given that the values are at most \f5max\fP.
+Portability across a write architecture and a read architecture
+requires that the bit order in a byte is the same on both architectures and
+the written value is storable in an \f5Sfulong_t\fP on the read architecture.
+\f5sfgetm()\fP returns the value read or \f5-1\fP on error.
+\f5sfputm()\fP returns the number of bytes written or \f5-1\fP on error.
+
+.Ss "  Sfulong_t sfgetu(Sfio_t* f)"
+.Ss "  int sfputu(Sfio_t* f, Sfulong_t v)"
+These functions read and write \f5Sfulong_t\fP values
+in a compact variable-length portable format.
+Portability across a write architecture and a read architecture
+requires that the bit order in a byte is the same on both architectures and
+the written value is storable in an \f5Sfulong_t\fP on the read architecture.
+\f5sfgetu()\fP returns the value read or \f5-1\fP on error.
+\f5sfputu()\fP returns the number of bytes written or \f5-1\fP on error.
+See also \f5sfulen()\fP.
+
+.Ss "  Sflong_t sfgetl(Sfio_t* f)"
+.Ss "  int sfputl(Sfio_t* f, Sflong_t v)"
+These functions are similar to \f5sfgetu()\fP and \f5sfputu()\fP
+but for reading and writing (signed) \f5Sflong_t\fP values.
+See also \f5sfllen()\fP.
+
+.Ss "  Sfdouble_t sfgetd(Sfio_t* f)"
+.Ss "  int sfputd(Sfio_t* f, Sfdouble_t v)"
+These functions read and write \f5Sfdouble_t\fP values.
+In this case, portability depends on the input and output architectures
+having the same floating point value representation.
+Values are coded and decoded using \f5ldexp(3)\fP and \f5frexp(3)\fP
+so they are constrained to the sizes supported by these functions.
+See also \f5sfdlen()\fP.
+
+.Ss "  char* sfgetr(Sfio_t* f, int rsc, int type)"
+This function reads a record of data ending in the record separator \f5rsc\fP.
+After \f5sfgetr()\fP returns, the length of the record even if it is incomplete
+can be retrieved with \f5sfvalue()\fP.
+\f5sfgetr()\fP returns the record on success and \f5NULL\fP on error.
+See also \f5sfmaxr()\fP for limiting the amount of data read to construct a record.
+
+The \f5type\fP argument is composed of some subset of the below bit flags:
+.Tp
+\f5SF_STRING\fP:
+A null byte will replace the record separator to make the record into a C string.
+Otherwise, the record separator is left alone.
+.Tp
+\f5SF_LOCKR\fP:
+Upon successfully obtaining a record \f5r\fP,
+the stream will be locked from further access until it is released with
+a call \f5sfread(f,r,0)\fP.
+.Tp
+\f5SF_LASTR\fP:
+This should be used only after a failed \f5sfgetr()\fP to retrieve
+the last incomplete record. In this case, \f5rsc\fP is ignored.
+
+.Ss "  ssize_t sfputr(Sfio_t* f, const char* s, int rsc)"
+This function writes the null-terminated string \f5s\fP to \f5f\fP.
+If \f5rsc\fP is non-negative, \f5(unsigned char)rsc\fP is output after the string.
+\f5sfputr()\fP returns the number of bytes written or \f5-1\fP on failure.
+
+.Ss "  Sfoff_t sfmove(Sfio_t* fr, Sfio_t* fw, Sfoff_t n, int rsc)"
+This function moves objects
+from input stream \f5fr\fP to output stream \f5fw\fP.
+\f5sfmove()\fP returns the number of objects moved or \f5-1\fP on failure.
+
+An object can be either a byte if the record separator argument
+\f5rsc\fP is negative or a record of \f5rsc\fP is non-negative.
+In the latter case, a record is incomplete if it does not end in \f5rsc\fP. 
+Generally speaking, a stream can have at most one incomplete record.
+If \f5n\fP is negative, all complete objects of \f5fr\fP will be moved.
+Otherwise, \f5n\fP indicates the number of objects to move.
+If either \f5fr\fP or \f5fw\fP is \f5NULL\fP, it acts
+as if it is a stream corresponding to \f5/dev/null\fP,
+the UNIX device that has no read data and throws away any write data.
+For example, the call \f5sfmove(f,(Sfio_t*)0,(Sfoff_t)(-1),'\en')\fP
+counts the number of complete lines in stream \f5f\fP.
+
+.Ss "  ssize_t sfread(Sfio_t* f, Void_t* buf, size_t n)"
+This function reads up to \f5n\fP bytes from \f5f\fP into buffer \f5buf\fP.
+It returns the number of bytes actually read or \f5-1\fP on error.
+
+.Ss "  ssize_t sfwrite(Sfio_t* f, const Void_t* buf, size_t n)"
+This function writes \f5n\fP bytes from \f5buf\fP to \f5f\fP.
+If \f5f\fP is \f5SF_STRING\fP, and the buffer is not large enough,
+an \f5SF_WRITE\fP exception shall be raised.
+\f5sfwrite()\fP returns the number of bytes written or \f5-1\fP on failure.
+
+.Ss "  Sfoff_t sfseek(Sfio_t* f, Sfoff_t offset, int type)"
+This function sets a new I/O position for \f5f\fP.
+It returns the new position or \f5-1\fP on failure.
+
+If the stream is a \f5SF_STRING\fP stream and the new
+address is beyond the current buffer extent,
+an \f5SF_SEEK\fP exception will be raised (see \f5sfdisc()\fP).
+
+The new position is determined based on \f5offset\fP and
+\f5type\fP which is composed from the bit flags:
+.Tp
+\f50\fP or \f5SEEK_SET\fP:
+\f5offset\fP is the desired position.
+.Tp
+\f51\fP or \f5SEEK_CUR\fP:
+\f5offset\fP is relative to the current position (see \f5SF_PUBLIC\fP below).
+.Tp
+\f52\fP or \f5SEEK_END\fP:
+\f5offset\fP is relative to the physical end of file.
+.Tp
+\f5SF_SHARE\fP:
+The stream is treated as if it has the control bit \f5SF_SHARE\fP on.
+This implies that a system call seek will be done to ensure that the
+location seeking to is valid.
+.Tp
+\f5SF_PUBLIC\fP:
+The stream is treated as if it has the control bit \f5SF_PUBLIC\fP on.
+If the physical file position has changed from its last known location,
+the current position is taken as the new physical position.
+Otherwise, the current position is the logical stream position.
+
+.Ss "  Void_t* sfreserve(Sfio_t* f, ssize_t n, int type)"
+This function reserves a data block from the stream \f5f\fP.
+It returns the reserved data block on success and \f5NULL\fP on failure.
+
+If \f5f\fP is a \f5SF_READ\fP stream, the data block is a segment of input data.
+If \f5f\fP is a \f5SF_WRITE\fP stream, the data block is a buffer
+suitable for writing output data.
+For consistency, if \f5f\fP is opened with \f5SF_READ|SF_WRITE\fP,
+it will normally be treated as if it is a \f5SF_READ\fP stream
+(see \f5sfset()\fP for forcing a particular mode) but the returned
+buffer can also be written into (more below).
+However, it is possible to bias to \f5SF_WRITE\fP when the \f5type\fP
+argument is non-negative by adding the \f5SF_WRITE\fP bit \f5type\fP.
+In any case, a reserved data block is guaranteed to be valid only until
+a future access to the stream \f5f\fP.
+
+When \f5f\fP is \f5SF_READ\fP, \f5SF_SHARE\fP and unseekable,
+\f5sfreserve()\fP will attempt to peek at input data without
+consuming it. This enables separate processes to share in reading
+input from unseekable file descriptors (e.g., pipes or devices).
+However, this use of \f5sfreserve()\fP may fail
+on certain platforms that do not properly support
+peeking on unseekable file descriptors.
+
+After a \f5sfreserve()\fP call, whether or not it succeeds,
+\f5sfvalue(f)\fP gives the size of the available data block.
+Any partially reserved data block after a failed \f5sfreserve()\fP
+call can be obtained in another \f5sfreserve()\fP call with the argument
+\f5type\fP being \f5SF_LASTR\fP. The second argument \f5n\fP
+to \f5sfreserve()\fP will be ignored in this case.
+
+A \f5sfreserve()\fP call is successful if it can obtain a data block 
+of size at least the absolute value of \f5n\fP.
+For a \f5SF_READ\fP atream, the argument \f5n\fP is treated as follows:
+.Tp
+\f5n < 0\fP:
+\f5sfreserve()\fP attempts to get \fIat least\fP \f5|n|\fP bytes
+into the buffer.
+.Tp
+\f5n == 0\fP:
+If the argument \f5type\fP is \f50\fP,
+\f5sfreserve()\fP attempts to get \fIat least\fP \f51\fP byte into the buffer;
+otherwise, no attempt will be made to read data into the buffer.
+For example, the call \f5sfreserve(f, 0, -1)\fP only returns the buffer status,
+i.e., size of existing buffered data and pointer to such data, if any.
+The call \f5sfreserve(f, 0, SF_LOCKR)\fP is similar but also locks the stream.
+.Tp
+\f5n > 0\fP:
+\f5sfreserve()\fP will use attempt to get \fIat most\fP \f5n\fP bytes into
+the buffer. Further, if \f5type == \f5SF_LOCKR\fP (see below), read attempts
+end on a positive amount.
+
+For a successful reservation, the argument \f5type\fP dictates treatment
+as follows:
+.Tp
+\f5type == SF_LASTR\fP:
+After a \f5sfreserve()\fP call with \f5type != SF_LOCKR\fP fails,
+there may be some left over data not accessible via conventional Sfio calls.
+Immediately after such a failed call,
+another call to \f5sfreserve\fP with \f5type == SF_LASTR\fP will return any left over
+data and also advance the stream I/O position by the amount of returned data.
+.Tp
+\f5type < 0\fP:
+If \f5n > 0\fP, the stream I/O position is advanced by \f5n\fP.
+If \f5n < 0\fP, the stream I/O position is advanced by the amount
+of available data.
+For example, a successful \f5sfreserve(f, -1, -1)\fP call will return a
+buffer of data and simultanously advance the stream I/O position by the amount

+\f5type == SF_LOCKR\fP:
+The stream I/O position remains unchanged.
+In addition, \f5f\fP will be locked from further access.
+As appropriate to the stream type (\f5SF_READ\fP, \f5SF_WRITE\fP or both),
+\f5f\fP can be unlocked later
+with one of \f5sfread(f,rsrv,size)\fP or \f5sfwrite(f,rsrv,size)\fP
+where \f5rsrv\fP is the reserved data block and \f5size\fP is the amount of
+data to be consumed. For example, if \f5f\fP is a locked \f5SF_READ\fP stream,
+the call \f5sfread(f,rsrv,1)\fP will reopen the stream and simultaneously
+advance the stream I/O position by \f51\fP.
+Finally, a stream opened for both reading and writing
+can release the lock with either call (with associated operational semantics!)
+For example, the below code reads 10 bytes of data from a stream
+opened with both \f5SF_READ\fP and \f5SF_WRITE\fP, modifies the data in place,
+then rewrites the new data back to the stream:

+.PP
+.Ss "DATA FORMATTING"
+.PP
+Data printing and scanning are done via the
+\f5sfprintf()\fP and \f5sfscanf()\fP family of functions.
+These functions are similar to their
+ANSI-C \f5fprintf()\fP and \f5fscanf()\fP counterparts.
+However, the Sfio versions have been extended for both portability and generality.
+In particular, a notion of a formatting environment stack is introduced.
+Each formatting element on the stack
+defines a separate \fIformatting pair\fP of a format specification string,
+\f5char* format\fP (the usual second argument in the formatting
+functions), and an argument list, \f5va_list args\fP (the third argument
+in functions \f5sfvprintf()\fP and \f5sfvscanf()\fP).
+A formatting environment element may also specify extension functions
+to obtain or assign arguments and to provide new semantics for pattern processing.
+To simplify the description below, whenever we talk
+about an argument list, unless noted otherwise,
+it is understood that this means either the true
+argument list when there is no extension function or the action to be taken
+by such a function in processing arguments.
+The manipulation of the formatting environment stack is done
+via the pattern \f5!\fP discussed below.
+
+.Ss "%! and Sffmt_t"
+The pattern \f5%!\fP manipulates the formatting environment stack to
+(1) change the top environment to a new environment,
+(2) stack a new environment on top of the current top,
+or (3) pop the top environment.
+The bottom of the environment stack always contains a virtual environment with the
+original formatting pair and without any extension functions.
+
+The top environment of a stack, say \f5fe\fP, is automatically popped whenever
+its format string is completely processed.
+In this case, its event-handling function (if any) is called
+as \f5(*eventf)(f,SF_FINAL,NIL(Void_t*),fe)\fP.
+The top environment
+can also be popped by giving an argument \f5NULL\fP to \f5%!\fP
+or by returning a negative value in an extension function.
+In these cases, the event-handling function is called
+as \f5(*eventf)(f,SF_DPOP,form,fe)\fP where \f5form\fP is the remainder
+of the format string. A negative return value from the event handling function
+will prevent the environment from being popped.
+
+A formatting environment is a structure of type \f5Sffmt_t\fP
+which contains the following elements:
+
+.nf
+.ft 5
+    Sffmtext_f   extf;   /* extension processor        */
+    Sffmtevent_f eventf; /* event handler              */
+
+    char*        form;   /* format string to stack     */
+    va_list      args;   /* corresponding arg list     */
+        
+    int          fmt;    /* pattern being processed    */
+    ssize_t      size;   /* object size                */
+    int          flags;  /* formatting control flags   */
+    int          width;  /* width of field             */
+    int          precis; /* precision required         */
+    int          base;   /* conversion base            */
+
+    char*        t_str;  /* extfdata string            */
+    int          n_str;  /* length of t_str            */
+.ft 1
+.fi
+
+The first four elements of \f5Sffmt_t\fP must be defined by the application
+before the structure is passed to a formatting function.
+The two function fields should not be changed during processing.
+Other elements of \f5Sffmt_t\fP are set by the respective formatting function
+before it calls the extension function \f5Sffmt_t.extf\fP and, subsequently,
+can be modified by this function to redirect formatting or scanning.
+For example, consider a call from a \f5sfprintf()\fP function to process an
+unknown pattern \f5%t\fP (which we may take to mean ``time'') based on a
+formatting environment \f5fe\fP.
+\f5fe->extf\fP may reset \f5fe->fmt\fP to `\f5d\fP' upon returing
+to cause \f5sfprintf()\fP to process the value being formatted as an integer.
+
+Below are the fields of \f5Sffmt_t\fP:
+.Tp
+\f5extf\fP:
+\f5extf\fP is a function to extend scanning and formatting patterns.
+Its usage is discussed below.
+.Tp
+\f5eventf\fP:
+This is a function to process events as discussed earlier.
+.Tp
+\f5form\fP and \f5args\fP:
+This is the formatting pair of a specification string and corresponding argument list.
+When an environment \f5fe\fP is being inserted into the stack,
+if \f5fe->form\fP is \f5NULL\fP, the top environment is changed to \f5fe\fP
+and its associated extension functions
+but processing of the current formatting pair continues.
+On the other hand, if \f5fe->form\fP is not \f5NULL\fP,
+the new environment is pushed onto the stack
+so that pattern processing will start with the new formatting pair as well as
+any associated extension functions.
+During processing, whenever \f5extf\fP is called,
+\f5form\fP and \f5args\fP will be set to the current values of
+the formatting pair in use.
+.Tp
+\f5fmt\fP:
+This is set to the pattern being processed or one of '.', 'I', '('.
+.Tp
+\f5size\fP:
+This is the size of the object being processed.
+.Tp
+\f5flags\fP:
+This is a collection of bits defining the formatting flags specified for the pattern.
+The bits are:
+
+\f5SFFMT_LEFT\fP: Flag \f5-\fP in \f5sfprintf()\fP.
+
+\f5SFFMT_SIGN\fP: Flag \f5+\fP in \f5sfprintf()\fP.
+
+\f5SFFMT_BLANK\fP: Flag \fIspace\fP in \f5sfprintf()\fP.
+
+\f5SFFMT_ZERO\fP: Flag \f50\fP in \f5sfprintf()\fP.
+
+\f5SFFMT_THOUSAND\fP: Flag \f5'\fP in \f5sfprintf()\fP.
+
+\f5SFFMT_LONG\fP: Flag \f5l\fP in \f5sfprintf()\fP and \f5sfscanf()\fP.
+
+\f5SFFMT_LLONG\fP: Flag \f5ll\fP in \f5sfprintf()\fP and \f5sfscanf()\fP.
+
+\f5SFFMT_SHORT\fP: Flag \f5h\fP in \f5sfprintf()\fP and \f5sfscanf()\fP.
+
+\f5SFFMT_LDOUBLE\fP: Flag \f5L\fP in \f5sfprintf()\fP and \f5sfscanf()\fP.
+
+\f5SFFMT_IFLAG\fP: flag \f5I\fP in \f5sfprintf()\fP and \f5sfscanf()\fP.
+
+\f5SFFMT_ALTER\fP: Flag \f5#\fP in \f5sfprintf()\fP and \f5sfscanf()\fP.
+
+\f5SFFMT_SKIP\fP: Flag \f5*\fP in \f5sfscanf()\fP.
+
+\f5SFFMT_ARGPOS\fP: This indicates argument processing for \f5pos$\fP.
+
+\f5SFFMT_VALUE\fP: This is set by \f5fe->extf\fP
+to indicate that it is returning a value to be formatted or
+the address of an object to be assigned.
+
+.Tp
+\f5width\fP:
+This is the field width.
+.Tp
+\f5precis\fP:
+This is the precision.
+.Tp
+\f5base\fP:
+This is the conversion base.
+.Tp
+\f5t_str\fP and \f5n_str\fP:
+This is the type string and its size.
+
+.Ss "  int (*Sffmtext_f)(Sfio_t* f, Void_t* v, Sffmt_t* fe)"
+This is the type of the extension function \f5fe->extf\fP to process
+patterns and arguments.
+Arguments are always processed in order and
+\f5fe->extf\fP is called exactly once per argument.
+Note that, when \f5pos$\fP (below) is not used anywhere in a format string,
+each argument is used exactly once per a corresponding pattern.
+In that case, \f5fe->extf\fP is called 
+as soon as the pattern is recognized and before any scanning or formatting.
+On the other hand, when \f5pos$\fP is used in a format string,
+an argument may be used multiple times.
+In this case, all arguments shall be processed in order
+by calling \f5fe->extf\fP exactly once per argument before any pattern processing.
+This case is signified by the flag \f5SFFMT_ARGPOS\fP in \f5fe->flags\fP.
+
+In addition to the predefined formatting patterns and other application-defined
+patterns, \f5fe->extf\fP may be called with \f5fe->fmt\fP being one
+of `\f5(\fP' (left parenthesis), `\f5.\fP' (dot), and `\f5I\fP'.
+
+The left parenthesis requests a string to be used as the \f5extfdata\fP string discussed below.
+In this case, upon returning, \f5fe->extf\fP should set the \f5fe->size\fP field
+to be the length of the string or a negative value to indicate a null-terminated string.
+
+The `\f5I\fP' requests an integer to define the object size.
+
+The dot requests an integer for width, precision, base, or a separator.
+In this case, the \f5fe->size\fP field will indicate how many dots have appeared
+in the pattern specification. Note that, if the actual conversion pattern is 'c' or 's',
+the value \f5*form\fP will be one of these characters.
+.Tp
+\f5f\fP:
+This is the input/output stream in the calling formatting function.
+During a call to \f5fe->extf\fP, the stream shall be unlocked
+so that \f5fe->extf\fP can read from or write to it as appropriate.
+.Tp
+\f5v\fP:
+For both \f5sfscanf()\fP and \f5sfprintf()\fP functions,
+\f5v\fP points to a location suitable for storing any scalars or pointers.
+On return, \f5fe->extf\fP treats \f5v\fP as discussed below.
+.Tp
+\f5fe\fP:
+This is the current formatting environment.
+.PP
+The return value \f5rv\fP of \f5fe->extf\fP directs further processing.
+There are two cases.
+When \f5pos$\fP is present, a negative return value means to ignore \f5fe\fP
+in further argument processing while a non-negative return value is treated
+as the case \f5rv == 0\fP below.
+When \f5pos$\fP is not present, \f5fe->extf\fP is called per argument
+immediately before pattern processing and its return values are treated
+as below:
+.Tp
+\f5rv < 0:\fP
+The environment stack is immediately popped.
+.Tp
+\f5rv == 0:\fP
+The extension function has not consumed (in a scanning case) or
+output (in a printing case) data out of or into the given stream \f5f\fP.
+The fields \f5fmt\fP, \f5flags\fP, \f5size\fP,
+\f5width\fP, \f5precis\fP and \f5base\fP of \f5fe\fP
+shall direct further processing.
+
+For \f5sfprintf()\fP functions, if \f5fe->flags\fP
+has the bit \f5SFFMT_VALUE\fP,
+\f5fe->extf\fP should have set \f5*v\fP to the value to be processed;
+otherwise, a value should be obtained from the argument list.
+Likewise, for \f5sfscanf()\fP functions,
+\f5SFFMT_VALUE\fP means that
+\f5*v\fP should have a suitable address; otherwise,
+an address to assign value should be obtained from the argument list.
+
+When \f5pos$\fP is present,
+if \f5fe->extf\fP changes \f5fe->fmt\fP, this pattern shall be used regardless of
+the pattern defined in the format string. On the other hand, if \f5fe->fmt\fP
+is unchanged by \f5fe->extf\fP, the pattern in the format string is used.
+In any case, the effective pattern should be one of the standardly defined pattern.
+Otherwise, it shall be treated as unmatched.
+.Tp
+\f5rv > 0:\fP
+The extension function has accessed the stream \f5f\fP
+to the extent of \f5rv\fP bytes.
+Processing of the current pattern ceases except that,
+for scanning functions, if \f5fe->flags\fP does not contain
+the bit \f5SFFMT_SKIP\fP, the assignment count shall increase by 1.
+
+.Ss "void va_copy(va_list to, va_list fr)"
+This macro function portably copies the argument list \f5fr\fP to
+the argument list \f5to\fP. It should be used to set the field \f5Sffmt_t.args\fP.
+
+.Ss "long sffmtversion(Sffmt_t* fe, int type)"
+This macro function initializes
+the formatting environment \f5fe\fP with a version number if \f5type\fP is
+non-zero. Otherwise, it returns the current value of the version number of \f5fe\fP.
+This is useful for applications to find out
+when the format of the structure \f5Sffmt_t\fP changes.
+Note that the version number corresponds to the Sfio version number
+which is defined in the macro value \f5SFIO_VERSION\fP.
+
+.Ss "  int sfprintf(Sfio_t* f, const char* format, ...);"
+.Ss "  char* sfprints(const char* format, ...);"
+.Ss "  char* sfvprints(const char* format, va_list args);"
+.Ss "  ssize_t sfaprints(char** sp, const char* format, ...);"
+.Ss "  ssize_t sfvaprints(char** sp, const char* format, va_list args);"
+.Ss "  int sfsprintf(char* s, int n, const char* format, ...)"
+.Ss "  int sfvsprintf(char* s, int n, const char* format, va_list args);"
+.Ss "  int sfvprintf(Sfio_t* f, const char* format, va_list args);"
+These functions format output data.
+\f5sfprintf()\fP and \f5sfvprintf()\fP write to output stream \f5f\fP.
+\f5sfsprintf()\fP and \f5sfvsprintf()\fP write to buffer \f5s\fP
+which is of size \f5n\fP.
+\f5sfprints()\fP and \f5sfvprints()\fP construct data in some Sfio-defined buffer.
+\f5sfaprints()\fP and \f5sfvaprints()\fP are similar to \f5sfprints()\fP
+and \f5sfvprints()\fP
+but they return a string constructed via \f5malloc()\fP in \f5*sp\fP
+and expect this string to be freed by the caller when no longer needed.
+\f5sfvprintf()\fP is the underlying primitive for the other functions.
+Except for \f5sfprints()\fP and \f5sfvprints()\fP
+which return a null-terminated string or \f5NULL\fP,
+other functions return the number of output bytes or \f5-1\fP on failure.
+
+The length of string constructed by \f5sfprints()\fP, \f5sfsprintf()\fP, or
+\f5sfvsprintf()\fP can be retrieved by \f5sfslen()\fP.
+.PP
+The standard patterns are:
+\f5n, s, c, %, h, i, d, p, u, o, x, X, g, G, e, E, f\fP and \f5!\fP.
+Except for \f5!\fP which shall be described below,
+see the ANSI-C specification of \f5fprintf(3)\fP for details on the other patterns.
+Let \f5z\fP be some pattern type. A formatting pattern is defined as below:
+
+.nf
+.ft 5
+    %[pos$][flag][width][.precision[.base]][(extfdata)]z
+.ft 1
+.fi
+
+.Tp
+\f5pos$\fP:
+A pattern can specify which argument in the argument list to use.
+This is done via \f5pos$\fP where \f5pos\fP is the argument position.
+Arguments are numbered so that the first argument after \f5format\fP is at position 1.
+If \f5pos\fP is not specified, the argument following the most recently used one
+will be used.
+The pattern \f5%!\fP (see below) cannot be used subsequent to a usage of \f5pos$\fP.
+Doing so may cause unexpected behaviors.
+.Tp
+\f5flag\fP:
+The flag characters are
+\f5h\fP, \f5hh\fP, \f5l\fP, \f5ll\fP, \f5L\fP, \f5I\fP, \f5j\fP, \f5t\fP, \f5z\fP,
+\f5\-\fP, \f5+\fP, \fIspace\fP, \f50\fP, \f5'\fP and \f5#\fP.
+
+Flag \f5I\fP defines the size or type of the object being formatted.
+There are two cases: (1) \f5I\fP by itself and (2) \f5I\fP
+followed by either a decimal number or `*'.
+
+In the first case, for integer and floating point patterns,
+the object type is taken to be the largest appropriate type
+(i.e., one of \f5Sflong_t\fP, \f5Sfulong_t\fP or \f5Sfdouble_t\fP).
+For conversion specifiers \f5s\fP and \f5c\fP, the flag is ignored.
+
+In the second case, a given decimal value would define a size while
+`*' would cause the size to be obtained from the argument list.
+Then, if the conversion specifier is \f5s\fP, this size defines the
+length of the string or strings being formatted (see the discussion of \f5base\fP below).
+For integer and floating point patterns,
+the size is used to select a type from one of the below lists as 
+indicated by the conversion specifier:
+
+.nf
+.ft 5
+    Sflong_t, long, int, short
+    Sfulong_t, unsigned long, unsigned int, unsigned short
+    Sfdouble_t, double, float
+.ft 1
+.fi
+
+The selection algorithm always matches types from left to right in any given list.
+Although selection is generally based on sizes in bytes,
+for compatibility with Microsoft-C, the size 64 
+is matched with an appropriate type with the same number of bits, if any.
+If the given size does not match any of the listed types,
+it shall match one of \f5int\fP, \f5unsigned int\fP, and \f5double\fP
+as defined by the formatting pattern.
+
+Below are a few examples of using the \f5I\fP flag.
+The first example prints an \f5Sflong_t\fP integer.
+This example is actually not portable and
+only works on platforms where \f5sizeof(Sflong_t)\fP is 8.
+The second example shows how to that portably.
+The third example specifies printing a string of length 16.
+This length shall be used regardless of whether or not the given string
+is shorter or longer than 16.
+The last example shows the use of the pattern \f5%n\fP to assign the amount
+of data already output into a \f5short\fP integer \f5n_output\fP.
+
+.nf
+.ft 5
+    sfprintf(sfstdout,"%I8d", Sflong_obj);
+    sfprintf(sfstdout,"%I*d", sizeof(Sflong_obj), Sflong_obj);
+    sfprintf(sfstdout,"%I*s", 16, s);
+    sfprintf(sfstdout,"%d%I*n", 1001, sizeof(short), &n_output);
+.ft 1
+.fi
+
+Flags \f5h\fP, \f5l\fP, and \f5L\fP are the ANSI-C conventions to
+select the types of input objects.
+For example, \f5%hd\fP indicates a \f5short int\fP
+while \f5%ld\fP indicates a \f5long int\fP.
+
+Flag \f5hh\fP addresses the byte value types, i.e., \f5char\fP and \f5unsigned char\fP.
+
+Flags \f5z\fP, \f5t\fP and \f5j\fP address respectively
+the types \f5size_t\fP, \f5ptrdiff_t\fP and \f5Sflong_t\fP.
+
+Flags \f5ll\fP and \f5L\fP address respectively
+the largest integer and floating value types, i.e.,
+\f5Sfulong_t\fP, \f5Sflong_t\fP, and \f5Sfdouble_t\fP.
+
+Flag \f5-\fP left-justifies data within the field (otherwise, right-justification).
+
+Flag \f5+\fP means that a signed conversion will always begin with a plus or minus sign.
+
+Flag \fIspace\fP is ignored if \f5+\fP is specified; otherwise,
+it means that if the first character of a signed conversion
+is not a sign or if the result is empty, a space will be prepended.
+
+Flag \f50\fP means padding with zeros on the left.
+
+Flag \f5'\fP outputs thousands-separator used by the current locale.
+\f5setlocale(3)\fP should have been used to set the desired locale.
+
+Flag \f5#\fP indicates an alternative format processing.
+For \f5%o\fP, the first digit is always a zero.
+For \f5%x\fP and \f5%X\fP, a non-zero result will have a prefix
+\f50x\fP or \f50X\fP. For \f5%e\fP, \f5%E\fP, \f5%f\fP, \f5%g\fP, and \f5%G\fP,
+the result always contains a decimal point. For \f5%g\fP and \f5%G\fP,
+trailing zeros will not be removed. For \f5%d\fP, \f5%i\fP and \f5%u\fP,
+the form is \fIbase#number\fP where \fIbase\fP is the conversion base
+and \fInumber\fP is represented by digits for this \fIbase\fP.
+For example, a base \f52\fP conversion with \f5%#..2d\fP for \f510\fP
+is \f52#1010\fP instead of \f51010\fP as printed with \f5%..2d\fP.
+Finally, for \f5%c\fP, bytes will be printed in the C format.
+For example, when the ASCII character set is used,
+the byte value 10 will be printed as \f5\\n\fP while 255 is printed
+as \f5\\377\fP.
+.Tp
+\f5width\fP:
+This defines the width of the printing field. A value to be printed will
+be justified and padded if necessary to fill out the field width.
+.Tp
+\f5precis\fP:
+After a first dot appears, an integral value defines a precision.
+For floating point value patterns, precision is the number of precision digits.
+For \f5%c\fP, precision defines the number of times to repeat the
+character being formatted.
+For \f5%s\fP, precision defines the maximum number of characters to output.
+.Tp
+\f5base\fP:
+This is defined after exactly two dots have appeared.
+
+For \f5%i\fP, \f5%d\fP, and \f5%u\fP,
+\f5base\fP should be an integer value in the inclusive range \f5[2,64]\fP
+and defines a conversion base.
+If \f5base\fP is not in this range, it is defined to be \f510\fP.
+The digits to represent numbers are:
+
+.nf
+.ft 5
+    01234567890
+    abcdefghijklmnopqrstuvwxyz
+    ABCDEFGHIJKLMNOPQRSTUVWXYZ @_
+.ft 1
+.fi
+
+For \f5%s\fP and \f5%c\fP, \f5base\fP defines a separator.
+Then, for \f5%s\fP, the input argument is taken to be a NULL-terminated array of strings
+while, for \f5%c\fP, this is a null-terminated array of characters.
+The strings or characters will be formatted one of a time based
+on the usual width and precision rules.
+After each formatted string or character, except for the last one,
+the separator \f5base\fP is output if it is a non-zero.
+
+There are further restrictions on the syntax of \f5%s\fP and \f5%c\fP when
+a separator is defined.
+Below are the legitimate sequences for \f5%s\fP and \f5%c\fP after the second dot:
+
+.nf
+\f5    s            c\fP
+\f5    *s           *c\fP
+\f5    \fP\fIz\fP\f5s           \fP\fIz\fP\f5c\fP
+.fi
+
+In the first case, no separator is defined so \f5base\fP is set to zero.
+In the second case, \f5base\fP is obtained from the argument list.
+In the third case, the character \fIz\fP
+must be non-alphanumeric and \f5base\fP will be set to this character.
+
+The below example shows both the call and the result
+of printing a \f5NULL\fP-terminated array
+of three strings \f5apple\fP, \f5orange\fP, and \f5grape\fP:
+
+.nf
+.ft 5
+    sfprintf(sfstdout,"|%8..:s|",list);
+    |   apple:  orange:   grape|
+.ft 1
+.fi
+
+.Tp
+\f5(extfdata)\fP:
+This defines a string \f5extfdata\fP
+to be passed to the extension function \f5Sffmt_t.extf\fP.
+Parentheses shall be balanced.
+If \f5extfdata\fP is \f5*\fP, the string is obtained from the argument list.

+.PP
+A white space character (blank, tab, or new-line) in \f5format\fP
+normally matches a maximal sequence of input white space characters.
+However, if the input stream is in \f5SF_LINE\fP mode (see \f5sfset()\fP),
+a new-line character only matches white spaces up to an input new-line character.
+This is useful to avoid blocking when scanning typed inputs.
+.PP
+The standard scan patterns are:
+\f5i, d, u, o, x, X, p, n, f, e, E, g, G, c, %, s, []\fP and \f5!\fP.
+Except for \f5!\fP which shall be described below,
+see the ANSI-C specification of \f5fscanf(3)\fP for details on other patterns.
+Let \f5z\fP be some pattern type. A formatting pattern is specified as below:
+
+.nf
+.ft 5
+    %[*][pos$][width][.width.base][(extfdata)][flag]z
+.ft 1
+.fi
+
+.Tp
+\f5pos$\fP:
+A pattern can specify which argument in the argument list to use.
+This is done via \f5pos$\fP where \f5pos\fP is the argument position.
+Arguments are numbered so that the first argument after \f5format\fP is at position 1.
+If \f5pos\fP is not specified, the argument following the most recently used one
+will be used.
+The pattern \f5%!\fP (see below) cannot be used subsequent to a usage of \f5pos$\fP.
+.Tp
+\f5*:\fP
+This discards the corresponding scanned item.
+.Tp
+\f5width\fP and \f5base\fP:
+\f5width\fP defines the maximum number of bytes to scan
+and \f5base\fP defines the base of an integral value being scanned.
+The `.' (dot) notation also allows specifying a `*' (star) to obtain
+the value from the argument list. The below example specifies scanning
+4 bytes to obtain the value of an integer in base 10. At the end of scanning,
+the variable \f5v\fP should have the value \f51234\fP.
+
+.nf
+.ft 5
+    sfsscanf("12345678","%.*.*d", 4, 10, &v);
+.ft 1
+.fi
+
+.Tp
+\f5(extfdata)\fP:
+This defines a string \f5extfdata\fP
+to be passed to the extension function \f5Sffmt_t.extf\fP.
+Parentheses shall be balanced.
+If \f5extfdata\fP is \f5*\fP, the string is obtained from the argument list.
+.Tp
+\f5flag:\fP
+This is \f5#\fP, \f5I\fP, or some sequence of \f5h\fP, \f5l\fP, and \f5L\fP.
+
+Flag \f5#\fP is significant for pattern \f5%i\fP and \f5%[\fP.
+For \f5%i\fP, it means that the \f5#\fP symbol does not have its usual
+meaning in an input sequence \f5base#value\fP.
+For example, the scanning result of \f5%#i\fP on input \f52#1001\fP is \f52\fP
+and the next \f5sfgetc()\fP call will return \f5#\fP.
+For \f5%[\fP, if the next character in the input stream does not match
+the given scan set of characters, \f5#\fP causes a match to a null string
+instead of a failure.
+
+Flag \f5I\fP defines the size or type of the object being formatted.
+There are two cases: (1) \f5I\fP by itself and (2) \f5I\fP
+followed by either a decimal number or `*'.
+
+In the first case, for integer and floating point patterns,
+the object type is taken to be the largest appropriate type
+(i.e., one of \f5Sflong_t\fP, \f5Sfulong_t\fP or \f5Sfdouble_t\fP).
+For string patterns such as \f5%s\fP, the flag is ignored.
+
+In the second case, a given decimal value would define a size while
+`*' would cause the size to be obtained from the argument list.
+For string patterns such as \f5%s\fP or \f5%[\fP, this size defines the
+length of the buffer to store scanned data.
+Specifying a buffer size only limits the amount of data copied into the buffer.
+Scanned data beyond the buffer limit will be discarded.
+For integer and floating point patterns,
+the size is used to select a type from one of the below lists as
+indicated by the conversion specifier:
+
+.nf
+.ft 5
+    Sflong_t, long, int, short
+    Sfulong_t, unsigned long, unsigned int, unsigned short
+    Sfdouble_t, double, float
+.ft 1
+.fi
+
+The selection algorithm always matches types from left to right in any given list.
+Although selection is generally based on sizes in bytes,
+for compatibility with Microsoft-C, the size 64 
+is matched with an appropriate type with the same number of bits, if any.
+If the given size does not match any of the listed types,
+it shall match one of \f5int\fP, \f5unsigned int\fP, and \f5double\fP
+as indicated by the formatting pattern.
+
+Below are examples of using the \f5I\fP flag.
+The first example scans a 64-bit integer.
+The second scans some floating point value
+whose size is explicitly computed and given.
+The last example scans a string into a buffer with the given size 128.
+Note that if the scanned string is longer than 127, only the first 127
+bytes shall be copied into the buffer. The rest of the scanned data
+shall be discarded.
+
+.nf
+.ft 5
+     sfscanf(sfstdin,"%I64d", &int64_obj);
+     sfscanf(sfstdin,"%I*f", sizeof(float_obj), &float_obj);
+     sfscanf(sfstdin,"%I*s", 128, buffer);
+.ft 1
+.fi
+
+Flags \f5h\fP, \f5l\fP, and \f5L\fP are the ANSI-C conventions
+for indicating the type of a scanned element.
+For example, \f5%hd\fP means scanning a \f5short int\fP.
+The flags \f5ll\fP and \f5L\fP mean respectively scanning an
+integer or a floating point value with largest size
+(i.e, \f5Sflong_t\fP or \f5Sfdouble_t\fP).
+.PP
+The \f5%i\fP, \f5%d\fP and \f5%u\fP patterns scan numbers in bases
+from \f52\fP to \f564\fP.
+\f5%i\fP scans integral values in self-describing formats.
+Except for octal, decimal and hexadecimal numbers with the usual formats,
+numbers in general bases are assumed to be of the form: \fIbase#value\fP
+where \fIbase\fP is a number in base 10 and \fIvalue\fP
+is a number in the given base.
+For example, \f52#1001\fP is the binary representation of the decimal value \f59\fP.
+If \fIbase\fP is \f536\fP or less,
+the digits for \fIvalue\fP can be any combination of \f5[0-9], [a-z], [A-Z]\fP
+where upper and lower case digits are not distinguishable.
+If \fIbase\fP is larger than \f536\fP, the set of digits is:

+.PP
+.Ss "  Void_t* sfsetbuf(Sfio_t* f, Void_t* buf, size_t size)"
+This function changed the buffering scheme for the stream \f5f\fP.
+The stream will be synchronized before any buffer modification.
+If a new buffer is successfully set and the old buffer has not been freed,
+\f5sfsetbuf()\fP returns the old buffer. Otherwise, it returns \f5NULL\fP.
+After a \f5sfsetbuf()\fP call,
+\f5sfvalue()\fP returns the size of the returned buffer.
+
+Sfio attempts to read data in blocks likely to be serviced fast by the file system.
+This means block sizes being multiples of a suitable alignment value
+(e.g., 512, 1024 or 8192). By default, the alignment value
+is computed via some internal mechanism depending on the local platform but
+it can also be explicitly set via the call \f5sfsetbuf(f, (Void_t*)f, size)\fP.
+
+In invocations of \f5sfsetbuf()\fP other than the above case,
+the \f5size\fP argument is treated as follows:
+.Tp
+\f5size == SF_UNBOUND\fP:
+Sfio will pick a suitable buffer size.
+If \f5buf\fP is \f5NULL\fP,
+Sfio will also pick a suitable buffering scheme (such as memory mapping.)
+If \f5buf\fP is not \f5NULL\fP, its actual value is ignored
+but the buffer will be allocated via \f5malloc(3)\fP.
+This can be used to avoid memory mapping.
+.Tp
+\f5size > 0\fP:
+This is the suggested size to use for buffering or memory mapping.
+If \f5buf\fP is \f5NULL\fP,
+Sfio will pick a suitable buffering scheme as discussed above.
+If \f5buf\fP is not \f5NULL\fP, then \f5buf\fP and \f5size\fP determine
+a buffer of the given size.
+.Tp
+\f5size == 0\fP:
+If \f5buf\fP is \f5NULL\fP, the stream will be unbuffered.
+If \f5buf\fP is not \f5NULL\fP,
+\f5sfsetbuf()\fP simply returns the stream buffer.
+In this case, no attempt will be made to synchronize the stream.
+
+.Ss "  int sfsync(Sfio_t* f)"
+This function synchronizes the logical and physical views of stream \f5f\fP.
+It returns a negative value for failure and \f50\fP for success.
+
+For a \f5SF_WRITE\fP stream, synchronization means to write out any buffered data.
+For a seekable \f5SF_READ\fP file stream,
+the physical file position is aligned with the logical stream position and,
+if \f5SF_SHARE\fP is on, buffered data is discarded.
+If \f5f\fP is \f5NULL\fP, all streams are synchronized.
+If \f5f\fP is the base of a stream stack (see \f5sfstack()\fP),
+all stacked streams are synchronized.
+Note that a stacked stream can only be synchronized this way.
+If \f5f\fP is in a pool (see \f5sfpool()\fP) but not being the head,
+the pool head is synchronized.
+
+If \f5f\fP has flag \f5SF_IOCHECK\fP, the \f5SF_SYNC\fP event is raised
+before and after synchronization. See \f5sfdisc()\fP for details.
+
+.Ss "  int sfpoll(Sfio_t** flist, int n, int timeout)"
+This function polls a set of streams to see if I/O operations
+can be performed on them without blocking.
+This is useful for multiplexing I/O over a set of streams.
+If a stream has a discipline, the exception function may be called
+before and after the stream is polled (see \f5sfdisc()\fP for details).
+After a successful \f5sfpoll()\fP call,
+for each ready stream \f5f\fP, \f5sfvalue(f)\fP returns
+a bit combination of \f5SF_READ\fP and \f5SF_WRITE\fP to tell which I/O
+mode is available. If \f5SF_READ\fP is available, an attempt to read
+a byte will not block. If \f5SF_WRITE\fP is available,
+an attempt to flush will not block.
+\f5sfpoll()\fP returns the number of ready streams or \f5-1\fP on failure.
+.Tp
+\f5flist\fP and \f5n\fP:
+\f5flist\fP is an array of \f5n\fP streams to be polled.
+Upon return, ready streams are moved to the front
+of \f5flist\fP in the same relative order.
+.Tp
+\f5timeout\fP:
+This defines an elapse time in milliseconds
+to wait to see if any stream is ready for I/O.
+If \f5timeout\fP is negative, \f5sfpoll()\fP will block until some stream become ready.
+Note that \f5SF_STRING\fP and normal file streams never block
+and are always ready for I/O.
+If a stream with discipline is being polled and
+its readiness is as yet undetermined (e.g., empty buffer,)
+the discipline exception function will be called with \f5SF_DPOLL\fP
+before querying the operating system.
+
+.Ss "  Sfio_t* sfpool(Sfio_t* f, Sfio_t* poolf, int mode)"
+This function manipulates pools of streams.
+In a pool, only one stream is at the head and can have buffered data.
+All other streams in the pool will be synchronized.
+A stream becomes head when it is used for some I/O operation.
+\f5sfpool()\fP returns \f5NULL\fP on failure.
+.Tp
+\f5f\fP and \f5poolf\fP:
+If \f5f\fP is \f5NULL\fP,
+\f5sfpool()\fP simply returns the head of the pool containing \f5poolf\fP.
+If \f5f\fP is not \f5NULL\fP and \f5poolf\fP is \f5NULL\fP,
+\f5f\fP is deleted from its pool.
+In this case, if no other stream from the same pool can become head,
+\f5sfpool()\fP will return \f5NULL\fP; otherwise, it returns some stream
+from the remainder of the pool.
+If both \f5f\fP and \f5poolf\fP are not \f5NULL\fP,
+\f5f\fP is moved from its current pool (if any)
+into the same pool with \f5poolf\fP.
+In this case, \f5poolf\fP is returned.
+.Tp
+\f5mode\fP:
+If \f5poolf\fP is already in a pool, \f5mode\fP is ignored.
+Otherwise, \f5mode\fP should be \f50\fP or \f5SF_SHARE\fP.
+A \f5SF_SHARE\fP pool contains streams with \f5SF_WRITE\fP mode.
+In addition, on change to a new head stream,
+buffered write data of the current head
+is transferred to the new head.
+
+.Ss "  int sfpurge(Sfio_t* f)"
+This function discards all buffered data
+unless \f5f\fP is a \f5SF_STRING\fP stream.
+Note that if \f5f\fP is a \f5SF_READ\fP stream based on an unseekable device,
+purged data will not be recoverable.
+If \f5f\fP is a \f5sfpopen\fP-stream opened for both read and write,
+data of both the read and write pipe ends will be purged
+(see \f5sfset()\fP to selectively turn off read or write mode
+if one set of data is to be preserved.)
+After purging, if \f5f\fP has flag \f5SF_IOCHECK\fP,
+the event \f5SF_PURGE\fP is raised.
+\f5sfpurge()\fP returns \f5-1\fP for failure and \f50\fP for success.

+.PP
+.Ss "DISCIPLINE, EVENT-HANDLING"
+.PP
+A file stream uses the system calls \f5read(2)\fP, \f5write(2)\fP
+and \f5lseek(2)\fP to read, write and position in the underlying file.
+Disciplines enable application-defined I/O methods including exception handling and
+data pre/post-processing.
+
+.Ss "  Sfdisc_t* sfdisc(Sfio_t* f, Sfdisc_t* disc)"
+Each stream has a discipline stack whose bottom is a virtual discipline
+representing the actual system calls.
+\f5sfdisc()\fP manipulates the discipline stack of stream \f5f\fP.
+\f5f\fP will be synchronized before any discipline stack manipulation.
+After a successful discipline stack manipulation,
+the stream I/O position (see \f5sfseek()\fP and \f5sftell()\fP)
+and extent (see \f5sfsize()\fP) are updated
+to reflect that defined by the top discipline.
+If \f5disc\fP is \f5SF_POPDISC\fP or \f5(Sfdisc_t*)0\fP,
+the top element of the stack, if any, is popped and its address is returned.
+Otherwise, \f5disc\fP is pushed onto the discipline stack.
+In this case, if successful, \f5sfdisc()\fP returns
+the discipline that was pushed down.
+\f5sfdisc()\fP returns \f5NULL\fP on failure.
+
+Note that a discipline can be used only on one stream at a time.
+An application should take care to allocate different discipline
+structures for use with different streams. 
+A discipline structure is of the type \f5Sfdisc_t\fP which
+contains the following public fields:
+
+.nf
+.ft 5
+    Sfread_f   readf;
+    Sfwrite_f  writef;
+    Sfseek_f   seekf;
+    Sfexcept_f exceptf;
+.ft 1
+.fi
+
+.PP
+The first three fields of \f5Sfdisc_t\fP specify alternative I/O functions.
+If any of them is \f5NULL\fP, it is inherited
+from a discipline pushed earlier on the stack.
+Note that a file stream always
+has \f5read(2)\fP, \f5write(2)\fP, \f5lseek(2)\fP and \f5NIL(Sfexcept_f)\fP
+as the \fIlogical bottom discipline\fP.
+Arguments to I/O discipline functions
+have the same meaning as that of the
+functions \f5sfrd()\fP, \f5sfwr()\fP and \f5sfsk()\fP described below.
+.PP
+The exception function, \f5(*exceptf)()\fP announces exceptional events during
+I/O operations.
+It is called as \f5(*exceptf)(Sfio_t* f, int type, Void_t* value, Sfdisc_t* disc)\fP.
+Unless noted otherwise, the return value of \f5(*exceptf)()\fP is used as follows:
+.Tp
+\f5<0\fP:
+The on-going operation shall terminate.
+.Tp
+\f5>0\fP:
+If the event was raised due to an I/O error,
+the error has been repaired and the on-going operation shall continue normally.
+For some events, e.g., \f5SF_DPOLL\fP, the return value may also have
+additional meanings.
+.Tp
+\f5=0\fP:
+The on-going operation performs default actions with respect to the raised event.
+For example, on a reading error or reaching end of file, the top stream of a stack
+will be popped and closed and the on-going operation continue with the new top
+stream.
+.PP
+The argument \f5type\fP of \f5(*exceptf)()\fP
+identifies the particular exceptional event:
+.Tp
+\f5SF_LOCKED\fP:
+The stream cannot be accessed.
+Note that this lock state is not related to the mutex lock
+that protects a stream from multiple accesses by different threads
+(see section THREAD SAFETY). Rather, the stream was frozen by
+certain operations such as \f5sfreserve()\fP or \f5sfstack()\fP.
+Thus, a stream can be in this state even if the application is uni-threaded.
+.Tp
+\f5SF_READ\fP, \f5SF_WRITE\fP:
+These events are raised around reading and writing operations.
+
+If \f5SF_IOCHECK\fP is on, \f5SF_READ\fP and \f5SF_WRITE\fP
+are raised immediately before \f5read(2) and write(2)\fP calls.
+In this case, \f5*((ssize_t*)value)\fP is the amount of data to be processed.
+The return value of \f5(*exceptf)()\fP, if negative,
+indicates that the stream is not ready for I/O
+and the calling operation will abort with failure.
+If it is positive, the stream is ready for I/O
+but the amount should be restricted to the amount specified by this value.
+If the return value is zero, the I/O operation is carried out normally.
+
+\f5SF_READ\fP and \f5SF_WRITE\fP are also raised on operation failures.
+In such a case, \f5*((ssize_t*)value)\fP
+is the return value from the failed operation.
+.Tp
+\f5SF_SEEK\fP:
+This event is raised when a seek operation fails.
+.Tp
+\f5SF_NEW\fP, \f5SF_CLOSING\fP (\f5SF_CLOSE\fP), \f5SF_FINAL\fP:
+These events are raised during a stream closing.
+\f5SF_NEW\fP is raised for a stream about to be closed to be renewed (see \f5sfnew()\fP).
+\f5SF_CLOSING\fP is raised for a stream about to be closed.
+\f5SF_FINAL\fP is raised after a stream has been closed and before
+its space is to be destroyed (see \f5sfclose()\fP).
+For these events, a non-zero return value from \f5(*exceptf)()\fP causes
+\f5sfclose()\fP to return immediately with the same value.
+.Tp
+\f5SF_DPUSH\fP, \f5SF_DPOP\fP, \f5SF_DBUFFER\fP:
+Events \f5SF_DPUSH\fP and \f5SF_DPOP\fP are raised when a
+discipline is about to be pushed or popped.
+\f5(Sfdisc_t*)value\fP is the to-be top discipline, if any.
+
+A stream buffer is always synchronized before pushing or popping a discipline.
+If this synchronization fails, \f5SF_DBUFFER\fP will be raised with
+\f5*((size_t*)value)\fP being the amount of buffered data.
+If the return value of \f5exceptf\fP is positive,
+the push or pop operation will continue normally;
+otherwise, \f5sfdisc()\fP returns failure.
+.Tp
+\f5SF_DPOLL\fP:
+This event is raised by
+\f5sfpoll()\fP to see if the stream is ready for I/O.
+\f5*((int*)value)\fP indicates a time-out interval to wait.
+A negative return value from the exception function means blocking.
+A zero return value means that \f5sfpoll()\fP should
+query the underlying file descriptor.
+A positive return value means non-blocking. In addition,
+this value will be a bit combination of \f5SF_READ\fP and \f5SF_WRITE\fP
+to indicate what I/O modes are ready.
+.Tp
+\f5SF_READY\fP:
+This event is raised by \f5sfpoll()\fP for each ready stream.
+The third argument to the event handler is an integer composed with
+the two bits \f5SF_READ\fP and \f5SF_WRITE\fP to indicate which
+I/O modes are ready.
+.Tp
+\f5SF_SYNC\fP, \f5SF_PURGE\fP:
+If \f5SF_IOCHECK\fP is set,
+these events are raised respectively for a \f5sfsync()\fP or \f5sfpurge()\fP call. 
+In each case, the respective event is raised once before the appropriate
+operation (synchronization or purging) with \f5((int)value)\fP being \f51\fP
+and once after with \f5((int)value)\fP being \f50\fP.
+Note that \f5sfsync()\fP is called for each
+\f5SF_WRITE\fP or \f5SF_SHARE|SF_READ\fP stream on closing.
+
+.Tp
+\f5SF_ATEXIT\fP:
+This event is raised for each open stream before the process exits.
+
+.Ss "  int sfraise(Sfio_t* f, int type, Void_t* data)"
+If \f5f\fP is non-\f5NULL\fP, \f5sfraise()\fP calls all exception handlers
+of \f5f\fP with the event \f5type\fP and associated \f5data\fP.
+If an exception handler returns a non-zero value,
+\f5sfraise()\fP immediate returns the same value.
+Application-defined events should start from the value \f5SF_EVENT\fP
+so as to avoid confusion with system-defined events,
+\f5sfraise()\fP returns \f50\fP on success and \f5-1\fP on failure.
+
+If \f5f\fP is \f5NULL\fP, \f5sfraise()\fP iterates over all streams
+and raise events as described above. In this case,
+\f5sfraise()\fP returns \f50\fP on success and a negative value
+on failure. The absolute value of the return value tells how many

+They should not be used in any other context.
+\f5sfrd()\fP and \f5sfwr()\fP return the number of bytes read or written.
+\f5sfsk()\fP returns the new seek position.

+.Ss "  int sfresize(Sfio_t* f, Sfoff_t size)"
+This function resizes the stream \f5f\P so that its extent is \f5size\fP.

+via the system call \f5ftruncate()\fP.
+When a stream is made larger, the new data space is filled with zero's.
+\f5sfresize()\fP returns \f50\fP on success and a negative value on failure.

+\f5SF_LINE\fP, \f5SF_SHARE\fP, \f5SF_PUBLIC\fP, \f5SF_MALLOC\fP and
+\f5SF_STATIC\fP.
+Note that \f5SF_READ\fP and \f5SF_WRITE\fP can be turned on or off only
+if the stream was opened as \f5SF_READ|SF_WRITE\fP.
+Turning off one of them means that the stream is to be treated exclusively
+in the other mode. It is not possible to turn off both.
+If legal, an attempt to turn on either \f5SF_READ\fP or \f5SF_WRITE\fP
+will cause the stream to be in the given I/O mode.
+.Tp
+\f5set == 0:\fP
+If \f5flags\fP is zero, the current set of flags is simply returned.
+Note that when a stream is first opened, not
+all of its flags are initialized yet (more below). If \f5flags\fP is
+non-zero, an attempt is made to turn off the specified flags.
+.Tp
+\f5set != 0:\fP
+If \f5flags\fP is zero, the stream is initialized if not yet done so.

+.Ss "  Sfio_t* sfstack(Sfio_t* base, Sfio_t* top)"
+This function stacks or unstacks stream.
+Every stream stack is identified by a base stream
+via which all I/O operations are performed.
+However, an I/O operation always takes effect on the top stream.
+If the top stream reaches the end of file or
+has an unrecoverable error condition,
+it is automatically popped and closed
+(see also \f5sfdisc()\fP for alternative handling of these conditions).
+.Tp
+\f5base\fP:
+This is the base stream of the stack.
+If it is \f5NULL\fP, \f5sfstack()\fP does nothing and returns \f5top\fP.
+.Tp
+\f5top\fP:
+If this is \f5SF_POPSTACK\fP or \f5(Sfio_t*)0\fP,
+the stack is popped and \f5sfstack()\fP returns the popped stream.
+Otherwise, \f5top\fP is pushed on top of the stack identified by \f5base\fP
+and \f5sfstack()\fP returns the \f5base\fP stream.
+
+.Ss "  Sfio_t* sfswap(Sfio_t* f1, Sfio_t* f2)"
+This function swaps contents of \f5f1\fP and \f5f2\fP.
+This fails if either stream is in a stream stack but not being a base stream.
+If \f5f2\fP is \f5NULL\fP, a new stream is constructed as a duplicate of \f5f1\fP.
+\f5sfswap()\fP returns \f5f2\fP or \f5f1\fP duplicate on success and
+\f5NULL\fP on failure.
+
+.PP
+.Ss "STREAM INFORMATION"
+.PP
+.Ss "  Sfoff_t sfsize(Sfio_t* f)"
+This function returns the size of stream \f5f\fP (see \f5sfnew()\fP).
+If \f5f\fP is not seekable or if its size is not determinable,
+\f5sfsize()\fP returns \f5-1\fP.
+
+.Ss "  Sfoff_t sftell(Sfio_t* f)"
+This function returns the current I/O position in stream \f5f\fP.
+Note that if \f5f\fP is \f5SF_APPEND\fP
+and a writing operation was just performed,
+the current I/O position is at the physical end of file.
+If \f5f\fP is unseekable, \f5sftell\fP returns the number of bytes
+read from or written to \f5f\fP.
+See also \f5sfungetc()\fP.
+
+.Ss "  ssize_t sfvalue(Sfio_t* f)"
+This function returns the string or buffer length
+for \f5sfreserve()\fP, \f5sfsetbuf()\fP, and \f5sfgetr()\fP.
+
+.Ss "  int sffileno(Sfio_t* f)"
+This function returns the file descriptor of stream \f5f\fP.
+
+.Ss "  int sfstacked(Sfio_t* f)"
+This function returns a non-zero value
+if stream \f5f\fP has been stacked.
+
+.Ss "  int sfeof(Sfio_t* f)"
+.Ss "  int sferror(Sfio_t* f)"
+.Ss "  int sfclrerr(Sfio_t* f)"
+\f5sfeof()\fP tells whether or not the stream has an end-of-file condition.
+\f5sferror()\fP tells whether or not the stream has an error condition.
+\f5sfclrerr()\fP clears both end-of-file and error conditions.
+The end-of-file and error conditions are also cleared on an I/O operation.
+
+.Ss "  int sfclrlock(Sfio_t* f)"
+This function restores the stream back to a normal state.
+This means clearing locks and possibly throwing away unprocessed data.
+As such, this operation is unsafe and should be used with care.
+For example, it may be used before a long jump (\f5longjmp(3)\fP)
+out of some discipline I/O function to restore the internal stream states.
+\f5sfclrlock()\fP returns the current set of flags.
+
+.Ss "  int sfnotify((void(*)notify)(Sfio_t*, int, int) )"
+This sets a function \f5(*notify)()\fP to be called
+as \f5(*notify)(f,type,file)\fP on various stream events.
+Arguments \f5f\fP and \f5file\fP are stream and related file descriptor.
+Argument \f5type\fP indicates the reason for the call:
+.Tp
+\f5SF_NEW\fP:
+\f5f\fP is being opened and \f5file\fP is the underlying file descriptor.
+.Tp
+\f5SF_CLOSING\fP (\f5SF_CLOSE\fP):
+\f5f\fP and \f5file\fP are being closed.
+.Tp
+\f5SF_SETFD\fP:
+The file descriptor of \f5f\fP is being changed to \f5file\fP (see \f5sfsetfd()\fP.)
+.Tp
+\f5SF_READ\fP:
+An attempt to change \f5f\fP to read mode failed.
+.Tp
+\f5SF_WRITE\fP:
+An attempt to change \f5f\fP to write mode failed.
+
+.PP
+.Ss "MISCELLANEOUS FUNCTIONS"
+.PP
+.Ss "  ssize_t sfmaxr(ssize_t maxr, int set)"
+Certain records may require too much memory for storage, thus, causing
+undesirable side effects. Therefore, the library normally bounds the amount
+of memory used by \f5sfgetr()\fP. A different memory bound
+can be set via \f5sfmaxr()\fP. While a positive \f5maxr\fP hints to \f5sfgetr()\fP
+to use only about that much memory to construct a record, a non-positive bound
+allows \f5sfgetr()\fP to use as much memory as necessary.
+\f5sfmaxr()\fP sets the value only if \f5set\fP is non-zero.
+It returns the value before setting or the current value if not setting.
+
+.Ss "  ssize_t sfslen()"
+This function returns the length of a string just constructed
+by \f5sfsprintf()\fP or \f5sfprints()\fP.  See also \f5sfvalue()\fP.
+
+.Ss "  int sfulen(Sfulong_t v)"
+.Ss "  int sfllen(Sflong_t v)"
+.Ss "  int sfdlen(Sfdouble_t v)"
+These functions return respectively the number of bytes required to code the
+\f5Sfulong_t\fP, \f5Sflong_t\fP or \f5Sfdouble_t\fP value \f5v\fP by \f5sfputu()\fP,
+\f5sfputl()\fP or \f5sfputd()\fP.
+
+.Ss "  ssize_t sfpkrd(int fd, char* buf, size_t n, int rsc, long tm, int action)"
+This function acts directly on the file descriptor \f5fd\fP.
+It does a combination of peeking on incoming data and a time-out read.
+Upon success, it returns the number of bytes received.
+A return value of \f50\fP means that the end-of-file condition has been detected.
+A negative value represents an error.
+.Tp
+\f5buf\fP, \f5n\fP:
+These define a buffer and its size to read data into.
+.Tp
+\f5rsc\fP:
+If \f5>=0\fP, this defines a record separator.
+If the last returned byte is not the record separator, then
+the read data did not contain a complete record. Otherwise,
+it contains one or more records.
+See also \f5action\fP below.
+.Tp
+\f5tm\fP:
+If \f5>=0\fP, this defines a time interval in milliseconds to wait for incoming data.
+.Tp
+\f5action\fP:
+If \f5action > 0\fP, \f5sfpkrd()\fP will peek on incoming data but
+will not read past it. Therefore, a future \f5sfpkrd()\fP or \f5read(2)\fP will see
+the same data again.
+If \f5action <= 0\fP, \f5sfpkrd()\fP will not peek and there are two cases.
+If \f5rsc < 0\fP, an attempt is made to read \f5n\fP bytes.
+If \f5rsc >= 0\fP, an attempt is made to read one record.
+
+.PP
+.Ss "FULL STRUCTURE SFIO_T"
+.PP
+.Ss "  #include <sfio_t.h>"
+Most applications based on Sfio only need to include
+the header file \f5sfio.h\fP which defines an abbreviated \f5Sfio_t\fP
+structure without certain fields private to Sfio.
+However, there are times (e.g., debugging)
+when an application may require more details about the full \f5Sfio_t\fP structure.
+In such cases, the header file \f5sfio_t.h\fP can be used in place of \f5sfio.h\fP.
+Note that an application doing this will become sensitive to changes
+in the internal architecture of Sfio.
+
+.Ss "  #define SFNEW(buf,size,file,flags,disc)"
+This macro function is defined in \f5sfio_t.h\fP for
+use in static initialization of an \f5Sfio_t\fP structure.
+It requires five arguments:
+.Tp
+\f5buf, size\fP:
+These define a buffer and its size.
+.Tp
+\f5file\fP:
+This defines the underlying file descriptor if any.
+.Tp
+\f5flags\fP:
+This is composed from bit flags described above.
+.Tp
+\f5disc\fP:
+This defines a discipline if any.
+
+.PP
+.Ss "EXAMPLE DISCIPLINES"
+.PP
+The below functions create disciplines and insert them into
+the given streams \f5f\fP. These functions return \f50\fP
+on success and \f5-1\fP on failure.
+
+.Ss "int sfdcdio(Sfio_t* f, size_t bufsize)"
+This creates a discipline that uses the direct IO feature
+available on file systems such as SGI's XFS to speed up IO.
+The argument \f5bufsize\fP suggests a buffer size to use for data transfer.
+
+.Ss "int sfdcdos(Sfio_t* f)"
+This creates a discipline to read DOS text files.
+It basically transforms pairs of \er\en to \en.
+
+.Ss "int sfdcfilter(Sfio_t* f, const char* cmd)"
+This creates a discipline that sends data from \f5f\fP
+to the given command \f5cmd\fP to process, then reads back the processed data.
+
+.Ss "int sfdcseekable(Sfio_t* f)"
+This creates a discipline that makes an unseekable reading stream seekable.
+
+.Ss "int sfdcslow(Sfio_t* f)"
+This creates a discipline that makes all Sfio operations return immediately
+on interrupts. This is useful for dealing with slow devices.
+
+.Ss "int sfdcsubstream(Sfio_t* f, Sfio_t* parent, Sfoff_t offset, Sfoff_t extent)"
+This creates a discipline that makes \f5f\fP acts as if it
+corresponds exactly to the subsection of \f5parent\fP
+starting at \f5offset\fP with size \f5extent\fP.
+
+.Ss "int sfdctee(Sfio_t* f, Sfio_t* tee)"
+This creates a discipline that copies to the stream \f5tee\fP
+any data written to \f5f\fP.
+
+.Ss "int sfdcunion(Sfio_t* f, Sfio_t** array, int n)"
+This creates a discipline that makes \f5f\fP act as if it is
+the concatenation of the \f5n\fP streams given in \f5array\fP.
+
+.Ss "int sfdclzw(Sfio_t* f)"
+This creates a discipline that would decompress data in \f5f\fP.
+The stream \f5f\fP should have data from a source compressed by
+the Unix \fBcompress\fP program.
+
+.Ss "int sfdcgzip(Sfio_t* f, int opt)"
+This creates a discipline for reading/writing data compressed by zlib.
+The argument \f5opt\fP defines the optimization level.
+
+.PP
+.Ss "STDIO-COMPATIBILITY"
+.PP
+Sfio provides compatibility functions for all various popular
+Stdio implementations at source and binary level.
+The source Stdio-compatibility interface
+provides the header file \f5stdio.h\fP that defines
+a set of macros or inlined functions to map Stdio calls to Sfio ones.
+This mapping may benignly extend or change the meaning of certain
+original Stdio operations. For example, the Sfio's version of
+\f5popen()\fP allows a coprocess to be opened for both reading and writing
+unlike the original call which only allows a coprocess to be opened for a single mode.
+Similarly, the Sfio's \f5fopen()\fP call can be used to create
+string streams in addition to file streams.
+.PP
+The standard streams \f5stdin\fP, \f5stdout\fP and \f5stderr\fP
+are mapped via \f5#define\fP to \f5sfstdin\fP, \f5sfstdout\fP and \f5sfstderr\fP.
+The latter are typically declared of the type \f5Sfio_t*\fP.
+Certain older Stdio applications require these to be declared
+as addresses of structures so that static initializations of
+the sort ``\f5FILE*\ f\ =\ stdin;\fP'' would work.
+Such applications should use the compile time flag \f5SF_FILE_STRUCT\fP
+to achieve the desired effect.
+.PP
+The binary Stdio-compatibility libraries, \f5libstdio.a\fP and \f5libstdio-mt.a\fP,
+provide complete implementations of Stdio functions suitable
+for linking applications already compiled with native header \f5stdio.h\fP.
+These functions are also slightly altered or extended
+as discussed above.
+.PP
+Below are the supported Stdio functions:
+.PP

+.Ss "RECENT CHANGES"
+.PP
+A few exception types have been added. In particular, exception handlers shall
+be raised with \f5SF_LOCKED\fP on accessing a stream frozen either by
+an ongoing operation or a previous operation (e.g., \f5sfgetr()\fP).
+Before a process exits, the event \f5SF_ATEXIT\fP is raised for each open stream.
+.PP
+A number of disciplines were added for various processing functions.
+Of interests are disciplines to use the direct I/O feature on IRIX6.2,
+read DOS text files, and decompress files compressed by Unix \fIcompress\fP.
+.PP
+Various new stream and function flags have been added. For example,
+the third argument of \f5sfgetr()\fP is now a set of bit flags and not
+just a three-value object. However, the old semantics of this argument
+of \f5sfgetr()\fP is still supported.
+.PP
+The \f5sfopen()\fP call has been extended so that sfopen(f,NULL,mode) can be
+used to changed the mode of a file stream before any I/O operations.
+This is most useful for changing the modes of the standard streams.
+.PP
+The buffering strategy has been significantly enhanced for streams
+that perform many seek operations. Also, the handling of stream and
+file positions have been better clarified so that applications that
+share file descriptors across streams and/or processes can be sure that
+the file states will be consistent.
+.PP
+The strategy for mapping between Sfio and Stdio streams in the binary
+compatibility package has been significantly enhanced for efficiency.
+For most platforms, the mapping is now constant time per look-up.
+.PP
+The \f5SF_BUFCONST\fP flag was deleted. This is largely unused anyway.
+.PP
+The library can be built for thread-safety. This is based largely on
+Posix pthread mutexes except for on UWIN where native Windows APIs
+are used.
+.PP
+The functions \f5sfgetm()\fP and \f5sfputm()\fP were added to encode
+unsigned integer values with known ranges.
+.PP
+The flag \f5SF_APPEND\fP is identical to \f5SF_APPENDWR\fP.
+However it conflicts with a different token of the same name
+defined in the system header \f5stat.h\fP of BSDI Unix systems.
+On such systems, we shall not define \f5SF_APPEND\fP and this
+symbol may be removed in a future release.
+.PP
+Similarly, the exception \f5SF_CLOSE\fP is identical to \f5SF_CLOSING\fP.
+However it conflicts with a different token of the same name
+defined in the system header \f5socket.h\fP of AIX Unix systems.
+On such systems, we shall not define \f5SF_CLOSE\fP and this
+symbol may be removed in a future release.
+.PP
+The printing and scanning functions were extended to handle multibyte characters
+and to conform to the C99 standard.
+.PP
+The function \f5sfpoll()\fP was rehauled to make it useful
+for writing servers that must commnunicate with multiple streams
+without blocking.
+.PP
+The formatting pattern \f5%c\fP for \f5sf*printf\fP was extended
+to allow the flag \f5#\fP to print unprintable character values
+using the C convention. For example, \f5%#c\fP prints the octal value 012
+as \f5\\n\fP.

+.SH DESCRIPTION
+.PP
+\f5stak\fP is a package of routines designed to provide efficient
+stack oriented dynamic storage.
+A stack abstraction consists of an ordered list of contiguous
+memory regions, called stack frames, that can hold objects of
+arbitrary size.
+A stack is represented by the type \f5Stak_t\fP
+defined in header \f5<stak.h>\fP.
+At any instant there is one active stack.
+Variable size objects can be
+added to the active stack
+and programs can reference these objects directly with pointers.
+In addition, the last object on the stack
+(referred to here as the current object)
+can be built incrementally.
+The current object has an associated offset that determines its
+current size.
+While the current object is being built incrementally,
+its location might
+change so that it is necessary to reference the object with
+relative offsets ranging from zero to the current offset of the object.
+.PP
+There is a preset initial active stack.
+To use an additional stack, it is necessary to create it and to
+install it as the active stack.
+A stack is created with the \f5stakcreate\fP() function.
+A \fIflags\fP argument of \f5STAK_SMALL\fP indicates that unused
+space on the stack should be freed whenever this stack ceases
+to be the active stack. 
+If successful,
+\f5stakcreate\fP() returns a pointer to a stack whose reference
+count is 1.
+Otherwise, \f5stakcreate\fP() returns a null pointer.
+The \f5staklink\fP() function increases the reference count for the
+given \fIstack\fP.
+The \f5stakinstall\fP() function 
+makes the specified \fIstack\fP the active stack and returns a pointer
+to the previous active stack.
+When the \fIoverflow\fP argument is not null,
+it specifies a function that will
+be called whenever \f5malloc\fP(3) fails while trying to grow the
+stack.
+The \fIoverflow\fP function will be called with the size that was passed
+to \f5malloc\fP(3).
+The \fIoverflow\fP function can call \f5exit\fP(3), call \f5longjmp\fP(3)
+or return.
+If the \f5overflow\fP function returns,
+it must return a pointer to a memory region of the given size.
+The default action is to write an error to standard error and to
+call \f5exit\fP(2) with a non-zero exit value.
+When \fIstack\fP is a null pointer,
+the active stack is not changed
+but the \fIoverflow\fP function for the active stack can be changed
+and a pointer to the active stack is returned.
+The \f5stakdelete\fP() function decrements the reference count and
+frees the memory associated with
+the specified stack
+when the reference count is zero.
+The effect of subsequent references to objects
+on the stack are undefined.
+.PP
+The
+\f5stakalloc\fP() function returns an aligned pointer to space on the
+active stack that can be used to hold any object of the given \fIsize\fP.
+\f5stakalloc\fP() is similar to \f5malloc\fP(3) except that individual
+items returned by \f5stakalloc\fP() can not be freed.
+\f5stakalloc\fP() causes the offset of the current object to be set to
+zero.
+.PP
+The
+\f5stakcopy\fP() function copies the given string onto the stack
+and returns a pointer to the \fIstring\fP on the stack.
+\f5stakcopy\fP() causes the offset of the current object to be set to
+zero.
+.PP
+The \f5stakset\fP() function finds the frame containing the given
+\fIaddress\fP, frees all frames that were created after the one containing
+the given \fIaddress\fP, and sets the current object to the given
+\fIaddress\fP.
+The top of the current object is set to \fIoffset\fP bytes from
+current object.
+If \fIaddress\fP is not the address of an object on the
+stack the result is undefined.
+.PP
+The remaining functions are used to build the current object incrementally.
+An object that is built incrementally on the stack will  
+always occupy contiguous memory within a stack frame but
+until \f5stakfreeze\fP() is called,
+the location in memory for the object can change.
+There is a current offset associated with the current object that
+determines where subsequent operations apply.
+Initially, this offset is zero, and the offset changes as a result
+of the operations you specify.
+The \f5stakseek\fP() function is used set the offset for the
+current object.
+The \fIoffset\fP argument to \f5stakseek\fP() specifies the new 
+offset for the current object.
+The frame will be extended or moved
+if \f5offset\fP causes the new current offset to extend beyond the
+current frame.
+\f5stakseek\fP() returns a pointer to the beginning of the current object.
+The \f5staktell\fP() function gives the offset of the current object.
+.PP
+The \f5stakputc\fP() function adds a given character to the current object
+on the stack.
+The current offset is advanced by 1.
+The \f5stakputs\fP() function appends the given \fIstring\fP onto the current
+object in the stack and returns the length of the string.
+The current offset is advanced by the length of the string.
+The \f5stakwrite\fP() function appends the given \fIsize\fP byte memory
+region starting at \fIaddress\fP onto the current
+object in the stack and advances the current offset by \fIsize\fP.
+The current offset is returned.
+.PP
+The \f5stakptr\fP() function converts the given \f5offset\fP
+for the current object into a memory address on the stack.
+This address is only valid until another stack operation is given.
+The result is not defined if \fIoffset\fP exceeds the size of the current
+object.
+The \f5stakfreeze\fP()
+function terminates the current object on the
+stack and returns a pointer to the beginning of this object.
+If \fIextra\fP is non-zero, \fIextra\fP bytes are added to the stack
+before the current object is terminated.  The first added byte will
+contain zero and the contents of the remaining bytes are undefined.
+.PP
+.SH HISTORY
+The
+\f5stak\fP
+interface was derived from similar routines in the KornShell code
+that is used for building parse trees and carrying out expansions.
+It provides an efficient mechanism for grouping dynamically allocated
+objects so that they can be freed all at once rather than individually.

+.L "long streval(char* s, char** e, long (*conv)(char* cs, char** ce))"
+.SH DESCRIPTION
+.I streval
+evaluates the long integer arithmetic expression in the nul-terminated string
+.I s
+and returns the result.
+If
+.I e
+is not 0 then
+.I *e
+is set to point to the first unknown character in the expression.
+.PP
+If
+.I conv
+is not 0 then it is called when an unknown token is encountered in
+.IR s .
+.I cs
+points to the beginning of the unknown token.
+The return value is the long integer value of the unknown token and
+.I ce
+must be set to point to the first character after the unknown token.
+If an expression syntax error is encountered the
+.I conv
+is called with
+.I cs
+set to 0 and
+.I *ce
+pointing to the error message text.
+.PP
+In addition to the normal C expressions and integer constant styles,
+numbers in any base
+.I b
+<= 2 <=36
+may be represented as
+.IR b # nnnn ,
+where the extra digits in
+.I nnnn
+are taken from
+.BR [A-Z] .

+.SH NAME
+tm \- seconds resolution time conversion support
+.SH SYNOPSIS
+.L "#include <tm.h>"
+.SH DESCRIPTION
+The
+.I tm
+library supports conversion between
+string date specifications,
+seconds reolution
+.L time_t
+clock values and
+.LR Tm_t .
+.L Tm_t
+contains the elements of
+.L "struct tm"
+along with these additions:
+.TP
+.L "unsigned _ast_int4_t tm_nsec"
+The subsecond portion of the time in nanoseconds.
+.TP
+.L "Tm_zone_t* tm_zone"
+The time zone name.
+.PP
+.L localtime()
+and
+.L gmtime()
+(see
+.BR ctime (3))
+are used to determine local time zone and savings time information.
+.PP
+.L time_t
+values are the number of seconds since the epoch,
+.BR "Jan 1 00:00:00 GMT 1970" ,
+with leap seconds omitted.
+.PP
+The global variable
+.L "int tm_info.flags"
+contains flags that allow all programs using the library
+to be controlled in a consistent manner.
+.L tm_info.flags
+is initialized by the
+.L tminit()
+routine described below, and may be explicitly reset after
+.L tminit()
+is called.
+The flags are:
+.TP
+.L TM_ADJUST
+Set by
+.L tminit()
+if
+.L localtime()
+and
+.L gmtime()
+do not compensate for leap seconds.
+.TP
+.L TM_LEAP
+.L time_t
+values are interpreted as if they include leap seconds.
+Set by
+.L tminit()
+if the
+.L leap
+option is set in the
+.L TM_OPTIONS
+environment variable.
+.TP
+.L TM_UTC
+Times are relative to
+.B UTC
+(universal coordinated time, i.e.,
+.BR GMT .)
+Otherwise times are relative to the local time zone.
+Set by
+.L tminit()
+if the time zone name matches one of
+.L tm_info.format[43]
+through
+.L tm_info.format[46]
+described below.
+If the time zone name is not determined by
+.L localtime()
+then the environment variables
+.L TZNAME
+(as described in BSD 4.3) and
+.L TZ
+(as described in System V)
+are checked, in order.
+If this fails then the time zone name is constructed using
+the local time zone offset.
+.PP
+The routines are:
+.TP
+.L "time_t tmdate(const char* date, char** end, time_t* clock)"
+Parses the date specification
+.L date
+using the
+.L tm_info.format
+string table (described below)
+and returns the equivalent
+.L time_t
+value.
+If
+.RL non- NULL ,
+.L end
+is set to the position of the first unrecognized character in
+.LR date .
+.L clock
+is used to provide default values for omitted components in
+.LR date .
+If
+.L clock
+is
+.L NULL
+then the current time is used.
+.TP
+.L "Tm_t* tmfix(Tm_t* tp)"
+Corrects any out of bounds fields in
+.L tp
+and returns
+.L tp
+as its value.
+The corrections start with
+.L tp->tm_sec
+and propagate down to
+.LR tp->tm_year .
+For example, if
+.L tp->tm_sec
+were 61 then it would change to 1 and
+.L tp->tm_min
+would be incremented by 1, and so on.
+.L tp->tm_isdst
+is not changed -- call
+.L tmtime()
+to determine its proper value after the
+.L tmfix()
+adjustments.
+.TP
+.L "char* tmfmt(char* buf, size_t len, const char* format, time_t* clock)"
+Formats the date pointed to by
+.L clock
+into the buffer
+.L buf
+with size
+.L len
+bytes according to the format specification
+.LR format .
+If
+.L format
+is
+.L NULL
+or empty then the string
+.L tm_info.format[40]
+is used.
+If
+.L clock
+is
+.L NULL
+then the current time is used.
+A pointer to the end of
+.L buf
+(i.e., the terminating
+.LR "'\e0'" )
+is returned.
+.RS
+.PP
+.L format
+is in
+.BR printf (3)
+style, where
+.RI % field
+names a fixed size field, zero padded if necessary,
+and
+.I \ec
+and
+.I \ennn
+sequences are as in C. Invalid
+.RI % field
+specifications and all other characters are copied
+without change.
+.I field
+may be preceded by
+.B %-
+to turn off padding or
+.B %_
+to pad with space, otherwise numeric fields
+are padded with
+.B 0
+and string fields are padded with space.
+.I field
+may also be preceded by
+.B E
+for alternate era representation or
+.B O
+for alternate digit representation (if supported by the current locale.)
+Finally, an integral
+.I width
+preceding
+.I field
+truncates the field to
+.I width
+characters.
+sequences are interpreted as in the C language.
+String field values are taken from the

+.SH NAME
+tm \- time conversion support
+.SH SYNOPSIS
+.L "#include <tm.h>"
+.SH DESCRIPTION
+The
+.I tm
+library supports conversion between
+string date specifications,
+.L time_t
+clock values and
+.L "struct tm"
+values.
+.L localtime()
+and
+.L gmtime()
+(see
+.IR ctime (3))
+are used to determine local time zone information.
+.PP
+.L time_t
+values are the number of seconds since the epoch,
+.BR "Jan 1 00:00:00 GMT 1970" ,
+with leap seconds omitted.
+.PP
+The global variable
+.L "int tm_info.flags"
+contains flags that allow all programs using the library
+to be controlled in a consistent manner.
+.L tm_info.flags
+is initialized by the
+.L tminit()
+routine described below, and may be explicitly reset after
+.L tminit()
+is called.
+The flags are:
+.TP
+.L TM_ADJUST
+Set by
+.L tminit()
+if
+.L localtime()
+and
+.L gmtime()
+do not compensate for leap seconds.
+.TP
+.L TM_LEAP
+.L time_t
+values are interpreted as if they include leap seconds.
+Set by
+.L tminit()
+if the
+.L leap
+option is set in the
+.L TM_OPTIONS
+environment variable.
+.TP
+.L TM_UTC
+Times are relative to
+.B UTC
+(universal coordinated time, i.e.,
+.BR GMT ).
+Otherwise times are relative to the local time zone.
+Set by
+.L tminit()
+if the time zone name matches one of
+.L tm_info.format[43]
+through
+.L tm_info.format[46]
+described below.
+If the time zone name is not determined by
+.L localtime()
+then the environment variables
+.L TZNAME
+(as described in BSD 4.3) and
+.L TZ
+(as described in System V)
+are checked, in order.
+If this fails then the time zone name is constructed using
+the local time zone offset.
+.PP
+The routines are:
+.TP
+.L "time_t tmdate(const char* date, char** end, time_t* clock)"
+Parses the date specification
+.L date
+using the
+.L tm_info.format
+string table (described below)
+and returns the equivalent
+.L time_t
+value.
+If
+.RL non- NULL ,
+.L end
+is set to the position of the first unrecognized character in
+.LR date .
+.L clock
+is used to provide default values for omitted components in
+.LR date .
+If
+.L clock
+is
+.L NULL
+then the current time is used.
+.TP
+.L "struct tm* tmfix(struct tm* tp)"
+Corrects any out of bounds fields in
+.L tp
+and returns
+.L tp
+as its value.
+The corrections start with
+.L tp->tm_sec
+and propagate down to
+.LR tp->tm_year .
+For example, if
+.L tp->tm_sec
+were 61 then it would change to 1 and
+.L tp->tm_min
+would be incremented by 1, and so on.
+.LR tp->tm_wday ,
+.LR tp->tm_yday
+and
+.L tp->tm_isdst
+are not changed as these can be computed from the other fields.
+.TP
+.L "char* tmfmt(char* buf, size_t len, const char* format, time_t* clock)"
+Formats the date pointed to by
+.L clock
+into the buffer
+.L buf
+with size
+.L len
+bytes according to the format specification
+.LR format .
+If
+.L format
+is
+.L NULL
+or empty then the string
+.L tm_info.format[40]
+is used.
+If
+.L clock
+is
+.L NULL
+then the current time is used.
+A pointer to the end of
+.L buf
+(i.e., the terminating
+.LR "'\e0'" )
+is returned.
+.RS
+.PP
+.L format
+is in the style of
+.IR printf (3),
+where
+.BI % field
+causes the corresponding fixed size field to be placed in
+.LR buf ,
+zero padded if necessary, and \e\fIc\fP and \e\fInnn\fP
+sequences are interpreted as in the C language.
+Otherwise invalid
+.BI % field
+specifications and all other characters in
+.L format
+are copied into
+.L buf
+without change.
+String field values are taken from the
+.L tm_info.format
+string table.
+The
+.I fields
+are:
+.TP
+.PD 0
+.B %
+.B %
+character.

+.L "char* tokread(void* tok)"
+.L "void tokclose(void* tok)"
+.sp
+.L "int tokscan(char* string, char** next, const char* format, ...);"
+.sp
+.L "Sfio_t* tokline(const char* input, int flags, int* line);"
+.SH DESCRIPTION
+.L tokopen
+returns a pointer to a space separated token stream on the 0 terminated
+string
+.LR string .
+.L tokread
+returns a pointer to the next
+space separated token in the token stream
+.L tok
+as returned by
+.LR tokopen .
+0 is returned when no tokens remain.
+.L tokread
+temporarily modifies
+.L string
+by inserting 0's to terminate each token.
+.L tokclose
+closes the token stream and restores
+.L string
+to its original state.
+.PP
+.L tokscan
+scans the string
+.L string
+for tokens specified in
+.LR format .
+It is a more forgiving
+.IR sscanf (3).
+If
+.L "next != 0"
+then it will point to the next unread character in
+.L string
+on return.
+The number of scanned tokens is returned.
+.L \-1
+is returned if 
+.L string
+was not empty and
+.L format
+failed to match and tokens.
+.PP
+.I space
+in
+.L format
+matches 0 or more
+.I space
+or
+.I tab
+characters.
+.I newline
+in format eats the remainder of the current line in
+.LR string .
+"...", '...' and \e\fIcharacter\fP quotes are interpreted.
+A quoted
+.I carriage-return
+is converted to
+.IR newline .
+.I newline
+in
+.L string
+is equivalent to end of string except when quoted.
+.I \enewline
+is a line splice.
+.PP
+.L %
+in
+.L format
+prefixes format conversion characters; each conversion character 
+corresponds to a
+.L tokscan
+argument following the
+.L format
+argument.
+The format conversions are:
+.TP
+.L %c
+A single 
+.LR char .
+.TP
+.L "%hd %d %ld"
+[short, int, long] base 10 integer.
+.TP
+.L "%hn %n %ln"
+[short, int, long] C-style base integer.
+.TP
+.L "%ho %o %lo"
+[short, int, long] base 8 integer.
+.TP
+.L %s
+String.
+.TP
+.L "%hu %u %lu"
+[short, int, long] C-style base unsigned integer.
+.TP
+.L %v
+The next two arguments are a pointer to a
+.L char**
+argument vector and the maximum number of elements in the vector.
+.TP
+.L "%hx %x %lx"
+[short, int, long] base 16 integer.
+.PP
+.L %s
+and
+.L %v
+data may also be counted length strings of the form
+\f5(\fIcount\fP:\fIdata\fP)\fR
+where
+.I count
+is the number of characters in
+.I data
+and the terminating
+.L )
+may also be a
+.IR tab ,
+or the data may be
+.L (null)
+which represents the
+.L NULL
+string.
+.PP
+.L tokline
+returns an
+.IR sfio (3)
+stream to a file or string that splices
+.I \enewline
+into single lines,
+allows "..." and '...' to quotes to span
+.I newlines
+(done by translating quoted
+.I newline
+to
+.IR carriage-return ;
+.L tokscan
+above converts quoted
+.I carriage-return
+back to 
+.IR newline ),
+and deletes
+.I "# ... newline"
+comments.
+This is done by pushing an
+.I sfio
+discipline onto a string or file stream.
+Seeks are disabled on the resulting stream.
+If
+.L "flags == SF_READ"
+then
+.L input
+is a file name;
+If
+.L "flags == SF_STRING"
+then
+.L input
+is a 0 terminated string;
+otherwise
+.L input
+is an open 
+.L Sfio_t*
+stream.
+If
+.L "line != 0"
+then it points to a line count that is initialized to 0
+and is incremented for each input line.

+.SH SYNOPSIS
+.L "#include <tv.h>"
+.SH DESCRIPTION
+The
+.I tv
+library supports high resolution
+.B Tv_t
+time specifications.
+.SS Tv_t
+contains these elements:
+.TP
+.L unsigned
+.L _ast_int4_t
+.L tv_sec
+Seconds since the epoch.
+.TP
+.L unsigned
+.L _ast_int4_t
+.L tv_nsec
+Nanosecond resolution.
+.PP
+In practice resolution is much coarser than 1 nanosecond.
+Systems that only support 1 second resolution always set
+.L tv_nsec
+to 0.
+.SS "int tvgettime(Tv_t* tv)"
+Sets
+.L tv
+to the current time.
+.L 0
+is returned on success,
+.L -1
+on error.
+.SS "int tvsettime(const Tv_t* tv)"
+Sets the system time to
+.LR tv .
+The caller must have sufficient privilege.
+.L 0
+is returned on success,
+.L -1
+on error.
+.SS "int tvcmp(const Tv_t* av, const Tv_t* bv)"
+Compares the times
+.L av
+and
+.L bv
+and returns
+.L -1
+if
+.L av
+is less than
+.LR bv ,
+.L 0
+if
+.L av
+is equal to

+.SS "time_t tvgetmtime(const struct stat* st, Tv_t* tv)"
+.SS "time_t tvgetctime(const struct stat* st, Tv_t* tv)"
+These macros set
+.L tv
+to the

+vecargs \- command argument vector insertion routines
+.SH SYNOPSIS
+.L "#include <vecargs.h>"
+.sp
+.L "char** vecload(char* string);"
+.L "char** vecfile(const char* path);"
+.L "char** vecstring(const char* string);"
+.L "void vecfree(char**, int);"
+.L "int vecargs(char** vec, int* argcp, char*** argvp);"
+.SH DESCRIPTION
+.L vecload
+loads a string vector from lines in
+.LR string .
+.L string
+may be modified upon return.
+Each line in 
+.L string
+is treated as a new vector element.
+Lines with
+.L #
+as the first character are comments.
+.I \enewline
+joins consecutive lines.
+A string vector pointer is returned, 0 on error.
+.PP
+.L vecfile
+constructs a string vector by calling 
+.L vecload 
+on the contents of the file named by
+.LR path .
+The string vector pointer is returned, 0 on error.
+.PP
+.L vecstring
+constructs a string vector by calling 
+.L vecload 
+on a copy of
+.LR string .
+The string vector pointer is returned, 0 on error.
+.PP
+.L vecfree
+frees a string vector allocated by
+.LR vecfile ,
+.L vecload
+or
+.LR vecstring .
+.PP
+.L vecargs
+inserts the string vector
+.L vec
+(as returned by
+.LR vecfile ,
+.L vecload
+or
+.LR vecstring )
+between 
+.L "(*argvp)[0]"
+and
+.LR "(*argvp)[1]" ,
+sliding
+.L "(*argvp)[1] ..."
+over.
+NULL and empty string args in
+.L vec
+are not copied.
+.L "vecfree(vec)"
+is called before the return.
+.L \-1
+is returned if the insertion failed.
+.SH EXAMPLES
+.L vecargs
+is commonly used to modify command 
+.L argv
+from fixed files.
+For example,
+.IR make (1)
+checks for the files
+.L ./Makeargs
+and
+.L ./makeargs
+to modify its arguments on startup.
+Its a handy way to override default options on a directory by directory basis
+without modify the standard control files
+(\f5Makefile\fP in this case.)
+.SH CAVEATS
+This paradigm is not recommended for all commands; only a few exceptions
+make sense.

+.SH DESCRIPTION
+These functions for dynamic storage allocation work in
+\fIregions\fP of memory.
+Each region has an \fIallocation method\fP
+for parceling out blocks of storage and a
+\fImemory discipline\fP for obtaining raw space.
+Automatic locking prevents interference by reentrant
+access to a region.
+.PP
+Pointers to space have type \f5Void_t*\fP
+where \f5Void_t\fP is \f5#define\fPd as \f5void\fP if possible, otherwise \f5char\fP.
+Space is counted in type \f5size_t\fP.
+
+.ne 4
+.SS Regions
+Regions have type \f5Vmalloc_t\fP.
+Two predefined regions are pointed to by:
+.TP
+.MW Vmheap
+A general-purpose region, with best-fit
+allocation, and Unix memory discipline \f5Vmdcsbrk\fP.
+.PP
+These functions manipulate regions:
+.PP
+.I vmopen
+creates a region with memory discipline \fIdisc\fP,
+allocation method \fImeth\fP,
+and a setting for control \fIflags\fP.
+It returns a pointer to the region on success and \f5NULL\fP on failure.
+The flags, represented by bit values or-ed together, are:
+.TP
+.MW VM_TRUST
+Disable locking and consistency checks, except under method \f5Vmdebug\fP.
+.TP
+.MW VM_TRACE
+Place tracing messages for each allocation event
+on the tracing file established by \fIvmtrace\fP.
+This turns off \f5VM_TRUST\fP.
+.TP
+\f5VM_DBCHECK\fP, \f5VM_DBABORT\fP
+.br
+See \fBDebugging\fP below.
+.PP
+.I vmclose
+closes a \fIregion\fP and releases all associated memory
+according to the region's discipline.
+The first segment obtained from the discipline's
+\f5memoryf\fP function (see `Disciplines' below) will be the last released.
+\fIvmclose\fP returns \-1 on failure and a non-negative value otherwise.
+.PP
+.I vmclear
+frees all allocated blocks in \fIregion\fP regardless of methods.
+It returns \-1 on failure and a non-negative value otherwise.
+.PP
+.I vmcompact
+releases as much of a \fIregion\fP's
+free space to its discipline's \f5memoryf\fP
+function as possible.
+It returns a nonnegative value on success and \-1 on failure.
+.PP
+.I vmset
+adjusts and queries a \fIregion\fP's \fIflags\fP.
+The indicated flags are turned on if \fItype\fP is nonzero, off if zero.
+\fIvmset\fP returns the previous value of all flags.
+Thus, \f5vmset(region,0,0)\fP queries the flags without changing them.
+In addition to the settable flags, one of
+\f5VM_MTBEST\fP, \f5VM_MTDEBUG\fP, \f5VM_MTPROFILE\fP,
+\f5VM_MTPOOL\fP, or \f5VM_MTLAST\fP
+is returned to indicate the method used in creating the \fIregion\fP.
+.PP
+.I vmdisc
+changes the discipline of \fIregion\fP to the given new discipline
+\fIdisc\fP if \fIdisc\fP is not \f5NULL\fP and its \f5memoryf\fP function
+is the same as the current discipline. If the current discipline
+has an \f5exceptf\fP function, it will be called with event \f5VM_DISC\fP.
+This function always returns the current discipline.
+.PP
+.I vmmopen
+creates a region to allocate memory given by the system call \fImmap(2)\fP.
+The given \fIfile\fP is the backing store for the map.
+If \fIbase\fP is not \f5NULL\fP, it is the address to map the data to.
+The \fIround\fP argument asserts that the size of the region is always
+a multiple of this value. However, note that \fIvmmopen\fP has
+an internally defined minimum round value (typically 64K) which may be
+used if the given value is too small.
+.PP
+.I vmmset
+sets a \fIdata\fP value associated with a \fIkey\fP if \f5set\fP is non-zero.
+In this case, it returns the current data (before setting)
+if \fIkey\fP is previously set; otherwise, it returns the new \fIdata\fP value.
+If the argument \fIset\fP is zero,
+the call returns the current data value associated with \fIkey\fP, if any.
+
+.SS "Allocation functions"
+.I vmalloc
+returns a pointer to a block of the requested \fIsize\fP
+in a \fIregion\fP, aligned to the \fIstrictest alignment\fP
+that is suitable for the needs of any basic data type.
+It returns \f5NULL\fP on failure.
+.PP
+.I vmalign
+works like \fIvmalloc\fP, but returns a block aligned to a common
+multiple of \fIalign\fP and the \fIstrictest alignment\fP.
+.PP
+.I vmresize
+attempts to change the length of the block pointed to by
+\fIaddr\fP to the specified \fIsize\fP.
+If that is impossible and \fItype\fP has
+at least one of \f5VM_RSMOVE\fP and \f5VM_RSCOPY\fP,
+a new block is allocated and the old block is freed.
+The bit \f5VM_RSCOPY\fP also causes
+the new block to be initialized with
+as much of the old contents as will fit.
+When a resized block gets larger, the new space will be cleared
+if \fItype\fP has the bit \f5VM_RSZERO\fP.
+\fIvmresize\fP
+returns a pointer to the final block, or \f5NULL\fP on failure.
+If \fIaddr\fP is \f5NULL\fP, \fIvmresize\fP behaves like \fIvmalloc\fP;
+otherwise, if \fIsize\fP is 0, it behaves like \fIvmfree\fP.
+.PP
+.I vmfree
+makes the currently allocated block pointed to by
+\fIaddr\fP available for future allocations in its \fIregion\fP.
+If \fIaddr\fP is \f5NULL\fP, \fIvmfree\fP does nothing.
+It returns \-1 on error, and nonnegative otherwise.
+.PP
+.I vmnewof
+is a macro function that attempts to change the length of
+the block pointed to by \fIaddr\fP to the size \f5n*sizeof(type)+x\fP.
+If the block is moved, new space will be initialized with as much of the
+old content as will fit.
+Additional space will be set to zero.
+.PP
+.I vmoldof
+is similar to \fIvmnewof\fP but it neither copies data nor clears space.
+.PP
+.I vmgetmem
+provides a handy function to creat/close regions and allocate/free memory
+based on chunks of memory obtained from the heap region \fIVmheap\fP.
+.TP
+.MW "vmgetmem(0,0,0)"
+This call opens a new region.
+.TP
+.MW "vmgetmem(region, 0, 0)"
+This call closes the given \f5region\fP.
+.TP
+.MW "vmgetmem(region,0,n)"
+This call allocates a block of length \f5n\fP and clears it to zeros.
+.TP
+.MW "vmgetmem(region,p,0)"
+This call frees the block \f5p\fP.
+.TP
+.MW "vmgetmem(region,p,n)"
+This call resizes the block \f5p\fP to length \f5n\fP
+and clears the new memory to zeros if the block grows.
+The block may be moved as deemed necessary by the allocator.
+.PP
+.SS "Memory disciplines"
+Memory disciplines have type \f5Vmdisc_t\fP,
+a structure with these members:
+.in +.5i
+.nf
+.MW "Void_t* (*memoryf)(Vmalloc_t *region, Void_t* obj,"
+.ti +.5i
+.MW "size_t csz, size_t nsz, Vmdisc_t *disc);"
+.MW "int (*exceptf)(Vmalloc_t *region, int type, Void_t* obj, Vmdisc_t *disc);"
+.MW "int round;"
+.fi
+.in -.5i
+.TP
+.MW round 
+If this value is positive, all size arguments to the
+\f5memoryf\fP function will be multiples of it.
+.TP
+.MW memoryf
+Points to a function to get or release segments of space for the
+\fIregion\fP.
+.TP
+.MW exceptf
+If this pointer is not \f5NULL\fP,
+the function it points to is called to announce
+events in a \fIregion\fP.
+.PP
+There are two standard disciplines.
+In both,
+\f5round\fP is 0, and \f5exceptf\fP is \f5NULL\fP.
+.TP
+.MW Vmdcsbrk
+A discipline whose \f5memoryf\fP function gets space from \fIsbrk\fP(2).
+.br
+.ns
+.TP
+.MW Vmdcheap
+A discipline whose \f5memoryf\fP function gets space from the region \f5Vmheap\fP.
+A region with \f5Vmdcheap\fP discipline and \f5Vmlast\fP
+allocation is good for building throwaway data structures.
+.PP
+A \fImemoryf\fP
+function returns a pointer to a memory segment on success, and \f5NULL\fP on failure.
+If \fIcsz\fP is 0, the function returns a new segment of size \fInsz\fP.
+Otherwise, the function attempts to change the length of the segment
+pointed to by \fIaddr\fP from \fIcsz\fP to \fInsz\fP.
+If this is successful, \f5memoryf\fP should return \fIaddr\fP (even if \fInsz\fP is 0).
+.PP
+An \fIexceptf\fP
+function is called for events identified by \fItype\fP, which is coded thus:
+.TP
+.MW VM_OPEN
+A new region is being opened.
+If \fIexceptf\fP returns a zero value, the region opening proceeds normally.
+A negative return value causes \fIvmopen\fP to terminate with failure.
+A positive return value indicates that the new region is to manipulate memory
+already initialized by a previous \fIvmopen\fP call
+(perhaps by a different process on persistent or shared memory).
+In this case, the argument \f5(Void_t**)\fP\fIobj\fP should
+return the initial segment (which is of type \f5(Void_t*)\fP).
+\fIvmopen\fP will return failure if this segment is not returned or if it
+has not been properly initialized.
+.TP
+.MW VM_CLOSE
+The region is being closed.
+The return value of \f5exceptf\fP is significant as follows.
+If negative, \fIvmclose\fP immediately returns with failure.
+If zero, \fIvmclose\fP proceeds normally by calling \f5memoryf\fP to free
+all allocated memory segments and also freeing the region itself.
+Finally, if positive, \fIvmclose\fP will only free the region
+without deallocating the allocated segments.
+.TP
+.MW VM_NOMEM
+An attempt to extend the region by the amount
+\f5(size_t)\fP\fIobj\fP failed. The region is unlocked, so the
+\fIexceptf\fP function may free blocks.
+If the function returns a positive value the memory
+request will be repeated.
+If zero, the allocation method
+will again invoke \fImemoryf\fP to get space.
+If negative, the allocation request will fail.
+.TP
+.MW VM_BADADDR
+Address \fIobj\fP, given to \fIvmfree\fP or \fIvmresize\fP,
+does not point to an allocated block from the region.
+The respective call will fail.
+.TP
+.MW VM_ALLOC
+Announce that a memory allocation request is finished and returning.
+.TP
+.MW VM_FREE
+Announce that a memory freeing request is finished and returning.
+.TP
+.MW VM_RESIZE
+Announce that a memory resizing request is finished and returning.
+
+.SS "Allocation methods"
+There are five methods, of type \f5Vmethod_t*\fP:
+.TP
+.MW Vmbest
+An approximately best-fit allocation strategy.
+.TP
+.MW Vmlast
+A strategy for building structures that are only deleted in whole.
+Only the latest allocated block can be freed.
+This means that as soon as a block \f5a\fP is allocated,
+\fIvmfree\fP calls on blocks other than \c5a\fP are ignored.
+.TP
+.MW Vmpool
+A strategy for blocks of one size,
+set by the first \fIvmalloc\fP call after \fIvmopen\fP or \fIvmclear\fP.
+.TP
+.MW Vmdebug
+An allocation strategy with extra-stringent checking and locking
+regardless of the \f5VM_TRUST\fP flag.
+It is useful for finding misuses of dynamically allocated
+memory, such as writing beyond the boundary of a block, or
+freeing a block twice.
+.ne 3
+.TP
+.MW Vmprofile
+An allocation method that records and prints summaries of memory usage.
+
+.SS Debugging
+The method \f5Vmdebug\fP is used to debug common memory violation problems.
+When a problem is found,
+a warning message is written to file descriptor 2 (standard error).
+In addition, if flag \f5VM_DBABORT\fP is on,
+the program is terminated by calling \fIabort\fP(2).
+Each message is a line of self-explanatory fields separated by colons.
+The optional flag \f5-DVMFL\fP, if used during compilation,
+enables recording of file names and line numbers.
+The following functions work with method \f5Vmdebug\fP.
+.PP
+.I vmdebug
+resets the file descriptor to write out warnings to the given argument.
+By default, this file descriptor is 2, the standard error.
+\fIvmdebug\fP returns the previous file descriptor.
+.PP
+.I vmdbcheck
+checks a region using \f5Vmdebug\fP or \f5Vmbest\fP for integrity.
+If \f5Vmdebug\fP, this also checks for block overwriting errors.
+On errors, \fIvmdbwarn\fP is called.
+If flag \f5VM_DBCHECK\fP is on, 
+\fIvmdbcheck\fP is called at each invocation of
+\fIvmalloc\fP, \fIvmfree\fP, or \fIvmresize\fP.
+.PP
+.I vmdbwatch
+causes address \fIaddr\fP
+to be watched, and reported whenever met in
+\fIvmalloc\fP, \fIvmresize\fP or \fIvmfree\fP.
+The watch list has finite size and if it becomes full,
+watches will be removed in a first-in-first-out fashion.
+If \fIaddr\fP is \f5NULL\fP,
+all current watches are canceled.
+\fIvmdbwatch\fP returns the watch bumped out due to an insertion
+into a full list or \f5NULL\fP otherwise.
+.PP
+.I vmdbwarn
+is an internal function that processes
+warning messages for discovered errors.
+It can't be called from outside the \fIvmalloc\fP package,
+but is a good place to plant debugger traps because
+control goes there at every trouble.
+
+.SS "Profiling"
+The method \f5Vmprofile\fP is used to profile memory usage.
+Profiling data are maintained in private memory of a process so
+\f5Vmprofile\fP should be avoided from regions manipulating
+persistent or shared memory.
+The optional flag \f5-DVMFL\fP, if used during compilation,
+enables recording of file names and line numbers.
+.PP
+.I vmprofile
+prints memory usage summary.
+The summary is restricted to region \fIvm\fP if \fIvm\fP is not \f5NULL\fP;
+otherwise, it is for all regions created with \f5Vmprofile\fP.
+Summary records are written to file descriptor \fIfd\fP as lines with
+colon-separated fields. Here are some of the fields:
+.TP
+.I n_alloc,n_free:
+Number of allocation and free calls respectively. Note that a resize
+operation is coded as a free and an allocation.
+.TP
+.I s_alloc,s_free:
+Total amounts allocated and freed. The difference between these numbers
+is the amount of space not yet freed.
+.TP
+.I max_busy, extent:
+These fields are only with the summary record for region.
+They show the maximum busy space at any time and the extent of the region.
+
+.SS "Information and statistics"
+.I vmregion
+returns the region to which the block pointed to by
+\fIaddr\fP belongs.
+This works only in regions that allocate with
+\f5Vmbest\fP, \f5Vmdebug\fP or \f5Vmprofile\fP.
+If multiple regions manipulate the same segment of memory,
+\fIvmregion\fP returns the region that causes the creation that memory segment.
+.PP
+.I vmsegment
+finds if some segment of memory in \fIregion\fP
+contains the address \fIaddr\fP.
+It returns the address of a found segment or \f5NULL\fP if none found.
+.PP
+.I vmwalk
+walks all segments in \fIregion\fP or if \fIregion\fP is \f5NULL\fP,
+all segments in all regions.
+At each segment, \fI(*walkf)(vm,addr,size,disc)\fP
+is called where \fIvm\fP is the region, \fIaddr\fP is the segment,
+\fIsize\fP is the size of the segment, and \fIdisc\fP is the region's discipline.
+If \fIwalkf\fP returns a negative value, the walk stops and returns the same value.
+On success, \fIvmwalk\fP returns 0; otherwise, it returns \-1.
+.PP
+.I vmaddr
+checks whether \fIaddr\fP
+points to an address within some allocated block of the given region.
+If not, it returns \-1.
+If so, it returns the offset from the beginning of the block.
+The function does not work for a \f5Vmlast\fP region except
+on the latest allocated block.
+.PP
+.I vmsize
+returns the size of the allocated block pointed to by \fIaddr\fP.
+It returns \-1 if \fIaddr\fP
+does not point to a valid block in the region.
+Sizes may be padded beyond that requested; in
+particular no block has size 0.
+The function does not work for a \f5Vmlast\fP region except
+on the latest allocated block.
+.PP
+.I vmstat
+gathers statistics on the given \fIregion\fP and returns that
+information in the \f5Vmstat_t\fP structure pointed to by \fIstatb\fP.
+A \f5Vmstat_t\fP structure has at least these members:
+.in +.5i
+.nf
+.ta \w'\f5size_t  \fP'u +\w'\f5extent    \fP'u
+.MW "int	n_busy;	/* number of busy blocks */
+.MW "int	n_free;	/* number of free blocks */
+.MW "size_t	s_busy;	/* total busy space */
+.MW "size_t	s_free;	/* total free space */
+.MW "size_t	m_busy;	/* maximum size of busy block */
+.MW "size_t	m_free;	/* maximum size of free block */
+.MW "int	n_seg;	/* number of segments in region */
+.MW "size_t	extent;	/* total size of the region */
+.fi
+.in -.5i
+.PP
+Bookeeping overhead is counted in \f5extent\fP,
+but not in \f5s_busy\fP or \f5s_free\fP.
+.PP
+.I vmtrace
+establishes file descriptor \fIfd\fP
+as the trace file and returns
+the previous value of the trace file descriptor.
+The trace descriptor is initially invalid.
+Output is sent to the trace file by successful allocation
+events when flag \f5VM_TRACE\fP is on.
+.PP
+Tools for analyzing traces are described in \fImtreplay\fP(1).
+The trace record for an allocation event
+is a line with colon-separated fields, four numbers and one string.
+.TP
+.I old
+Zero for a fresh allocation;
+the address argument for freeing and resizing.
+.TP
+.I new
+Zero for freeing;
+the address returned by allocation or resizing.
+.TP
+.I size
+The size argument for allocation or resizing;
+the size freed by freeing.
+Sizes may differ due to padding for alignment.
+.TP
+.I region
+The address of the affected region.
+.TP
+.I method
+A string that tells the region's method:
+\f5best\fP, \f5last\fP, \f5pool\fP, \f5profile\fP, or \f5debug\fP.
+.PP
+.I vmtrbusy
+outputs a trace of all currently busy blocks in region \f5vm\fP.
+This only works with the \f5Vmbest\fP, \f5Vmdebug\fP and \f5Vmprofile\fP methods.
+
+.SS "Malloc-compatible functions"
+Functions in this set provide the behaviors of \fImalloc\fP(3).
+The functions
+\fImemalign\fP and \fIvalloc\fP allocate aligned blocks;
+\fIvalloc\fP further restricts alignment to page boundaries.
+.PP
+The \fImalloc\fP functions are instrumented for run-time debugging,
+profiling and tracing.
+When these modes are enable, time and space performance will be affected.
+For accurate reporting of files and line numbers,
+code should include \f5vmalloc.h\fP and compile with \f5-DVMFL\fP.
+
+The following environment variables should be set before any memory allocation
+(e.g., before a process starts). They drive different modes:
+.TP
+.I VMETHOD
+This defines the method to use for allocation.
+Its value should be one of the strings:
+\fIVmbest, Vmdebug, Vmprofile, Vmlast, Vmpool\fP.
+The 'V' can be in lower case.
+.TP
+.I VMDEBUG
+This is ignored if
+a method other than \f5Vmdebug\fP has been selected with \fIVMETHOD\fP.
+\fIVMDEBUG\fP can be any combination of `a',
+a decimal number and a list of hexadecimal numbers.
+`a' causes the program to abort on any discovered allocation error.
+A hexadecimal number starts with either \fI0x\fP or \fI0X\fP
+and defines an address to watch (see \fIvmdbwatch\fP).
+Any other number is taken to be decimal and defines a period \fIp\fP
+to check the arena for integrity. The default period is 1, ie, the
+arena is checked on every call to a \fImalloc\fP function.
+Other letters not part of the defined set are ignored.
+.TP
+.I VMPROFILE
+This is ignored if a method other than \f5Vmprofile\fP
+has been selected by \fIVMETHOD\fP or \fIVMDEBUG\fP.
+\fIVMPROFILE\fP defines a file name to store profile data.
+Each instance of the pattern `%p' found in \fIVMPROFILE\fP
+is transformed to the process id of the running process.
+If the file cannot be created, file descriptor 2 (standard error)
+is used for output.
+.TP
+.I VMTRACE
+If this defines a valid writable file, trace messages of all allocation calls
+are written to the given file (see \fIvmopen()\fP and \fIvmtrace()\fP).
+Similar to \fIVMPROFILE\fP, each instance of the pattern `%p' found
+in \fIVMTRACE\fP is turned to the process id of the running process.
+

+ * space by a factor of 4-5, bigram coding by a further 20-25%.
+ *
+ * there are 4 methods:
+ *
+ *	FF_old	original with 7 bit bigram encoding (no magic)
+ *	FF_gnu	8 bit clean front compression (FF_gnu_magic)
+ *	FF_dir	FF_gnu with sfgetl/sfputl and trailing / on dirs (FF_dir_magic)
+ *	FF_typ	FF_dir with (mime) types (FF_typ_magic)
+ *
+ * the bigram encoding steals the eighth bit (that's why its FF_old)
+ * maybe one day we'll limit it to readonly:
+ *
+ * 0-2*FF_OFF	 likeliest differential counts + offset to make nonnegative 
+ * FF_ESC	 4 byte big-endian out-of-range count+FF_OFF follows
+ * FF_MIN-FF_MAX ascii residue
+ * >=FF_MAX	 bigram codes
+ *
+ * a two-tiered string search technique is employed
+ *
+ * a metacharacter-free subpattern and partial pathname is matched
+ * backwards to avoid full expansion of the pathname list
+ *
+ * then the actual shell glob-style regular expression (if in this form)

+**
+**	When the application fills or flushes the stream buffer, data
+**	will be processed through discipline functions. A case deserving
+**	consideration is stacking a discipline onto a read stream. Each
+**	discipline operation implies buffer synchronization so the stream
+**	buffer should be empty. However, a read stream representing an
+**	unseekable device (eg, a pipe) may not be synchronizable. In that
+**	case, any buffered data must then be fed to the new discipline
+**	to preserve data processing semantics. This is done by creating
+**	a temporary discipline to cache such buffered data and feed
+**	them to the new discipline when its readf() asks for new data.
+**	Care must then be taken to remove this temporary discipline
+**	when it runs out of cached data.

+ * if m>1 and no multipler was specified then the result is multiplied by m
+ * if m<0 then multipliers are not consumed
+ * if a base arg or prefix is specified then multiplier is not consumed

+
+/*
+ * Cipher-block representation (Bob Baldwin):
+ *
+ * DES operates on groups of 64 bits, numbered 1..64 (sigh).  One
+ * representation is to store one bit per byte in an array of bytes.  Bit N of
+ * the NBS spec is stored as the LSB of the Nth byte (index N-1) in the array.
+ * Another representation stores the 64 bits in 8 bytes, with bits 1..8 in the
+ * first byte, 9..16 in the second, and so on.  The DES spec apparently has
+ * bit 1 in the MSB of the first byte, but that is particularly noxious so we
+ * bit-reverse each byte so that bit 1 is the LSB of the first byte, bit 8 is
+ * the MSB of the first byte.  Specifically, the 64-bit input data and key are
+ * converted to LSB format, and the output 64-bit block is converted back into
+ * MSB format.
+ *
+ * DES operates internally on groups of 32 bits which are expanded to 48 bits
+ * by permutation E and shrunk back to 32 bits by the S boxes.  To speed up
+ * the computation, the expansion is applied only once, the expanded
+ * representation is maintained during the encryption, and a compression
+ * permutation is applied only at the end.  To speed up the S-box lookups,
+ * the 48 bits are maintained as eight 6 bit groups, one per byte, which
+ * directly feed the eight S-boxes.  Within each byte, the 6 bits are the
+ * most significant ones.  The low two bits of each byte are zero.  (Thus,
+ * bit 1 of the 48 bit E expansion is stored as the "4"-valued bit of the
+ * first byte in the eight byte representation, bit 2 of the 48 bit value is
+ * the "8"-valued bit, and so on.)  In fact, a combined "SPE"-box lookup is
+ * used, in which the output is the 64 bit result of an S-box lookup which
+ * has been permuted by P and expanded by E, and is ready for use in the next
+ * iteration.  Two 32-bit wide tables, SPE[0] and SPE[1], are used for this
+ * lookup.  Since each byte in the 48 bit path is a multiple of four, indexed
+ * lookup of SPE[0] and SPE[1] is simple and fast.  The key schedule and
+ * "salt" are also converted to this 8*(6+2) format.  The SPE table size is
+ * 8*64*8 = 4K bytes.
+ *
+ * To speed up bit-parallel operations (such as XOR), the 8 byte
+ * representation is "union"ed with 32 bit values "i0" and "i1", and, on
+ * machines which support it, a 64 bit value "b64".  This data structure,
+ * "C_block", has two problems.  First, alignment restrictions must be
+ * honored.  Second, the byte-order (e.g. little-endian or big-endian) of
+ * the architecture becomes visible.
+ *
+ * The byte-order problem is unfortunate, since on the one hand it is good
+ * to have a machine-independent C_block representation (bits 1..8 in the
+ * first byte, etc.), and on the other hand it is good for the LSB of the
+ * first byte to be the LSB of i0.  We cannot have both these things, so we
+ * currently use the "little-endian" representation and avoid any multi-byte
+ * operations that depend on byte order.  This largely precludes use of the
+ * 64-bit datatype since the relative order of i0 and i1 are unknown.  It
+ * also inhibits grouping the SPE table to look up 12 bits at a time.  (The
+ * 12 bits can be stored in a 16-bit field with 3 low-order zeroes and 1
+ * high-order zero, providing fast indexing into a 64-bit wide SPE.)  On the
+ * other hand, 64-bit datatypes are currently rare, and a 12-bit SPE lookup
+ * requires a 128 kilobyte table, so perhaps this is not a big loss.
+ *
+ * Permutation representation (Jim Gillogly):
+ *
+ * A transformation is defined by its effect on each of the 8 bytes of the
+ * 64-bit input.  For each byte we give a 64-bit output that has the bits in
+ * the input distributed appropriately.  The transformation is then the OR
+ * of the 8 sets of 64-bits.  This uses 8*256*8 = 16K bytes of storage for
+ * each transformation.  Unless LARGEDATA is defined, however, a more compact
+ * table is used which looks up 16 4-bit "chunks" rather than 8 8-bit chunks.
+ * The smaller table uses 16*16*8 = 2K bytes for each transformation.  This
+ * is slower but tolerable, particularly for password encryption in which
+ * the SPE transformation is iterated many times.  The small tables total 9K
+ * bytes, the large tables total 72K bytes.
+ *
+ * The transformations used are:
+ * IE3264: MSB->LSB conversion, initial permutation, and expansion.
+ *	This is done by collecting the 32 even-numbered bits and applying
+ *	a 32->64 bit transformation, and then collecting the 32 odd-numbered
+ *	bits and applying the same transformation.  Since there are only
+ *	32 input bits, the IE3264 transformation table is half the size of
+ *	the usual table.
+ * CF6464: Compression, final permutation, and LSB->MSB conversion.
+ *	This is done by two trivial 48->32 bit compressions to obtain
+ *	a 64-bit block (the bit numbering is given in the "CIFP" table)
+ *	followed by a 64->64 bit "cleanup" transformation.  (It would
+ *	be possible to group the bits in the 64-bit block so that 2
+ *	identical 32->32 bit transformations could be used instead,
+ *	saving a factor of 4 in space and possibly 2 in time, but
+ *	byte-ordering and other complications rear their ugly head.
+ *	Similar opportunities/problems arise in the key schedule
+ *	transforms.)
+ * PC1ROT: MSB->LSB, PC1 permutation, rotate, and PC2 permutation.
+ *	This admittedly baroque 64->64 bit transformation is used to
+ *	produce the first code (in 8*(6+2) format) of the key schedule.
+ * PC2ROT[0]: Inverse PC2 permutation, rotate, and PC2 permutation.
+ *	It would be possible to define 15 more transformations, each
+ *	with a different rotation, to generate the entire key schedule.
+ *	To save space, however, we instead permute each code into the
+ *	next by using a transformation that "undoes" the PC2 permutation,
+ *	rotates the code, and then applies PC2.  Unfortunately, PC2
+ *	transforms 56 bits into 48 bits, dropping 8 bits, so PC2 is not
+ *	invertible.  We get around that problem by using a modified PC2
+ *	which retains the 8 otherwise-lost bits in the unused low-order
+ *	bits of each byte.  The low-order bits are cleared when the
+ *	codes are stored into the key schedule.
+ * PC2ROT[1]: Same as PC2ROT[0], but with two rotations.
+ *	This is faster than applying PC2ROT[0] twice,
+ *
+ * The Bell Labs "salt" (Bob Baldwin):
+ *
+ * The salting is a simple permutation applied to the 48-bit result of E.
+ * Specifically, if bit i (1 <= i <= 24) of the salt is set then bits i and
+ * i+24 of the result are swapped.  The salt is thus a 24 bit number, with
+ * 16777216 possible values.  (The original salt was 12 bits and could not
+ * swap bits 13..24 with 36..48.)
+ *
+ * It is possible, but ugly, to warp the SPE table to account for the salt
+ * permutation.  Fortunately, the conditional bit swapping requires only
+ * about four machine instructions and can be done on-the-fly with about an
+ * 8% performance penalty.

+ *                  = 0.5 + ((0.5-x)-x*P)  if x in [0.25,0.84375]
+ *	   where
+ *			2		 2	  4		  20  
+ *              P =  P(x ) = (p0 + p1 * x + p2 * x + ... + p10 * x  )
+ * 	   is an approximation to (erf(x)-x)/x with precision
+ *
+ *						 -56.45
+ *			| P - (erf(x)-x)/x | <= 2
+ *	
+ *
+ *	   Remark. The formula is derived by noting
+ *          erf(x) = (2/sqrt(pi))*(x - x^3/3 + x^5/10 - x^7/42 + ....)
+ *	   and that
+ *          2/sqrt(pi) = 1.128379167095512573896158903121545171688
+ *	   is close to one. The interval is chosen because the fixed
+ *	   point of erf(x) is near 0.6174 (i.e., erf(x)=x when x is
+ *	   near 0.6174), and by some experiment, 0.84375 is chosen to
+ * 	   guarantee the error is less than one ulp for erf.
+ *
+ *      3. For x in [0.84375,1.25], let s = x - 1, and
+ *         c = 0.84506291151 rounded to single (24 bits)
+ *         	erf(x)  = c  + P1(s)/Q1(s)
+ *         	erfc(x) = (1-c)  - P1(s)/Q1(s)
+ *         	|P1/Q1 - (erf(x)-c)| <= 2**-59.06
+ *	   Remark: here we use the taylor series expansion at x=1.
+ *		erf(1+s) = erf(1) + s*Poly(s)
+ *			 = 0.845.. + P1(s)/Q1(s)
+ *	   That is, we use rational approximation to approximate
+ *			erf(1+s) - (c = (single)0.84506291151)
+ *	   Note that |P1/Q1|< 0.078 for x in [0.84375,1.25]
+ *	   where 
+ *		P1(s) = degree 6 poly in s
+ *		Q1(s) = degree 6 poly in s
+ *
+ *	4. For x in [1.25, 2]; [2, 4]
+ *         	erf(x)  = 1.0 - tiny
+ *		erfc(x)	= (1/x)exp(-x*x-(.5*log(pi) -.5z + R(z)/S(z))
+ *
+ *	Where z = 1/(x*x), R is degree 9, and S is degree 3;
+ *	
+ *      5. For x in [4,28]
+ *         	erf(x)  = 1.0 - tiny
+ *		erfc(x)	= (1/x)exp(-x*x-(.5*log(pi)+eps + zP(z))
+ *
+ *	Where P is degree 14 polynomial in 1/(x*x).
+ *
+ *      Notes:
+ *	   Here 4 and 5 make use of the asymptotic series
+ *			  exp(-x*x)
+ *		erfc(x) ~ ---------- * ( 1 + Poly(1/x^2) );
+ *			  x*sqrt(pi)
+ *
+ *		where for z = 1/(x*x)
+ *		P(z) ~ z/2*(-1 + z*3/2*(1 + z*5/2*(-1 + z*7/2*(1 +...))))
+ *
+ *	   Thus we use rational approximation to approximate
+ *              erfc*x*exp(x*x) ~ 1/sqrt(pi);
+ *
+ *		The error bound for the target function, G(z) for
+ *		the interval
+ *		[4, 28]:
+ * 		|eps + 1/(z)P(z) - G(z)| < 2**(-56.61)
+ *		for [2, 4]:
+ *      	|R(z)/S(z) - G(z)|	 < 2**(-58.24)
+ *		for [1.25, 2]:
+ *		|R(z)/S(z) - G(z)|	 < 2**(-58.12)
+ *
+ *      6. For inf > x >= 28
+ *         	erf(x)  = 1 - tiny  (raise inexact)
+ *         	erfc(x) = tiny*tiny (raise underflow)
+ *
+ *      7. Special cases:
+ *         	erf(0)  = 0, erf(inf)  = 1, erf(-inf) = -1,
+ *         	erfc(0) = 1, erfc(inf) = 0, erfc(-inf) = 2, 
+ *	   	erfc/erf(NaN) is NaN

+/* EXPM1(X)
+ * RETURN THE EXPONENTIAL OF X MINUS ONE
+ * DOUBLE PRECISION (IEEE 53 BITS, VAX D FORMAT 56 BITS)
+ * CODED IN C BY K.C. NG, 1/19/85; 
+ * REVISED BY K.C. NG on 2/6/85, 3/7/85, 3/21/85, 4/16/85.
+ *
+ * Required system supported functions:
+ *	scalb(x,n)	
+ *	copysign(x,y)	
+ *	finite(x)
+ *
+ * Kernel function:
+ *	exp__E(x,c)
+ *
+ * Method:
+ *	1. Argument Reduction: given the input x, find r and integer k such 
+ *	   that
+ *	                   x = k*ln2 + r,  |r| <= 0.5*ln2 .  
+ *	   r will be represented as r := z+c for better accuracy.
+ *
+ *	2. Compute EXPM1(r)=exp(r)-1 by 
+ *
+ *			EXPM1(r=z+c) := z + exp__E(z,c)
+ *
+ *	3. EXPM1(x) =  2^k * ( EXPM1(r) + 1-2^-k ).
+ *
+ * 	Remarks: 
+ *	   1. When k=1 and z < -0.25, we use the following formula for
+ *	      better accuracy:
+ *			EXPM1(x) = 2 * ( (z+0.5) + exp__E(z,c) )
+ *	   2. To avoid rounding error in 1-2^-k where k is large, we use
+ *			EXPM1(x) = 2^k * { [z+(exp__E(z,c)-2^-k )] + 1 }
+ *	      when k>56. 
+ *
+ * Special cases:
+ *	EXPM1(INF) is INF, EXPM1(NaN) is NaN;
+ *	EXPM1(-INF)= -1;
+ *	for finite argument, only EXPM1(0)=0 is exact.
+ *
+ * Accuracy:
+ *	EXPM1(x) returns the exact (exp(x)-1) nearly rounded. In a test run with
+ *	1,166,000 random arguments on a VAX, the maximum observed error was
+ *	.872 ulps (units of the last place).
+ *
+ * Constants:
+ * The hexadecimal values are the intended ones for the following constants.
+ * The decimal values may be used, provided that the compiler will convert
+ * from decimal to binary accurately enough to produce the hexadecimal values
+ * shown.

+/* Table-driven natural logarithm.
+ *
+ * This code was derived, with minor modifications, from:
+ *	Peter Tang, "Table-Driven Implementation of the
+ *	Logarithm in IEEE Floating-Point arithmetic." ACM Trans.
+ *	Math Software, vol 16. no 4, pp 378-400, Dec 1990).
+ *
+ * Calculates log(2^m*F*(1+f/F)), |f/j| <= 1/256,
+ * where F = j/128 for j an integer in [0, 128].
+ *
+ * log(2^m) = log2_hi*m + log2_tail*m
+ * since m is an integer, the dominant term is exact.
+ * m has at most 10 digits (for subnormal numbers),
+ * and log2_hi has 11 trailing zero bits.
+ *
+ * log(F) = logF_hi[j] + logF_lo[j] is in tabular form in log_table.h
+ * logF_hi[] + 512 is exact.
+ *
+ * log(1+f/F) = 2*f/(2*F + f) + 1/12 * (2*f/(2*F + f))**3 + ...
+ * the leading term is calculated to extra precision in two
+ * parts, the larger of which adds exactly to the dominant
+ * m and F terms.
+ * There are two cases:
+ *	1. when m, j are non-zero (m | j), use absolute
+ *	   precision for the leading term.
+ *	2. when m = j = 0, |1-x| < 1/256, and log(x) ~= (x-1).
+ *	   In this case, use a relative precision of 24 bits.
+ * (This is done differently in the original paper)
+ *
+ * Special cases:
+ *	0	return signalling -Inf
+ *	neg	return signalling NaN
+ *	+Inf	return +Inf

+ * RETURN THE LOGARITHM OF 1+x
+ * DOUBLE PRECISION (VAX D FORMAT 56 bits, IEEE DOUBLE 53 BITS)
+ * CODED IN C BY K.C. NG, 1/19/85; 
+ * REVISED BY K.C. NG on 2/6/85, 3/7/85, 3/24/85, 4/16/85.
+ * 
+ * Required system supported functions:
+ *	scalb(x,n) 
+ *	copysign(x,y)
+ *	logb(x)	
+ *	finite(x)
+ *
+ * Required kernel function:
+ *	log__L(z)
+ *
+ * Method :
+ *	1. Argument Reduction: find k and f such that 
+ *			1+x  = 2^k * (1+f), 
+ *	   where  sqrt(2)/2 < 1+f < sqrt(2) .
+ *
+ *	2. Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
+ *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
+ *	   log(1+f) is computed by
+ *
+ *	     		log(1+f) = 2s + s*log__L(s*s)
+ *	   where
+ *		log__L(z) = z*(L1 + z*(L2 + z*(... (L6 + z*L7)...)))
+ *
+ *	   See log__L() for the values of the coefficients.
+ *
+ *	3. Finally,  log(1+x) = k*ln2 + log(1+f).  
+ *
+ *	Remarks 1. In step 3 n*ln2 will be stored in two floating point numbers
+ *		   n*ln2hi + n*ln2lo, where ln2hi is chosen such that the last 
+ *		   20 bits (for VAX D format), or the last 21 bits ( for IEEE 
+ *		   double) is 0. This ensures n*ln2hi is exactly representable.
+ *		2. In step 1, f may not be representable. A correction term c
+ *	 	   for f is computed. It follows that the correction term for
+ *		   f - t (the leading term of log(1+f) in step 2) is c-c*x. We
+ *		   add this correction term to n*ln2lo to attenuate the error.
+ *
+ *
+ * Special cases:
+ *	log1p(x) is NaN with signal if x < -1; log1p(NaN) is NaN with no signal;
+ *	log1p(INF) is +INF; log1p(-1) is -INF with signal;
+ *	only log1p(0)=0 is exact for finite argument.
+ *
+ * Accuracy:
+ *	log1p(x) returns the exact log(1+x) nearly rounded. In a test run 
+ *	with 1,536,000 random arguments on a VAX, the maximum observed
+ *	error was .846 ulps (units in the last place).
+ *
+ * Constants:
+ * The hexadecimal values are the intended ones for the following constants.
+ * The decimal values may be used, provided that the compiler will convert
+ * from decimal to binary accurately enough to produce the hexadecimal values
+ * shown.

+/* An improved random number generation package.  In addition to the standard
+   rand()/srand() like interface, this package also has a special state info
+   interface.  The initstate() routine is called with a seed, an array of
+   bytes, and a count of how many bytes are being passed in; this array is
+   then initialized to contain information for random number generation with
+   that much state information.  Good sizes for the amount of state
+   information are 32, 64, 128, and 256 bytes.  The state can be switched by
+   calling the setstate() function with the same array as was initiallized
+   with initstate().  By default, the package runs with 128 bytes of state
+   information and generates far better random numbers than a linear
+   congruential generator.  If the amount of state information is less than
+   32 bytes, a simple linear congruential R.N.G. is used.  Internally, the
+   state information is treated as an array of longs; the zeroeth element of
+   the array is the type of R.N.G. being used (small integer); the remainder
+   of the array is the state information for the R.N.G.  Thus, 32 bytes of
+   state information will give 7 longs worth of state information, which will
+   allow a degree seven polynomial.  (Note: The zeroeth word of state
+   information also has some other information stored in it; see setstate
+   for details).  The random number generation technique is a linear feedback
+   shift register approach, employing trinomials (since there are fewer terms
+   to sum up that way).  In this approach, the least significant bit of all
+   the numbers in the state table will act as a linear feedback shift register,
+   and will have period 2^deg - 1 (where deg is the degree of the polynomial
+   being used, assuming that the polynomial is irreducible and primitive).
+   The higher order bits will have longer periods, since their values are
+   also influenced by pseudo-random carries out of the lower bits.  The
+   total period of the generator is approximately deg*(2**deg - 1); thus
+   doubling the amount of state information has a vast influence on the
+   period of the generator.  Note: The deg*(2**deg - 1) is an approximation
+   only good for large deg, when the period of the shift register is the
+   dominant factor.  With deg equal to seven, the period is actually much
+   longer than the 7*(2**7 - 1) predicted by this formula.  */

+   the one at the front pointer.  Then both pointers are advanced to the next
+   location cyclically in the table.  The value returned is the sum generated,
+   reduced to 31 bits by throwing away the "least random" low bit.
+   Note: The code takes advantage of the fact that both the front and
+   rear pointers can't wrap on the same call by not testing the rear
+   pointer if the front one has wrapped.  Returns a 31-bit random number.  */

+ * Some IEEE standard 754 recommended functions and remainder and sqrt for 
+ * supporting the C elementary functions.
+ ******************************************************************************
+ * WARNING:
+ *      These codes are developed (in double) to support the C elementary
+ * functions temporarily. They are not universal, and some of them are very
+ * slow (in particular, drem and sqrt is extremely inefficient). Each 
+ * computer system should have its implementation of these functions using 
+ * its own assembler.
+ ******************************************************************************
+ *
+ * IEEE 754 required operations:
+ *     drem(x,p) 
+ *              returns  x REM y  =  x - [x/y]*y , where [x/y] is the integer
+ *              nearest x/y; in half way case, choose the even one.
+ *     sqrt(x) 
+ *              returns the square root of x correctly rounded according to 
+ *		the rounding mod.
+ *
+ * IEEE 754 recommended functions:
+ * (a) copysign(x,y) 
+ *              returns x with the sign of y. 
+ * (b) scalb(x,N) 
+ *              returns  x * (2**N), for integer values N.
+ * (c) logb(x) 
+ *              returns the unbiased exponent of x, a signed integer in 
+ *              double precision, except that logb(0) is -INF, logb(INF) 
+ *              is +INF, and logb(NAN) is that NAN.
+ * (d) finite(x) 
+ *              returns the value TRUE if -INF < x < +INF and returns 
+ *              FALSE otherwise.

+Common Public License Version 1.0
+
+   THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS COMMON
+   PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF
+   THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
+   
+   1. DEFINITIONS 
+   
+   "Contribution" means:
+   
+     a) in the case of the initial Contributor, the initial code and
+     documentation distributed under this Agreement, and
+     
+     b) in the case of each subsequent Contributor:
+     
+     i) changes to the Program, and
+     
+     ii) additions to the Program;
+     
+     where such changes and/or additions to the Program originate from
+     and are distributed by that particular Contributor. A Contribution
+     'originates' from a Contributor if it was added to the Program by
+     such Contributor itself or anyone acting on such Contributor's
+     behalf. Contributions do not include additions to the Program
+     which: (i) are separate modules of software distributed in
+     conjunction with the Program under their own license agreement, and
+     (ii) are not derivative works of the Program.
+     
+   "Contributor" means any person or entity that distributes the Program.
+   
+   "Licensed Patents " mean patent claims licensable by a Contributor
+   which are necessarily infringed by the use or sale of its Contribution
+   alone or when combined with the Program.
+   
+   "Program" means the Contributions distributed in accordance with this
+   Agreement.
+   
+   "Recipient" means anyone who receives the Program under this
+   Agreement, including all Contributors.
+   
+   2. GRANT OF RIGHTS
+   
+     a) Subject to the terms of this Agreement, each Contributor hereby
+     grants Recipient a non-exclusive, worldwide, royalty-free copyright
+     license to reproduce, prepare derivative works of, publicly
+     display, publicly perform, distribute and sublicense the
+     Contribution of such Contributor, if any, and such derivative
+     works, in source code and object code form.
+     
+     b) Subject to the terms of this Agreement, each Contributor hereby
+     grants Recipient a non-exclusive, worldwide, royalty-free patent
+     license under Licensed Patents to make, use, sell, offer to sell,
+     import and otherwise transfer the Contribution of such Contributor,
+     if any, in source code and object code form. This patent license
+     shall apply to the combination of the Contribution and the Program
+     if, at the time the Contribution is added by the Contributor, such
+     addition of the Contribution causes such combination to be covered
+     by the Licensed Patents. The patent license shall not apply to any
+     other combinations which include the Contribution. No hardware per
+     se is licensed hereunder.
+     
+     c) Recipient understands that although each Contributor grants the
+     licenses to its Contributions set forth herein, no assurances are
+     provided by any Contributor that the Program does not infringe the
+     patent or other intellectual property rights of any other entity.
+     Each Contributor disclaims any liability to Recipient for claims
+     brought by any other entity based on infringement of intellectual
+     property rights or otherwise. As a condition to exercising the
+     rights and licenses granted hereunder, each Recipient hereby
+     assumes sole responsibility to secure any other intellectual
+     property rights needed, if any. For example, if a third party
+     patent license is required to allow Recipient to distribute the
+     Program, it is Recipient's responsibility to acquire that license
+     before distributing the Program.
+     
+     d) Each Contributor represents that to its knowledge it has
+     sufficient copyright rights in its Contribution, if any, to grant
+     the copyright license set forth in this Agreement.
+     
+   3. REQUIREMENTS
+   
+   A Contributor may choose to distribute the Program in object code form
+   under its own license agreement, provided that:
+   
+     a) it complies with the terms and conditions of this Agreement; and
+     
+     b) its license agreement:
+     
+     i) effectively disclaims on behalf of all Contributors all
+     warranties and conditions, express and implied, including
+     warranties or conditions of title and non-infringement, and implied
+     warranties or conditions of merchantability and fitness for a
+     particular purpose;
+     
+     ii) effectively excludes on behalf of all Contributors all
+     liability for damages, including direct, indirect, special,
+     incidental and consequential damages, such as lost profits;
+     
+     iii) states that any provisions which differ from this Agreement
+     are offered by that Contributor alone and not by any other party;
+     and
+     
+     iv) states that source code for the Program is available from such
+     Contributor, and informs licensees how to obtain it in a reasonable
+     manner on or through a medium customarily used for software
+     exchange.
+     
+   When the Program is made available in source code form:
+   
+     a) it must be made available under this Agreement; and
+     
+     b) a copy of this Agreement must be included with each copy of the
+     Program.
+     
+   Contributors may not remove or alter any copyright notices contained
+   within the Program.
+   
+   Each Contributor must identify itself as the originator of its
+   Contribution, if any, in a manner that reasonably allows subsequent
+   Recipients to identify the originator of the Contribution.
+   
+   4. COMMERCIAL DISTRIBUTION
+   
+   Commercial distributors of software may accept certain
+   responsibilities with respect to end users, business partners and the
+   like. While this license is intended to facilitate the commercial use
+   of the Program, the Contributor who includes the Program in a
+   commercial product offering should do so in a manner which does not
+   create potential liability for other Contributors. Therefore, if a
+   Contributor includes the Program in a commercial product offering,
+   such Contributor ("Commercial Contributor") hereby agrees to defend
+   and indemnify every other Contributor ("Indemnified Contributor")
+   against any losses, damages and costs (collectively "Losses") arising
+   from claims, lawsuits and other legal actions brought by a third party
+   against the Indemnified Contributor to the extent caused by the acts
+   or omissions of such Commercial Contributor in connection with its
+   distribution of the Program in a commercial product offering. The
+   obligations in this section do not apply to any claims or Losses
+   relating to any actual or alleged intellectual property infringement.
+   In order to qualify, an Indemnified Contributor must: a) promptly
+   notify the Commercial Contributor in writing of such claim, and b)
+   allow the Commercial Contributor to control, and cooperate with the
+   Commercial Contributor in, the defense and any related settlement
+   negotiations. The Indemnified Contributor may participate in any such
+   claim at its own expense.
+   
+   For example, a Contributor might include the Program in a commercial
+   product offering, Product X. That Contributor is then a Commercial
+   Contributor. If that Commercial Contributor then makes performance
+   claims, or offers warranties related to Product X, those performance
+   claims and warranties are such Commercial Contributor's responsibility
+   alone. Under this section, the Commercial Contributor would have to
+   defend claims against the other Contributors related to those
+   performance claims and warranties, and if a court requires any other
+   Contributor to pay any damages as a result, the Commercial Contributor
+   must pay those damages.
+   
+   5. NO WARRANTY
+   
+   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
+   PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
+   KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY
+   WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY
+   OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
+   responsible for determining the appropriateness of using and
+   distributing the Program and assumes all risks associated with its
+   exercise of rights under this Agreement, including but not limited to
+   the risks and costs of program errors, compliance with applicable
+   laws, damage to or loss of data, programs or equipment, and
+   unavailability or interruption of operations.
+   
+   6. DISCLAIMER OF LIABILITY 
+   
+   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
+   ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
+   INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
+   WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
+   LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
+   NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
+   DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
+   HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+   
+   7. GENERAL
+   
+   If any provision of this Agreement is invalid or unenforceable under
+   applicable law, it shall not affect the validity or enforceability of
+   the remainder of the terms of this Agreement, and without further
+   action by the parties hereto, such provision shall be reformed to the
+   minimum extent necessary to make such provision valid and enforceable.
+   
+   If Recipient institutes patent litigation against a Contributor with
+   respect to a patent applicable to software (including a cross-claim or
+   counterclaim in a lawsuit), then any patent licenses granted by that
+   Contributor to such Recipient under this Agreement shall terminate as
+   of the date such litigation is filed. In addition, if Recipient
+   institutes patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Program
+   itself (excluding combinations of the Program with other software or
+   hardware) infringes such Recipient's patent(s), then such Recipient's
+   rights granted under Section 2(b) shall terminate as of the date such
+   litigation is filed.
+   
+   All Recipient's rights under this Agreement shall terminate if it
+   fails to comply with any of the material terms or conditions of this
+   Agreement and does not cure such failure in a reasonable period of
+   time after becoming aware of such noncompliance. If all Recipient's
+   rights under this Agreement terminate, Recipient agrees to cease use
+   and distribution of the Program as soon as reasonably practicable.
+   However, Recipient's obligations under this Agreement and any licenses
+   granted by Recipient relating to the Program shall continue and
+   survive.
+   
+   Everyone is permitted to copy and distribute copies of this Agreement,
+   but in order to avoid inconsistency the Agreement is copyrighted and
+   may only be modified in the following manner. The Agreement Steward
+   reserves the right to publish new versions (including revisions) of
+   this Agreement from time to time. No one other than the Agreement
+   Steward has the right to modify this Agreement. IBM is the initial
+   Agreement Steward. IBM may assign the responsibility to serve as the
+   Agreement Steward to a suitable separate entity. Each new version of
+   the Agreement will be given a distinguishing version number. The
+   Program (including Contributions) may always be distributed subject to
+   the version of the Agreement under which it was received. In addition,
+   after a new version of the Agreement is published, Contributor may
+   elect to distribute the Program (including its Contributions) under
+   the new version. Except as expressly stated in Sections 2(a) and 2(b)
+   above, Recipient receives no rights or licenses to the intellectual
+   property of any Contributor under this Agreement, whether expressly,
+   by implication, estoppel or otherwise. All rights in the Program not
+   expressly granted under this Agreement are reserved.
+   
+   This Agreement is governed by the laws of the State of New York and
+   the intellectual property laws of the United States of America. No
+   party to this Agreement will bring a legal action under this Agreement
+   more than one year after the cause of action arose. Each party waives
+   its rights to a jury trial in any resulting litigation.

+USAGE_LICENSE
+"[+NAME?chmod - change the access permissions of files]"
+"[+DESCRIPTION?\bchmod\b changes the permission of each file "
+	"according to mode, which can be either a symbolic representation "
+	"of changes to make, or an octal number representing the bit "
+	"pattern for the new permissions.]"
+"[+?Symbolic mode strings consist of one or more comma separated list "
+	"of operations that can be perfomed on the mode. Each operation is of "
+	"the form \auser\a \aop\a \aperm\a where \auser\a is zero or more of "
+	"the following letters:]{"
+	"[+u?User permission bits.]"
+	"[+g?Group permission bits.]"
+	"[+o?Other permission bits.]"
+	"[+a?All permission bits. This is the default if none are specified.]"
+	"}"
+"[+?The \aperm\a portion consists of zero or more of the following letters:]{"
+	"[+r?Read permission.]"
+	"[+s?Setuid when \bu\b is selected for \awho\a and setgid when \bg\b "
+		"is selected for \awho\a.]"
+	"[+w?Write permission.]"
+	"[+x?Execute permission for files, search permission for directories.]"
+	"[+X?Same as \bx\b except that it is ignored for files that do not "
+		"already have at least one \bx\b bit set.]"
+	"[+l?Exclusive lock bit on systems that support it. Group execute "
+		"must be off.]"
+	"[+t?Sticky bit on systems that support it.]"
+	"}"
+"[+?The \aop\a portion consists of one or more of the following characters:]{"
+	"[++?Cause the permission selected to be added to the existing "
+		"permissions. | is equivalent to +.]"
+	"[+-?Cause the permission selected to be removed to the existing "
+		"permissions.]"
+	"[+=?Cause the permission to be set to the given permissions.]"
+	"[+&?Cause the permission selected to be \aand\aed with the existing "
+		"permissions.]"
+	"[+^?Cause the permission selected to be propagated to more "
+		"restrictive groups.]"
+	"}"
+"[+?Symbolic modes with the \auser\a portion omitted are subject to "
+	"\bumask\b(2) settings unless the \b=\b \aop\a or the "
+	"\b--ignore-umask\b option is specified.]"
+"[+?A numeric mode is from one to four octal digits (0-7), "
+	"derived by adding up the bits with values 4, 2, and 1. "
+	"Any omitted digits are assumed to be leading zeros. The "
+	"first digit selects the set user ID (4) and set group ID "
+	"(2) and save text image (1) attributes. The second digit "
+	"selects permissions for the user who owns the file: read "
+	"(4), write (2), and execute (1); the third selects permissions"
+	"for other users in the file's group, with the same values; "
+	"and the fourth for other users not in the file's group, with "
+	"the same values.]"
+
+"[+?For symbolic links, by default, \bchmod\b changes the mode on the file "
+	"referenced by the symbolic link, not on the symbolic link itself. "
+	"The \b-h\b options can be specified to change the mode of the link. "
+	"When traversing directories with \b-R\b, \bchmod\b either follows "
+	"symbolic links or does not follow symbolic links, based on the "
+	"options \b-H\b, \b-L\b, and \b-P\b. The configuration parameter "
+	"\bPATH_RESOLVE\b determines the default behavior if none of these "
+	"options is specified.]"
+
+"[+?When the \b-c\b or \b-v\b options are specified, change notifications "
+	"are written to standard output using the format, "
+	"\bmode of %s changed to %0.4o (%s)\b, with arguments of the "
+	"pathname, the numeric mode, and the resulting permission bits as "
+	"would be displayed by the \bls\b command.]"
+
+"[+?For backwards compatibility, if an invalid option is given that is a valid "
+	"symbolic mode specification, \bchmod\b treats this as a mode "
+	"specification rather than as an option specification.]"
+
+"[H:metaphysical?Follow symbolic links for command arguments; otherwise don't "
+	"follow symbolic links when traversing directories.]"
+"[L:logical|follow?Follow symbolic links when traversing directories.]"
+"[P:physical|nofollow?Don't follow symbolic links when traversing directories.]"
+"[R:recursive?Change the mode for files in subdirectories recursively.]"
+"[c:changes?Describe only files whose permission actually change.]"
+"[f:quiet|silent?Do not report files whose permissioins fail to change.]"
+"[h:symlink?Change the mode of the symbolic links on systems that "
+	"support this.]"
+"[i:ignore-umask?Ignore the \bumask\b(2) value in symbolic mode "
+	"expressions. This is probably how you expect \bchmod\b to work.]"
+"[F:reference?Omit the \amode\a operand and use the mode of \afile\a "
+	"instead.]:[file]"
+"[v:verbose?Describe changed permissions of all files.]"
+"\n"
+"\nmode file ...\n"

+"[+DESCRIPTION?\bcut\b bytes, characters, or character-delimited fields "
+	"from one or more files, contatenating them on standard output.]"
+"[+?The option argument \alist\a is a comma-separated or blank-separated "
+	"list of positive numbers and ranges.  Ranges can be of three "
+	"forms.  The first is two positive integers separated by a hyphen "
+	"(\alow\a\b-\b\ahigh\a), which represents all fields from \alow\a to "
+	"\ahigh\a.  The second is a positive number preceded by a hyphen "
+	"(\b-\b\ahigh\a), which represents all fields from field \b1\b to "
+	"\ahigh\a.  The last is a positive number followed by a hyphen "
+	"(\alow\a\b-\b), which represents all fields from \alow\a to the "
+	"last field, inclusive.  Elements in the \alist\a can be repeated, "
+	"can overlap, and can appear in any order.  The order of the "
+	"output is that of the input.]"
+"[+?One and only one of \b-b\b, \b-c\b, or \b-f\b must be specified.]"
+"[+?If no \afile\a is given, or if the \afile\a is \b-\b, \bcut\b "

+	"records of length \areclen\a when used with the \b-b\b or \b-c\b "
+	"option.]"
+"[s:suppress|only-delimited?Suppress lines with no delimiter characters, "
+	"when used with the \b-f\b option.  By default, lines with no "

+"[+NAME?expr - evaluate arguments as an expression]"
+"[+DESCRIPTION?\bexpr\b evaluates an expression given as arguments and writes "
+	"the result to standard output.  The character \b0\b will be written "
+	"to indicate a zero value and nothing will be written to indicate an "
+	"empty string.]"
+"[+?Most of the functionality of \bexpr\b is provided in a more natural "
+	"way by the shell, \bsh\b(1), and \bexpr\b is provided primarily "
+	"for backward compatibility.]"
+"[+?Terms of the expression must be separate arguments.  A string argument is "
+	"one that can not be identified as an integer.  Integer-valued "
+	"arguments may be preceded by a unary plus or minus sign.  Because "
+	"many of the operators use characters that have special meaning to "
+	"the shell, they must be quoted when entered from the shell.]"
+
+"[+?Expressions are formed from the operators listed below in order "
+	"of increasing precedence within groups.  All of the operators are "
+	"left associative. The symbols \aexpr1\a and \aexpr2\a represent "
+	"expressions formed from strings and integers and the following "
+	"operators:]{"
+	"[+\aexpr1\a \b|\b \aexpr2\a?Returns the evaluation of \aexpr1\a if "
+	"it is neither null nor 0, otherwise returns the evaluation of expr2.]"
+
+	"[+\aexpr1\a \b&\b \aexpr2\a?Returns the evaluation of \aexpr1\a if "
+	"neither expression evaluates to null or 0, otherwise returns 0.]"
+
+	"[+\aexpr1\a \aop\a \aexpr2\a?Returns the result of a decimal integer "
+	"comparison if both arguments are integers; otherwise, returns the "
+	"result of a string comparison using the locale-specific collation "
+	"sequence. The result of each comparison will be 1 if the specified "
+	"relationship is true, or 0 if the relationship is false.  \aop\a "
+	"can be one of the following:]{"
+		"[+=?Equal.]"
+		"[+==?Equal.]"
+		"[+>?Greater than.]"
+		"[+>=?Greater than or equal to.]"
+		"[+<?Less than.]"
+		"[+<=?Less than or equal to.]"

+	"then the remaining fields from \afile1\a, then the remaining "
+	"fields from \afile2\a, but this can be changed with the \b-o\b "
+	"option.  The \b-a\b option can be used to add unmatched lines "

+   THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS COMMON
+   PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF
+   THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
+   
+   1. DEFINITIONS 
+   
+   "Contribution" means:
+   
+     a) in the case of the initial Contributor, the initial code and
+     documentation distributed under this Agreement, and
+     
+     b) in the case of each subsequent Contributor:
+     
+     i) changes to the Program, and
+     
+     ii) additions to the Program;
+     
+     where such changes and/or additions to the Program originate from
+     and are distributed by that particular Contributor. A Contribution
+     'originates' from a Contributor if it was added to the Program by
+     such Contributor itself or anyone acting on such Contributor's
+     behalf. Contributions do not include additions to the Program
+     which: (i) are separate modules of software distributed in
+     conjunction with the Program under their own license agreement, and
+     (ii) are not derivative works of the Program.
+     
+   "Contributor" means any person or entity that distributes the Program.
+   
+   "Licensed Patents " mean patent claims licensable by a Contributor
+   which are necessarily infringed by the use or sale of its Contribution
+   alone or when combined with the Program.
+   
+   "Program" means the Contributions distributed in accordance with this
+   Agreement.
+   
+   "Recipient" means anyone who receives the Program under this
+   Agreement, including all Contributors.
+   
+   2. GRANT OF RIGHTS
+   
+     a) Subject to the terms of this Agreement, each Contributor hereby
+     grants Recipient a non-exclusive, worldwide, royalty-free copyright
+     license to reproduce, prepare derivative works of, publicly
+     display, publicly perform, distribute and sublicense the
+     Contribution of such Contributor, if any, and such derivative
+     works, in source code and object code form.
+     
+     b) Subject to the terms of this Agreement, each Contributor hereby
+     grants Recipient a non-exclusive, worldwide, royalty-free patent
+     license under Licensed Patents to make, use, sell, offer to sell,
+     import and otherwise transfer the Contribution of such Contributor,
+     if any, in source code and object code form. This patent license
+     shall apply to the combination of the Contribution and the Program
+     if, at the time the Contribution is added by the Contributor, such
+     addition of the Contribution causes such combination to be covered
+     by the Licensed Patents. The patent license shall not apply to any
+     other combinations which include the Contribution. No hardware per
+     se is licensed hereunder.
+     
+     c) Recipient understands that although each Contributor grants the
+     licenses to its Contributions set forth herein, no assurances are
+     provided by any Contributor that the Program does not infringe the
+     patent or other intellectual property rights of any other entity.
+     Each Contributor disclaims any liability to Recipient for claims
+     brought by any other entity based on infringement of intellectual
+     property rights or otherwise. As a condition to exercising the
+     rights and licenses granted hereunder, each Recipient hereby
+     assumes sole responsibility to secure any other intellectual
+     property rights needed, if any. For example, if a third party
+     patent license is required to allow Recipient to distribute the
+     Program, it is Recipient's responsibility to acquire that license
+     before distributing the Program.
+     
+     d) Each Contributor represents that to its knowledge it has
+     sufficient copyright rights in its Contribution, if any, to grant
+     the copyright license set forth in this Agreement.
+     
+   3. REQUIREMENTS
+   
+   A Contributor may choose to distribute the Program in object code form
+   under its own license agreement, provided that:
+   
+     a) it complies with the terms and conditions of this Agreement; and
+     
+     b) its license agreement:
+     
+     i) effectively disclaims on behalf of all Contributors all
+     warranties and conditions, express and implied, including
+     warranties or conditions of title and non-infringement, and implied
+     warranties or conditions of merchantability and fitness for a
+     particular purpose;
+     
+     ii) effectively excludes on behalf of all Contributors all
+     liability for damages, including direct, indirect, special,
+     incidental and consequential damages, such as lost profits;
+     
+     iii) states that any provisions which differ from this Agreement
+     are offered by that Contributor alone and not by any other party;
+     and
+     
+     iv) states that source code for the Program is available from such
+     Contributor, and informs licensees how to obtain it in a reasonable
+     manner on or through a medium customarily used for software
+     exchange.
+     
+   When the Program is made available in source code form:
+   
+     a) it must be made available under this Agreement; and
+     
+     b) a copy of this Agreement must be included with each copy of the
+     Program.
+     
+   Contributors may not remove or alter any copyright notices contained
+   within the Program.
+   
+   Each Contributor must identify itself as the originator of its
+   Contribution, if any, in a manner that reasonably allows subsequent
+   Recipients to identify the originator of the Contribution.
+   
+   4. COMMERCIAL DISTRIBUTION
+   
+   Commercial distributors of software may accept certain
+   responsibilities with respect to end users, business partners and the
+   like. While this license is intended to facilitate the commercial use
+   of the Program, the Contributor who includes the Program in a
+   commercial product offering should do so in a manner which does not
+   create potential liability for other Contributors. Therefore, if a
+   Contributor includes the Program in a commercial product offering,
+   such Contributor ("Commercial Contributor") hereby agrees to defend
+   and indemnify every other Contributor ("Indemnified Contributor")
+   against any losses, damages and costs (collectively "Losses") arising
+   from claims, lawsuits and other legal actions brought by a third party
+   against the Indemnified Contributor to the extent caused by the acts
+   or omissions of such Commercial Contributor in connection with its
+   distribution of the Program in a commercial product offering. The
+   obligations in this section do not apply to any claims or Losses
+   relating to any actual or alleged intellectual property infringement.
+   In order to qualify, an Indemnified Contributor must: a) promptly
+   notify the Commercial Contributor in writing of such claim, and b)
+   allow the Commercial Contributor to control, and cooperate with the
+   Commercial Contributor in, the defense and any related settlement
+   negotiations. The Indemnified Contributor may participate in any such
+   claim at its own expense.
+   
+   For example, a Contributor might include the Program in a commercial
+   product offering, Product X. That Contributor is then a Commercial
+   Contributor. If that Commercial Contributor then makes performance
+   claims, or offers warranties related to Product X, those performance
+   claims and warranties are such Commercial Contributor's responsibility
+   alone. Under this section, the Commercial Contributor would have to
+   defend claims against the other Contributors related to those
+   performance claims and warranties, and if a court requires any other
+   Contributor to pay any damages as a result, the Commercial Contributor
+   must pay those damages.
+   
+   5. NO WARRANTY
+   
+   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
+   PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
+   KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY
+   WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY
+   OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
+   responsible for determining the appropriateness of using and
+   distributing the Program and assumes all risks associated with its
+   exercise of rights under this Agreement, including but not limited to
+   the risks and costs of program errors, compliance with applicable
+   laws, damage to or loss of data, programs or equipment, and
+   unavailability or interruption of operations.
+   
+   6. DISCLAIMER OF LIABILITY 
+   
+   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
+   ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
+   INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
+   WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
+   LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
+   NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
+   DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
+   HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+   
+   7. GENERAL
+   
+   If any provision of this Agreement is invalid or unenforceable under
+   applicable law, it shall not affect the validity or enforceability of
+   the remainder of the terms of this Agreement, and without further
+   action by the parties hereto, such provision shall be reformed to the
+   minimum extent necessary to make such provision valid and enforceable.
+   
+   If Recipient institutes patent litigation against a Contributor with
+   respect to a patent applicable to software (including a cross-claim or
+   counterclaim in a lawsuit), then any patent licenses granted by that
+   Contributor to such Recipient under this Agreement shall terminate as
+   of the date such litigation is filed. In addition, if Recipient
+   institutes patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Program
+   itself (excluding combinations of the Program with other software or
+   hardware) infringes such Recipient's patent(s), then such Recipient's
+   rights granted under Section 2(b) shall terminate as of the date such
+   litigation is filed.
+   
+   All Recipient's rights under this Agreement shall terminate if it
+   fails to comply with any of the material terms or conditions of this
+   Agreement and does not cure such failure in a reasonable period of
+   time after becoming aware of such noncompliance. If all Recipient's
+   rights under this Agreement terminate, Recipient agrees to cease use
+   and distribution of the Program as soon as reasonably practicable.
+   However, Recipient's obligations under this Agreement and any licenses
+   granted by Recipient relating to the Program shall continue and
+   survive.
+   
+   Everyone is permitted to copy and distribute copies of this Agreement,
+   but in order to avoid inconsistency the Agreement is copyrighted and
+   may only be modified in the following manner. The Agreement Steward
+   reserves the right to publish new versions (including revisions) of
+   this Agreement from time to time. No one other than the Agreement
+   Steward has the right to modify this Agreement. IBM is the initial
+   Agreement Steward. IBM may assign the responsibility to serve as the
+   Agreement Steward to a suitable separate entity. Each new version of
+   the Agreement will be given a distinguishing version number. The
+   Program (including Contributions) may always be distributed subject to
+   the version of the Agreement under which it was received. In addition,
+   after a new version of the Agreement is published, Contributor may
+   elect to distribute the Program (including its Contributions) under
+   the new version. Except as expressly stated in Sections 2(a) and 2(b)
+   above, Recipient receives no rights or licenses to the intellectual
+   property of any Contributor under this Agreement, whether expressly,
+   by implication, estoppel or otherwise. All rights in the Program not
+   expressly granted under this Agreement are reserved.
+   
+   This Agreement is governed by the laws of the State of New York and
+   the intellectual property laws of the United States of America. No
+   party to this Agreement will bring a legal action under this Agreement
+   more than one year after the cause of action arose. Each party waives
+   its rights to a jury trial in any resulting litigation.

+
+Common Public License Version 1.0
+
+   THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS COMMON
+   PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF
+   THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
+   
+   1. DEFINITIONS 
+   
+   "Contribution" means:
+   
+     a) in the case of the initial Contributor, the initial code and
+     documentation distributed under this Agreement, and
+     
+     b) in the case of each subsequent Contributor:
+     
+     i) changes to the Program, and
+     
+     ii) additions to the Program;
+     
+     where such changes and/or additions to the Program originate from
+     and are distributed by that particular Contributor. A Contribution
+     'originates' from a Contributor if it was added to the Program by
+     such Contributor itself or anyone acting on such Contributor's
+     behalf. Contributions do not include additions to the Program
+     which: (i) are separate modules of software distributed in
+     conjunction with the Program under their own license agreement, and
+     (ii) are not derivative works of the Program.
+     
+   "Contributor" means any person or entity that distributes the Program.
+   
+   "Licensed Patents " mean patent claims licensable by a Contributor
+   which are necessarily infringed by the use or sale of its Contribution
+   alone or when combined with the Program.
+   
+   "Program" means the Contributions distributed in accordance with this
+   Agreement.
+   
+   "Recipient" means anyone who receives the Program under this
+   Agreement, including all Contributors.
+   
+   2. GRANT OF RIGHTS
+   
+     a) Subject to the terms of this Agreement, each Contributor hereby
+     grants Recipient a non-exclusive, worldwide, royalty-free copyright
+     license to reproduce, prepare derivative works of, publicly
+     display, publicly perform, distribute and sublicense the
+     Contribution of such Contributor, if any, and such derivative
+     works, in source code and object code form.
+     
+     b) Subject to the terms of this Agreement, each Contributor hereby
+     grants Recipient a non-exclusive, worldwide, royalty-free patent
+     license under Licensed Patents to make, use, sell, offer to sell,
+     import and otherwise transfer the Contribution of such Contributor,
+     if any, in source code and object code form. This patent license
+     shall apply to the combination of the Contribution and the Program
+     if, at the time the Contribution is added by the Contributor, such
+     addition of the Contribution causes such combination to be covered
+     by the Licensed Patents. The patent license shall not apply to any
+     other combinations which include the Contribution. No hardware per
+     se is licensed hereunder.
+     
+     c) Recipient understands that although each Contributor grants the
+     licenses to its Contributions set forth herein, no assurances are
+     provided by any Contributor that the Program does not infringe the
+     patent or other intellectual property rights of any other entity.
+     Each Contributor disclaims any liability to Recipient for claims
+     brought by any other entity based on infringement of intellectual
+     property rights or otherwise. As a condition to exercising the
+     rights and licenses granted hereunder, each Recipient hereby
+     assumes sole responsibility to secure any other intellectual
+     property rights needed, if any. For example, if a third party
+     patent license is required to allow Recipient to distribute the
+     Program, it is Recipient's responsibility to acquire that license
+     before distributing the Program.
+     
+     d) Each Contributor represents that to its knowledge it has
+     sufficient copyright rights in its Contribution, if any, to grant
+     the copyright license set forth in this Agreement.
+     
+   3. REQUIREMENTS
+   
+   A Contributor may choose to distribute the Program in object code form
+   under its own license agreement, provided that:
+   
+     a) it complies with the terms and conditions of this Agreement; and
+     
+     b) its license agreement:
+     
+     i) effectively disclaims on behalf of all Contributors all
+     warranties and conditions, express and implied, including
+     warranties or conditions of title and non-infringement, and implied
+     warranties or conditions of merchantability and fitness for a
+     particular purpose;
+     
+     ii) effectively excludes on behalf of all Contributors all
+     liability for damages, including direct, indirect, special,
+     incidental and consequential damages, such as lost profits;
+     
+     iii) states that any provisions which differ from this Agreement
+     are offered by that Contributor alone and not by any other party;
+     and
+     
+     iv) states that source code for the Program is available from such
+     Contributor, and informs licensees how to obtain it in a reasonable
+     manner on or through a medium customarily used for software
+     exchange.
+     
+   When the Program is made available in source code form:
+   
+     a) it must be made available under this Agreement; and
+     
+     b) a copy of this Agreement must be included with each copy of the
+     Program.
+     
+   Contributors may not remove or alter any copyright notices contained
+   within the Program.
+   
+   Each Contributor must identify itself as the originator of its
+   Contribution, if any, in a manner that reasonably allows subsequent
+   Recipients to identify the originator of the Contribution.
+   
+   4. COMMERCIAL DISTRIBUTION
+   
+   Commercial distributors of software may accept certain
+   responsibilities with respect to end users, business partners and the
+   like. While this license is intended to facilitate the commercial use
+   of the Program, the Contributor who includes the Program in a
+   commercial product offering should do so in a manner which does not
+   create potential liability for other Contributors. Therefore, if a
+   Contributor includes the Program in a commercial product offering,
+   such Contributor ("Commercial Contributor") hereby agrees to defend
+   and indemnify every other Contributor ("Indemnified Contributor")
+   against any losses, damages and costs (collectively "Losses") arising
+   from claims, lawsuits and other legal actions brought by a third party
+   against the Indemnified Contributor to the extent caused by the acts
+   or omissions of such Commercial Contributor in connection with its
+   distribution of the Program in a commercial product offering. The
+   obligations in this section do not apply to any claims or Losses
+   relating to any actual or alleged intellectual property infringement.
+   In order to qualify, an Indemnified Contributor must: a) promptly
+   notify the Commercial Contributor in writing of such claim, and b)
+   allow the Commercial Contributor to control, and cooperate with the
+   Commercial Contributor in, the defense and any related settlement
+   negotiations. The Indemnified Contributor may participate in any such
+   claim at its own expense.
+   
+   For example, a Contributor might include the Program in a commercial
+   product offering, Product X. That Contributor is then a Commercial
+   Contributor. If that Commercial Contributor then makes performance
+   claims, or offers warranties related to Product X, those performance
+   claims and warranties are such Commercial Contributor's responsibility
+   alone. Under this section, the Commercial Contributor would have to
+   defend claims against the other Contributors related to those
+   performance claims and warranties, and if a court requires any other
+   Contributor to pay any damages as a result, the Commercial Contributor
+   must pay those damages.
+   
+   5. NO WARRANTY
+   
+   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
+   PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
+   KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY
+   WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY
+   OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
+   responsible for determining the appropriateness of using and
+   distributing the Program and assumes all risks associated with its
+   exercise of rights under this Agreement, including but not limited to
+   the risks and costs of program errors, compliance with applicable
+   laws, damage to or loss of data, programs or equipment, and
+   unavailability or interruption of operations.
+   
+   6. DISCLAIMER OF LIABILITY 
+   
+   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
+   ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
+   INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
+   WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
+   LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
+   NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
+   DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
+   HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+   
+   7. GENERAL
+   
+   If any provision of this Agreement is invalid or unenforceable under
+   applicable law, it shall not affect the validity or enforceability of
+   the remainder of the terms of this Agreement, and without further
+   action by the parties hereto, such provision shall be reformed to the
+   minimum extent necessary to make such provision valid and enforceable.
+   
+   If Recipient institutes patent litigation against a Contributor with
+   respect to a patent applicable to software (including a cross-claim or
+   counterclaim in a lawsuit), then any patent licenses granted by that
+   Contributor to such Recipient under this Agreement shall terminate as
+   of the date such litigation is filed. In addition, if Recipient
+   institutes patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Program
+   itself (excluding combinations of the Program with other software or
+   hardware) infringes such Recipient's patent(s), then such Recipient's
+   rights granted under Section 2(b) shall terminate as of the date such
+   litigation is filed.
+   
+   All Recipient's rights under this Agreement shall terminate if it
+   fails to comply with any of the material terms or conditions of this
+   Agreement and does not cure such failure in a reasonable period of
+   time after becoming aware of such noncompliance. If all Recipient's
+   rights under this Agreement terminate, Recipient agrees to cease use
+   and distribution of the Program as soon as reasonably practicable.
+   However, Recipient's obligations under this Agreement and any licenses
+   granted by Recipient relating to the Program shall continue and
+   survive.
+   
+   Everyone is permitted to copy and distribute copies of this Agreement,
+   but in order to avoid inconsistency the Agreement is copyrighted and
+   may only be modified in the following manner. The Agreement Steward
+   reserves the right to publish new versions (including revisions) of
+   this Agreement from time to time. No one other than the Agreement
+   Steward has the right to modify this Agreement. IBM is the initial
+   Agreement Steward. IBM may assign the responsibility to serve as the
+   Agreement Steward to a suitable separate entity. Each new version of
+   the Agreement will be given a distinguishing version number. The
+   Program (including Contributions) may always be distributed subject to
+   the version of the Agreement under which it was received. In addition,
+   after a new version of the Agreement is published, Contributor may
+   elect to distribute the Program (including its Contributions) under
+   the new version. Except as expressly stated in Sections 2(a) and 2(b)
+   above, Recipient receives no rights or licenses to the intellectual
+   property of any Contributor under this Agreement, whether expressly,
+   by implication, estoppel or otherwise. All rights in the Program not
+   expressly granted under this Agreement are reserved.
+   
+   This Agreement is governed by the laws of the State of New York and
+   the intellectual property laws of the United States of America. No
+   party to this Agreement will bring a legal action under this Agreement
+   more than one year after the cause of action arose. Each party waives
+   its rights to a jury trial in any resulting litigation.

+C preprocessor features:
+
+(1)	The preprocessor is centered around the libpp.a  library.  This
+	library provides a tokenizing implementation of the preprocessing
+	stages of ANSI standard C.  The same library is used to construct
+	a standalone prepreprocessor as well as a C compiler front end
+	that, compiled with the library, eliminates the need for a
+	separate preprocessing pass.  Other C tools requiring C tokenizing
+	can use this library, providing a common interface to C language
+	tokens.
+
+(2)	The #pragma interface is exploited to allow the addition of new
+	directives and #pragma's without changing the preprocessor
+	executable.  Most implementation details can be specified by
+	directives in the file "ppdefault.h" that is automatically included
+	(by the standalone cpp library wrapper) as an initialization step.
+
+(3)	#assert, #unassert and corresponding #if predicate tests have been
+	added to relieve the conflicts introduced by predefined #define
+	macros (e.g., unix, vax, u3b, ...).  This is the same feature
+	present in the extended Reiser cpp that has been included in the
+	nmake distribution. (NOTE: #assert is a failed experiment)
+
+(4)	The implementation is sensitive to the incompatible differences
+	between the Reiser cpp (used by AT&T and BSD compilers) and the new
+	ANSI standard C.  A compatibility dialect implements Reiser
+	features, allowing for a smooth transition to the ANSI standard.
+
+(5)	To aid in the transition to ANSI, the preprocessor can do some
+	operations that would normally be done by the lexical analysis
+	stage of a compiler front end:
+	
+	(a)	convert new-style character constants to a form
+		recognized by all current compilers
+
+	(b)	concatenate adjacent string literals
+
+(6)	The preprocessor can also warn about obsolete constructs used
+	in the compatibility dialect and on non-standard constructs
+	used in the ANSI dialect.  The latter is useful in writing
+	C code that is made to run through other implementations of
+	ANSI standard C.
+
+(7)	The preprocessor allows a C language implementor to take
+	advantage of local extensions without invalidating the
+	conformance of the C language implementation.
+
+C9X additions:
+
+(1)	#pragma STDC ...
+		special forms always accecpted
+
+(2)	_Pragma unary operator for pragmas via macro expansion
+		_Pragma(string-literal)
+			#pragma a b c
+			_Pragma("a b c")
+
+(3)	keywords
+		restrict inline _Bool _Complex _Imaginary

+		__STDC_IEC_559__		1 or undef
+		__STDC_IEC_559_COMPLEX__	1 or udef

+pp \- ANSI C preprocessor library
+.SH SYNOPSIS
+.EX
+:PACKAGE: ast
+#include <pp.h>
+%include "pptokens.yacc
+\-lpp
+.EE
+.SH DESCRIPTION
+The
+.I pp
+library provides a tokenizing implementation of the C language preprocessor
+and supports K&R (Reiser), ANSI and C++ dialects.
+The preprocessor is comprised of 12 public functions,
+a global character class table accessed by macros, and
+a single global struct with 10 public elements.
+.PP
+.I pp
+operates in two modes.
+.I Standalone
+mode is used to implement the traditional standalone C preprocessor.
+.I Tokeinizing
+mode provides a function interface to a stream of preprocessed tokens.
+.I pp
+is by default ANSI; the only default predefined symbols are
+.L __STDC__
+and
+.LR __STDPP__ .
+Dialects (K&R, C++) and local conventions are determined by
+compiler specific
+.IR probe (1)
+information that is included at runtime.
+The
+.I probe
+information can be overridden by providing a file
+.L pp_default.h
+with pragmas and definitions for each compiler implementation.
+This file is usually located in the compiler specific
+default include directory.
+.PP
+Directive, command line argument, option and pragma syntax is described in
+.IR cpp (1).
+.I pp
+specific semantics are described below.
+Most semantic differences with standard or classic implementations are in the
+form of optimizations.
+.PP
+Options and pragmas map to
+.L ppop
+function calls described below.
+For the remaining descriptions,
+``setting \f5ppop(PP_\fP\fIoperation\fP\f5)\fP''
+is a shorthand for calling
+.L ppop
+with the arguments appropriate for
+\f5PP_\fP\fIoperation\fP.
+.PP
+The library interface describes only the public functions and struct elements.
+Static structs and pointers to structs are provided by the library.
+The user should not attempt to allocate structs.
+In particular,
+.L sizeof
+is meaningless for
+.I pp
+supplied structs.
+.PP
+The global struct
+.L pp
+provides readonly information.
+Any changes to
+.L pp
+must be done using the functions described below.
+.L pp
+has the following public elements:
+.TP
+.L "char* version"
+The
+.I pp
+implementaion version string.
+.TP
+.L "char* lineid"
+The current line sync directive name.
+Used for standalone line sync output.
+The default value is the empty string.
+See the
+.L ppline
+function below.
+.TP
+.L "char* outfile"
+The current output file name.
+.TP
+.L "char* pass"
+The pragma pass name for
+.I pp.
+The default value is
+.LR pp .
+.TP
+.L "char* token"
+The string representation for the current input token.
+.TP
+.L "int flags"
+The inclusive or of:
+.RS
+.TP
+.L PP_comment
+Set if 
+.L ppop(PP_COMMENT)
+was set.
+.TP
+.L PP_compatibility
+Set if 
+.L ppop(PP_COMPATIBILITY)
+was set.
+.TP
+.L PP_linefile
+Set if standalone line syncs require a file argument.
+.TP
+.L PP_linetype
+Set if standalone line syncs require a third argument.
+The third argument is
+.L 1
+for include file push,
+.L 2
+for include file pop and null otherwise.
+.TP
+.L PP_strict
+Set if 
+.L ppop(PP_STRICT)
+was set.
+.TP
+.L PP_transition
+Set if 
+.L ppop(PP_TRANSITION)
+was set.
+.RE
+.TP
+.L "struct ppdirs* lcldirs"
+The list of directories to be searched for "..." include files.
+If the first directory name is "" then it is replaced by the
+directory of the including file at include time.
+The public elements of
+.L "struct ppdirs"
+are:
+.RS
+.TP
+.L "char* name"
+The directory pathname.
+.TP
+.L "struct ppdirs* next"
+The next directory,
+.L 0
+if it is the last in the list.
+.RE
+.TP
+.L "struct ppdirs* stddirs"
+.L pp.stddirs\->next
+is the list of directories to be searched for <...> include files.
+This list may be
+.LR 0 .
+.TP
+.L "struct ppsymbol* symbol"
+If
+.L ppop(PP_COMPILE)
+was set then
+.L pp.symbol
+points to the symbol table entry for the current identifier token.
+.L pp.symbol
+is undefined for non-identifier tokens.
+Once defined, an identifier will always have the same
+.L ppsymbol
+pointer.
+If
+.L ppop(PP_NOHASH)
+was also set then
+.L pp.symbol
+is defined for macro and keyword tokens and
+.L 0
+for all other identifiers.

+.L "struct ppsymbol"
+are:
+.RS
+.TP
+.L "char* name"
+The identifier name.

+on are initially unset and may be set by the user.
+.RE
+.PD
+.TP
+.L "struct ppmacro* macro"
+Non-zero if the identifier is a macro.
+.L "int macro\->arity"
+is the number of formal arguments for function-like macros and
+.L "char* macro\->value"

+.RE
+.TP
+.L "Hash_table_t* symtab"
+The macro and identifier
+.L "struct ppsymbol"
+hash table.
+The

+routines may be used to examine the table, with the exception that the
+following macros must be used for individual
+.L pp.symtab
+symbol lookup:
+.RS
+.TP
+.L "struct ppsymbol* ppsymget(Hash_table_t* table, char* name)"
+Return the
+.L ppsymbol
+pointer for

+.L "struct ppsymbol* ppsymset(Hash_table_t* table, char* name)"
+Return the
+.L ppsymbol
+pointer for
+.LR name .
+If
+.L name
+is not defined then allocate and return a new
+.L ppsymbol
+for it.
+.RE
+.RE
+.PP
+Error messages are reported using
+.IR error (3)
+and the following globals relate to
+.IR pp :
+.TP
+.L "int error_info.errors"
+The level 2 error count.
+Error levels above 2 cause immediate exit.
+If
+.L error_info.errors
+is non-zero then the user program exit status should also be non-zero.
+.TP
+.L "char* error_info.file"
+The current input file name.
+.TP
+.L "int error_info.line"
+The current input line number.
+.TP
+.L "int error_info.trace"

+.L 0
+by default.
+Larger negative numbers produce more trace information.
+Enabled when the user program is linked with the
+.B \-g
+.IR cc (1)
+option.
+.TP
+.L "int error_info.warnings"
+The level 1 error count.
+Warnings do not affect the exit status.
+.PP
+The functions are:
+.TP
+.L "extern int ppargs(char** argv, int last);"
+Passed to
+.IR optjoin (3)
+to parse
+.IR cpp (1)
+style options and arguments.
+The user may also supply application specific option parsers.
+Also handles non-standard options like the sun
+.L \-undef
+and GNU
+.LR \-trigraphs .
+Hello in there, ever here of
+.IR getopt (3)?
+.TP
+.L "extern void ppcpp(void);"
+This is the standalone
+.IR cpp (1)
+entry point.
+.L ppcpp
+consumes all of the input and writes the preprocessed text to the output.
+A single call to
+.L ppcpp
+is equivalent to, but more efficient than:
+.EX
+    ppop(PP_SPACEOUT, 1);
+    while (pplex())
+	ppprintf(" %s", pp.token);
+.EE
+.TP
+.L "extern int ppcomment(char* head, char* comment, char* tail, int line);"
+The default comment handler that passes comments to the output.
+May be used as an argument to
+.LR ppop(PP_COMMENT) ,
+or the user may supply an application specific handler.
+.L head
+is the comment head text,
+.L "/*"
+for C and
+.L "//"
+for C++,
+.L comment
+is the comment body,
+.L tail
+is the comment tail text,
+.L "*/"
+for C and
+.B newline
+for C++, and
+.L line
+is the comment starting line number.
+.TP
+.L "extern void pperror(int level, char* format, ...);"
+Equivalent to
+.IR error (3).
+All
+.I pp
+error and warning messages pass through
+.LR pperror .
+The user may link with an application specific
+.L pperror
+to override the library default.
+.TP
+.L "extern int ppincref(char* parent, char* file, int line, int push);"
+The default include reference handler that outputs
+.L file
+to the standard error.
+May be used as an argument to the
+.LR ppop(PP_INCREF) ,
+or the user may supply an application specific handler.
+.L parent
+is the including file name,
+.L file
+is the current include file name,
+.L line
+is the current line number in
+.LR file ,
+and 
+.L push
+is non-zero if
+.L file
+is being pushed or
+.L 0
+if file is being popped.
+.TP
+.L "extern void ppinput(char* buffer, char* file, int line);"
+Pushes the
+.L 0
+terminated
+.L buffer
+on the
+.I pp

+Many C implementations show no restraint in adding new keywords; some
+PC compilers have tripled the number of keywords.
+For the most part these new keywords introduce noise constructs that
+can be ignored for standard
+.RI ( reasonable )
+analysis and compilation.
+The noise keywords fall in four syntactic categories that map into the two
+noise keyword tokens
+.L T_NOISE 
+and 
+.LR T_NOISES .
+For
+.L T_NOISES
+.L pp.token
+points to the entire noise construct, including the offending noise keyword.
+The basic noise keyword categories are:
+.RS
+.TP
+.L T_NOISE
+The simplest noise: a single keyword that is noise in any context and maps to
+.LR T_NOISE .
+.TP
+.L T_X_GROUP
+A noise keyword that precedes an optional grouping construct, either
+.L "(..)"
+or
+.L "{..}"
+and maps to
+.LR T_NOISES .
+.TP
+.L T_X_LINE
+A noise keyword that consumes the remaining tokens in the line
+and maps to
+.LR T_NOISES .
+.TP
+.L T_X_STATEMENT
+A noise keyword that consumes the tokens up to the next
+.L ;
+and maps to
+.LR T_NOISES .
+.RE
+.sp
+If
+.L ppop(PP_NOISE)
+is
+.L "> 0"
+then implementation specific noise constructs are mapped to either
+.L T_NOISE
+or
+.L T_NOISES ,
+otherwise if
+.L ppop(PP_NOISE)
+is
+.L "< 0"
+then noise constructs are completely ignored,
+otherwise the unmapped grouping noise tokens
+.L T_X_.*
+are returned.
+.sp
+Token encodings may be tested by the following macros:
+.RS
+.TP
+.L "int isnumber(int token);"
+Non-zero if
+.L token
+is an integral or floating point numeric constant.
+.TP
+.L "int isinteger(int token);"

+"[+NAME?cpp - C language preprocessor]"
+"[+DESCRIPTION?\bcpp\b is the preprocessor for all C language dialects. It is"
+"	a standalone version of the \blibpp\b(3) preprocessor library. The"
+"	C dialect implemented by \bcpp\b is determined by probing \bcc\b(1)"
+"	using \bprobe\b(1). The path of the emulated compiler can be changed"
+"	by the \b-D-X\b command line option.]"
+"[+?If \aoutput\a is omitted then the standard output is written; if \ainput\a"
+"	is also omitted then the standard input is read. NOTE: this is an"
+"	ancient, non-standard, non-intuitiive file operand syntax that is"
+"	required by \bcc\b(1); use shell file name expansion at your peril.]"
+"[+?\bcpp\b specific options are set by the \b-D-\b and \b-I-\b options.]"
+
+"[C:comments?Pass comments to the output. By default comments are omitted.]"
+"[D:define?Define the macro \aname\a to have \avalue\a; \b1\b is assumed if"

+"	begins with \b%\b then it is interpreted as a \blibpp\b(3) \b#\b"
+"	directive statement; if \aname\a begins with \b-\b or \b+\b then it is"
+"	interpreted as a \blibpp\b(3) option; \b-\b turns the option on,"
+"	\b+\b turns it off. Most options have a \b#pragma\b counterpart that"

+ * lexical FSM encoding
+ * derived from a standalone ansi cpp by Dennis Ritchie
+ * modified for libpp by Glenn Fowler
+ *
+ *   fsm[] is initialized from fsminit[].  The encoding is blown out into
+ *   fsm[] for time efficiency.  When in state state, and one of the
+ *   characters in ch arrives, enter nextstate.  States >= TERMINAL are
+ *   either final, or at least require special action.  In fsminit[] there
+ *   is a line for each <state,charset,nextstate>.  Early entries are
+ *   overwritten by later ones.  C_XXX is the universal set and should
+ *   always be first.  Some of the fsminit[] entries are templates for
+ *   groups of states.  The OP entries trigger the state copies.  States
+ *   above TERMINAL are represented in fsm[] as negative values.  S_TOK and
+ *   S_TOKB encode the resulting token type in the upper bits.  These actions
+ *   differ in that S_TOKB has a lookahead char.
+ *
+ *   fsm[] has three start states:
+ *
+ *	PROTO	proto (ANSI -> K&R,C++,ANSI)
+ *	QUICK	standalone ppcpp()
+ *	TOKEN	tokenizing pplex()
+ *
+ *   If the next state remains the same then the fsm[] transition value is 0.
+ *   MAX+1 is a power of 2 so that fsm[state][EOF==MAX+1] actually accesses
+ *   fsm[state+1][0] which is ~S_EOB for all states.  This preserves the
+ *   power of 2 fsm[] row size for efficient array indexing.  Thanks to
+ *   D. G. Korn for the last two observations.  The pseudo non-terminal state
+ *   fsm[TERMINAL][state+1] is used to differentiate EOB from EOF.
+ *
+ *   The bit layout is:
+ *
+ *	TERM	arg	SPLICE	next
+ *	15	14-8	7	6-0

++------------------------------------------------------------------------------+
+
+Common Public License Version 1.0
+
+   THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS COMMON
+   PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF
+   THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
+   
+   1. DEFINITIONS 
+   
+   "Contribution" means:
+   
+     a) in the case of the initial Contributor, the initial code and
+     documentation distributed under this Agreement, and
+     
+     b) in the case of each subsequent Contributor:
+     
+     i) changes to the Program, and
+     
+     ii) additions to the Program;
+     
+     where such changes and/or additions to the Program originate from
+     and are distributed by that particular Contributor. A Contribution
+     'originates' from a Contributor if it was added to the Program by
+     such Contributor itself or anyone acting on such Contributor's
+     behalf. Contributions do not include additions to the Program
+     which: (i) are separate modules of software distributed in
+     conjunction with the Program under their own license agreement, and
+     (ii) are not derivative works of the Program.
+     
+   "Contributor" means any person or entity that distributes the Program.
+   
+   "Licensed Patents " mean patent claims licensable by a Contributor
+   which are necessarily infringed by the use or sale of its Contribution
+   alone or when combined with the Program.
+   
+   "Program" means the Contributions distributed in accordance with this
+   Agreement.
+   
+   "Recipient" means anyone who receives the Program under this
+   Agreement, including all Contributors.
+   
+   2. GRANT OF RIGHTS
+   
+     a) Subject to the terms of this Agreement, each Contributor hereby
+     grants Recipient a non-exclusive, worldwide, royalty-free copyright
+     license to reproduce, prepare derivative works of, publicly
+     display, publicly perform, distribute and sublicense the
+     Contribution of such Contributor, if any, and such derivative
+     works, in source code and object code form.
+     
+     b) Subject to the terms of this Agreement, each Contributor hereby
+     grants Recipient a non-exclusive, worldwide, royalty-free patent
+     license under Licensed Patents to make, use, sell, offer to sell,
+     import and otherwise transfer the Contribution of such Contributor,
+     if any, in source code and object code form. This patent license
+     shall apply to the combination of the Contribution and the Program
+     if, at the time the Contribution is added by the Contributor, such
+     addition of the Contribution causes such combination to be covered
+     by the Licensed Patents. The patent license shall not apply to any
+     other combinations which include the Contribution. No hardware per
+     se is licensed hereunder.
+     
+     c) Recipient understands that although each Contributor grants the
+     licenses to its Contributions set forth herein, no assurances are
+     provided by any Contributor that the Program does not infringe the
+     patent or other intellectual property rights of any other entity.
+     Each Contributor disclaims any liability to Recipient for claims
+     brought by any other entity based on infringement of intellectual
+     property rights or otherwise. As a condition to exercising the
+     rights and licenses granted hereunder, each Recipient hereby
+     assumes sole responsibility to secure any other intellectual
+     property rights needed, if any. For example, if a third party
+     patent license is required to allow Recipient to distribute the
+     Program, it is Recipient's responsibility to acquire that license
+     before distributing the Program.
+     
+     d) Each Contributor represents that to its knowledge it has
+     sufficient copyright rights in its Contribution, if any, to grant
+     the copyright license set forth in this Agreement.
+     
+   3. REQUIREMENTS
+   
+   A Contributor may choose to distribute the Program in object code form
+   under its own license agreement, provided that:
+   
+     a) it complies with the terms and conditions of this Agreement; and
+     
+     b) its license agreement:
+     
+     i) effectively disclaims on behalf of all Contributors all
+     warranties and conditions, express and implied, including
+     warranties or conditions of title and non-infringement, and implied
+     warranties or conditions of merchantability and fitness for a
+     particular purpose;
+     
+     ii) effectively excludes on behalf of all Contributors all
+     liability for damages, including direct, indirect, special,
+     incidental and consequential damages, such as lost profits;
+     
+     iii) states that any provisions which differ from this Agreement
+     are offered by that Contributor alone and not by any other party;
+     and
+     
+     iv) states that source code for the Program is available from such
+     Contributor, and informs licensees how to obtain it in a reasonable
+     manner on or through a medium customarily used for software
+     exchange.
+     
+   When the Program is made available in source code form:
+   
+     a) it must be made available under this Agreement; and
+     
+     b) a copy of this Agreement must be included with each copy of the
+     Program.
+     
+   Contributors may not remove or alter any copyright notices contained
+   within the Program.
+   
+   Each Contributor must identify itself as the originator of its
+   Contribution, if any, in a manner that reasonably allows subsequent
+   Recipients to identify the originator of the Contribution.
+   
+   4. COMMERCIAL DISTRIBUTION
+   
+   Commercial distributors of software may accept certain
+   responsibilities with respect to end users, business partners and the
+   like. While this license is intended to facilitate the commercial use
+   of the Program, the Contributor who includes the Program in a
+   commercial product offering should do so in a manner which does not
+   create potential liability for other Contributors. Therefore, if a
+   Contributor includes the Program in a commercial product offering,
+   such Contributor ("Commercial Contributor") hereby agrees to defend
+   and indemnify every other Contributor ("Indemnified Contributor")
+   against any losses, damages and costs (collectively "Losses") arising
+   from claims, lawsuits and other legal actions brought by a third party
+   against the Indemnified Contributor to the extent caused by the acts
+   or omissions of such Commercial Contributor in connection with its
+   distribution of the Program in a commercial product offering. The
+   obligations in this section do not apply to any claims or Losses
+   relating to any actual or alleged intellectual property infringement.
+   In order to qualify, an Indemnified Contributor must: a) promptly
+   notify the Commercial Contributor in writing of such claim, and b)
+   allow the Commercial Contributor to control, and cooperate with the
+   Commercial Contributor in, the defense and any related settlement
+   negotiations. The Indemnified Contributor may participate in any such
+   claim at its own expense.
+   
+   For example, a Contributor might include the Program in a commercial
+   product offering, Product X. That Contributor is then a Commercial
+   Contributor. If that Commercial Contributor then makes performance
+   claims, or offers warranties related to Product X, those performance
+   claims and warranties are such Commercial Contributor's responsibility
+   alone. Under this section, the Commercial Contributor would have to
+   defend claims against the other Contributors related to those
+   performance claims and warranties, and if a court requires any other
+   Contributor to pay any damages as a result, the Commercial Contributor
+   must pay those damages.
+   
+   5. NO WARRANTY
+   
+   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
+   PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
+   KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY
+   WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY
+   OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
+   responsible for determining the appropriateness of using and
+   distributing the Program and assumes all risks associated with its
+   exercise of rights under this Agreement, including but not limited to
+   the risks and costs of program errors, compliance with applicable
+   laws, damage to or loss of data, programs or equipment, and
+   unavailability or interruption of operations.
+   
+   6. DISCLAIMER OF LIABILITY 
+   
+   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
+   ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
+   INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
+   WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
+   LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
+   NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
+   DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
+   HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+   
+   7. GENERAL
+   
+   If any provision of this Agreement is invalid or unenforceable under
+   applicable law, it shall not affect the validity or enforceability of
+   the remainder of the terms of this Agreement, and without further
+   action by the parties hereto, such provision shall be reformed to the
+   minimum extent necessary to make such provision valid and enforceable.
+   
+   If Recipient institutes patent litigation against a Contributor with
+   respect to a patent applicable to software (including a cross-claim or
+   counterclaim in a lawsuit), then any patent licenses granted by that
+   Contributor to such Recipient under this Agreement shall terminate as
+   of the date such litigation is filed. In addition, if Recipient
+   institutes patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Program
+   itself (excluding combinations of the Program with other software or
+   hardware) infringes such Recipient's patent(s), then such Recipient's
+   rights granted under Section 2(b) shall terminate as of the date such
+   litigation is filed.
+   
+   All Recipient's rights under this Agreement shall terminate if it
+   fails to comply with any of the material terms or conditions of this
+   Agreement and does not cure such failure in a reasonable period of
+   time after becoming aware of such noncompliance. If all Recipient's
+   rights under this Agreement terminate, Recipient agrees to cease use
+   and distribution of the Program as soon as reasonably practicable.
+   However, Recipient's obligations under this Agreement and any licenses
+   granted by Recipient relating to the Program shall continue and
+   survive.
+   
+   Everyone is permitted to copy and distribute copies of this Agreement,
+   but in order to avoid inconsistency the Agreement is copyrighted and
+   may only be modified in the following manner. The Agreement Steward
+   reserves the right to publish new versions (including revisions) of
+   this Agreement from time to time. No one other than the Agreement
+   Steward has the right to modify this Agreement. IBM is the initial
+   Agreement Steward. IBM may assign the responsibility to serve as the
+   Agreement Steward to a suitable separate entity. Each new version of
+   the Agreement will be given a distinguishing version number. The
+   Program (including Contributions) may always be distributed subject to
+   the version of the Agreement under which it was received. In addition,
+   after a new version of the Agreement is published, Contributor may
+   elect to distribute the Program (including its Contributions) under
+   the new version. Except as expressly stated in Sections 2(a) and 2(b)
+   above, Recipient receives no rights or licenses to the intellectual
+   property of any Contributor under this Agreement, whether expressly,
+   by implication, estoppel or otherwise. All rights in the Program not
+   expressly granted under this Agreement are reserved.
+   
+   This Agreement is governed by the laws of the State of New York and
+   the intellectual property laws of the United States of America. No
+   party to this Agreement will bring a legal action under this Agreement
+   more than one year after the cause of action arose. Each party waives
+   its rights to a jury trial in any resulting litigation.

+
+			KSH-93 VS. KSH-88
+
+
+The following is a list of known incompatibilities between ksh-93 and ksh-88.
+I have not include cases that are clearly bugs in ksh-88.  I also have
+omitted features that are completely upward compatible.
+
+1.	Functions, defined with name() with ksh-93 are compatible with
+	the POSIX standard, not with ksh-88.  No local variables are
+	permitted, and there is no separate scope.  Functions defined
+	with the function name syntax, maintain compatibility.
+	This also affects function traces.
+
+2.	! is now a reserved word.  As a result, any command by that
+	name will no longer work with ksh-93.
+
+3.	The -x attribute of alias and typeset -f is no longer
+	effective and the ENV file is only read for interactive
+	shells.  You need to use FPATH to make function definitions
+	visible to scripts.
+
+4.	A built-in command named command has been added which is
+	always found before the PATH search.  Any script which uses
+	this name as the name of a command (or function) will not
+	be compatible.
+
+5.	The output format for some built-ins has changed.  In particular
+	the output format for set, typeset and alias now have single
+	quotes around values that have special characters.  The output
+	for trap without arguments has a format that can be used as input.
+
+6.	With ksh-88, a dollar sign ($') followed by a single quote was
+	interpreted literally.  Now it is an ANSI-C string.  You
+	must quote the dollar sign to get the previous behavior.
+	Also, a $ in front of a " indicates that the string needs
+	to be translated for locales other than C or POSIX.  The $ 
+	is ignored in the C and POSIX locale.
+
+7.	With ksh-88, tilde expansion did not take place inside ${...}.
+	with ksh-93, ${foo-~} will cause tilde expansion if foo is
+	not set.  You need to escape the ~ for the previous behavior.
+
+8.      Some changes in the tokenizing rules where made that might
+	cause some scripts with previously ambiguous use of quoting
+	to produce syntax errors.
+
+9.	Programs that rely on specific exit values for the shell,
+	(rather than 0 or non-zero) may not be compatible.  The
+	exit status for many shell failures has been changed.
+
+10.	Built-ins in ksh-88 were always executed before looking for
+	the command in the PATH variable.  This is no longer true.
+	Thus, with ksh-93, if you have the current directory first
+	in your PATH, and you have a program named test in your
+	directory, it will be executed when you type test; the
+	built-in version will be run at the point /bin is found
+	in your PATH. 
+
+11.	Some undocumented combinations of argument passing to ksh
+	builtins no longer works since ksh-93 is getopts conforming
+	with respect to its built-ins.  For example, typeset -8i
+	previously would work as a synonym for typeset -i8.
+
+12.	Command substitution and arithmetic expansion are now performed
+	on PS1, PS3, and ENV when they are expanded.  Thus,  ` and $(
+	as part of the value of these variables must be preceded by a \
+	to preserve their previous behavior.
+
+13.	The ERRNO variable has been dropped.
+
+14.	If the file name following a redirection symbol contain pattern
+	characters they will only be expanded for interactive shells.
+
+15.	The arguments to a dot script will be restored when it completes. 
+
+16.	The list of tracked aliases is not displayed with alias unless
+	the -t option is specified.
+
+17.	The POSIX standard requires that test "$arg" have exit status
+	of 0, if and only if $arg is null.  However, since this breaks
+	programs that use test -t, ksh93 treats an explicit test -t
+	as if the user had entered test -t 1.
+
+18.	The ^T directive of emacs mode has been changed to work the
+	way it does in gnu-emacs.
+
+19.	ksh-88 allowed unbalanced parenthes within ${name op val} whereas
+	ksh-93 does not.  Thus, ${foo-(} needs to be written as ${foo-\(}
+	which works with both versions.
+
+20.     kill -l in ksh-93 lists only the signal names, not their numerical
+	values.
+
+21.	Local variables defined by typeset are statically scoped in
+	ksh93.  In ksh88 they were dynamically scoped although this
+	behavior was never documented.
+
+22.	The value of the variable given to getopts is set to ? when
+	the end-of-options is reached to conform to the POSIX standard.
+
+23.	Since the POSIX standard requires that octal constants be
+	recongnized, doing arithmetic on typeset -Z variables can
+	yield different results that with ksh88.  Most of these
+	differences were eliminated in ksh93o.
+
+24.	Starting after ksh93l, If you run ksh name, where name does
+	not contain a /, the current directory will be searched
+	before doing a path search on name as required by the POSIX
+	shell standard.  
+
+25.	In ksh93, cd - will output the directory that it changes
+	to on standard output as required by X/Open.  With ksh88,
+	this only happened for interactive shells.
+
+26.	As an undocumented feature of ksh-88, a leading 0 to an
+	assignment of an integer variable caused that variable
+	to be treated as unsigned.  This behavior was removed
+	starting in ksh93p.
+
+27.	The getopts builtin in ksh93 requires that optstring contain
+	a leading + to allow options to begin with a +.
+
+28.	In emacs/gmacs mode, control-v will not display the version when
+	the stty lnext character is set to control-v or is unset.
+	The sequence escape control-v will display the shell version.
+
+I am interested in expanding this list so please let me know if you
+uncover any others.

+Here is an overview of the source code organization for ksh93.
+
+Directory layout:
+
+	The directory include contains header files for ksh93.
+	The files nval.h and shell.h are intended to be public
+	headers and can be used to add runtime builtin command.
+	The remainder are private.
+
+	The directory data contains readonly data files for ksh93.
+
+	The directory edit contains the code for command line
+	editing and history.
+
+	The fun directory contains some shell function such as
+	pushd, popd, and dirs.
+
+	The directory features contains files that are used to generate
+	header files in the FEATURE directory.  Most of these files
+	are in a format that is processed by iffe.
+
+	The directory bltins contains code for most of the built-in
+	commands.  Additional built-in commands are part of libcmd.
+
+	The directory sh contains most of the code for ksh93.
+
+	The directory tests contains a number of regression tests.
+	In most cases, when a bug gets fixed, a test is added to
+	one of these files.  The regression tests can be run by
+	going to this directory and running
+		SHELL=shell_path shell_path shtests
+	where shell_path is an absolute pathname for the shell to
+	be tested.
+
+	The top level directory contains the nmake Makefile, a README,
+	and several documentation files.  The RELEASE file contains
+	the list of bug fixes and new features since the original
+	ksh93 release.  The file COMPATIBILITY is a list of all
+	known incompatibilities with ksh88.
+
+	The  bash_pre_rc.sh is a startup script used when emulating
+	bash if the shell is compiled with SHOPT_BASH and the shell
+	is invoked as bash.  The bash emulation is not complete.
+

+		don't fit elsewhere and it includes several other
+		headers.  It defines a strucuture that contains ksh
+		global data, sh, and a structure that contains per

+	4.	edit.h contains definitions that are common to both
+		vi and emacs edit modes.
+	5.	env.h contains interfaces for creating and modifying
+		environment variables.

+	10.	lexstates.h contains the states associated with
+		lexical processing.
+	11.	name.h contains the internal definitions related
+		to name-value pair processing.
+	12.	national.h contains a few I18N definitions, mostly
+		obsolete.
+	13.	nval.h is the public interface to the name-value
+		pair library that is documented with nval.3.
+	14.	path.h contains the interface for pathname processing
+		and pathname searching.
+	15.	shell.h is the public interface for shell functions
+		that are documented int shell.3.
+	16.	shlex.h contains the lexical token definitions and
+		interfaces for lexical analysis.

+.H 1 ksh93
+KSH-93 is the most recent version of the KornShell Language
+described in
+"The KornShell Command and Programming Language,"
+by Morris Bolsky and David Korn of AT&T Bell Laboratories, ISBN 0-13-182700-6.
+The KornShell is a shell programming language,
+which is upward compatible with "sh" (the Bourne Shell),
+and is intended to conform to the IEEE P1003.2/ISO 9945.2 Shell and
+Utilities standard.
+KSH-93 provides an enhanced programming environment in
+addition to the major command-entry features of the BSD
+shell "csh".  With KSH-93, medium-sized programming tasks can be
+performed at shell-level without a significant loss in performance.
+In addition, "sh" scripts can be run on KSH-93 without modification.
+.P
+The code should conform to the IEEE POSIX 1003.1 standard and to the
+proposed ANSI-C standard so that it should be portable to all
+such systems.  Like the previous version, KSH-88,
+it is designed to accept eight bit character sets
+transparently, thereby making it internationally compatible.
+It can support multi-byte characters sets with some characteristics
+of the character set given at run time.
+.P
+KSH-93 provides the following features, many of which were also inherent
+in KSH-88:
+.BL
+.LI
+Enhanced Command Re-entry Capability:  The KSH-93 history
+function records commands entered at any shell level and stores
+them, up to a user-specified limit, even after you log off.
+This allows you to re-enter long commands with a few keystrokes
+- even those commands you entered yesterday.
+The history file allows for eight bit characters in
+commands and supports essentially unlimited size histories.
+.LI
+In-line Editing: In "sh", the only way to fix mistyped
+commands is to backspace or retype the line. KSH-93 allows you
+to edit a command line using a choice of EMACS-TC or "vi"
+functions.
+You can use the in-line editors to complete filenames as
+you type them.
+You may also use this editing feature when entering
+command lines from your history file.
+A user can capture keystrokes and rebind keys to customize the
+editing interface.
+.LI
+Extended I/O Capabilities:  KSH-93 provides several I/O
+capabilities not available in "sh", including the ability to:
+.BL
+.LI
+specify a file descriptor for input and output
+.LI
+start up and run co-processes
+.LI
+produce a prompt at the terminal before a read
+.LI
+easily format and interpret responses to a menu
+.LI
+echo lines exactly as output without escape processing
+.LI
+format output using printf formats.
+.LI
+read and echo lines ending in "\e".
+.LE
+.LI
+Improved performance: KSH-93 executes many scripts faster
+than the System V Bourne shell. A major reason for this is
+that many of the standard utilities are built-in.
+To reduce the time to initiate a command, KSH-93 allows
+commands to be added as built-ins at run time
+on systems that support dynamic loading such as System V Release 4.
+.LI
+Arithmetic: KSH-93 allows you to do integer arithmetic in any
+base from two to sixty-four.  You can also do double
+precision floating point arithmetic.
+Almost the complete set of C language operators are available
+with the same syntax and precedence.
+Arithmetic expressions can be used to as an argument expansion 
+or as a separate command.
+In addition there is an arithmetic for command that works
+like the for statement in C.
+.LI
+Arrays: KSH-93 supports both indexed and associative arrays.
+The subscript for an indexed array is an arithmetic expression,
+whereas, the subscript for an associative array is a string.
+.LI
+Shell Functions and Aliases: Two mechanisms - functions and
+aliases - can be used to assign a user-selected identifier to
+an existing command or shell script.
+Functions allow local variables and provide scoping
+for exception handling.
+Functions can be searched for and loaded on first reference the
+way scripts are.
+.LI
+Substring Capabilities:  KSH-93 allows you to create a
+substring of any given string either by specifying the starting
+offset and length, or by stripping off leading
+or trailing substrings during parameter substitution.
+You can also specify attributes, such as upper and lower case,
+field width, and justification to shell variables.
+.LI
+More pattern matching capabilities:  KSH-93 allows you to specify
+extended regular expressions for file and string matches.
+.LI
+KSH-93 uses a hierarchal name space for variables.
+Compound variables can be defined and variables can
+be passed by reference.  In addition, each variable
+can have one or more disciplines associated with
+it to intercept assignments and references.
+.LI
+Improved debugging:  KSH-93 can generate line numbers on execution
+traces.  Also, I/O redirections are now traced.
+There is a DEBUG trap that gets evaluated after each command
+so that errors can be localized.
+.LI
+Job Control: On systems that support job control, including
+System V Release 4, KSH-93
+provides a job-control mechanism almost identical to that of
+the BSD "csh", version 4.1.
+This feature allows you
+to stop and restart programs, and to move programs between the
+foreground and the background.
+.LI
+Added security:
+KSH-93 can execute scripts which do not have read permission
+and scripts which have the setuid and/or setgid set when
+invoked by name, rather than as an argument to the shell.
+It is possible to log or control the execution of setuid and/or
+setgid scripts.
+The noclobber option prevents you from accidentally erasing
+a file by redirecting to an existing file.
+.LI
+KSH-93 can be extended by adding built-in commands at run time.
+In addition, KSH-93 can be used as a library that can
+be embedded into an application to allow scripting.
+.LE
+Documentation for KSH-93 consists of an "Introduction to KSH-93",
+"Compatibility with the Bourne Shell" and a manual page and a
+README file.  In addition, the "New KornShell Command and Programming
+Language," book is available from Prentice Hall.

+This directory, and its subdirectories contain the source code
+for ksh-93; the language described in the second addition of
+the book, "The KornShell Command and Programming Language," by
+Morris Bolsky and David Korn which is published by Prentice Hall.
+ksh-93 has been compiled and run on several machines with several
+operating systems.  The end of this file contains a partial list of
+operating systems and machines that ksh-93 has been known to run on.
+
+The layout of files for ksh-93 has changed somewhat since ksh-88,
+the last major release.  Most of the source code for ksh remains in
+the sh directory.  However, the shell editing and history routines
+are in the edit sub-directory.  The code for shell built-ins is
+in the bltins directory.  The data directory contains read-only
+data tables and messages that are used by the shell.  The include
+files remain in the include directory and the shlib directory
+is gone.  The features directory replaces the older install
+directory. The method for generating systems specific feature
+information has changed substantially.
+
+The Makefile file contains several compilation options that can be set
+before compiling ksh.  Options are of the form SHOPT_option and become
+#define inside the code.  These options are set to their recommended
+value and some of these may disappear as options in future releases.
+A value of 0, or no value  represents off, 1 represents on.
+Note that == is needed, not =, because these are nmake state variables
+and changing their value will cause all modules that could be affected
+by this change to be recompiled.
+The options have the following defaults and meanings:
+    ACCT         off Shell accounting.
+    ACCTFILE     off Enable per user accounting info
+    APPEND       on  Allows var+=val string and array append.
+    BASH         off Bash compatibility mode.  It is not fully implemented
+                     and is experimental.
+    BRACEPAT     on  C-shell type abc{d,e}f style file generation
+    CMDLIB_BLTIN off Makes all commands in libcmd.a builtins.  The
+                     SH_CMDLIB_DIR nmake state variable can be used to
+		     specify a directory. 
+    CMDLIB_DIR   off Sets CMDLIB_BLTIN=1 and provides a default value
+                     of "/opt/ast/bin" for SH_CMDLIB_DIR.
+    COMPOUND_ARRAY
+                 on  Allows all components of compound variables except the
+                     first to be any string by enclosing in [...].  It also
+                     allows components other than the last to be arrays.
+                     This is experimental and only partially complete.
+    CRNL         off <cr><nl> treated as <nl> in shell grammar.
+    DYNAMIC      on  Dynamic loading of builtins. (Requires dlopen() interface.)
+    ECHOPRINT    off Make echo equivalent to print.
+    ESH          on  Compile with emacs command line editing.  The original
+                     emacs line editor code was provided by Mike Veach at IH.
+    FILESCAN     on  Experimental option that allows fast reading of files
+                     using while < file;do ...; done and allowing fields in
+                     each line to be accessed as positional parameters.
+    FS_3D        off For use with 3-D file system.  Enabled automatically for
+                     sytems with dynamic linking.
+    KIA          off Allow generation of shell cross reference database with -I.
+    MULTIBYTE    on  Multibyte character handling.  Requires mblen() and
+                     mbctowc().
+    NAMESPACE    on  Allows namespaces.  This is experimental, incomplete
+                     and undocumented.
+    OLDTERMIO    off Use either termios or termio at runtime.
+    OO           on  Experimental object oriented extension.  This option
+                     should disappear soon.
+    OPTIMIZE     on  Optimize loop invariants for with for and while loops.
+    P_SUID       off If set, all real uids, greater than or equal to this
+                     value will require the -p flag to run suid/sgid scripts.
+    PFSH         off Compile with support for profile shell.
+    RAWONLY      off Turn on if the vi line mode doesn't work right unless
+                     you do a set -o viraw.
+    SEVENBIT     off Strip the eigth bit from characters.
+    SPAWN        off Use spawn as combined fork/exec.  May improve speed on
+                     some systems.
+    SUID_EXEC    on  Execute /etc/suid_exec for setuid, setgid script.
+    TIMEOUT      off Set this to the number of seconds for timing out and
+                     exiting the shell when you don't enter a command.  If
+                     non-zero, TMOUT can not be set larger than this value.
+    VSH          on  Compile with vi command line editing.  The original vi
+                     line editor code was provided by Pat Sullivan at CB.
+
+The following compile options are set automatically by the feature testing:
+    DEVFD   Set when /dev/fd is a directory that names open files.
+    SHELLMAGIC
+            Set on systems that recognize script beginning with #! specially.
+    VPIX    Set on systems the have /usr/bin/vpix program for running MS-DOS.
+
+
+In most instances, you will generate ksh from a higher level directory
+which also generates libcmd and libast libraries on which ksh depends.
+However, it is possible to generate ksh, with by running make -f ksh.mk
+in this directory.  The ksh.mk file was generated from the nmake Makefile.
+If you do not have make or nmake, but do have a Version 7 UNIX compatible
+shell, then you can run the script mamexec < Mamfile to build ksh.
+If you have nmake, version 2.3 or later, you can use it without the -f ksh.mk.
+In either case, ksh relies on libraries libast and libcmd which must be
+built first.  The binary for ksh becomes the file named ./ksh which can
+be copied to where ever you install it.
+
+If you use old make or the Mamfile, and you system has dynamic shared
+libraries, then you should define the variables mam_cc_static and
+mam_cc_dynanamic as the compiler options that request static linking
+and dynamic linking respectively.  This will decrease the number of
+shared libraries that ksh need and cut startup time substantially.
+
+The makefile should also generate shcomp, a program that will precompile
+a script.  ksh93 is able to recognize files in this format and process
+them as scripts.  You can use shcomp to send out scripts when you
+don't want to give away the original script source.
+
+It is advisable that you put the line PWD=$HOME;export PWD into the
+/etc/profile file to reduce initialization time for ksh.
+
+To be able to run setuid/setgid shell scripts, or scripts without read
+permission, the SUID_EXEC compile option must be on, and ksh must be installed
+in the /bin directory, the /usr/bin directory, the /usr/lbin directory,
+or the /usr/local/bin directory and the name must end in sh. The program
+suid_exec must be installed in the /etc directory, must be owned by root,
+and must be a suid program.  If you must install ksh in some other directory
+and want to be able to run setuid/setgid and execute only scripts, then
+you will have to change the source code file sh/suid_exec.c explicitly.
+If you do not have ksh in one of these secure locations, /bin/sh will
+be invoked with the -p options and will fail when you execute a setuid/setgid
+and/or execute only script.  Note, that ksh does not read the .profile
+or $ENV file when it the real and effective user/group id's are not
+equal.
+
+The tests sub-directory contains a number of regression tests for ksh.
+To run all these tests with the shell you just built, go to the tests
+directory and run the command
+        SHELL=../ksh shtests
+
+The file PROMO.mm is an advertisement that extolls the virtues of ksh.
+The file sh.1 contains the troff (man) description of this Shell.
+The file nval.3 contains the troff (man) description of the name-value

+RELEASE contains bug fixes made in this release since ksh-88.  The file
+COMPATIBILITY contains a list of incompatibilities with ksh-88.  The
+file bltins.mm is a draft troff (mm) memo describing how to write
+built-in commands that can be loaded at run time.
+
+Most of the work for internationalization has been done with ksh93.
+The file ksh.msg is a generated file that contains error messages
+that need to be translated.  In addition, the function translate()
+in sh/init.c has to be completed to interface with the dictionary
+lookup.  The translate function takes two argument, the string
+that is to be translated and a type which is
+    0 when a library string needs translation.
+    1 when one of the error messages in ksh.msg needs translation.
+    2 when a string in a script needs translation.  You use a $ in front
+      of a double quoted string in a script to indicate that it
+      needs translation.  The -D option for ksh builds the dictionary.
+The translate routine needs to return the translated message.
+For dictionaries that need to use a numeric key, it should be
+possible to use the strhash() function to generate numbers to
+go along with each of the messages and to use this number both
+when generating the dictionary and when converting strings.
+If you encounter error messages of type 1 that are not be translated via
+this translate() function send mail to the address below.

+07-04-18  --- Release ksh93s+  ---
+07-04-18  A small memory leak with each redirection of a non-builtin has
+	  been fixed.
+07-03-08  A bug in which set +o output command line options has been fixed.
+07-03-08  A bug in which an error in read (for example, an invalid variable
+	  name), could leave the terminal in raw mode has been fixed.
+07-03-06  A bug in which read could core dump when specified with an array
+	  variable with a subscript that is an arithmetic expression has
+	  been fixed.
+07-03-06  Several serious bugs with the restricted shell were reported and
+	  fixed.
+07-03-02  If a job is stopped, and subsequently restarted with a CONT
+	  signal and exits normally, ksh93 was incorrectly exiting with
+	  the exit status of the stop signal number.
+07-02-26  M-^L added to emacs mode to clear the screen.
+07-02-26  A bug in which setting a variable readonly in a subshell would
+	  cause an unset error when the subshell completed has been fixed. 
+07-02-19  The format with printf uses the new = flag to center the output.
+07-02-19  A bug in which ksh93 did not allow multibyte characters in
+	  identifier names has been fixed.
+07-02-19  A bug introduced in ksh93 that causes global compound variable
+	  definitions inside functions to exit with "no parent" has been fixed.
+07-02-19  A bug in which using compound commands in process redirection
+	  arguments would give syntax errors <(...) and >(...) has been fixed.
+07-01-29  A bug which caused the shell to core dump which can occur when a
+	  built-in exits without closing files that it opens has been fixed.
+07-01-26  A bug in which ~(E) in patterns containing \ that are not inside ()
+	  has been fixed.
+
+06-12-29  --- Release ksh93s  ---
+06-12-29  A bug in which the value of IFS could be changed after a command
+	  substitution has been fixed. 
+06-12-22  /dev/(tcp|udp|sctp)/HOST/SEVRICE now handles IPv6 addresses on
+	  systems that provide getaddrinfo(3).
+06-12-19  A -v option was added to read.  With this option the value of
+	  the first variable name argument will become the default value
+	  when read from a terminal device. 
+06-11-20  A bug in which "${foo[@]:1}}" expands a null argument (instead of
+	  no argument), when foo[0] is not empty has been fixed. 
+06-11-16  The discipline functions have been modified to allow each subscript
+	  to act independently.  Currently the discipline function will not
+	  be called when called from a discipline function of the same variable.
+06-11-14  A bug which could cause a core dump if a file descriptor for
+	  an internal file was closed from with a subshell has been fixed.
+06-10-30  The redirections <# pattern, and <## pattern have been added.
+	  Both seek forward to the beginning of the next line that contains
+	  the pattern.  The <## form copies the skipped portion to standard
+	  output.
+06-10-26  On systems that support stream control transport, the virtual file
+	  name /dev/sctp/host/port can now be used to establish connections.
+06-10-26  The printf modifier # when used with d produces units in thousands
+	  with a single letter suffix added.  The modifier # when used with
+	  the i specification provides units of 1024 with a two letter suffix.
+06-10-24  The value of $! is now set to the process id of a job put
+	  into the background with the bg command as required by POSIX.
+06-10-23  A bug in which the value of $! was affected by a background
+	  job started from a subshell has been fixed.
+06-10-23  A bug in ${var:offset:len} in multibyte locales has been fixed.
+06-10-15  The remaining math functions from C99 were added for any system
+	  that supports them.
+06-10-13  The klockwork.com software detected a few coding errors that
+	  have been fixed.
+06-10-12  A bug when skipping over `...` with ${x:=`...`} when x is set
+	  has been fixed.
+06-10-11  A bug in process floating constants produced by the %a format
+	  of printf has been fixed.
+06-10-06  A bug in which IFS was not being restored correctly in some
+	  cases after a subshell has been fixed.
+06-10-06  A bug in which pipefail was not detecting some failures in
+	  pipelines with 3 or more states has been fixed.
+06-10-03  A bug in the processing of >(...) with builtins which could
+	  cause the builtin to hang has been fixed.
+06-10-03  A bug in the for loop optimizer which causes >(...) process
+	  substitution to be ignored has been fixed.
+06-09-17  The -a option was added to typeset for indexed arrays.  This
+	  is only needed when using the ([subscript]=value ...) form.
+06-09-06  The showme option was added.  Each simple command not beginning
+	  with a redirection and not occurring with in the while, until, if,
+	  select condition can be preceded by a semi-colon which will
+	  be ignored when showme is off.  When showme is on, any command
+	  preceded by a colon will be traced but not executed.
+06-08-16  As a new feature, a leading ~(N) on a pattern has no effect 
+	  except when used for file expansion.  In this case if not
+	  matches are found, the pattern is replaced by nothing rather
+	  than itself.
+06-08-11  A bug in the expansion of ${.sh.match[i]:${#.shmatch[i]}} has
+	  been fixed.
+06-08-10  The read builtin options -n and -N have been modified to treat
+          the size as characters rather than bytes unless storing into a
+	  binary (typeset -B) variable.
+06-07-27  When the here document operator << is followed directly by a #
+	  rather than a -, the first line of the here-document determines
+	  how much whitespace is removed for each line.
+06-07-26  A bug in the C-shell history (enabled with set -H) in which the
+	  history event !$ was not processed has been fixed.
+06-07-21  A bug on some systems in which assigning PATH on a command line
+	  would not take effect has been fixed.
+06-07-20  Add ksh93 and rksh93 as allowable names for ksh binaries.
+06-07-20  Removed the SHOPT_OO compilation option which was only partially
+	  implemented.
+06-07-20  The ability to use egrep, grep, and fgrep expressions within
+	  shell patterns has been documented.
+06-07-17  A bug with arithmetic command expressions for locales in which
+	  the comma is a thousands separator has been fixed. 
+06-07-13  The default HISTSIZE was increased from 128 to 512.
+06-07-13  A multibyte problem with locales that use shift codes has been fixed.
+06-06-23  A number of bug fixes for command, file, and variable completion
+	  have been mode.
+06-06-20  Floating point division by zero now yields the constant Inf or -Inf
+	  and floating functions with invalid arguments yield NaN. 
+06-06-20  The floating point constants Inf and NaN can be used in arithmetic
+	  expressions.
+06-06-20  The functions isinf(), isnan(), tanhl() have been added for
+	  arithmetic expressions.
+06-06-13  Internal change to use ordering for variables instead of hashing
+	  to speed up prefix matching.
+06-06-13  A window between fork/exec in which a signal could get lost
+	  and cause a program to hang has been eliminated
+06-06-13  A bug in edit completion with quoted strings has been fixed.
+06-06-07  The restricted options can now be enabled by set as well as on
+	  the command line.  Once set, it can not be disabled.
+06-06-04  Modified built-in binding so that for systems for which /bin
+          and /usr/bin are the same, a builtin bound to /bin will get
+	  selected when either /bin or /usr/bin is scanned.
+06-06-04  Added literal-next character processing for emacs/gmacs mode. 
+	  This change is not compatible with earlier versions of ksh93
+          and ksh88 when the stty lnext is control-v.  The sequence
+	  escape-control-v will display the shell version.
+06-05-31  Modified emacs and vi mode so that entering a TAB after a partial
+	  TAB completion, generates a listing of possible completions.
+	  After the second TAB, a number followed by a TAB will perform
+	  the completion with the corresponding item.
+06-05-19  Modified arithmetic so that conversions to strings default to
+	  the maximum number of precision digits.
+06-05-16  Bug fixes for multibyte locales. 
+06-05-10  The =~ operator was added to [[...]] and  [[ string ~= ERE ]]
+	  is equivalent to [[ string == ~(E)ERE ]].
+06-04-25  A bug in the vi edit mode which could cause the shell to core dump
+	  when switching from emacs mode.
+06-04-17  A bug in which using LANG or LC_ in assignment lists with builtins
+	  did not restore the localed correctly has been fixed.
+06-04-04  A bug in which discipline functions could not be added to variables
+	  whose names started with .sh has been fixed.
+06-03-28  The -s option to typeset was added to modify -i to indicate short
+	  integers.
+06-03-28  A bug in which variables assignment lists before functions
+	  defined with function name were not passed on the functions
+	  invoked by this function has been fixed. 
+06-03-28  A bug in which name references defined within a function defined
+	  with function  name could not be used with compound variables has
+	  been fixed.
+06-03-27  A bug in which read <&p (print >&p) would cause the coprocess input
+	  (output) pipe to close before reading from (after writing to)
+          it has been fixed.
+06-02-28  A bug in which stopping a job created with the hist builtin command
+	  would create a job that could not be restarted has been fixed.  
+
+06-01-24  --- Release ksh93r  ---
+06-01-24  A bug in which running commands with standard output closed would
+	  not work as expected has been fixed.
+06-01-23  A bug in which print -u<n> could fail when file descriptor <n> was
+	  open for writing has been fixed.
+06-01-19  The ?: arithmetic operator fixed to work when the operation after
+	  the colon was an assignment.
+05-12-24  A bug which could lead to a core dump when elements of a compound
+	  variable were array elements, i.e. foo=(bar=(1 2)), has been fixed.
+05-12-13  An arithmetic bug in which x+=y+=z was not working has been fixed. 
+05-12-13  An arithmetic bug in which x||y was returning x when x was non-zero
+	  rather than 1 has been fixed.
+05-12-07  The aliases for integer and float have been changed to use attributes
+	  -li and -lE to handle long long and long double types.
+05-12-07  The histexpand (-H) option has been added which allows C-shell
+	  style history expansions using the history character !.
+05-12-07  The multiline option was added which changes that way the edit
+	  modes handle lines longer than the window width.  Instead of
+	  horizontal scrolling, multiple lines on the screen are used.
+05-12-05  The whence builtin now returns an absolute pathname when the
+          command is found in the current directory.
+05-11-29  A bug which caused ksh -c '[[ ! ((' to core dump rather than
+	  report a syntax error has been fixed.
+05-11-29  A bug when reading fixed length records into typeset -b variables
+	  which caused a zero byte to terminate the value has been fixed.
+05-11-22  The ability to seek to an offset within a file has been added
+	  with the new I/O redirection operators, <#  and >#.  Currently,
+	  these redirection operators must be followed by ((expr))
+	  but in a future release, it should be able to used to seek forward
+	  to the specified shell pattern.  In addition $(n<#) expands to the
+	  current byte offset for file descriptor n.
+05-11-22  The .sh.match array variable is now set after each [[ ... ]]
+	  pattern match.  Previously it was only set for substring matches.
+05-10-17  A bug in which the library path variable could be prefixed
+          with a directory when a .path file was not encountered in
+	  the directory of the executable has been fixed.
+05-09-15  A for/while loop optimizer bug in which $OPTIND was not
+	  correctly expanded has been fixed.
+05-09-05  A bug in which a history command that invoked a history
+	  command could go into an infinite loop has been fixed.
+05-08-31  In the case that IFS contains to adjacent new-lines so that
+	  new-line is not treated as a space delimiter, only a single
+	  new-line is deleted at the end of a command substitution.
+05-08-19  When a tilde substitution expands to the / directory and is
+	  followed by a /, it is replaced by the empty string.
+05-08-16  A bug in which n<&m did not synchronize m has been fixed.
+05-08-16  A bug in which process substitution  ( <() and >() ) was not
+	  working within for and while loops has been fixed.
+05-07-24  A bug in which the pattern ~(E)(foo|bar) was treated as a syntax
+	  error has been fixed.
+05-07-24  A bug in completion with <n>=, where n was the one of the
+	  previous selection choices has been fixed.
+05-07-21  A bug with multibyte input when no edit mode was specified which
+	  caused the input line to shift left/right has been fixed.
+05-06-24  A race condition which could cause the exit status to get lost
+	  on some fast systems has been fixed.
+05-06-21  A bug in which nested patterns of the form {m,n}(pat) would cause
+	  syntax errors has been fixed.
+05-06-21  A bug in the macro expander has been fixed which could cause a
+          syntax error for an expansion of the form ${x-$(...)} when
+	  x is set and the command substitution contained certain strings.
+05-06-08  On systems for which echo does not do System V style \ expansions,
+	  the -e option was added to enable these expansion.
+05-06-08  A bug in which ${var op pattern} to not work when inside an
+	  arithmetic expression has been fixed.
+05-05-23  An extension to shell patterns that allows matching of nested
+	  groups while skipping over quoted strings has been added.
+05-05-18  A bug in which the line number for errors was not correct for
+          functions loaded from FPATH has been fixed.
+05-04-18  A bug in which the exit status $? is not set when a trap triggered
+	  by the [[...]] command is executed has been fixed.
+05-04-08  Redirection operators can be directly preceded with {varname}
+	  with no intervening space, where varname is a variable name which
+	  allows the shell to select a file descriptor > 10 and store it
+	  into varname.
+05-04-08  SHOPT_CMDLIB_BLTIN=1 now includes <cmdlist.h> generated table.
+05-04-07  [[ -o ?option ]] is true if "option" is a supported option.
+05-04-05  A bug in handling file completion with spaces in the names
+          has been fixed.
+05-03-25  The SIGWINCH signal is caught by default to keeps the LINES and
+	  COLUMNS variables in sync with the actual window size.
+05-03-25  Building ksh with SHOPT_REMOTE=1 causes ksh to set --rc if stdin is
+	  a socket (presumably part of a remote shell invocation.)
+05-03-25  Building ksh with SHOPT_SYSRC=1 causes interactive ksh to source
+	  /etc/ksh.kshrc (if it exists) before sourcing the $ENV file.
+05-03-25  {first..last[..incr][%fmt]} sequences added to brace expansions
+	  when braceexpand is enabled.
+05-03-03  A bug where a SIGCHLD interrupt could cause a fifo open to fail has
+	  been fixed.
+05-02-25  A bug in which a builtin command run in the background could
+	  keep a file descriptor open which could cause a foreground
+	  process to hang has been fixed.
+05-02-24  A bug where builtin library commands (e.g., date and TZ) failed to
+	  detect environment variable changes has been fixed.
+05-02-22  The read builtin and word splitting are now consistent with respect
+	  to IFS -- both treat IFS as field delimiters.
+05-02-22  The read builtin no longer strips off trailing delimiters that
+	  are not space characters when there are fewer variables than fields.
+05-02-17  A builtin bug on systems where dlsym(libcmd) returns link-time
+	  bindings has been fixed.
+05-02-12  A bug in which the lib_init() function for .paths BUILTIN_LIB
+	  libraries was not called has been fixed.
+05-02-06  A bug on some systems in which moving the write end of a co-process
+	  to a numbered file descriptor could cause it to close has been fixed. 
+05-02-06  A bug in the vi-edit mode in which the character under the cursor
+	  was not deleted in some cases with the d% directive has been fixed.
+05-02-06  A bug where external builtin stdout/stderr redirection corrupted
+          stdout has been fixed.
+05-02-04  A bug where times formatting assumed CLK_TCK==60 has been fixed.
+
+05-01-11  --- Release ksh93q  ---
+05-01-11  A bug in the integral divide by zero check has been fixed.
+05-01-11  The -l option has been added to read /etc/profile and
+	  $HOME/.profile, if they exist, before the first command.
+05-01-11  An argument parsing bug that caused `kill -s x -- n' to fail has
+	  been fixed.
+05-01-11  The .paths file, introduced in ksh93m, which can appear in
+	  any directory in PATH, now allows a line of the form 'BUILTIN_LIB=.'
+	  When a command is searched for this directory, and the full path
+	  matches the path of the built-in version of the command (listed
+	  by the 'builtin' command) then the built-in version of the command
+	  is used.  When ksh is built with SHOPT_CMDLIB_DIR=1 then all libcmd
+	  functions become builtins with the '/opt/ast/bin/' directory prefix.
+05-01-10  A bug in which a nameref to a compound name caused a core dump has
+	  been fixed.
+05-01-09  A bug in which some SIGCHLD interrupts (from child processes exiting)
+	  caused a fatal print/echo error diagnostic has been fixed.
+04-12-24  A bug in which some SIGCHLD interrupts (from child processes exiting)
+          corrupted the internal process/job list, sometimes causing the shell
+	  to hang, has been fixed.
+04-12-01  A bug in which typeset -Fn truncated less than n digits for large
+	  numbers has been fixed.
+04-11-25  A bug in which standard error could be closed after a redirection
+	  to /dev/stderr has been fixed.
+04-11-17  A bug in which an expansion of the form ${array[@]:3} could expand
+          to ${array[0]} when ${array[3]} was not set has been fixed.
+04-10-22  The -E or -orc command line option reads ${ENV-$HOME/.kshrc} file.
+04-10-22  `-o foo' equivalent to `+o nofoo', `-o nobar' equivalent to `+o bar'.
+          `--foo' equivalent to `-o foo', `--nofoo' equivalent to `+o foo'
+04-10-05  The .paths file, introduced in ksh93m, which can appear in
+	  any directory in PATH, now allows a line of the form
+	  'BUILTIN_LIB=libname'.  When a command is searched for this directory,
+	  the shared library named by libname will first be searched for a
+	  built-in version of the command.
+04-09-03  <<< here documents now handle quotes in the word token correctly. 
+04-08-08  The maximum size for read -n and and read -N was increased from
+	  4095 to 32M.
+04-08-04  printf %q was modified so that if an no operand was supplied, no
+	  no output would be generated rather than a quoted empty string.
+04-08-01  The -n and -N options of the read builtin has been modified
+	  when reading variables with the binary attribute so that the
+	  data is stored directly rather than through assignment.
+04-08-01  The shcomp command has been modified to process alias commands
+	  under some conditions.
+04-07-31  The .sh.match variable added in ksh93l, now works like other
+	  indexed arrays.
+04-07-08  A loop optimizer bug which occurs when typeset is used in
+	  a for or while loop inside a function has been fixed.
+04-06-24  The number of subexpressions in a pattern was increased to 64
+	  from the current number of 20.
+04-06-17  The -t option to read was modified to allow seconds to be
+	  specified as any arithmetic expression rather than just
+	  an integral number of seconds, for example even -t 'sin(.5)'
+	  is now valid.
+04-06-16  Two small memory leak problems were fixed.
+04-06-15  A bug in ${var/pattern/"string"} which occurred when string
+	  contained pattern matching characters has been fixed.
+04-05-08  printf $'%d\n' produced an erroneous error message and has
+	  been fixed.
+04-05-24  A bug in which an associative array without any elements could
+	  cause a core dump when a script with an associative array with
+	  the same name was declared in a script invoked by name has
+	  been fixed.
+04-05-11  A bug in which an exec statement could close the script that
+	  is being processed in a script that is run by name causing
+	  a failure has been fixed.
+04-04-28  If the first character of assignment to an integer variable was 0,
+          the variable had been treated as unsigned.  This behavior was
+          undocumented and has been removed.
+04-04-05  A bug in which the positioning of standard input could be incorrect
+	  after reading from standard input from a subshell has been fixed.
+04-03-30  A bug in the for loop optimizer which in rare cases could cause
+	  memory corruption has been fixed.
+04-03-29  The preset alias source='command .' has been added.
+04-03-29  A bug introduced in ksh93p on some systems in which invoked by
+	  name with #! on the first line would not get the signals handling
+	  initialized correctly has been fixed. 
+04-03-29  A bug introduced in ksh93p in which a HUP signal received by
+	  a shell that is a session group leader was not passed down to
+	  its children has been fixed.
+
+04-02-28  --- Release ksh93p  ---
+04-02-28  The ability to apply an append discipline to any variable has
+	  been added.
+04-02-14  A bug in which the exportall option (set -a) would cause incorrect
+	  results for arrays has been fixed.
+04-02-02  A bug in which an exported array would pass more than
+	  the first element to a script invoked by name has been fixed.
+04-02-02  A bug on some systems in which name=value pairs preceding a script
+	  invoked by name was not getting passed to the script has been fixed.
+04-01-20  A bug in which an unset discipline function could cause a core
+	  dump on some systems has been fixed.
+04-01-12  A bug in which a continue or break called outside a loop from
+	  inside a function defined with name() syntax could affect 
+	  the invoking function has been fixed.
+04-01-08  If a command name begins with ~, only filename completion will be
+	  attempted rather than pathname completion using the builtin editors. 
+04-01-08  A bug in the vi edit mode in which the wrong repeat count on
+	  multiple word replacements with the . directive has been fixed.
+04-01-06  Backspace characters are now handled correctly in prompt strings.
+04-01-06  The getopts builtin has been modified to accept numerical
+	  arguments of size long long on systems that support this.
+04-01-06  A bug in which unsetting all elements of an associative array
+	  would cause it to be treated as an indexed array has been fixed.
+03-12-15  A bug in which a quoted string ending with an unescaped $ would
+	  delete the ending $ in certain cases has been fixed.
+03-12-05  A bug in which the shell could hang when set -x tracing a command
+	  when an invalid multibyte character is encountered has been fixed. 
+03-12-05  On some systems, if the KEYBD trap is set, then commands that use
+	  the meta key were not processed until return was hit.  This
+	  has been fixed.
+03-12-05  A problem which occurred when the login shell was not a group
+	  leader that could cause it to fail has been fixed.
+03-12-05  A problem in which a shell could core dump after receiving a signal
+	  that should cause it to terminate while it was in the process
+	  of acquiring more space has been fixed.
+03-12-05  If ENV is not specified, the shell will default to $HOME/.kshrc
+	  for interactive shells.
+03-11-21  A bug introduced in ksh93o in which the DEBUG trap could get
+	  disabled after it triggered has been fixed. 
+03-11-04  A bug in which using arithmetic prefix operators ++ or -- on a
+	  non-lvalue could cause a core dump has been fixed.
+03-11-04  A bug in which leading zeros were stripped from variable
+	  expansions within arithmetic computation to avoid being treated

+03-10-08  A bug introduced in ksh93o in which a large here document inside
+	  a function definition could get corrupted has been fixed.
+03-09-22  A bug in which the .get discipline function was not being
+	  called when a string variable was implicitly referenced from
+	  within a numerical expression has been fixed.
+03-09-22  A bug in which a script without a leading #! could get executed
+	  by /bin/sh rather than the current shell on some systems has
+	  been fixed.
+03-09-12  To improve conformance with ksh88, leading zeros will be ignored
+	  when getting the numerical value of a string variable so that
+	  they will not be treated as octal constants.
+03-09-03  The builtin kill command now processes obsolete invocations
+	  such as kill -1 -pid.
+03-09-02  The restriction on modifying FPATH in a restricted shell (sh -r)
+	  has been documented.
+03-09-02  The restricted shell (sh -r) has been modified to disallow
+	  executing command -p.
+03-08-07  A bug in which the KEYBD trap was not being invoked when
+	  characters with the 8th bit set has been fixed.
+03-08-02  A parser bug introduced in ksh93o which caused the character
+	  after () in a Posix function definition to be skipped 
+	  when reading from standard input has been fixed.
+03-08-01  A bug in which "${foo#pattern}(x)" treated (x) as if it were
+	  part of the pattern has been fixed.
+03-08-01  The command -x option has been modified so that any trailing
+	  arguments that do expand to a single word will be included
+	  on each invocation, so that commands like command -x mv * dir
+	  work as expected.
+
+03-07-20  --- Release ksh93o+  ---
+03-07-20  A bug in which could cause memory corruption when a posix

+	  command substitution has been fixed.
+03-07-15  A parsing error for patterns of the form {...}(...) when
+	  used inside ${...} has been fixed.
+03-07-15  An error in which expanding an indexed array inside a compound
+	  variable could cause a core dump has been fixed.
+03-07-15  A bug in which under on rare occassions a job completion interrupt
+	  could cause to core dump has been fixed.
+03-06-26  A bug in which process substitution embedded within command
+	  substitution would generate a syntax error has been fixed.
+03-96-23  A bug in which ${@:offset:len} could core dump when there
+	  were no arguments has been fixed.
+03-96-23  A bug in which ${X[@]:offset:len} could core dump when X
+	  was unset has been fixed.
+03-06-22  The -x option was added to the command builtin.  If this
+	  option is on, and the number of arguments would exceed ARG_MAX,
+	  the command will be invoked multiple times with a subset of
+	  the arguments.  For example, with alias grep='command -x grep,
+	  any number of arguments can be specified.
+03-06-14  A bug in which could cause a core dump on some systems with
+	  vi and emacs editors with the MULTIBYTE option has been fixed.
+03-06-06  A bug in which the shell could core dump when a script was
+	  run from its directory, and the script name a symlink to a file
+	  beginning with .., has been fixed.
+03-06-05  A bug in which the shell could core dump when a child process
+	  that it is unaware of terminates while it is calling malloc()
+	  has been fixed.
+03-06-02  An option named globstar (set -G) has been added.  When enabled,
+	  during pathname expansion, any component that consists only of ** is
+	  matches all files and any number of directory levels.
+03-05-30  A bug in which the PATH search could give incorrect results when
+	  run from directory foo and PATH contained .:foo:xxx has been fixed.
+03-05-29  Some changes were made to the code that displays the prompt in edit 
+	  mode to better handle escape sequences in the prompt.
+03-05-27  I added = to the list of characters that mark the beginning of
+	  a word for edit completion so that filenames in assignments
+	  can be completed.
+03-05-20  A bug in which read -N could hang on some systems when reading
+	  from a terminal or a pipe has been fixed.
+03-05-19  A bug in which the output of uname from a command substitution
+	  would go to the standard output of the invoking command when
+	  uname was invoked with a non-standard option has been fixed.
+03-05-19  A job control bug which would cause the shell to exit because 
+	  it hadn't take back the terminal has been fixed.  The bug
+	  could occur when running a function that contained a pipeline
+	  whose last element was a function.
+03-05-19  A job control timing bug introduced in ksh93o on some systems
+	  which could cause a pipeline to hang if the first component
+	  completed quickly has been fixed.
+03-05-13  The read builtin has been modified so that the builtin editors
+	  will not overwrite output from a previous incomplete line. 
+03-05-13  A bug in which the name of an identifier could have the string
+	  .sh. prefixed to it after expanding a variable whose name begins
+	  with .sh. has been fixed.
+03-05-13  A bug in the expansion of $var for compound variables in which
+	  some elements would not be output when the name was a prefix
+	  of another name in the compound variable has been fixed.
+03-05-08  The last item in the ksh93o release on 03-01-02 has been
+	  altered slightly to preserve the leading 0's when the
+	  preceding character is a digit.  Thus, with typeset -LZ3 x=10,
+	  $(( 1$x)) will be 1010 whereas $(( $x) will be 10.
+03-04-25  A bug in which if x is a name reference, then nameref y=x.foo
+	  did not follow x has been fixed.
+
+03-03-18  --- Release ksh93o  ---
+03-03-18  A -N unary operator was added to test and [[...]] which returns
+	  true if the file exists and the file has been modified since it
+	  was last read.
+03-03-18  The TIMEFORMAT variable was added to control the format for
+	  the time compound command.  The formatting description is
+	  described in the man page.
+03-03-06  A -N n option was added to read which causes exactly n bytes
+	  to be read unlike -n n which causes at most n bytes to be read.
+03-03-03  Three new shell variables were added.  The variable .sh.file
+	  stores the full pathname of the file that the current command
+	  was found in.  The variable .sh.fun names the current function
+	  that is running.  The variable .sh.subshell contains the depth
+	  of the current subshell or command substitution.
+03-03-03  When the DEBUG trap is executed, the current command line after
+	  expansions is placed in the variable .sh.command.  The trap
+	  is also now triggered before each iteration of a for, select,
+	  and case command and before each assignment and redirection.
+03-02-28  Function definitions are no longer stored in the history file so
+	  that set -o nolog no longer has any meaning.
+03-02-28  All function definitions can be displayed with typeset -f not
+	  just those stored in the history file.  In addition, typeset +f
+	  displays the function name followed by a comment containing the
+	  line number and the path name for the file that defined this function.
+03-02-28  A bug in which the value of $LINENO was not correct when executing
+	  command contained inside mult-line command substitutions has been
+	  fixed.
+03-02-19  Since some existing ksh88 scripts use the undocumented and
+	  unintended ability to insert a : in front of the % and # parameter
+	  expansion operators, ksh93 was modified to accept :% as equivalent
+	  to % and :# as equivalent to # with ${name op word}.
+03-02-14  A bug which could cause a core dump when reading from standard
+	  error when standard error was a pty has been fixed.
+03-02-14  The shell arithmetic was modified to use long double on systems
+	  that provide this data type.
+03-02-09  A bug in which a function located in the first directory in FPATH
+	  would not be found when the last component of PATH was . and the
+	  current directory was one of the directories in PATH has been fixed.
+03-02-07  The trap and kill builtin commands now accept a leading SIG prefix
+	  on the signal names as documented.
+03-02-05  A bug in the expansion of ${var/$pattern}, when pattern contained
+	  \[ has been fixed.
+03-02-05  A bug in which .sh.match[n], n>0, was not being set for substring
+	  matches with % and %% has been fixed.
+03-01-15  A bug in which getopts did not work for numerical arguments specified
+	  as n#var in the getopts string has been fixed.
+03-01-09  A bug in which using ${.sh.match} multiple times could lead to
+	  a memory exception has been fixed.
+03-01-06  A bug in the expansion of ${var/pattern/$string} in the case that
+	  $string contains \digit has been fixed. 
+03-01-02  A -P option was added for systems such as Solaris 8 that support
+	  profile shell.
+03-01-02  For backward compatibility with ksh88, arithmetic expansion
+	  with ((...)) and let has been modified so that if x is a zero-filled
+	  variable, $x will not be treated as an octal constant.
+
+02-12-05  --- Release ksh93n+  ---
+02-11-30  A bug that can show up in evaluating arithmetic statements that
+	  are in an autoloaded function when the function is autoload from
+	  another function has been fixed.
+02-11-30  An optimization bug in which an expansion of the form ${!name.@},
+	  which occurred inside a for or a while loop, when name is a name
+	  reference, has been fixed.
+02-11-18  A bug in which modifying array variables in a subshell could leave
+	  side effects in the parent shell environment has been fixed.
+02-11-18  A memory leak when unsetting an associative array has been fixed.
+02-11-14  The code to display compound objects was rewritten to make
+	  it easier for runtime extensions to reuse this code.
+02-11-14  A change was made to allow runtime builtins to be notified when
+	  a signal is received so that cleanup can be performed.
+02-10-31  User applications can now trap the ALRM signal.  Previously,
+	  the ALRM signal was used internally and could not be used
+	  by applications. 
+02-10-31  A bug in which signals received while reading from a coprocess
+	  for which traps were set was not handled correctly has been fixed.
+02-10-31  A bug in which a file opened with exec inside a subshell could
+	  be closed before the subshell completed has been fixed.
+02-10-21  A bug in which setting PATH or FPATH inside a function might not
+	  take effect has been fixed.
+02-10-21  A bug which could cause a core dump when a local SECONDS variable
+	  is defined in a function has been fixed.
+02-10-15  A bug in which the associate array name operator ${!array[@]}
+	  could return the same name multiple times has been fixed.
+02-10-15  A bug in which the zero'th element of an associative array was
+	  not getting set when an assignment was made without a subscript
+	  specified has been fixed.
+
+02-09-30  --- Release ksh93n  ---
+02-09-30  The maximum indexed array size was increased to 16Megs.
+02-09-30  A bug which could cause a core dump when changing attributes
+	  of associative array has been fixed.
+02-09-30  A bug in which exporting an array variable would not export the
+	  0-th element has been fixed.
+02-09-30  A bug in which an array assignment of the form a=($a ...) would unset
+	  'a' before the right hand side was evaluated has been fixed.
+02-09-27  A bug in which the error message for ${var?message} when var was
+	  null or unset did not contain the variable name var has been fixed.
+02-09-27  A bug in which closing file descriptors 0 through 2 could
+	  cause a subsequent here document to fail has been fixed. 
+02-09-14  A bug in whence which occurs when the specified name contained
+	  a / has been fixed.
+02-09-14  A bug in the parser for strings of the form name$((expr))=value
+	  has been fixed.
+02-09-14  A for loop optimization bug in which the number of elements in
+	  an array was treated as an invariant has been fixed.
+02-09-09  A bug in which redirection or closing of a file descriptor between
+	  3 and 9 could cause a subsequent here document to fail has been
+	  fixed. 
+02-09-09  A bug in which a background job was not removed from the job list
+	  when a subshell completed has been fixed, for example (prog&). 
+02-09-03  A bug in which an assignment of the form name=(integer x=3)
+	  could be interpretted as an array assignment rather than a
+	  compound variable assignment has been fixed.
+02-08-19  A command completion bug which occurred on file systems that
+	  are case insensitive has been fixed.
+02-08-19  A bug which could lead to an exception on some systems (for
+	  example FREEBSD) which occurred when setting PATH has been fixed.
+02-08-11  A bug in arithmetic rounding in which a value input as a decimal
+	  string would output as a rounded version of the string has
+	  been fixed.
+02-08-11  A bug in which the last character could be deleted from shell
+	  traces and from whence when called from a multibyte locale
+	  has been fixed.
+02-08-01  A bug which could cause a core dump to occur when a shell script
+	  is executed while a coprocess is running that has closed the
+	  output pipe has been fixed.
+02-08-01  A bug in which command completion in multibyte mode could
+	  corrupt memory for long command lines has been fixed.
+
+02-06-17  --- Release ksh93n-  ---
+02-06-17  A bug in which user defined macros could cause a core dump in
+	  with MULTIBYE mode has been fixed.
+02-06-17  A bug in which printf format specifiers of the form %2$s were causing
+	  a core dump has been fixed.
+02-06-17  A bug in which setting stty to noecho mode did not prevent the
+	  echoing of characters by ksh when emacs or viraw mode
+	  was enabled has been fixed.
+02-06-17  A bug in which background job completion could cause the sleep
+	  builtin to terminate prematurely has been fixed.
+02-06-17  A bug in which the shell could core dump if getopts was called
+	  when the OPTIND variable contained a negative value has been fixed. 
+02-06-10  The edit mode prompt has been modified to handle escape sequences.  
+02-06-10  A bug which occurred for interactive shells in which the builtin
+	  cat command was used in command substitution on a file whose
+	  size was larger than PIPE_BUF has been fixed.
+02-06-10  A bug in which the trap on ERR was not being processed when
+	  set inside a function has been fixed.
+02-06-07  A bug in which function definitions could cause the history count
+	  to be decremented by one (and even become negative) has been fixed.
+02-06-05  A bug in read in which share mode could be enabled has been fixed.
+02-05-28  A bug which could occur when the last command of a script was
+	  a case statement and the action selected ended in ;& instead of ;;
+	  has been fixed.
+02-05-23  A bug with unary + introduced in ksh93k has been fixed.
+02-05-07  A bug in substitutions of the form ${var/pattern/string} in which
+	  a backslash was inserted in the replacement string when it contained
+	  a special pattern character has been fixed.
+02-05-01  A bug in the emacs edit mode which occurred in versions compiled
+	  for multibyte character sets which occurred when a repeated search
+	  was requested after a long line had been returned for the previous
+	  search has been fixed.
+02-04-02  vi and emacs edit modes were modified so that tab completion is
+	  disabled when invoked from the read built-in.
+
+02-03-26  --- Release ksh93m+  ---
+02-03-26  A bug in which \ was not handled correctly when used in file
+	  expansion has been fixed.
+02-02-18  A bug in which lines beginning with a # were deleted from here
+	  documents when the here-document delimiter was followed by
+	  a comment has been fixed.
+02-12-06  An optimization bug in which ${!x[@]) was treated as invariant in
+	  a for loop has been fixed.
+02-02-06  A bug in which the ERR trap is not cleared for a script invoked
+	  by name from within a function has been fixed.
+02-01-08  A bug in which a shell script executed from within a subshell
+	  could cause this script to have an invalid pointer leading
+	  to a memory fault has been fixed. 
+02-01-07  Added here documents of the form <<< word (as per zsh) which
+	  is equivalent to << delim\nword\ndelim.
+02-01-07  A bug in which the first word of a compound assignment,
+	  x=(word ...), was treated as a reserved word has been fixed.
+02-01-07  A bug in the handling of \ when noglob was enabled and a
+	  substitution of the form ${word op pattern} occurred in the
+	  same word has been fixed.
+02-01-07  A compilation option, CMDLIB_BLTIN in the file OPTION, has
+	  been added.  When this options is set, all commands implemented
+	  in libcmd become shell builtin commands by default.
+02-01-07  A bug in which builtin foo, where foo is already a builtin
+	  would result in the builtin foo getting removed has been fixed. 
+02-01-07  A bug which the shell executed a command found in the current
+	  directory when PATH have no valid directories has been fixed.
+01-11-28  The value of $? was not being set when called with exit.
+01-11-28  If the last command was of the form (...) and a trap on EXIT or
+	  ERR was set, and the command inside () modified the trap, then
+	  the original trap wasn't executed.
+01-11-26  The value for 0 is now preceded by the base number when
+	  the base was not 10.
+01-11-26  The default has compilation mode has been changes so that
+	  viraw mode will always be on.
+
+01-10-31  --- Release ksh93m  ---
+01-10-31  A for loop optimizer bug for subshells contained withing for
+	  loops has been fixed.
+01-10-16  typeset without arguments no longer outputs variable names
+	  that do not have any attributes that are set.
+01-10-16  A bug introduced in ksh93l in which assignments specified with
+	  the exec built-in were not being expanded properly has been
+	  fixed.
+01-10-11  An optimization bug in which ${!x) was treated as invariant in
+	  a for loop has been fixed.
+01-10-11  Unsigned integer variables in bases other than 10 are printed now
+	  expand in that base with the base prefix.
+01-10-10  A number of typos in the self generating man pages for shell
+	  built-ins have been fixed.
+01-10-04  The self generated man pages for hist and fc were not working
+	  correctly and have been fixed.

+01-09-27  Two bugs relating to multibyte history searches and to find
+	  have been fixed.
+01-09-27  A bug introduced in ksh93k in which the PATH searching was
+	  not restored after running a command with an assignment list 
+	  has been fixed.
+01-09-26  A bug in which a zero filled field was treated as octal when
+	  converted to integer has been fixed.
+01-09-26  Yet another bug in the optimization of for loops related to
+	  recursive functions with break or continue statements has been fixed.
+01-09-25  The exponentiation operator ** was added to the shell arithmetic
+	  evaluation.  It has higher precedence than * and is left
+	  associative.
+01-09-25  The code was modified to use the ast multibyte macros
+	  and functions for handing multibyte locales.
+01-09-25  The expansion ${parameter:offset:length} now handles negative
+	  offsets which cause offsets to be measured from the end.
+01-09-25  Some spelling errors in the documentation were corrected.
+01-09-24  The /dev/tcp/host/port and /dev/udp/host/port now allow
+	  the ports to be specified by service name. 
+01-09-24  The change staring with ksh93g in which the the appropriate
+	  library path variable is prepended with a corresponding library
+	  directory has been modified.  With the new method, only the
+	  library path defined in the file named .paths in the directory
+	  where the executable is found will be modified.  See the
+	  man page for more details.
+01-09-23  The .fpath file (see ksh93h) is no longer looked for in each
+	  directory on the path to locate function directories.  The
+	  file named .paths is used instead.
+01-09-23  A bug in which IFS was not being restored after being changed in
+	  a subshell has been fixed.
+01-09-16  With the vi and emacs edit modes, after a list of command
+	  or functions is generated with = or M-= respectively,
+	  any element from the list can be pasted on the command line
+	  by preceding the = or M-= with a numeric parameter specifying
+	  the position on the list.
+01-09-16  A bug in ksh93l caused command completion not to find aliases
+	  and functions.  Command listing from the edit mode was presented
+	  in reverse order.  This has been fixed.
+01-09-13  Another bug in the optimization of for loops related to subshells
+	  when traps were set has been fixed.
+01-09-07  A change in ksh93l caused brace expansion to stop working
+	  and this has been fixed.
+01-09-04  A bug introduced in ksh93k in which an arithmetic statement
+	  within a function that used name references did not follow the
+	  reference has been fixed.
+01-09-04  A bug introduced in ksh93l in which export -p did not prefix
+	  each export with the word export has been fixed.
+01-08-29  A bug in multibyte input which occurred when a partial multibyte
+	  character was received has been fixed.
+01-08-29  A bug introduced in ksh93l which could cause a core dump
+	  when an assignment list containing PATH is specified inside
+	  command substitution has been fixed.
+01-08-09  Another bug in the optimization of for loops in ksh93l caused
+	  errors in recursive functions using local variables that
+	  contained for loops has been fixed.
+01-07-27  A bug in which IFS would be unset after a command substitution
+	  inside a here document has been fixed.
+01-07-26  To conform to the POSIX standard, if you invoked ksh name,
+	  and name does not contain a /,  it will first try to run
+	  one in the current directory whether it is executable or not
+	  before doing a path search for an executable script.  Earlier
+	  versions first checked for an executable script using the
+	  PATH variable.
+01-07-23  A bug in which unset -f invoked in a subshell could unset a
+	  function defined in the parent has been fixed.
+01-07-16  A bug in the optimization of for loops in ksh93l caused
+	  name references to be treated as invariants has been fixed.
+01-07-09  A bug in which a discipline function applied to a local variable
+	  could cause a shell exception has been fixed.  Discipline
+	  functions can only be specified for global variables. 
+
+01-06-18  --- Release ksh93l  ---
+01-06-18  A bug in assigning integers larger than can be represented as
+	  long integers to floating point variables has been fixed.
+01-06-18  A bug in the handling of unsigned integers (typeset -ui) has
+	  been fixed.
+01-06-04  The evaluation of the PS1 prompt no longer effects the value
+	  of the $? variable.
+01-06-01  A small memory leak from subshells has been fixed.
+01-05-22  A bug in which attributes for variables that did not have
+	  values would be lost after a subshell has been fixed.
+01-05-22  The %R format has been added to convert a shell pattern into
+	  an extended regular expression.
+01-05-22  The escape sequences \e, \cX, \C[.collating-element.], and
+	  \x{hex} have been added to ASCII-C strings and to printf format
+	  strings.
+01-05-20  Patterns of the form {n}(pattern) and {m,n}(pattern) are now
+	  recognized.  The first form matches exactly n of pattern whereas,
+	  the second form matches from m to n instances of pattern.
+01-05-20  The shell allows *-(pattern), +-(pattern),  ?-(pattern),
+	  {m,n}-(pattern}, and @-(pattern) to cause the minimal
+	  match of pattern to be selected whenever possible rather
+	  than the maximal (greedy) match. 
+01-05-20  The character class [:word:] has been added to patterns.
+	  The word class is the union of [:alnum:] and the character _.
+01-05-20  Inside (...) pattern groups, the \ character is now treated
+	  specially even when in an enclosing character class.  The
+	  sequences, \w, \d, \s are equivalent to the character classes
+	  word, digit, and space respectively.  The sequences \W, \D,
+	  and \S are their complement sets. 
+01-05-20  The shell now recognizes pattern groups of the form
+	  ~(options:pattern) where options or :pattern can be omitted.
+	  Options use the letters + and - to enable and disable options
+	  respectively.  The option letters g (greedy), i (ignore case)
+	  are used to cause maximal matching and to cause case
+	  insensitive matching respectively.  If :pattern is also
+	  specified, these options are only in effect while this
+	  pattern is being processed.  Otherwise, these options remain
+	  in effect until the end of the pattern group that they are contained
+	  in or until another ~(...) is encountered.  These pattern groups
+	  are not counted with respect to group numbering.
+01-05-14  When edit completion, expansion, or listing occurs in the
+	  middle of a quoted string, the leading quote is ignored when
+	  performing the completion, expansion, or listing.

+	  for while and until loops.
+01-04-30  The variable .sh.match is set after each pattern match (# % or /)
+	  in a variable substitution.  The variable .sh.match is an
+	  indexed array with element 0 being the complete match. 
+	  The array is only valid until the next subsequent pattern
+	  match or until the value of the variable changes which ever
+	  comes first.
+01-04-30  A self generating man page has been added to shcomp.  Also,
+	  shcomp now stops compiling when it finds an exit or exec

+	  made by external commands such as stty which could
+	  effect the behavior of read.
+01-02-19  The -u, -g, and -k unary tests did not give the correct
+	  results when used with negation and this has been fixed.
+
+01-02-05  --- Release ksh93k+  ---

+          without recompilation.
+95-04-31  The name-value library interface has undergone significant
+          change for this revision.  See the new nval.3 man page.

+          The previous behavior was never documented.
+94-12-31  If IFS contains two consecutive identical characters belonging
+	  to the [:space:] class, then this character is treated as

+	  function was unset within a discipline was fixed.
+94-12-31  The typeset builtin now accepts a first argument of
+	  + or - for compatibility with ksh88.
+94-12-31  For compatibility with ksh88, the results of expansions
+	  of command arguments will treat the extended character
+	  match characters ()|& as ordinary characters.
+94-12-31  A bug which caused read to fail on a file that was
+	  open for read/write with <> when the first operation
+	  was print or printf has been fixed.

+	  the job list as required by the POSIX standard.
+94-12-31  The value of OPTARG when an option that required

+	  to terminate, rather than just return an error, has
+	  been fixed.
+94-12-31  Backreferencing sub-expressions in patterns and replacement
+	  strings now works.
+94-12-31  A bug in chmod which caused the -R option to fail has

+This is a list of changes that have been made since the 11/16/88 version
+of ksh.
+
+1.  New features in 12/28/93
+    a.	Associative arrays.  The new version of ksh supports both
+        associate arrays and the older indexed arrays with the same
+	array syntax.  A new -A option of typeset is used to declare
+	an array to be associative.  As with indexed arrays, $name is
+	equivalent to ${name[0]}.  The prefix operator ! was added
+	to the parameter expansion syntax to expand to the list of
+	indices.  For example, ${!name[@]} expands to the list of array
+	indices for variable name.
+
+    b.	Several additions have been made to shell arithmetic:
+	1.  The shell now performs floating point arithmetic.  The
+	    typeset options -F and -E have been added for floating
+	    point and scientific notation respectively.
+	2.  The prefix and postfix ++ and -- operators.
+	3.  The comma and ?: operators.
+	4.  The math library functions.
+	5.  An arithmetic for statement of the form
+		for ((expr1; expr2; expr3))
+		do	...
+		done
+	6.  Integer arithmetic extended up to base 64.
+
+    c.  Some additions to the macro expansion syntax have been made
+	to specify substrings and sub-arrays:
+	1.  ${name:expr} expands to the substring of ${name} starting at
+	    the character position defined by arithmetic expression expr.
+	2.  ${name:expr1:expr2} expands to the substring of ${name} starting
+	    at expr1 and consisting of at most expr2 characters.
+	3.  ${name[@]:expr} expands to the values of ${name[@]} starting at
+	    the element defined by arithmetic expression expr.
+	4.  ${name[@]:expr1:expr2} expands to at most expr2 values of
+	    ${name} starting at expr1.
+	5.  ${@:expr} expands the positional parameters starting at expr.
+	6.  ${@:expr1:expr2} expands to at most expr2 positional parameters
+	    starting at expr1.
+	7.  ${!name} expands to the name of the variable named by name.
+	    It will expand to name unless name is reference variable.
+	8.  ${!name[sub]} expands to the name of the subscript of the
+	    given variable.  If sub is @ or * the list of subscripts
+	    is generated.
+	9.  ${!prefix*} and ${!prefix@} expand to the list of variable
+	    names beginning with prefix.
+	10. The substring operators, # and % can be now be applied
+	    with aggregates (@ or *) and are applied to each.
+	11. ${name/pattern/string} expands to the value of name with
+	    the first occurrence of pattern replaced by string.
+	    With aggregates (@ or *) this operation is applied to each.
+	12. ${name/#pattern/string} Same as above but the pattern
+	    to be replaced must match at the beginning.
+	13. ${name/%pattern/string} Same as above but the pattern
+	    to be replaced must match at the end.
+	14. ${name//pattern/string} expands to the value of name with
+	    the each occurrence of pattern replaced by string.
+	    With aggregates (@ or *) this operation is applied to each.
+
+    d.  The name space for variables has been extended.  The character '.'
+	can be used at the beginning of a name, and to separate identifiers
+	within a name.  However, to create a name of the form, foo.bar,
+	the variable foo must exist. The namespace starting with .sh
+	is reserved for shell implementation variables.  Exported
+	variable cannot contain a '.'.
+
+    e.  Compound assignments.  The assignment syntax, varname=value,
+	has been extended to allow assignments of the form
+	varname=(assignment_list).  As elsewhere in the shell
+	spaces or tabs are optional around the parentheses, and
+	no space is permitted between the varname and the =.  The
+	assignment_list can be one of the following:
+	1.  A list of words.  In this case each word is expanded as
+	    in a for list and the resulting items become elements
+	    of the indexed array varname. 
+	2.  A list of subscript assignments in the form
+	    [subscript]=value.  In this, these elements become 
+	    elements of the associative array varname. 
+	3.  A list of assignments; simple or compound.  In this
+	    case, each assignment is made to varname.name, where
+	    name is the name of the enclosed assignment.
+	4.  Assignments in the form of readonly or typeset
+	    statements.  In this case each assignment is made as
+	    in 3 above, and the attributes are given to the
+	    corresponding variable.
+	In case 3 and 4 above, the value of "$varname" after
+	the above assignment is (assignment_list), where the
+	assignment_list produced would reproduce all of the
+	variables under varname.*.
+
+    f.  Function names of the form variable.action (called discipline
+	functions) can be defined where variable is any valid variable
+	name and action is get, set, or unset.  The function variable.get
+	is invoked each time the variable is referenced.  The set
+	discipline is invoked each time the variable is assigned to.
+	The unset discipline is invoked when a variable is unset.
+	The new variables .sh.name, .sh.subscript, and .sh.value are
+	defined inside the function body.  Other shell extensions
+	may have their own set of discipline functions.
+
+    g.	The compound command !, which negates the return value of the
+	following pipeline, has been added.
+
+    h.	On systems that support dynamic loading with dlopen(), it is
+	now possible to add built-in commands at runtime with the
+	a builtin command named builtin. 
+
+    i.	The following builtins have been added:
+	1.  command name [ ... ]
+	2.  sleep [decimal-seconds]
+	3.  builtin [-ds] [-f file] [name...]
+	4.  getconf name [pathname]
+	5.  disown [job...]
+
+    j.	An addition format for literal strings, $'....' can
+	be used where ever literal strings are valid.  The string
+	inside the single quotes will be converted using the ANSI-C
+	escape conventions.  Additionally, the escape sequence \E
+	expands to the escape character (default \033) whenever ANSI-C
+	escape sequences are recognized.
+
+    k.  A typeset -n option has been added which causes the value of a
+	variable to be treated as a reference to another variable so that
+	variables can be indirectly named.  For example, if $1 contains
+	the name of a variable, then typeset -n foo=$1 causes the variable
+	foo to be synonymous with the variable whose name is $1.  A builtin
+	alias, nameref='typeset -n' has been added to aid mnemonics.
+	Reference names cannot contain a '.'.  Whenever that portion of
+	a variable up to the first '.' matches a reference name, the
+	reference value is substituted.  For example, with nameref foo=.top,
+	then ${foo.bar} is equivalent to ${.top.bar}.  When used as the
+	index of a for or select loop, each assignment causes a
+	new name reference to occur.
+	
+    l.	The KEYBD trap has been added which is triggered when a key
+	or escape sequence is typed while reading from the keyboard
+	in an edit mode.  This, combined with some new variables
+	makes it possible to program your key bindings in ksh.
+
+    m.	New variables have been added:
+	1.  FIGNORE defines a set of file names to be ignored in each
+	    directory when performing pathname expansion, replacing
+	    the rule that requires that a leading . be matched explicitly.
+	2.  Variable sh.edchar contains the value of the keyboard character
+	    that has been entered when processing a KEYBD trap.  If the value
+	    is changed as part of the trap action, then the new value replaces
+	    the key or keys that caused the trap.
+	3.  Variable sh.edcol is set to the character position of the cursor
+	    within the input buffer during a KEYBD trap.
+	4.  Variable sh.edmode is set to the escape character when in vi
+	    insert mode.
+	5.  Variable sh.edtext is set to the contents of the input buffer
+	    during a KEYBD trap.
+	6.  HISTEDIT is checked before FCEDIT.  FCEDIT is obsolete.
+	7.  HISTCMD is the number of the current command in the history
+	    file.
+	8.  Variable .sh.version is set to the version string for
+	    this shell.
+	9.  Variable .sh.name is set to the name of the variable
+	    that that was referenced or assigned to when executing a get
+	    or set discipline function.
+	10. Variable .sh.subscript is set to the subscript for the variable
+	    that was referenced or assign to when executing a get or
+	    set discipline function.
+	11. Variable .sh.value is set to the new value for the variable
+	    that was assigned to when executing the set discipline function.
+
+    n.	New invocation and set -o options have been added:
+	1.  set -o notify (or set -b) causes background completion messages
+	    to be displayed as soon as the job completes.
+	2.  There is a compile time option named KIA which enables
+	    creation of a relational database for commands, variables
+	    and functions defined and referenced by a script.  The
+	    option -I <filename>, causes the database to be generated
+	    in <filename>.  The database format can be queried via
+	    the cql command.
+    o.	ksh93 can read and evaluate pre-compiled scripts generated by
+	a separate program called shcomp.
+    p.  More work on internationalization has been added:
+	1.  The decimal point character is processed per locale
+	2.  A $  can be placed in front of each string to indicate
+	    that the string needs translation but is otherwise ignored.
+	    This means that if a message catalog of all $"..." strings
+	    is generated, then a program such as print $"hello world"
+	    could display "bonjour monde" in the french locale.
+    q.	Backreferences have been added to pattern matching.  The sequence
+	\d, where d is a digit from 1-9, matches the same string as
+	the d-th previous parenthesis group.  Backreferences
+	can be used within patterns, and within replacement strings
+	with any of the ${name/...} operators.
+
+2.  Changes made in 12/28/93
+    a.	The output format of many commands has changed as follows:
+	1.  System error messages are displayed whenever a failure
+	    is caused by a system call.
+	2.  The exit status has changed in many cases:
+	    a.	USAGE messages cause an exit status of 2.
+	    b.	Commands not found cause exit - 127.
+	    c.	Command found, but not executable - 126.
+	    d.	Terminated because of signal -	256+sig
+	3.  The output of values from built-ins that contain special
+	    characters are quoted in a manner that then can be re-input.
+	4.  The trace output puts quotes around the output so that it
+	    can be reused as input.
+	5.  The output for trap is in a format that can be reinput the
+	    the shell to restore the traps.
+	6.  kill -l lists the signal names without numbers as
+	    required by the POSIX standard.
+
+    b.	The following changes have been made to shell functions:
+	1.  The semantics of functions declared with name() has changed
+	    to conform with the IEEE-POSIX 1003.2 standard.  In particular,
+	    these functions are executed in a dot script environment rather
+	    than a separated function environment so that there are no
+	    local variables and no scoping for traps.
+	2.  Functions declared as function name, preserve the old ksh
+	    semantics can be also used as the first argument to the dot (.)
+	    command to have them executed in a dot script environment.
+	
+    c.	The command search rules have changed as follows:
+	1.  Special built-ins (those with a dagger in front of them) are
+	    executed first.
+	2.  Functions are executed next.
+	3.  Other built-ins that do not require an executable version
+	    (for example cd and read) come next.
+	4.  If the command name contains a slash, the pathname corresponding
+	    to the command name is executed.
+	5.  If name corresponds to a previously encountered pathname
+	    on the PATH variable, the corresponding command is executed.
+	6.  If the command name does not contain a slash, then the PATH
+	    variable is used to find an executable by that name.  If
+	    the directory that the command is found is also contained in
+	    the FPATH variable, then the command treated as a function.
+	    If the shell has a built-in version of the command corresponding
+	    to this command, then the built-in version of this command
+	    is executed.  Otherwise, the shell remembers that pathname
+	    corresponding to this command name and executes this pathname.
+	7.  If the name is not found on PATH, then the directories in
+	    FPATH are searched.  If found, then the command is executed
+	    as a function.
+
+    d.	Built-in commands options now conform to the IEEE-POSIX 1003.2
+	conventions with some additions.  In particular,
+		name -?
+	will now print a Usage line for name, except for true, false,
+	colon, login, newgrp, echo, [, and command.
+
+    e.	Tilde expansion is now performed as part of the word expansions.
+	The effect of this is that if word begins with ~ in ${name op word},
+	it will be expanded unless escaped.
+
+    f.  Pathname expansion is no longer performed on redirection words
+	unless the shell is interactive.
+
+    g.	Changes to shell and options:
+	1.  The -n option has been enhanced to produce more warning and
+	    portability messages.
+	2.  The -C option is equivalent to -o noclobber.  Files are
+	    created with O_EXCL when -C is on.
+
+    h.	The following changes have been made to [[...]]:
+	1.  A string by itself is equivalent to -n string.
+	2.  -e has been added as equivalent to -a.
+	3.  == has been added as equivalent =.
+	4.  -a and = are now considered obsolete.
+	5.  Arithmetic comparisons are now considered obsolete.
+
+    i.	kill has been changed as follows:
+	1.  Signal names can be upper case or lower case.
+	2.  Numerical arguments to kill -l cause the given signal names to
+	    be displayed.
+	3.  String arguments to kill -l cause the given signal numbers to
+	    be displayed.
+	4.  Synopsis changed for getopts conformance.
+
+    j.	print has a -f format option which is equivalent to
+	the IEEE POSIX printf.  Both print -f format, and
+	printf have the following extensions from IEEE POSIX:
+	1.  Floating point formats are supported.
+	2.  Size and precision specifications can be *.
+	3.  The %d option can take an argument after precision to
+	    specify the base that the number will be displayed.
+	4.  A %q format can be used to output a string quoted so
+	    that it can be re-input to the shell.
+	5.  A %P format can be used to output the shell pattern which
+	    corresponds to the give extended regular expression.
+	6.  For numerical fields, the arguments can be arithmetic
+	    expressions which will be evaluated.
+	7.  The %n format works as described in ANSI-C.
+
+    k.	The following changes have been made to fc:
+	1.  It has been renamed hist.  fc is now a predefined alias.
+	2.  hist uses ${HISTEDIT:-$FCEDIT}.  FCEDIT is obsolete.
+	3.  A new -s option is equivalent to the obsolete -e -.
+	4.  If the first argument refers to a command earlier than the
+	    first accessible command, it now implies the first accessible
+	    command, so that hist -l 1 lists all accessible history commands.
+
+    l.	The dot command (.) has changed as follows:
+	1.  The argument can be the name of a function declared as
+	    function name.  The function will execute without creating a
+	    new scope.
+	2.  If there are arguments to the given script or function,
+	    the positional parameters are restored to their original
+	    value when . completes.
+
+    m.  The read built-in has been changed as follows:
+    	1.  A -A option to read has been added to allow the fields to be
+	    read into an indexed array.
+	2.  A -t n option has been added which causes read to
+	    timeout after n seconds when reading from a slow device.
+	3.  A -d char option has been added which causes the read
+	    to terminate at char rather than at new-line.
+	
+    n.	The trap command has been changed as follows:
+	1.  Trap names can be either upper case or lower case.
+	2.  Trap -p cause only the specified trap values to be displayed. 
+	3.  The value of trap in a subshell will be the value in the parent
+	    shell until a call to trap which changes the trap settings has
+	    been made.  Thus, savetraps=$(trap) works as required by the
+	    POSIX standard.
+
+    o.  The exec command has been extended as follows:
+	1.  The -c option clears the environment first.
+	2.  The -a name option sets argv[0] to name for the program.
+
+    p.	true and false are built-ins, not aliases to built-ins.
+
+    q.	test has been modified to conform to the IEEE-POSIX 1003.2
+	standard when there are three or less arguments.
+
+    r.	umask -S option displays the mask in a symbolic format.
+
+    s.	wait now returns the correct exit status of any previous
+	background job that has not been waited for, not just
+	the most recent one.
+
+    t.  The whence built-in has an option -a which causes all
+	uses for the given command name to be reported.
+
+    u.  unalias has -a option to clear all the aliases.
+ 
+    v.	The times built-in command has been removed.  The time
+	reserved word, without a command, gives time cumulative
+	time for the shell and its children.  A built-in alias
+	for times should enable scripts using times to continue
+	to run.
+
+    w.	Command substitution and arithmetic substitution will now be
+	performed for PS1, ENV, and PS4 evaluation in addition to
+	parameter expansion.
+
+    x.  The SECONDS variable now displays elapsed time in floating
+	point seconds with 3 places after the decimal point by
+	default.
+
+    y.  The getopts built-in now handles the complete libast optget
+	functionality.  If any errors have occurred with getopts
+	when it has reached the end of arguments, then the Usage
+	message will be generated from the option string and the
+	exit status from getopts will be 2 rather than 1.  The
+	usage message will be stored in the OPTARG variable if
+	the option string contains a leading colon; otherwise
+	it will be printed on standard error automatically.
+
+    z.	THE ENV file is only processed for interactive shell
+	invocations.  In addition, the -x attributes for
+	aliases and functions is ignored.
+
+    aa. The built-in edit modes have been changed as follows:
+	1. The pathname completion and pathname listing options
+	   now perform command completion and command listing
+	   when applied to a word in the command position.
+	2. In emacs mode ^N as the first related command after
+	   the prompt will move to the next command relative to the
+	   last known history position.
+	3. In emacs mode, successive kill and delete commands will
+	   accumulate their data in the kill buffer, by appending or
+	   prepending as appropriate.  This mode will be reset by any
+	   command not adding something to the kill buffer.
+	4. The control-T of emacs mode has been changed to behave like
+	   control-T in gnu-emacs.
+    bb. The TMOUT variable also sets a limit for select timeouts
+	and default timeouts for read.
+
+
+4.  The source code has undergone significant modification.
+    a.	Much of the code has been rewritten,  In many cases this has
+	resulted in significant performance improvement.
+
+    b.  The code is organized differently.  See the README files
+	for more details.
+
+    c.	Most configuration parameters now get generated using
+	the FEATURE mechanism of nmake.  Other options are set
+	in the OPTIONS file.
+
+    c.	The are several new compile time options. See the README
+	file for details.  Some of the old ones have been removed.
+
+    d.	The install script is a Mamfile that is generated by
+	nmake and processed by a script that comes with the
+	distribution.
+
+    e.	There are far fewer global names.  This should make it
+	must easier to add built-in commands without worrying
+	about conflicts.
+		
+    f.	The code uses the sfio library which makes it possible
+	to mix with stdio.
+
+    g.	The code is written in ANSI C with full prototypes.
+	The code is based on the IEEE POSIX 1003.1 standard.
+	The code can be compiled with K&R C and with C++ by
+	using the ANSI cpp that comes with nmake or running
+	the code through the proto filter before pre-processing.
+	This happens automatically with our shipping system.
+
+    h.  There is a programming interface for capturing references
+	and assignment to shell variables.  It is also possible
+	to intercept variable creation and supply the array processing
+	function for that variable.  See nval.3 for a description.

+This is a list of changes that have been made since the 12/28/93 version
+of ksh. 
+
+1.	New features in 12/28/93b
+	a.  If IFS contains two consecutive identical characters belonging
+	    to the [:space:] class, then this character is treated as
+	    a non-space delimiter so that each instance will delimit
+	    a field.  For example, IFS=$'\t\t' will cause two consecutive
+	    tabs to delimit a null field.
+	b.  The getopts command has a -a name option that specifies a
+	    name that will be used for usage messages.
+
+2.	New features in 12/28/93e
+	a.  The math functions, atan2, hypot, fmod, and pow were added.
+	b.  When a shared library is loaded, if the function lib_init()
+	    is defined in the library, it is invoked the first time that
+	    the library is loaded with builtin -f library.
+
+3.	New features in 12/28/93f
+	a.  Hostnames in addition to host addresses can be given in
+	    /dev/tcp/host/port virtual file names.
+	b.  File name completion and expansion now quotes special
+	    characters in file names from both emacs and vi edit modes.
+
+4.	New features in 12/28/93g
+	a.  The pipefail option has been added.  With pipefail
+	    enabled, a pipeline will not complete until all
+	    commands are complete, and the return value will
+	    be that of the last command to fail, or zero if
+	    all complete successfully.
+	b.  When an executable is found on a given path,
+	    the appropriate library path variable is prepended
+	    with a corresponding library directory.
+5.	New features in 12/28/93h
+	a.  The PATH search algorithm has been modified to look
+	    for a file named .fpath in each bin directory and if
+	    found, to search for functions in this directory if
+	    it cannot find the command in that directory.
+	b.  When performing pathname expansion, the shell checks
+	    to see whether each directory it reads is case sensitive
+	    or not, and performs the matching accordingly.
+	c.  The %T format for printing formatted date/time.
+6.	New features in 12/28/93i
+	a.  Most of the built-in commands and ksh itself are now
+            self documenting.  Running command --man will produce
+            screen output.  Running command --html produces the
+            man page in html format.
+	b.  The getopts builtin can process command description
+            strings to produce man pages.
+
+7.	Bugs fixed in 12/28/93a for default OPTIONS
+	a.  An expansion bug which causes portions of a word after
+	    a $((...)) expansion that contains a nested $var expansion
+	    to be lost has been fixed.
+	b.  A bug that caused a core dump when a script that did not
+	    have PWD set and did a cd inside command substitution
+	    has been fixed.
+	c.  A bug which caused a core dump on some machines when
+	    the LANG variable was assigned to has been fixed.
+	d.  A bug which incorrectly handled set disciplines that
+	    performed arithmetic evaluation when the discipline
+	    was called from the arithmetic evaluator has been fixed.
+	e.  A bug caused by an EXIT trap inside a function that
+	    was executed in a subshell was fixed.
+	f.  If foo is a function, and not a program, then command foo
+	    now reports that foo isn't found rather than invoking foo.
+	g.  The previous version incorrectly listed -A as an
+	    invocation option.  The -A option is only for set. 
+	h.  A bug was fixed which caused ksh to loop when execution trace
+	    was enabled and the PS4 prompt required command substitution.
+	i.  A bug which could cause the job control switch character
+	    to be disabled when a script that enabled monitor mode
+	    terminated was fixed.
+	j.  A bug in the macro expansion global replacement operator //,
+	    when the pattern began with a [ or +( has been fixed.
+	k.  A bug which prevented ~ expansion from occurring when
+	    it was terminated with a colon inside an assignment
+	    has been fixed.
+	l.  A bug in the dot command which prevented autoload functions
+	    from working has been fixed.
+	m.  A bug which caused a variable to be unset if the
+	    its value were expanded inside a set discipline has
+	    been fixed.
+	n.  Whence -a now longer reports that a defined function
+	    is undefined.
+	o.  A bug on some systems in which $0 would be incorrect
+	    in scripts invoked by name has been fixed.
+	p.  Here documents with an empty body now work.
+	1.  A bug which disabled argument passing and resetting
+	    of options for a script invoked by name inside a
+	    function has been fixed.
+	r.  A bug in which an EXIT trap set the caller of a function
+	    would be executed if a command called inside a function
+	    was not found has been fixed.
+	s.  A bug which allowed a script to trap signals that are
+	    ignored at the time that the shell was invoked has
+	    been fixed.
+	t.  A bug which caused 2<&1- when applied to a shell built-in
+	    to leave standard input closed has been fixed.
+	u.  A bug which caused the shell to incorrectly parse
+	    $() command substitutions with nested case statements
+	    has been fixed.
+
+8.	Bugs fixed in 12/28/93b for default OPTIONS
+	a.  A bug which caused unset RANDOM to dump core has been
+	    fixed.
+	b.  A bug which prevented return for terminating a profile
+	    or ENV file has been fixed.
+	c.  A bug which prevented standard input from being
+	    directed to /dev/null for background jobs when
+	    monitor mode was turned off has been fixed.
+	d.  Statements of the form typeset -options var[expr]=value
+	    did not perform substitutions on expr as expected.
+	e.  A bug which prevented the shell from sending a HUP
+	    signal to some background jobs that were not disowned
+	    has been fixed.
+	f.  A bug which allowed a script to trap signals that are
+	    ignored at the time that the shell was invoked by exec
+	    has been fixed.
+	g.  A bug which could cause a core dump when a discipline
+	    function was unset within a discipline was fixed.
+	h.  The typeset builtin now accepts a first argument of
+	    + or - for compatibility with ksh88.
+	i.  For compatibility with ksh88, the results of expansions
+	    of command arguments will treat the extended character
+	    match characters ()|& as ordinary characters.
+	j.  A bug which caused read to fail on a file that was
+	    open for read/write with <> when the first operation
+	    was print or printf has been fixed.
+	k.  When a job is suspended, it is put on the top of
+	    the job list as required by the POSIX standard.
+	l.  The value of OPTARG when an option that required
+	    an argument but didn't have one was incorrect in the
+	    case the the option string began with a :.
+	m.  A bug which caused the terminal to get into a bad
+	    state with some KEYBD traps in vi-mode has been fixed.
+	n.  A bug which caused an invalid trap to cause a script
+	    to terminate, rather than just return an error, has
+	    been fixed.
+	o.  Backreferencing sub-expressions in patterns and replacement
+	    strings now works.
+	p.  A bug in chmod which caused the -R option to fail has
+	    been fixed.

+9.	Bugs fixed in 12/28/93c for default OPTIONS
+	a.  The expansion of "$@" was incorrect when $1 was the null
+	    string.
+	b.  A bug which could incorrectly report a syntax error in
+	    a backquoted expression when a $ was preceded by \\
+	    has been fixed.
+	c.  A bug which prevented the shell from exiting after
+	    reporting an error when failing to open a script
+	    has been fixed.
+	d.  A bug that could lead to memory corruption when a
+	    large here document that required parameter or command
+	    substitution was expanded has been fixed.
+	e.  A bug that could cause a core dump on some systems
+	    after ksh detected an error when reading a function
+	    has been fixed.
+	f.  A bug which could cause a coprocess to hang when
+	    reading from a process that has terminated has been fixed.
+	g.  A bug which caused a script to terminate when set -e
+	    was on and the first command of and && or || list
+	    failed has been fixed.
+	h.  A bug with here documents inside $(...) when the delimiter
+	    word is an identifier has been fixed.
+	i.  A bug which caused $0 to display the wrong value when
+	    a script was invoked as an argument to the . command
+	    and the eval command has been fixed.
+	j.  A bug that could cause the built-in sleep to hang
+	    has been fixed.
+	k.  A bug introduces in 12/28/93b which caused the backslash
+	    to be removed when it was followed by digit inside double
+	    quotes in some instances has been fixed.
+	l.  A bug which could cause a core dump if ksh was invoked with
+	    standard input closed has been fixed.
+	m.  A bug which could cause a core dump if typeset -A was
+	    specified for an existing variable has been fixed.
+	n.  Variables that were unset but had attributes such as readonly
+	    and export were not listed with readonly, export and typeset.
+	o.  Several problems with signals have been fixed.
+	p.  A bug which prevented ulimit -t from working has been fixed. 
+	    Also, a bug in which failed ulimits could cause a core dump
+	    has also been fixed.
+	q.  A bug in expansion of the form ${name/#pattern/string} and
+	    ${name/%pattern/string} has been fixed.
+	r.  A bug which caused read -r on a line that contained only
+	    blanks to get a non-null value has been fixed.
+	s.  A bug introduced in the 'a' point release in which
+	    ${x='\\'} expanded to \ when x was unset has been fixed.
+	t.  A bug which prevented a trap on EXIT from being executed
+	    when the last command in a script was a function invocation
+	    has been fixed.
+	u.  A bug which caused an interactive shell ignore input when
+	    standard error was redirected to a file with exec,
+	    and then restored with exec 2>&1 has been fixed.
+	v.  An interactive shell turns on monitor mode even when
+	    standard error has been redirected to a file.
+	w.  A bug which could cause standard input to be incorrectly
+	    positioned for the last command of a script has been fixed.
+	y.  A bug in the edit modes which allowed walking back in
+	    the history file for more than HISTSIZE commands has
+	    beed fixed.
+	z.  A bug which could cause a core dump if variable TMPDIR was
+	    changed between two command substitutions has been fixed.
+	aa. A bug which prevented a trap on EXIT from being cleared
+	    has been fixed.
+
+10.	Bugs fixed in 12/28/93d for default OPTIONS
+	a.  The \ character was not handled correctly in replacement
+	    patterns with ${x/pattern/replace}.
+	b.  A bug with read in which the line did not end with
+	    a new-line has been fixed.
+	c.  A bug in file name generation which sometimes
+	    appended a . for filenames that ended in / has
+	    been fixed.
+	d.  If a process is waited for after a status has
+	    been returned by a previous wait, wait now
+	    returns 127.
+	e.  A bug with hist (fc) -e which prevented a command
+	    to re-executed after it had been edited has been fixed.
+	f.  A bug which prevented quoting from removing the meaning
+	    of unary test operators has been fixed.
+
+11.	Bugs fixed in 12/28/93e for default OPTIONS
+	a.  Empty command substitutions of the form $() now work.
+	b.  whence -v foo now gives the correct result after calling
+	    builtin -d foo. 
+	c.  A bug in right to left arithmetic assignment for which
+	    the arithmetic expression (( y = x = 1.5 )) did not
+	    yield 1 for y when x was declared typeset -i was fixed.
+	d.  printf has been fixed to handle format  containing \0
+	    and/or \0145 correctly.  In addition, characters following
+	    %b in the format string are no longer displayed when
+	    the operand contains \c.
+	e.  A bug in printf that could cause the %E format to
+	    produce unnormalized results has been fixed.
+	f.  A bug which causes some arithmetic expressions to be
+	    incorrectly evaluated as integer expressions rather
+	    that floating point has been fixed.
+	g.  Functions defined inside a subshell no longer remain
+	    defined when the subshell completes.
+	h.  The error message from sh -c ';echo foo' has been
+	    corrected.
+	i.  The format for umask -S has been changed to agree
+	    with the specification in the POSIX standard.
+	j.  A bug that caused side effects in subscript evaluation
+	    when tracing was enabled for subscripts using ++ or --
+	    has been fixed.
+	k.  To conform to the Posix standard getopts has been changed
+	    so that the option char is set to ? when it returns with
+	    a non-zero exit status.
+	l.  The handling of \} inside ${name...} has been fixed so
+	    that the \ quotes the }.
+	m.  A bug that caused the read builtin to resume execution
+	    after processing a trap has been fixed.
+	n.  [[ -s file ]] has been fixed so that if file is open
+	    by ksh, it is flushed first.
+	o.  In some cases attributes and sizes for non exported
+	    variables weren't being reset before running a script.
+	p.  The value of TMOUT was affected by changes make to
+	    it in a subshell.
+	q.  The jobs command did not reflect changes make by
+	    sending the CONT signal to a command.
+	r.  The error message for ksh -o unknown was incorrect.
+	s.  Functions invoked as name=value name, did not use
+	    values from the calling scope when evaluating value.
+	t.  A bug in which the shell would reexecute previously
+	    executed code when a shell script or coprocess was
+	    run in the background has been fixed.
+	u.  A bug in which an empty here-document would leave
+	    a file descriptor open has been fixed.
+	v.  A bug in which $(set -A array ...) would leave a
+	    side effect has been fixed.
+	w.  A discipline function for a global variable defined
+	    within a function defined with the function keyword,
+	    incorrectly created a local variable of the same name
+	    and applied the discipline to it.
+
+12.	Bugs fixed in 12/28/93f for default OPTIONS
+	a.  A bug which would cause the secondary prompt to be
+	    displayed when a user entered a literal carriage
+	    return has been fixed.
+	b.  I bug which caused ksh read -s name to core dump was
+	    fixed.
+	c.  I bug with the expansion of \} and \] inside double
+	    quoted strings that also contained variable expansions
+	    has been fixed
+	d.  Changes in the 'e' point release caused autoload
+	    functions invoked from within command substitution
+	    to fail.  This has been fixed.
+	e.  A bug in the processing of here-documents that could
+	    prevent variable substitution to occur after $(...) command
+	    substitution for long here documents has been fixed.
+	f.  A bug caused by a race condition that could cause SIGTERM
+	    to be ignored by a child process has been fixed.
+	g.  A bug which prevented the startup of a coprocess immediately
+	    after killing a running coprocess has been fixed.
+	h.  ulimit foobar, where foobar is not an arithmetic
+	    expression, now gives an error message as it did with ksh88
+	    instead of setting the file size limit to 0.
+	i.  A bug which could cause an interactive shell to terminate when
+	    the last process of a pipeline was a POSIX function was fixed.
+	j.  A bug which could cause command substitution of a shell script
+	    to core dump has been fixed.
+	k.  A security hole was fixed in suid_exec.
+	l.  Arithmetic functions such as pow() that take more than
+	    one argument, did not work if arguments other than the
+	    first contained parenthesized sub-expression.
+	m.  The error message from a script containing an incomplete
+	    arithmetic expression has been corrected.
+	n.  A bug which caused a core dump on some machines when
+	    the value of a name reference contained a positional
+	    parameter and the name reference was not defined inside
+	    a function has been fixed.
+	o.  Arithmetic expressions now correctly handle hexidecimal
+	    constants.
+	p.  A bug in which integer variables could be expanded
+	    with a leading 10# when declared with typeset -i
+	    multiple times has been corrected.
+	q.  A bug in which IFS wasn't correctly restored when
+	    set within command substitution has been fixed.
+	r.  The _ character is now considered as part of a word
+	    with the M-f and M-b emacs directives as it was in ksh88.
+
+13.	Bugs fixed in 12/28/93g for default OPTIONS
+	a.  A bug in which a name reference could be created to
+	    itself and later cause the shell to get into an infinite
+	    loop has been fixed.
+	b.  A bug in shcomp relating to compound variables was fixed.
+	c.  A bug introduced in 'e' in which leading 0's in -Z
+	    fields caused the value to be treated as octal for arithmetic
+	    evaluation has been fixed.
+	d.  A bug when a name reference with a shorter name than
+            the variable it references was the subject of a compound
+	    assignment has been fixed. 
+	e.  A bug which in which assignment to array variables in
+	    a subshell could effect the parent shell has been
+	    fixed.
+	f.  read name?prompt was putting a 0 byte at the end of the
+	    prompt on standard error.
+	g.  A bug in [[ string1 > string2 ]] when ksh was run with -x
+	    has been fixed.
+	k.  A bug in which the escape character was not processed
+	    correctly inside {...} when brace expansion is enabled
+	    has been fixed, for example {\$foo}.
+	l.  A bug in line continuation in here-documents has been
+	    fixed.
+	m.  The default base when not specified with typeset -i is
+	    10 in accordance with the documentation.  Previously,
+	    the value was determined by the first assignment.   
+	n.  A parsing bug in which a # preceded alphanumeric
+	    characters inside a command substitution caused
+	    a syntax error to be reported has been fixed.
+	o.  A bug in which a decimal constant represented as 10#ddd
+	    where ddd was more than five digits generated a syntax
+	    error has been fixed.
+	p.  A bug in here document expansion in which ${...} expansions
+	    were split across buffer boundaries has been fixed.
+
+14.	Bugs fixed in 12/28/93h for default OPTIONS
+	a.  I bug in shcomp for compilation of unary operators with [[...]]
+	    has been fixed.
+	b.  A bug in which the value of $? was changed when executing
+	    a keyboard trap has been fixed. 
+	c.  The handling of SIGCHLD has been changed so that the
+	    trap is not triggered while executing trap commands
+	    to avoid recursive trap calls.
+	d.  I bug in which a local variable in a function declared readonly
+	    would generated an error when the function went out of
+	    scope has been fixed.
+	e.  I bug in which \<new_line> entered from the keyboard
+	    with the KEYBD trap enabled has been fixed.
+	f.  The error message for a misplaced ((, for example print ((3),
+	    was often garbled and has been fixed.
+	g.  I bug in the KEYBD trap in which escape sequences of the form
+	    <ESC>[#~ were not being handled as a unit has been fixed.
+	h.  A bug in which ksh would consider expressions like [[ (a) ]]
+	    as syntax errors has been fixed.
+	i.  A function defined as foo() without a function body
+	    was not reported as a syntax error.
+	j.  A bug in which ksh could run out of file descriptors when
+	    a stream was repeatedly opened with exec and read from
+	    has been fixed.
+	k.  A bug introduced when fixing item n from the 'g' point
+	    release has been fixed.
+
+15.	Bugs fixed in 12/28/93i for default OPTIONS
+        a.  A bug in which a script could terminate when getopts
+            encountered an error when invoked inside a function
+            has been fixed.
+        b.  When a symbolic link was specified as the name of
+            the script to invoke by name, the value of $0 was
+            set to the real file name rather than the link name
+            in some cases and this has been fixed.
+
+16.	Bug fixes for specific non-default option combinations.
+	a.  More signal names have been added for Solaris
+	b.  A bug fixed for the v directive in vi MULTIBYTE has been
+	    fixed.
+	c.  Code to for IFS handling of multibyte characters has
+	    been added.
+	d.  The displaying of multibyte strings in export, readonly,
+	    typeset, and execution traces has been fixed.
+	e.  A bug with type ahead and KEYBOARD traps with the
+	    MULTIBYTE option set has been fixed.
+	f.  The k-shell information abstraction database option, KIA,
+	    has been revamped for the 'e' point release.
+	g.  A bug in brace pattern expansions that caused expressions
+	    such as {foo\,bar,bam} to expand incorrectly have been fixed.
+	h.  On the U/WIN version for Window 95 and Windows NT,
+	    when a directory beginning with a letter followed by
+	    a colon is given to cd, it is assumed to be an absolute
+	    directory.
+	i.  There was a bug in the compile option that does not
+	    use fork() in which the current option settings where
+	    not propagated to sub-shells.
+	j.  A bug in setting .sh.editchar during the KEYBD trap
+	    for the MULTIBYTE option was fixed in release 'h'.
+	k.  A bug in which the precision given as an argument
+	    to printf was not working has been fixed.
+
+17.	Other changes to 12/28/93[abcdefghi]
+	a.  A couple of minor changes to make adding built-ins easier.
+	b.  Variables inside functions are now statically scoped.
+	    The previous behavior was never documented.
+	c.  A few changes have been made to the name-value library
+	    that affect built-ins that use disciplines.  The
+	    changes allow disciplines to be shared by variables
+	    and should make it possible to add new disciplines
+	    without recompilation.
+	d.  The name-value library interface has undergone significant
+	    change for this revision.  See the new nval.3 man page.
+	e.  Builtin functions can take a third argument which is
+	    a void*.
+	f.  The nv_scan() function can restrict the scope of a walk
+	    to the top scope.  Starting in 'f', nv_scan() has an
+	    additional pointer argument that is passed to each invoked
+	    function.
+	g.  Starting with release 'f', an empty for list behave like
+	    a for list with null expansions.  It produces a warning
+	    message with sh -n.
+	h.  Starting with release 'f' the code has been modified to
+	    work with EBCDIC as well as ASCII.
+	i.  Starting with the release 'g', the name-value pair library
+	    uses the cdt library rather than the hash library.
+	j.  The sh_fun() function now takes third argument which
+	    is an argument list for the invoked discipline function
+	    or built-in.
+	k.  A callback function can be installed which will give
+	    notification of file duplications and file closes.
+	    
+18.	Incompatibilities with 12/28/93 version.
+	None intentional.

+One of the features of \f5ksh93\fP, the latest version of \f5ksh\fP,
+is the ability to add built-in commands at run time.
+This feature only works on operating systems that have the ability
+to load and link code into the current process at run time.
+Some examples of the systems that have this feature
+are System V Release 4, Solaris, Sun OS, HP-UX Release 8 and above,
+AIX 3.2 and above, and Microsoft Windows systems. 
+.P
+This memo describes how to write and compile programs
+to can be loaded into \f5ksh\fP at run  time as built-in
+commands.
+.AE   \" abstract end
+.OK Shell "Command interpreter" Language UNIX  \" keyword
+.MT 1  \"  memo type
+.H 1 INTRODUCTION
+A built-in command is executed without creating a separate process.
+Instead, the command is invoked as a C function by \f5ksh\fP. 
+If this function has no side effects in the shell process,
+then the behavior of this built-in is identical to that of
+the equivalent stand-alone command.  The primary difference
+in this case is performance.  The overhead of process creation
+is eliminated.  For commands of short duration, the effect
+can be dramatic.  For example, on SUN OS 4.1, the time do
+run \f5wc\fP on a small file of about 1000 bytes, runs
+about 50 times faster as a built-in command.
+.P
+In addition, built-in commands that have side effects on the
+shell environment can be written.
+This is usually done to extend the application domain for
+shell programming.  For example, an X-windows extension
+that makes heavy use of the shell variable namespace
+was added as a group of built-ins commands that
+are added at run time.
+The result is a windowing shell that can be used to write
+X-windows applications.
+.P
+While there are definite advantages to adding built-in
+commands, there are some disadvantages as well.
+Since the built-in command and \f5ksh\fP share the same
+address space, a coding error in the built-in program
+may affect the behavior of \f5ksh\fP; perhaps causing
+it to core dump or hang.
+Debugging is also more complex since your code is now
+a part of a larger entity.
+The isolation provided by a separate process
+guarantees that all resources used by the command
+will be freed when the command completes.
+Also, since the address space of \f5ksh\fP will be larger,
+this may increase the time it takes \f5ksh\fP to fork() and
+exec() a non-builtin command.
+It makes no sense to add a built-in command that takes
+a long time to run or that is run only once, since the performance
+benefits will be negligible.
+Built-ins that have side effects in the current shell
+environment have the disadvantage of increasing the
+coupling between the built-in and \f5ksh\fP making
+the overall system less modular and more monolithic.
+.P
+Despite these drawbacks, in many cases extending
+\f5ksh\fP by adding built-in
+commands makes sense and allows reuse of the shell
+scripting ability in an application specific domain.
+This memo describes how to write \f5ksh\fP extensions. 
+.H 1 "WRITING BUILT-IN COMMANDS"
+There is a development kit available for writing \f5ksh\fP
+built-ins.  The development kit has three directories,
+\f5include\fP, \f5lib\fP, and \f5bin\fP.
+The \f5include\fP directory contains a sub-directory
+named \f5ast\fP that contains interface prototypes
+for functions that you can call from built-ins.  The \f5lib\fP
+directory contains the \fBast\fP library\*F
+.FS
+\fBast\fP stands for Advanced Software Technology
+.FE
+and a library named \fBlibcmd\fP that contains a version
+of several of the standard POSIX\*(Rf
+.RS
+.I "POSIX \- Part 2: Shell and Utilities,"
+IEEE Std 1003.2-1992, ISO/IEC 9945-2:1993.
+.RF
+utilities that can be made run time built-ins.
+It is best to set the value of the environment variable
+\fB\s-1PACKAGE_\s+1ast\fP to the pathname of the directory
+containing the development kit.
+Users of \f5nmake\fP\*(Rf
+.RS
+Glenn Fowler,
+Nmake reference needed
+.RF
+2.3 and above will then be able to
+use the rule
+.nf
+.in .5i
+\f5:PACKAGE:	ast\fP
+.in
+.fi
+in their makefiles and not have to specify any \f5-I\fP switches
+to the compiler.
+.P
+A built-in command has a calling convention similar to
+the \f5main\fP function of a program,
+.nf
+.in .5i
+\f5int main(int argc, char *argv[])\fP.
+.in
+.fi
+However, instead of \f5main\fP, you must use the function name
+\f5b_\fP\fIname\fP, where \fIname\fP is the name
+of the built-in you wish to define.
+The built-in function takes a third
+\f5void*\fP  argument which you can define as \f5NULL\fP. 
+Instead of \f5exit\fP, you need to use \f5return\fP
+to terminate your command.
+The return value, will become the exit status of the command.
+.P
+The steps necessary to create and add a run time built-in are
+illustrated in the following simple example.
+Suppose, you wish to add a built-in command named \f5hello\fP
+which requires one argument and prints the word hello followed
+by its argument.  First, write the following program in the file
+\f5hello.c\fP:
+.nf
+.in .5i
+\f5#include     <stdio.h>
+int b_hello(int argc, char *argv[], void *context)
+{
+        if(argc != 2)
+        {
+                fprintf(stderr,"Usage: hello arg\en");
+                return(2);
+        }
+        printf("hello %s\en",argv[1]);
+        return(0);
+}\fP
+.in
+.fi
+.P
+Next, the program needs to be compiled.
+On some systems it is necessary to specify a compiler
+option to produce position independent code
+for dynamic linking.
+If you do not compile with \f5nmake\fP
+it is important to specify the a special include directory
+when compiling built-ins. 
+.nf
+.in .5i
+\f5cc -pic -I$PACKAGE_ast/include -c hello.c\fP
+.in
+.fi
+since the special version of \f5<stdio.h>\fP
+in the development kit is required.
+This command generates \f5hello.o\fP in the current
+directory.
+.P
+On some systems, you cannot load \f5hello.o\fP directly,
+you must build a shared library instead.
+Unfortunately, the method for generating a shared library
+differs with operating system.
+However, if you are building with the AT\&T \f5nmake\fP
+program you can use the \f5:LIBRARY:\fP rule to specify
+this in a system independent fashion. 
+In addition, if you have several built-ins, it is desirable
+to build a shared library that contains them all.
+.P
+The final step is using the built-in.
+This can be done with the \f5ksh\fP command \f5builtin\fP.
+To load the shared library \f5hello.so\fP and to add
+the built-in \f5hello\fP, invoke the command,
+.nf
+.in .5i
+\f5builtin -f hello hello\fP
+.in
+.fi
+The suffix for the shared library can be omitted in
+which case the shell will add an appropriate suffix
+for the system that it is loading from.
+Once this command has been invoked, you can invoke \f5hello\fP
+as you do any other command. 
+.P
+It is often desirable to make a command \fIbuilt-in\fP
+the first time that it is referenced.  The first
+time \f5hello\fP is invoked, \f5ksh\fP should load and execute it,
+whereas for subsequent invocations \f5ksh\fP should just execute the built-in.
+This can be done by creating a file named \f5hello\fP
+with the following contents:
+.nf
+.in .5i
+\f5function hello
+{
+        unset -f hello
+        builtin -f hello hello
+        hello "$@"
+}\fP
+.in
+.fi
+This file \f5hello\fP needs to be placed in a directory that is
+in your \fB\s-1FPATH\s+1\fP variable.  In addition, the full
+pathname for \f5hello.so\fP should be used in this script
+so that the run time loader will be able to find this shared library
+no matter where the command \f5hello\fP is invoked.
+.H 1 "CODING REQUIREMENTS AND CONVENTIONS"
+As mentioned above, the entry point for built-ins must be of
+the form \f5b_\fP\fIname\fP.
+Your built-ins can call functions from the standard C library,
+the \fBast\fP library, interface functions provided by \f5ksh\fP,
+and your own functions.
+You should avoid using any global symbols beginning with
+.BR sh_ ,
+.BR nv_ ,
+and
+.B ed_ 
+since these are used by \f5ksh\fP itself.
+In addition, \f5#define\fP constants in \f5ksh\fP interface
+files, use symbols beginning with \fBSH_\fP to that you should
+avoid using names beginning with \fBSH_\fP.
+.H 2 "Header Files"
+The development kit provides a portable interface
+to the C library and to libast.
+The header files in the development kit are compatible with
+K&R C\*(Rf,
+.RS
+Brian W. Kernighan and Dennis M. Ritchie,
+.IR "The C Programming Language" ,
+Prentice Hall, 1978.
+.RF
+ANSI-C\*(Rf,
+.RS
+American National Standard for Information Systems \- Programming
+Language \- C, ANSI X3.159-1989.
+.RF
+and C++\*(Rf.
+.RS
+Bjarne Stroustroup,
+.IR "C++" ,
+Addison Wesley, xxxx
+.RF
+.P
+The best thing to do is to include the header file \f5<shell.h>\fP.
+This header file causes the \f5<ast.h>\fP header, the
+\f5<error.h>\fP header and the \f5<stak.h>\fP
+header to be included as well as defining prototypes
+for functions that you can call to get shell
+services for your builtins.
+The header file \f5<ast.h>\fP
+provides prototypes for many \fBlibast\fP functions
+and all the symbol and function definitions from the
+ANSI-C headers, \f5<stddef.h>\fP,
+\f5<stdlib.h>\fP, \f5<stdarg.h>\fP, \f5<limits.h>\fP,
+and \f5<string.h>\fP.
+It also provides all the symbols and definitions for the
+POSIX\*(Rf
+.RS
+.I "POSIX \- Part 1: System Application Program Interface,"
+IEEE Std 1003.1-1990, ISO/IEC 9945-1:1990.
+.RF
+headers \f5<sys/types.h>\fP, \f5<fcntl.h>\fP, and
+\f5<unistd.h>\fP.
+You should include \f5<ast.h>\fP instead of one or more of
+these headers.
+The \f5<error.h>\fP header provides the interface to the error
+and option parsing routines defined below.
+The \f5<stak.h>\fP header provides the interface to the memory
+allocation routines described below.
+.P
+Programs that want to use the information in \f5<sys/stat.h>\fP
+should include the file \f5<ls.h>\fP instead.
+This provides the complete POSIX interface to \f5stat()\fP
+related functions even on non-POSIX systems.
+.P
+.H 2 "Input/Output"
+\f5ksh\fP uses \fBsfio\fP,
+the Safe/Fast I/O library\*(Rf,
+.RS
+David Korn and Kiem-Phong Vo,
+.IR "SFIO - A Safe/Fast Input/Output library,"
+Proceedings of the Summer Usenix,
+pp. , 1991.
+.RF
+to perform all I/O operations.
+The \fBsfio\fP library, which is part of \fBlibast\fP,
+provides a superset of the functionality provided by the standard
+I/O library defined in ANSI-C.
+If none of the additional functionality is required,
+and if you are not familiar with \fBsfio\fP and
+you do not want to spend the time learning it,
+then you can use \fBsfio\fP via the \fBstdio\fP library
+interface.  The development kit contains the header \f5<stdio.h>\fP
+which maps \fBstdio\fP calls to \fBsfio\fP calls.
+In most instances the mapping is done
+by macros or inline functions so that there is no overhead.
+The man page for the \fBsfio\fP library is in an Appendix.
+.P
+However, there are some very nice extensions and
+performance improvements in \fBsfio\fP
+and if you plan any major extensions I recommend
+that you use it natively.
+.H 2 "Error Handling"
+For error messages it is best to use the \fBast\fP library
+function \f5errormsg()\fP rather that sending output to
+\f5stderr\fP or the equivalent \f5sfstderr\fP directly.
+Using \f5errormsg()\fP will make error message appear
+more uniform to the user.
+Furthermore, using \f5errormsg()\fP should make it easier
+to do error message translation for other locales
+in future versions of \f5ksh\fP.
+.P
+The first argument to
+\f5errormsg()\fP specifies the dictionary in which the string
+will be searched for translation.
+The second argument to \f5errormsg()\fP contains that error type
+and value.  The third argument is a \fIprintf\fP style format
+and the remaining arguments are arguments to be printed
+as part of the message.  A new-line is inserted at the
+end of each message and therefore, should not appear as
+part of the format string.
+The second argument should be one of the following:
+.VL .5i
+.LI \f5ERROR_exit(\fP\fIn\fP\f5)\fP:
+If \fIn\fP is not-zero, the builtin will exit value \fIn\fP after
+printing the message.
+.LI \f5ERROR_system(\fP\fIn\fP\f5)\fP:
+Exit builtin with exit value \fIn\fP after printing the message.
+The message will display the message corresponding to \f5errno\fP
+enclosed within \f5[\ ]\fP at the end of the message.
+.LI \f5ERROR_usage(\fP\fIn\fP\f5)\fP:
+Will generate a usage message and exit.  If \fIn\fP is non-zero,
+the exit value will be 2.  Otherwise the exit value will be 0.
+.LI \f5ERROR_debug(\fP\fIn\fP\f5)\fP:
+Will print a level \fIn\fP debugging message and will then continue.
+.LI \f5ERROR_warn(\fP\fIn\fP\f5)\fP:
+Prints a warning message. \fIn\fP is ignored.
+.H 2 "Option Parsing"
+The first thing that a built-in should do is to check
+the arguments for correctness and to print any usage
+messages on standard error.
+For consistency with the rest of \f5ksh\fP, it is best
+to use the \f5libast\fP functions \f5optget()\fP and
+\f5optusage()\fPfor this
+purpose.
+The header \f5<error.h>\fP included prototypes for
+these functions.
+The \f5optget()\fP function is similar to the
+System V C library function \f5getopt()\fP,
+but provides some additional capabilities.
+Built-ins that use \f5optget()\fP provide a more
+consistent user interface.
+.P
+The \f5optget()\fP function is invoked as
+.nf
+.in .5i
+\f5int optget(char *argv[], const char *optstring)\fP
+.in
+.fi
+where \f5argv\fP is the argument list and \f5optstring\fP
+is a string that specifies the allowable arguments and
+additional information that is used to format \fIusage\fP
+messages.
+In fact a complete man page in \f5troff\fP or \f5html\fP
+can be generated by passing a usage string as described
+by the \f5getopts\fP command.
+Like \f5getopt()\fP,
+single letter options are represented by the letter itself,
+and options that take a string argument are followed by the \f5:\fP
+character.
+Option strings have the following special characters:
+.VL .5i
+.LI \f5:\fP
+Used after a letter option to indicate that the option
+takes an option argument.
+The variable \f5opt_info.arg\fP will point to this
+value after the given argument is encountered.
+.LI \f5#\fP
+Used after a letter option to indicate that the option
+can only take a numerical value.
+The variable \f5opt_info.num\fP will contain this
+value after the given argument is encountered.
+.LI \f5?\fP
+Used after a \f5:\fP or \f5#\fP (and after the optional \f5?\fP)
+to indicate the the
+preceding option argument is not required.
+.LI \f5[\fP...\f5]\fP
+After a \f5:\fP or \f5#\fP, the characters contained
+inside the brackets are used to identify the option
+argument when generating a \fIusage\fP message. 
+.LI \fIspace\fP
+The remainder of the string will only be used when generating
+usage messages.
+.LE
+.P
+The \f5optget()\fP function returns the matching option letter if
+one of the legal option is matched.
+Otherwise, \f5optget()\fP returns
+.VL .5i
+.LI \f5':'\fP
+If there is an error.  In this case the variable \f5opt_info.arg\fP
+contains the error string.
+.LI \f50\fP
+Indicates the end of options.
+The variable \f5opt_info.index\fP contains the number of arguments
+processed.
+.LI \f5'?'\fP
+A usage message has been required.
+You normally call \f5optusage()\fP to generate and display
+the usage message.
+.LE
+.P
+The following is an example of the option parsing portion
+of the \f5wc\fP utility.
+.nf
+.in +5
+\f5#include <shell.h>
+while(1) switch(n=optget(argv,"xf:[file]"))
+{
+	case 'f':
+		file = opt_info.arg;
+		break;
+	case ':':
+		error(ERROR_exit(0), opt_info.arg);
+		break;
+	case '?':
+		error(ERROR_usage(2), opt_info.arg);
+		break;
+}\fP
+.in
+.fi
+.H 2 "Storage Management"
+It is important that any memory used by your built-in
+be returned.  Otherwise, if your built-in is called frequently,
+\f5ksh\fP will eventually run out of memory.
+You should avoid using \f5malloc()\fP for memory that must
+be freed before returning from you built-in, because by default,
+\f5ksh\fP will terminate you built-in in the event of an
+interrupt and the memory will not be freed.
+.P
+The best way to to allocate variable sized storage is
+through calls to the \fBstak\fP library
+which is included in \fBlibast\fP
+and which is used extensively by \f5ksh\fP itself.
+Objects allocated with the \f5stakalloc()\fP
+function are freed when you function completes
+or aborts. 
+The \fBstak\fP library provides a convenient way to
+build variable length strings and other objects dynamically.
+The man page for the \fBstak\fP library is contained
+in the Appendix.
+.P
+Before \f5ksh\fP calls each built-in command, it saves
+the current stack location and restores it after
+it returns.
+It is not necessary to save and restore the stack
+location in the \f5b_\fP entry function, 
+but you may want to write functions that use this stack
+are restore it when leaving the function.
+The following coding convention will do this in
+an efficient manner:
+.nf
+.in .5i
+\fIyourfunction\fP\f5()
+{
+        char	*savebase;
+        int	saveoffset;
+        if(saveoffset=staktell())
+        	savebase = stakfreeze(0);
+        \fP...\f5
+        if(saveoffset)
+        	stakset(savebase,saveoffset);
+        else
+        	stakseek(0);
+}\fP
+.in
+.fi
+.H 1 "CALLING \f5ksh\fP SERVICES"
+Some of the more interesting applications are those that extend
+the functionality of \f5ksh\fP in application specific directions.
+A prime example of this is the X-windows extension which adds
+builtins to create and delete widgets.
+The \fBnval\fP library is used to interface with the shell
+name space.
+The \fBshell\fP library is used to access other shell services.
+.H 2 "The nval library"
+A great deal of power is derived from the ability to use
+portions of the hierarchal variable namespace provided by \f5ksh-93\fP
+and turn these names into active objects.
+.P
+The \fBnval\fP library is used to interface with shell
+variables.
+A man page for this file is provided in an Appendix.
+You need to include the header \f5<nval.h>\fP
+to access the functions defined in the \fBnval\fP library.
+All the functions provided by the \fBnval\fP library begin
+with the prefix \f5nv_\fP.
+Each shell variable is an object in an associative table
+that is referenced by name.
+The type \f5Namval_t*\fP is pointer to a shell variable. 
+To operate on a shell variable, you first get a handle
+to the variable with the \f5nv_open()\fP function
+and then supply the handle returned as the first
+argument of the function that provides an operation
+on the variable.
+You must call \f5nv_close()\fP when you are finished
+using this handle so that the space can be freed once
+the value is unset.
+The two most frequent operations are to get the value of
+the variable, and to assign value to the variable.
+The \f5nv_getval()\fP returns a pointer the the
+value of the variable.
+In some cases the pointer returned is to a region that
+will be overwritten by the next \f5nv_getval()\fP call
+so that if the value isn't used immediately, it should
+be copied.
+Many variables can also generate a numeric value.
+The \f5nv_getnum()\fP function returns a numeric
+value for the given variable pointer, calling the
+arithmetic evaluator if necessary.
+.P
+The \f5nv_putval()\fP function is used to assign a new
+value to a given variable.
+The second argument to \f5putval()\fP is the value
+to be assigned
+and the third argument is a \fIflag\fP which
+is used in interpreting the second argument.
+.P
+Each shell variable can have one or more attributes.
+The \f5nv_isattr()\fP is used to test for the existence
+of one or more attributes.
+See the appendix for a complete list of attributes.
+.P
+By default, each shell variable passively stores the string you
+give with with \f5nv_putval()\fP, and returns the value
+with \f5getval()\fP.  However, it is possible to turn
+any node into an active entity by assigning functions
+to it that will be called whenever \f5nv_putval()\fP
+and/or \f5nv_getval()\fP is called.
+In fact there are up to five functions that can 
+associated with each variable to override the
+default actions.
+The type \f5Namfun_t\fP is used to define these functions.
+Only those that are non-\f5NULL\fP override the
+default actions.
+To override the default actions, you must allocate an
+instance of \f5Namfun_t\fP, and then assign
+the functions that you wish to override.
+The \f5putval()\fP
+function is called by the \f5nv_putval()\fP function.
+A \f5NULL\fP for the \fIvalue\fP argument
+indicates a request to unset the variable.
+The \fItype\fP argument might contain the \f5NV_INTEGER\fP
+bit so you should be prepared to do a conversion if
+necessary.
+The \f5getval()\fP
+function is called by \f5nv_getval()\fP
+value and must return a string.
+The \f5getnum()\fP
+function is called by by the arithmetic evaluator
+and must return double.
+If omitted, then it will call \f5nv_getval()\fP and
+convert the result to a number.
+.P
+The functionality of a variable can further be increased
+by adding discipline functions that
+can be associated with the variable.
+A discipline function allows a script that uses your
+variable to define functions whose name is
+\fIvarname\fP\f5.\fP\fIdiscname\fP
+where \fIvarname\fP is the name of the variable, and \fIdiscname\fP
+is the name of the discipline.
+When the user defines such a function, the \f5settrap()\fP
+function will be called with the name of the discipline and
+a pointer to the parse tree corresponding to the discipline
+function.
+The application determines when these functions are actually
+executed.
+By default, \f5ksh\fP defines \f5get\fP,
+\f5set\fP, and \f5unset\fP as discipline functions.
+.P
+In addition, it is possible to provide a data area that
+will be passed as an argument to
+each of these functions whenever any of these functions are called.
+To have private data, you need to define and allocate a structure
+that looks like
+.nf
+.in .5i
+\f5struct \fIyours\fP
+{
+        Namfun_t	fun;
+	\fIyour_data_fields\fP;
+};\fP
+.in
+.fi
+.H 2 "The shell library"
+There are several functions that are used by \f5ksh\fP itself
+that can also be called from built-in commands.
+The man page for these routines are in the Appendix.
+.P
+The \f5sh_addbuiltin()\fP function can be used to add or delete
+builtin commands.  It takes the name of the built-in, the
+address of the function that implements the built-in, and
+a \f5void*\fP pointer that will be passed to this function
+as the third agument whenever it is invoked.
+If the function address is \f5NULL\fP, the specified built-in
+will be deleted.  However, special built-in functions cannot
+be deleted or modified.
+.P
+The \f5sh_fmtq()\fP function takes a string and returns
+a string that is quoted as necessary so that it can
+be used as shell input.
+This function is used to implement the \f5%q\fP option
+of the shell built-in \f5printf\fP command.
+.P
+The \f5sh_parse()\fP function returns a parse tree corresponding
+to a give file stream.  The tree can be executed by supplying
+it as the first argument to
+the \f5sh_trap()\fP function and giving a value of \f51\fP as the
+second argument. 
+Alternatively, the \f5sh_trap()\fP function can parse and execute
+a string by passing the string as the first argument and giving \f50\fP
+as the second argument.
+.P
+The \f5sh_isoption()\fP function can be used to set to see whether one
+or more of the option settings is enabled.

+[+NAME?gnaw - maze game written in ksh93]
+[+DESCRIPTION?\bgnaw\b is a maze game.
+        The player maneuvers a yellow '@' sign to navigate a maze while eating
+        small dots. A level is finished when all the dots are eaten. Five monsters
+        (maw, claw, jitterbug, tentacle and grendel) also wander the maze in an attempt
+        to catch the '@'. Each level begins with all ghosts in their home, and '@' near
+        the bottom of the maze. The monsters are released from the home one by one at the
+        start of each level and start their rentless hunt after the player.]
+[q:quiet?Disable use of terminal bell.]

+.SH DESCRIPTION
+.PP
+\fINval\fP is a library of functions for interacting with name-value
+pairs as used in \f5ksh\fP.
+It is built on top the container dictionary type library facility
+in \f5libcdt\fP. (See cdt(3)).
+Each name-value pair is represented by a
+type named \f5Namval_t\fP. 
+A \f5Namval_t\fP contains the name, value and
+attributes of a variable.
+Some attributes can have an associated number that
+represents the field width, arithmetic base, or precision.
+Additionally, each name-value pair can be associated with
+one or more processing disciplines that affect
+its behavior.
+.PP
+The function \f5nv_open()\fP returns a pointer to a name-value
+pair corresponding to the given \fIname\fP.
+It can also assign a value and give attributes to a name-value pair.
+The argument \fIdict\fP defines the dictionary to search.
+A \f5NULL\fP value causes the shell global variable dictionary to be searched.
+.PP
+The \fIflags\fP argument consists of the bitwise-or of zero or more
+of the attributes listed later and zero or more of the following:
+.IP
+\f5NV_VARNAME\fP:
+An invalid variable name causes an error.
+.IP
+\f5NV_IDENTIFIER\fP:
+A variable name that is not an identifier causes an error.
+.IP
+\f5NV_ASSIGN\fP:
+The \fIname\fP argument can contain an assignment.
+.IP
+\f5NV_NOARRAY\fP:
+The \fIname\fP argument cannot contain a subscript.
+.IP
+\f5NV_NOREF\fP:
+Do not follow references when finding the name-value pair.
+.IP
+\f5NV_NOADD\fP:
+The name-value pair will not be added if it doesn't exist.
+Instead, a \f5NULL\fP pointer will be returned.
+.IP
+\f5NV_NOSCOPE\fP:
+Only the top level scope is used.
+.IP
+\f5NV_NOFAIL\fP:
+Just return \f5NULL\fP when an error occurs.
+By default an error message is displayed and the current command
+is aborted.
+.IP
+.PP
+If a name-value pair by this name does not already exist, it is
+created unless \fIflags\fP contains the \f5NV_NOADD\fP flag.
+If \f5NV_VARNAME\fP, \f5NV_IDENTIFIER\fP and \f5NV_ASSIGN\fP are
+all not specified, then no validity check is performed on the \fIname\fP
+argument and no further processing is performed.
+Otherwise, if \f5NV_ASSIGN\fP is specified, then the characters up
+to the first \f5=\fP or \f5+=\fP are used to find the name-value pair,
+and the characters after the \f5=\fP are used to define
+the value that will be assigned to this name-value pair.
+If \fIname\fP does not contain an \f5=\fP, than no assignment
+will be made.
+If the first identifier in \fIname\fP is a reference and is not
+preceded by a \fB.\fP,
+it will be replaced by the value of the reference
+to find the name of a variable.
+Unless \fIflags\fP contains the \f5NV_NOREF\fP flag,
+if the name-value pair give by \fIname\fP has the \f5NV_REF\fP
+attribute, it will be replaced by the variable whose name
+is the value of this name-value pair.
+If \f5NV_ASSIGN\fP is set in the \fIflags\fP argument,
+the \fIname\fP variable can contain an \f5=\fP
+and a value that will be assigned to the name-value pair.
+Any attributes appearing in the \fIflags\fP argument
+will be applied to the name-value pair after any value is assigned.
+.PP
+It is possible for an application to create additional dictionaries
+with the cdt library and associate them with name-value pairs.
+The \f5nv_dict()\fP function returns the dictionary associated with
+the specified name-value pair, or if no dictionary was specified,
+\f5NULL\fP is returned.
+The \f5nv_lastdict()\fP function returns a pointer the the
+name-value pair that contains
+the last dictionary searched on the previous \f5nv_open()\fP.
+.PP
+The \f5nv_close()\fP indicates that the pointer returned by
+\f5nv_open()\fP or \f5nv_opensub()\fP will not be referenced again.  If the
+name-value pair is unset, and not referenced elsewhere,
+the name-value pair may be freed.
+.PP
+The \f5nv_name()\fP function returns the name of the given name-value
+pair \fInp\fP.
+The \f5nv_setsize()\fP function returns the size of the field for
+justified variables, the arithmetic base for integer variables,
+and the precision or number of places after the decimal point
+for floating point variables.  If \fIsize\fP is greater than or
+equal to zero, the current size is changed to this value. 
+The \f5nv_size()\fP function is equivalent to \f5nv_setsize()\fP
+with the second argument negative.
+.PP
+The \f5nv_getval()\fP function returns the value of the given
+name-value pair as a string.  A \f5NULL\fP return value indicates
+that the name-value pair is unset.
+The \f5nv_getnum()\fP function returns the value of the given
+name-value pair as a double precision number using the \f5Sfio\fP
+library  (See Sfio(3)) type \f5Sfdouble_t\fP.
+For name-value pairs without the \f5NV_INTEGER\fP attribute,
+the string value is evaluated as an arithmetic expression to
+arrive at a numerical value.
+.PP
+The \f5nv_putval()\fP function is used to assign a \fIvalue\fP to
+the name-value pair \fInp\fP.
+The \fIflags\fP argument consists zero or more of the bitwise-or
+of \f5NV_LONG\fP, \f5NV_SHORT\fP, \f5NV_DOUBLE\fP, \f5NV_INTEGER\fP,
+\f5NV_RDONLY\fP, \f5NV_REF\fP, \f5NV_BINARY\fP, and \f5NV_NOFREE\fP.
+The presence of \f5NV_RDONLY\fP allows the assignment to occur
+even if the name-value pair has the \f5NV_RDONLY\fP attribute.
+The presence of \f5NV_INTEGER\fP indicates that the \fIvalue\fP
+argument is actually a pointer to a numerical type.
+By default this type is \f5long\fP, but can be modified with
+\f5NV_LONG\fP, \f5NV_SHORT\fP, and \f5NV_DOUBLE\fP
+to represent \f5long long\fP, \f5short\fP, \f5double\fP, \f5long double\fP,
+and \f5float\fP.
+The presence of \f5NV_REF\fP indicates that the \fIvalue\fP
+argument is actually a pointer to a name-value pair
+and \f5np\fP should become a reference to this name-value pair.
+If \f5NV_NOFREE\fP is specified, \fIvalue\fP itself becomes
+the value of the name-value pair \fInp\fP.
+Otherwise, a  copy of the value is stored
+as the value for \fInp\fP.
+.PP
+The \f5nv_unset()\fP function clears out the value and attributes
+of the given name-value function but does not free the name-value
+pair.
+.PP
+The following attributes can be associated with a name-value pair:
+.IP
+\f5NV_EXPORT\fP:
+The export attribute.
+.IP
+\f5NV_RDONLY\fP:
+The readonly attribute.
+.IP
+\f5NV_LTOU\fP:
+Lower case characters are converted to upper case characters.
+.IP
+\f5NV_UTOL\fP:
+Upper case characters are converted to lower case characters.
+.IP
+\f5NV_RJUST\fP:
+Right justify and blank fill.
+This attribute has an associated size that defines the
+string length of the value.
+.IP
+\f5NV_LJUST\fP:
+Left justify and blank fill.
+This attribute has an associated size that defines the
+string length of the value.
+.IP
+\f5NV_ZFILL\fP:
+Without \f5NV_LJUST\fP, right justifies and fills with leading zeros.
+With \f5NV_LJUST\fP, left justify and strip leading zeros.
+Left justify and blank fill.
+This attribute has an associated size that defines the
+string length of the value.
+.IP
+\f5NV_TAGGED\fP:
+Indicates the tagged attribute.
+.IP
+\f5NV_INTEGER\fP:
+Causes value to be represented by a number.
+This attribute has an associated number that defines the
+arithmetic base to be used when the value is expanded as a string.
+.IP
+\f5NV_DOUBLE\fP:
+Used in conjunction with \f5NV_INTEGER\fP to cause value
+to be stored as a double precision floating point number.
+This attribute has an associated number that defines the
+number of places after the decimal point to be used when
+the value is expanded as a string.
+.IP
+\f5NV_EXPNOTE\fP:
+Used in conjunction with \f5NV_INTEGER\fP and \f5NV_DOUBLE\fP to
+cause the value to be represented in scientific notation when
+expanded as a string.
+This attribute has an associated number that defines the
+the precision of the mantissa.
+.IP
+\f5NV_BINARY\fP:
+The name-value pair contains a buffer of binary data and \f5nv_size()\fP
+is the number of bytes for this data.  By default the value
+will be represented by the base64 encoding of the buffer.
+The \f5NV_LJUST\fP flag may also be specified and causes the buffer
+size to be fixed and data either truncated or filled with \f50\fP bytes.
+.IP
+\f5NV_REF\fP:
+The name-value pair is a name reference variable.
+.IP
+\f5NV_NODISC\fP:
+All discipline functions are ignored when performing assignments
+and lookups.
+.PP
+The \f5nv_isattr()\fP function can test whether or not any of
+the attributes given by \fIflags\fP is set.
+The \f5nv_onattr()\fP and \f5nv_offattr()\fP functions turn attributes
+on or off respectively.  Only attributes that do not affect the
+value can be set in this way.
+The \f5nv_newattr()\fP function can be used to change the
+attributes and size of the given name-value pair which may result
+in the value being changed to conform to the new attributes and size.
+The \fIsize\fP argument is needed for attributes that require
+an additional argument such as justifies variables.
+Changing the attribute may require changing the value
+to agree with the new attributes.
+For an array variable, the values for each of the
+subscripts will be changed.
+.PP
+The \f5nv_isarray()\fP function returns a non-zero value if the specified
+name-value pair is an array. 
+.PP
+The \f5nv_scan()\fP function is used to walk through
+all name-value pairs in the dictionary given by \fIdict\fP.
+If the \f5flags\fP variable contains the \f5NV_NOSCOPE\fP
+flag, then only the top scope will be examined.
+The remaining flags will be used in conjunction with \fImask\fP
+to further restrict the walk.
+If \fImask\fP is non-zero, only the nodes for which 
+\f5nv_isattr(\fP\fInode\fP\f5,\fP\fImask\fP\f5)\fP
+is equal to \fIflags\fP will be visited.
+If \fIfn\fP is non-zero, then this function will be executed
+for each name-value pair in the walk. 
+The arguments to \fIfn\fP will be a pointer to the name-value pair
+and the \fIdata\fP pointer passed to \f5nv_scan()\fP.
+The number of elements visited will be returned.
+.PP
+The \f5nv_clone()\fP function is used make a copy of the contents of
+name-value pair \fIsrc\fP to another name-value pair \fIdest\fP.
+.PP
+Disciplines provide a way to
+intercept the lookup and assignment operations,
+to manage the creation of sub-variables,
+and to extend the operations permitted on a name-value pair.
+A discipline consists of a set of one or more functions and related
+data that are used to override and extend the operations
+on a name-value pair. 
+A discipline is defined by the types
+\f5Namfun_t\fP and \f5Namdisc_t\fP.
+The \f5Namdisc_t\fP is not modified by any of these functions and
+can therefore be shared by several name-value pairs. 
+It contains following public fields in the order listed:
+.nf
+      \f5size_t	dsize;\fP
+      \f5void	(*putval)(Namval_t*,const char*,int,Namfun_t*);\fP
+      \f5char	*(*getval)(Namval_t*,Namfun_t*);\fP
+      \f5double	(*getnum)(Namval_t*,Namfun_t*);\fP
+      \f5char	*(*setdisc)(Namval_t*,const char*,Namval_t*,Namfun_t*);\fP
+      \f5Namval_t	*(*createf)(Namval_t*,const char*,Namfun_t*);\fP
+      \f5Namfun_t	*(*clonef)(Namval_t*,Namval_t*,int,Namfun_t*);\fP
+      \f5char	*(*namef)(Namval_t*,Namfun_t*);\fP
+      \f5Namval_t	*(*nextf)(Namval_t*,Dt_t*,Namfun_t*);\fP
+      \f5Namval_t	*(*typef)(Namval_t*,Namfun_t*);\fP
+.fi
+The \f5Namfun_t\fP type contains a member named
+\f5disc\fP which points to a \f5Namdisc_t\fP structure.
+To create a discipline with additional user data,
+define a structure with an instance of \f5Namfun_t\fP
+as the first element.
+An application must initialize the \f5Namfun_t\fP portion of
+the structure to zero and then set the \fIdisc\fP field to point
+to the \f5Namdisc_t\fP structure.
+The \f5dsize\fP field of the \f5Namdisc_t\fP structure must be
+the size of this structure.  A value of 0,
+indicates that there are no additional fields and is equivalent
+to \f5sizeof(Namfun_t)\fP.
+If different instances of this structure uses different sizes, then
+the \f5size\fP field in the \f5Namfun_t\fP can must be set to
+this size and overrides the value in the \f5Namdisc_t\fP structure.
+.PP
+When a variable is referenced by calling the \f5nv_getval()\fP function,
+and the \f5NV_NODISC\fP attribute is not set,
+the \f5getval()\fP discipline function is called with a pointer
+to the name-value pair, \fInp\fP, and a pointer to the discipline,
+\fIfp\fP.
+Inside the \f5getval()\fP function, the \f5nv_getv()\fP function
+can be called to get the value of the name-value pair that
+would have resulted if the discipline were not used.
+The \f5getnum()\fP discipline is called whenever a numerical
+value is needed for the name-value pair \fInp\fP
+and the \f5NV_NODISC\fP attribute is not set,
+The \f5nv_getn()\fP function can be called from within
+the \f5getnum()\fP discipline to get the value that would
+have resulted if there were no \f5getnum()\fP discipline.
+.PP
+The \f5putval\fP\f5()\fP discipline function is used to
+override the assignment of values
+to a name-value pair.
+It is called whenever a value is assigned with \f5nv_putval()\fP
+and the \f5NV_NODISC\fP attribute is not set,
+or when a name-value pair is unset with \f5nv_unset()\fP.
+When a name-value pair is unset, \f5putval\fP\f5()\fP
+is called with \fIvalue\fP set to \f5NULL\fP. 
+The \f5nv_putv()\fP function is used within the \f5putval()\fP
+to perform the assignment or unset that would have occurred
+if the discipline had not been installed.
+.PP
+The \f5createf()\fP discipline function is called from
+\f5nv_open()\fP or \f5nv_create()\fP when the name-value pair preceding a
+.B \s+2.\s-2
+is found.
+This function is passed the name-value pointer plus the remaining string and
+the current \fIflags\fP argument.
+The \f5createf()\fP discipline function
+must return the created name-value pair, otherwise the default action
+will be taken.
+If the name-value pair that is returned  is the same as the
+one given, then the the behavior will be the same as if
+an invalid name had been given to \f5nv_open()\fP.
+The \f5nv_create()\fP function may be called within
+the \f5createf()\fP discipline function
+to perform the action that would have occurred
+by an earlier \f5nv_open()\fP function.
+.PP
+The \f5setdisc()\fP discipline function is used
+to extend the set of available shell level discipline functions
+associated with a name-value pair by allowing
+builtins or functions whose name is of the
+form \fIvarname\fP\f5.\fP\fIaction\fP to be defined.
+By default, each name-value pair can have a \f5get\fP,
+\f5set\fP, and \f5unset\fP discipline associated with it.
+Whenever a builtin or function whose name is of the 
+form \fIvarname\fP\f5.\fP\fIaction\fP is defined or is unset,
+and \fIaction\fP is not \f5get\fP,
+\f5set\fP, or \f5unset\fP, the \fIsetdisc\fP\f5()\fP function is invoked
+with the same argument format as \f5nv_setdisc\fP\f5()\fP.
+The argument \fIf\fP points to the name-value pair associated
+with the function being defined, or \f5NULL\fP if the function is
+being unset.
+If the given action \fIa\fP is not known by this discipline,
+it should return the value returned by calling
+\f5nv_setdisc(\fP\fInp\fP\f5,\fP\fIa\fP\f5,\fP\fIf\fP\f5,\fP\fIfp\fP\f5)\fP
+so that it can be searched for in previously stacked disciplines.
+Otherwise, the \fIsetdisc\fP\f5()\fP function should save the function
+name-value pair pointer, and return a non-\f5NULL\fP value.
+The name-value pointer to the function can be used to invoke
+the function at an application defined point.
+If the action \fIa\fP is \f5NULL\fP, then \fIf\fP points to
+an action name instead of a name-value pair pointer.
+The \fIsetdisc\fP\f5()\fP must return the
+name of the action that follows the action name given by
+\fIf\fP.  If \fIf\fP is also \f5NULL\fP, the name of the first action
+must be returned.
+This allows an application to get the list of valid discipline
+action names allowed by a given name-value pair.
+.PP
+The \f5nv_adddisc()\fP function is a higher level function that
+adds a \fIsetdisc\fP discipline to the name-value pair that allows
+shell level disciplines to be created for each of the name specified
+in \f5names\fP.
+.PP
+The \f5nv_discfun()\fP function can be used to get a pointer to
+discipline functions that are provided by the library.
+Currently, the only one that is provided is the ones used to
+implement \f5nv_adddisc()\fP which can be returned with an
+argument of \f5NV_DCADD\fP.
+.PP
+The \f5clonef()\fP discipline function is called by \f5nv_clone()\fP
+when making a copy of the \f5Namfun_t\fP discipline to the new node.  
+The first argument is the original node, the second argument is
+the new node, and the third argument is the flags that were passed
+down to \f5nv_clone()\fP.
+It must return a new instance of the \f5Namfun_t*\fP \f5fp\fP.
+If omitted, then memory whose size is determinated by the \f5size\fP
+field of \f5fp\fP, if non-zero, or \f5fp->disc\fP, will be allocated
+and copied from \f5fp\fP.
+.PP
+The \f5namef()\fP discipline function returns the name for this name-value pair.
+.PP
+The \f5nextf()\fP is used for walking through the list of sub-variables
+associated with this name-value pair.  If the dictionary argument is
+\f5NULL\fP, it must return the first sub-variable.  Otherwise,
+it must return the next sub-variable, or \f5NULL\fP if there are
+no more variables.
+.PP
+A discipline is installed or removed with the
+\f5nv_disc()\fP function.
+The following flags can be specified:
+.IP
+\f5NV_FIRST\fP:
+If \fIfp\fP is non-\f5NULL\fP, the discipline is moved to the top
+of the stack or pushed onto the top of the stack of disciplines
+associated with the given name-value
+pair \fInp\fP if not already present.
+Otherwise, the top of the discipline stack is returned.
+.IP
+\f5NV_LAST\fP:
+If \fIfp\fP is non-\f5NULL\fP, the discipline is moved to the bottom
+of the stack or pushed onto the bottom of the stack of disciplines
+associated with the given name-value
+pair \fInp\fP if not already present.
+Otherwise, the bottom of the discipline stack is returned.
+.IP
+\f5NV_POP\fP:
+If \fIfp\fP is non-\f5NULL\fP and it is on the stack,
+it is removed and \fIfp\fP is returned.  If  \fIfp\fP is non-\f5NULL\fP
+and is not on the stack, \f5NULL\fP is returned.
+Otherwise, the the top discipline is popped
+and returned.
+.IP
+\f5NV_CLONE\fP:
+If \fIfp\fP is non-\f5NULL\fP and it is on the stack,
+it is replace by a copy created by \f5malloc\fP(3).
+The \f5nofree\fP field is set to \f50\fP.
+The new discipline is returned.
+Otherwise, \f5NULL\fP is returned.
+.IP
+\f50\fP:
+If \fIfp\fP is non-\f5NULL\fP then it is equivalent to \f5NV_FIRST\fP.
+Otherwise, it is equivalent to \f5NV_POP\fP.
+.PP
+The
+\f5nv_hasdisc()\fP function can be used to tell whether a discipline
+whose discipline functions are those defined in \fIdp\fP.
+A pointer to this discipline is returned.
+.PP
+The \f5nv_aindex()\fP function returns
+the current index for
+the indexed array given by the name-value pair pointer \fInp\fP. 
+The return value is negative if \fInp\fP refers to
+an associative array.
+.PP
+The \f5nv_setarray()\fP function is used to create an associative array
+from a name-value pair node.
+The function \fIfun\fP defines the semantics of the associative
+array.
+Using \fIfun\fP equal to \f5nv_associative()\fP implements the default
+associative array semantics
+that are used with \f5typeset\ -A\fP.
+The function \fIfun\fP will be called with third argument as follows:
+.IP
+\f5NV_AINIT\fP:
+This will be called at initialization.
+The function you supply must return a pointer to a structure
+that contains the type \f5Namarr_t\fP as the first element.
+All other calls receive this value as an argument.
+.IP
+\f5NV_AFREE\fP:
+This will be called after all elements of the name-value pair have been
+deleted and the array is to be freed.
+.IP
+\f5NV_ADELETE\fP:
+The current element should be deleted.
+.IP
+\f5NV_ANEXT\fP:
+This means that the array subscript should be advanced to the
+next subscript.  A \f5NULL\fP return indicates that there are
+no more subscripts.
+.IP
+\f5NV_ANAME\fP:
+The name of the current subscript must be returned.
+.IP
+\f5NV_ACURRENT\fP:
+Returns a pointer to a name-value pair corresponding to the
+current subscript, or \f5NULL\fP if this array type doesn't
+create represent each element as a name-value pair.
+.PP
+If \fInp\fP refers to an array,
+the \f5nv_getsub()\fP returns a pointer to
+the name of the current subscript.
+Otherwise, \f5nv_getsub()\fP
+returns \f5NULL\fP.
+.PP
+The \f5nv_opensub()\fP function returns
+a pointer to the name-value pair corresponding
+to the current subscript in an associative array.
+Note that the \f5nv_close()\fP function should be called
+when the pointer is no longer needed.
+.PP
+The \f5nv_putsub()\fP function is used to
+set the subscript for the next reference to \f5np\fP.
+If the \f5name\fP argument is not \f5NULL\fP,
+it defines the value of the next subscript. 
+The \f5mode\fP argument can contain one or more of the following flags:
+.IP
+\f5ARRAY_ADD\fP:
+Add the subscript if not found.
+Otherwise, \f5nv_putsub()\fP returns \f5NULL\fP if the
+given subscript is not found.
+.IP
+\f5ARRAY_SCAN\fP:
+Begin a walk through the subscripts starting at the subscript
+given by \f5name\fP.  If \f5name\fP is \f5NULL\fP
+the walk is started from the beginning.
+.IP
+\f5ARRAY_UNDEF\fP:
+This causes any current scan to terminate and leaves the
+subscript in an undefined state.
+.PP
+If \f5ARRAY_ADD\fP is not given and the subscript
+does not exist, a \f5NULL\fP value is returned.
+.PP
+The \f5nv_nextsub()\fP function is used to advance to the
+next subscript.
+It returns 0 if there are no more subscripts or if called
+when not in a scan.
+.PP
+The \f5nv_setref()\fP function makes the name-value pair \f5np\fP
+into a reference to the variable whose name is given by
+the value of \f5np\fP.  The \f5nv_open()\fP open function is
+called with this name, the dictionary given by \f5dp\fP,
+and the \f5flags\fP argument.
+A \f5NULL\fP value causes the shell global variable dictionary to be searched.
+.PP
+The \f5nv_setvtree()\fP function makes the name-value pair \f5np\fP
+into a tree structured variable so that \f5nv_getval()\fP
+will return a string containing all the names and values of
+children nodes in a format that can be used in
+a shell compound assignment.

+.if \nZ=0 .I Rsh\^
+.if \nZ=1 .I Rksh\^
+.if \nZ=2 .I Rksh93\^

+.if \nZ=2 .IR ksh93 ;
+it is used to to execute commands with the attributes specified by
+the user's profiles (see
+.IR pfexec (1)).
+See
+.I Invocation\^
+below
+for the meaning of arguments to the shell.
+.SS Definitions.
+A
+.I metacharacter\^
+is one of the following characters:
+.PP
+.RS
+\f3;   &   (   )   \(bv   <   >   new-line   space   tab\fP
+.RE
+.PP
+A
+.I blank\^
+is a
+.B tab
+or a
+.BR space .
+An
+.I identifier\^
+is a sequence of letters, digits, or underscores
+starting with a letter or underscore.
+Identifiers are used as components of
+.I variable\^
+names.
+A
+.I vname\^
+is a sequence of one or more identifiers
+separated by a \fB\s+2.\s-2\fP and optionally preceded
+by a \fB\s+2.\s-2\fP.
+Vnames are used as function and variable names.
+A
+.I word\^
+is a sequence of
+.I characters\^
+from the character set defined by the current locale,
+excluding non-quoted
+.IR metacharacters .
+.PP
+A 
+.I command\^
+is a sequence of characters in the syntax
+of the shell language.
+The shell reads each command and
+carries out the desired action either directly or by invoking
+separate utilities.
+A built-in command is a command that is carried out by the
+shell itself without creating a separate process.
+Some commands are built-in purely for convenience
+and are not documented here.
+Built-ins that cause
+side effects in the shell environment and 
+built-ins that are found before performing a
+path search (see
+.I Execution\^
+below)
+are documented here.
+For historical reasons, some of
+these built-ins behave differently than
+other built-ins and are called
+.IR "special built-ins" .
+.SS Commands.
+A
+.I simple-command\^
+is a list of variable assignments
+(see
+.I Variable Assignments\^
+below)
+or a sequence of
+.I blank\^
+separated words
+which may be preceded by a list of variable assignments
+(see
+.I Environment\^
+below).
+The first word specifies the name of the command to
+be executed.
+Except as specified below,
+the remaining words are passed as arguments
+to the invoked command.
+The command name is passed as argument 0
+(see
+.IR exec (2)).
+The
+.I value\^
+of a simple-command is its exit status; 0-255
+if it terminates normally; 256+\f2signum\^\fP if
+it terminates abnormally (the name of the signal corresponding
+to the exit status can be
+obtained via the
+.B \-l
+option of the
+.B kill\^
+built-in utility).
+.PP
+A
+.I pipeline\^
+is a sequence of one or more
+.I commands\^
+separated by
+.BR \(bv .
+The standard output of each command but the last
+is connected by a
+.IR pipe (2)
+to the standard input of the next command.
+Each command,
+except possibly the last,
+is run as a separate process;
+the shell waits for the last command to terminate.
+The exit status of a pipeline is the exit
+status of the last command unless the
+.B pipefail
+option is enabled.
+Each pipeline can be preceded by the
+.I "reserved word"
+.B !
+which causes the exit status of the pipeline to become
+0 if the exit status of the last command is non-zero, and
+1 if the exit status of the last command is 0.
+.PP
+A
+.I list\^
+is a sequence of one or more
+pipelines
+separated by
+.BR ; ,
+.BR & ,
+.BR \(bv& ,
+.BR && ,
+or
+.BR \(bv\|\(bv ,
+and optionally terminated by
+.BR ; ,
+.BR & ,
+or
+.BR \(bv& .
+Of these five symbols,
+.BR ; ,
+.BR & ,
+and
+.B \(bv&
+have equal precedence,
+which is lower than that of
+.B &&
+and
+.BR \(bv\|\(bv .
+The symbols
+.B &&
+and
+.B \(bv\|\(bv
+also have equal precedence.
+A semicolon
+.RB ( ; )
+causes sequential execution of the preceding pipeline; an ampersand
+.RB ( & )
+causes asynchronous execution of the preceding pipeline (i.e., the shell does
+.I not\^
+wait for that pipeline to finish).
+The symbol
+.B \(bv&
+causes asynchronous execution of the preceding pipeline
+with a two-way pipe established to the parent shell;
+the standard input and output of the spawned pipeline
+can be written to and read from by the parent shell
+by applying
+the redirection operators
+.B <&
+and
+.B >&
+with arg
+.B p
+to commands and by using
+.B \-p
+option of
+the built-in commands
+.B read
+and
+.B print
+described later.
+The symbol
+.B &&
+.RB (\| \(bv\|\(bv \^)
+causes the
+.I list\^
+following it to be executed only if the preceding
+pipeline
+returns a zero (non-zero) value.
+One or more new-lines may appear in a
+.I list\^
+instead of a semicolon,
+to delimit a command.
+The first
+.I item \^
+of the first
+.I pipeline\^
+of a
+.I list\^
+that is a simple command not beginning
+with a redirection, and not occuring within a

+.PP
+If one of the above is preceded by a digit,
+with no intervening space, then the
+file descriptor number referred to is that specified
+by the digit
+(instead of the default 0 or 1).
+If one of the above, other than
+.BR >&\-

+forms,
+is preceded by
+.BI { varname }
+with no intervening space,

+the shell and stored in the variable
+.IR varname .
+If
+.B >&\-
+or the any of the
+.B >#
+and
+.B >#
+forms
+is preceded by
+.BI { varname }
+the value of
+.I varname\^
+defines the file descriptor to close or position.
+For example:
+.PP
+.RS
+\fB\&.\|.\|. \|2>&1\fR
+.RE
+.PP
+means file descriptor 2 is to be opened
+for writing as a duplicate
+of file descriptor 1 and
+.PP
+.RS
+\fBexec {n}<file\fR
+.RE
+.PP
+means open file named
+.B file
+for reading and store
+the file descriptor number in variable
+.BR n .
+.PP
+The order in which redirections are specified is significant.
+The shell evaluates each redirection in terms of the
+.RI ( "file descriptor" ", " file )
+association at the time of evaluation.
+For example:
+.PP
+.RS
+\fB\&.\|.\|. \|1>\f2fname\^\fP 2>&1\fR
+.RE
+.PP
+first associates file descriptor 1 with file
+.IR fname\^ .
+It then associates file descriptor 2 with the file associated with file
+descriptor 1 (i.e.
+.IR fname\^ ).
+If the order of redirections were reversed, file descriptor 2 would be associated
+with the terminal (assuming file descriptor 1 had been) and then file descriptor
+1 would be associated with file
+.IR fname\^ .
+.PP
+If a command is followed by
+.B &
+and job control is not active,
+then the default standard input
+for the command
+is the empty file
+.BR /dev/null .
+Otherwise, the environment for the execution of a command contains the
+file descriptors of the invoking shell as modified by
+input/output specifications.
+.SS Environment.
+The
+.I environment\^
+(see
+.IR environ (7))
+is a list of name-value pairs that is passed to
+an executed program in the same way as a normal argument list.
+The names must be
+.I identifiers\^
+and the values are character strings.
+The shell interacts with the environment in several ways.
+On invocation, the shell scans the environment
+and creates a
+variable
+for each name found,
+giving it the corresponding value and attributes and marking it
+.IR export .
+Executed commands inherit the environment.
+If the user modifies the values of these
+variables
+or creates new ones,
+using the
+.B export
+or
+.B typeset \-x
+commands, they become part of the
+environment.
+The environment seen by any executed command is thus composed
+of any name-value pairs originally inherited by the shell,
+whose values may be modified by the current shell,
+plus any additions
+which must be noted in
+.B export
+or
+.B typeset \-x
+commands.
+.PP
+The environment for any
+.I simple-command\^
+or function
+may be augmented by prefixing it with one or more variable assignments.
+A variable assignment argument is a word of the form
+.IR identifier=value .
+Thus:
+.PP
+.RS
+\fB\s-1TERM\s+1=450 \|cmd \|args\fR				and
+.br
+\fB(export \|\s-1TERM\s+1; \|\s-1TERM\s+1=450; \|cmd \|args)\fR
+.RE
+.PP
+are equivalent (as far as the above execution of
+.I cmd\^
+is concerned except for special built-in commands listed below \-
+those that are
+preceded with a dagger).
+.PP
+If the obsolete
+.B \-k
+option is set,
+.I all\^
+variable assignment arguments are placed in the environment,
+even if they occur after the command name.
+The following
+first prints
+.B "a=b c"
+and then
+.BR c :
+.PP
+.RS
+.nf
+.ft B
+echo \|a=b \|c
+set \|\-k
+echo \|a=b \|c
+.ft R
+.fi
+.RE
+This feature is intended for use with scripts written
+for early versions of the shell and its use in new scripts
+is strongly discouraged.
+It is likely to disappear someday.
+.SS Functions.
+.PP
+For historical reasons, there are two
+ways to define functions,
+the
+.IB name (\^)
+syntax and
+the
+.B function
+.I name\^
+syntax, described in the
+.I Commands
+section above.
+Shell functions are read in and stored internally.
+Alias names are resolved when the function is read.
+Functions are executed like commands with the arguments
+passed as positional parameters.
+(See
+.I Execution
+below.)
+.PP
+Functions defined by the
+.B function
+.I name
+syntax and called by name execute in the same process as the caller and
+share all files
+and present working directory with the
+caller.
+Traps caught by the caller are reset to their default action
+inside the function.
+A trap condition that is not caught or ignored by the
+function causes the function to terminate and the condition
+to be passed on to the caller.
+A trap on
+.SM
+.B EXIT
+set inside a function
+is executed
+in the environment
+of the caller
+after the function completes.
+Ordinarily,
+variables are shared between the calling program
+and the function.
+However,
+the
+.B typeset
+special built-in command used within a function
+defines local variables whose scope includes
+the current function.
+They can be passed to functions that they call in the
+variable assignment list the precedes the call or as arguments
+passed as name references.
+Errors within functions return control to the caller.
+.PP
+Functions defined with the
+.IB name (\^)
+syntax and functions defined with the
+.B function
+.I name
+syntax that are invoked with the \f3\s+2.\s-2\fP
+special built-in
+are executed in the caller's
+environment and share all variables
+and traps with the caller.
+Errors within these function executions cause the script that contains
+them to abort.
+.PP
+The special built-in command
+.B return
+is used to return
+from function calls.
+.PP
+Function names
+can be listed with the
+.B \-f
+or
+.B +f
+option of the
+.B typeset
+special built-in command.
+The text of functions, when available, will also
+be listed with
+.BR \-f .
+Functions can be undefined with the
+.B \-f
+option of the
+.B unset
+special built-in command.
+.PP
+Ordinarily, functions are unset when the shell executes a shell script.
+Functions that need to be defined across separate
+invocations of the shell should
+be placed in a directory and the
+.B
+.SM
+FPATH
+variable should contain the name of this directory.
+They may also
+be specified in the
+.B
+.SM
+ENV
+file.
+.SS Discipline Functions.
+Each variable can have zero or more discipline functions
+associated with it.
+The shell initially understands the discipline names \f3get\fP,
+\f3set\fP, \f3append\fP, and \f3unset\fP but on most systems
+others can be added at run time via the 
+C programming interface extension provided by the
+.B builtin
+built-in utility.
+If the \f3get\fP discipline is defined for a variable, it is invoked
+whenever the given variable is referenced.
+If the variable \f3.sh.value\fP is assigned a value inside
+the discipline function, the referenced variable will evaluate
+to this value instead.
+If the \f3set\fP discipline is defined for a variable, it is invoked
+whenever the given variable is assigned a value.
+If the \f3append\fP discipline is defined for a variable, it is invoked
+whenever a value is appended to the given variable.
+The variable \f3.sh.value\fP is given the value
+of the variable before invoking the discipline, and
+the variable will be assigned the value of \f3.sh.value\fP
+after the discipline completes.
+If \f3.sh.value\fP is unset inside the discipline, then
+that value is unchanged.
+If the \f3unset\fP discipline is defined for a variable, it is invoked
+whenever the given variable is unset.
+The variable will not be unset unless it is unset explicitly
+from within this discipline function.
+.PP
+The variable
+.B .sh.name
+contains the name of the variable for which the discipline function is called,
+.B .sh.subscript
+is the subscript of the variable, and
+.B .sh.value
+will contain the value being assigned inside the
+.B .set
+discipline function.
+For the \f3set\fP discipline,
+changing
+.B .sh.value
+will change the value that gets assigned.
+.SS Jobs.
+.PP
+If the
+.B monitor
+option of the
+.B set
+command is turned on,
+an interactive shell associates a \fIjob\fR with each pipeline.
+It keeps
+a table of current jobs, printed by the
+.B jobs
+command, and assigns them small integer numbers.
+When a job is started asynchronously with
+.BR & ,
+the shell prints a line which looks
+like:
+.PP
+.DT
+	[1] 1234
+.PP
+indicating that the job which was started asynchronously was job number
+1 and had one (top-level) process, whose process id was 1234.
+.PP
+This paragraph and the next require features that are
+not in all versions of UNIX and may not apply.
+If you are running a job and wish to do something else you may hit the key
+\fB^Z\fR (control-Z) which sends a STOP signal to the current job.
+The shell will then normally indicate that the job has been `Stopped',
+and print another prompt.
+You can then manipulate the state of this job,
+putting it in the background with the
+.B bg
+command, or run some other
+commands and then eventually bring the job back into the foreground with
+the foreground command
+.BR fg .
+A \fB^Z\fR takes effect immediately and
+is like an interrupt in that pending output and unread input are discarded
+when it is typed.
+.PP
+A job being run in the background will stop if it tries to read
+from the terminal.
+Background jobs are normally allowed to produce output,
+but this can be disabled by giving the command
+.BR "stty tostop" .
+If you set this
+tty option, then background jobs will stop when they try to produce
+output like they do when they try to read input.
+.PP
+There are several ways to refer to jobs in the shell.
+A job can be referred to by the process id of any process of the job
+or by one of the following:
+.PD 0
+.TP
+.BI % number
+The job with the given number.
+.TP
+.BI % string
+Any job whose command line begins with
+.IR string .
+.TP
+.BI %? string
+Any job whose command line contains
+.IR string .
+.TP
+.BI %%
+Current job.
+.TP
+.BI %+
+Equivalent to
+.BR %% .
+.TP
+.BI %\-
+Previous job.
+.PD
+.PP
+The shell learns immediately whenever a process changes state.
+It normally informs you whenever a job becomes blocked so that
+no further progress is possible, but only just before it prints
+a prompt.
+This is done so that it does not otherwise disturb your work.
+The
+.B notify
+option of the
+.B set
+command causes
+the shell to print these job change messages
+as soon as they occur.
+.PP
+When the
+.B monitor
+option is on, each background job that completes
+triggers any trap set for
+.BR CHLD .
+.PP
+When you try to leave the shell while jobs are running or stopped, you will
+be warned that `You have stopped(running) jobs.'
+You may use the
+.B jobs
+command to see what they are.
+If you immediately try to
+exit again, the shell will not warn you a second time, and the stopped
+jobs will be terminated.
+When a login shell receives a HUP signal, it sends
+a HUP signal to each job that has not been disowned with the
+.B disown
+built-in command described below.
+.SS Signals.
+The \s-1INT\s+1 and \s-1QUIT\s+1 signals for an invoked
+command are ignored if the command is followed by
+.B &
+and the
+.B monitor
+option is not active.
+Otherwise, signals have the values
+inherited by the shell from its parent
+(but see also
+the
+.B trap
+built-in command below).
+.SS Execution.
+Each time a command is read, the above substitutions
+are carried out.
+If the command name matches one
+of the
+.I "Special Built-in Commands\^"
+listed below,
+it is executed within the
+current shell process.
+Next, the command name is checked to see if
+it matches a user defined function.
+If it does,
+the positional parameters are saved
+and then reset to the arguments of the
+.I function\^
+call.
+A function is also executed in the
+current shell process.
+When the
+.I function\^
+completes or issues a
+.BR return ,
+the positional parameter list is restored.
+For functions defined with the
+.B function
+.I name\^
+syntax,
+any trap set on
+.SM
+.B EXIT
+within the function is executed.
+The exit value of a
+.I function\^
+is the value of the last command executed.
+If a command name is not a
+.I "special built-in command\^"
+or a user defined
+.IR function ,
+but it is one of the built-in commands listed below,
+it is executed in the current shell process.
+.PP
+The shell variable
+.B
+.SM PATH
+defines the search path for
+the directory containing the command.
+Alternative directory names are separated by
+a colon
+.RB ( : ).
+The default path is
+.B /bin:/usr/bin:
+(specifying
+.BR /bin ,
+.BR /usr/bin ,
+and the current directory
+in that order).
+The current directory can be specified by
+two or more adjacent colons, or by a colon
+at the beginning or end of the path list.
+If the command name contains a \f3/\fP, then the search path
+is not used.
+Otherwise, each directory in the path is
+searched for an executable file
+of the given name
+that is not a directory.
+If found, and if the shell
+determines that there is a built-in version
+of a command corresponding to a given pathname,
+this built-in is invoked in the current process.
+If found, and this directory is also contained in the value of the
+.B
+.SM FPATH
+variable,
+then this file is loaded into the current shell environment
+as if it were the argument to the \fB.\fP command
+except that only preset aliases are expanded,
+and a function of the given name is executed
+as described above.
+If not found, and the file
+.B .paths
+is found, and the this file contains a line of the form
+.BI FPATH= path
+where
+.I path\^
+names an
+existing directory, and this directory contains
+a file of the given name,
+then this file is loaded into the current shell environment
+as if it were the argument to the \fB.\fP special built-in command
+and a function of the given name is executed.
+Otherwise, if found,
+a process is created and
+an attempt is made to execute the command via
+.IR exec (2).
+.P
+When an executable is found, the directory where it is found
+in is searched for a file named
+.BR .paths .
+If this file is found and it contains a line of the form
+.BI BUILTIN_LIB= value\^
+, then the library named by
+.I value\^
+will be searched for as if it were an option argument to
+.BR "builtin -f" ,
+and if it contains a built-in of the specified name
+this will be executed instead of a command by this name.
+Otherwise, if this file is found and it contains a line of the form
+.IB name\^ = value\^
+in the first or second line, then the environment variable
+.I name\^
+is modified by prepending the directory specified by
+.I value\^
+to the directory list.
+If
+.I value\^
+is not an absolute directory, then it
+specifies a directory relative to the directory that the
+executable was found.
+If the environment variable
+.I name\^
+does not already exist it will be added to the environment
+list for the specified command.
+.P
+If the file has execute permission but is not an
+.B a.out
+file,
+it is assumed to be a file containing shell commands.
+A separate shell is spawned to read it.
+All non-exported variables are removed in this case.
+If the shell command
+file doesn't have read permission,
+or if the
+.I setuid
+and/or
+.I setgid
+bits are set on the file,
+then the shell executes an agent whose job it is to
+set up the permissions and execute the shell with the
+shell command file passed down as an open file.
+A parenthesized command is executed in
+a sub-shell without removing non-exported variables.
+.SS Command Re-entry.
+The text of the last
+.B
+.SM
+HISTSIZE
+(default 512)
+commands entered from a terminal device
+is saved in a
+.I history
+file.
+The file
+.B \s-1$HOME\s+1/.sh_history
+is used if the
+.B
+.SM
+HISTFILE
+variable is not set
+or if the file it names is not writable.
+A shell can access the commands of
+all
+.I interactive
+shells which use the same named
+.SM
+.BR HISTFILE .
+The built-in command
+.B hist\^
+is used to list or
+edit a portion of this file.
+The portion of the file to be edited or listed can be selected by
+number or by giving the first character or
+characters of the command.
+A single command or range of commands can be specified.
+If you do not specify an editor program as
+an argument to
+.B hist\^
+then the value of the variable
+.SM
+.B HISTEDIT
+is used.
+If
+.SM
+.B HISTEDIT
+is unset, the obsolete variable
+.SM
+.B FCEDIT
+is used.
+If
+.SM
+.B FCEDIT
+is not defined, then
+.B /bin/ed
+is used.
+The edited command(s) is printed and re-executed upon
+leaving the editor unless you quit without writing.
+The
+.B \-s
+option
+(and in obsolete versions, the editor name
+.BR \-\^ )
+is used to skip the editing phase and
+to re-execute the command.
+In this case a substitution parameter of the form
+\f2old\fP\f3=\fP\f2new\fP
+can be used to modify the command before execution.
+For example, with the preset alias
+.BR r ,
+which is aliased to
+.BR "\(fmhist \-s\(fm" ,
+typing
+`\f3r bad=good c\fP'
+will re-execute the most recent command which starts with the letter
+.BR c ,
+replacing the first occurrence of the string
+.B bad
+with the string
+.BR good .
+.SS In-line Editing Options.
+Normally, each command line entered from a terminal device is simply
+typed followed by a \f3new-line\fP (`RETURN' or `LINE\ FEED').
+If either the
+.BR emacs ,
+.BR gmacs ,
+or
+.B vi
+option is active, the user can edit the command line.
+To be in either of these edit modes
+.B set
+the corresponding
+option.
+An editing option is automatically selected each time the
+.SM
+.B VISUAL
+or
+.SM
+.B EDITOR
+variable is assigned a value ending in either of these
+option names.
+.PP
+The editing features require that the user's terminal
+accept `RETURN' as carriage return without line feed
+and that a space (`\ ') must overwrite the current character on
+the screen.
+.PP
+Unless the
+.B multiline
+option is on,
+the editing modes implement a concept where the user is looking through a
+window at the current line.
+The window width is the value of
+.SM
+.B COLUMNS
+if it is defined, otherwise 80.
+If the window width is too small to display the prompt and leave
+at least 8 columns to enter input, the prompt is truncated from the
+left.
+If the line is longer than the window width minus two, a mark is
+displayed at the end of the window to notify the user.
+As the cursor moves and reaches the window boundaries the window will be
+centered about the cursor.
+The mark is a
+.BR > " (<" ,
+.BR * )
+if the line extends on the
+right (left, both) side(s) of the window.
+.PP
+The search commands in each edit mode provide access to the history file.
+Only strings are matched, not patterns, although a leading
+.B ^
+in the string restricts the match
+to begin at the first character in the line.
+.PP
+Each of the edit modes has an operation to list the files
+or commands that match a partially entered word.
+When applied to the first word on the line,
+or the first word after a
+.BR ; , 
+.BR \(bv , 
+.BR & , 
+or
+.BR ( , 
+and the word does not begin with
+.B \(ap
+or contain a
+.BR / ,
+the list of aliases, functions, and executable commands
+defined by the
+.B
+.SM PATH
+variable that could match the partial word is displayed.
+Otherwise, the list of files that match the given
+word is displayed.
+If the partially entered word does not contain any
+file expansion characters, a
+.B *
+is appended before generating these lists.
+After displaying the generated list, the input line
+is redrawn.
+These operations are called command name listing and file name listing,
+respectively.
+There are additional operations, referred to as command name
+completion and file name completion, which compute the list
+of matching commands or files, but instead of printing the list,
+replace
+the current word with a complete or partial match.
+For file name completion,
+if the match is unique, a
+.B /
+is appended if the file is a directory and a space is
+appended if the file is not a directory.
+Otherwise, the longest common prefix for all the matching
+files replaces the word.
+For command name completion, only the portion of the file names
+after the last
+.B /
+are used to find the longest command prefix.
+If only a single name matches this prefix, then the
+word is replaced with the command name followed by a space.
+When using a
+.I tab\^
+for completion that does not yield a unique match,
+a subsequent
+.I tab\^
+will provide a numbered list of matching alternatives.
+A specific selection can be made by entering the
+selection number followed by a
+.IR tab .
+.SS Key Bindings.
+The
+.B
+.SM KEYBD
+trap can be used to intercept keys as they are typed
+and change the characters that are actually seen by
+the shell.
+This trap is executed after each character
+(or sequence of characters when the first character is ESC)
+is entered while reading from a terminal.
+The variable
+.B .sh.edchar
+contains the character or character sequence which
+generated the trap.
+Changing the value of
+.B .sh.edchar
+in the trap action causes the shell to behave as if the
+new value were entered from the keyboard rather than
+the original value.
+.PP
+The variable
+.B .sh.edcol
+is set to the input column number of the cursor at the time
+of the input.
+The variable
+.B .sh.edmode
+is set to
+ESC
+when in
+.B vi
+insert mode (see below) and is null otherwise.
+By prepending
+.B ${.sh.editmode}
+to a value assigned to
+.B .sh.edchar
+it will cause the shell
+to change to control mode if it is not already in this mode.
+.PP
+This trap is not invoked for characters entered as arguments to
+editing directives, or while reading input for a character search.
+.SS Emacs Editing Mode.
+This mode is entered by enabling either the
+.B emacs
+or
+.B gmacs
+option.
+The only difference between these two modes is the way
+they handle
+.BR ^T .
+To edit, the user
+moves the cursor to the point needing correction and
+then inserts or deletes characters or words as needed.
+All the editing commands are control characters or escape
+sequences.
+The notation for control characters is caret
+.RB ( ^ )
+followed
+by the character.
+For example,
+.B ^F
+is the notation for control
+.BR F .
+This is entered by depressing `f' while holding down the
+`CTRL' (control) key.
+The `SHIFT' key is
+.I not
+depressed.
+(The notation
+.B ^?
+indicates the DEL (delete) key.)
+.PP
+The notation for escape sequences is
+.B M-
+followed by a
+character.
+For example,
+.B M-f
+(pronounced Meta f)
+is entered by depressing ESC
+(ascii
+.BR 033 )
+followed by `f'.
+.RB ( M-F
+would be the notation for ESC followed by `SHIFT' (capital) `F'.)
+.PP
+All edit commands
+operate from any place on the line
+(not just at the beginning).
+Neither the `RETURN' nor the `LINE FEED' key is
+entered after edit commands except when noted.
+.PP
+.PD 0
+.TP 10
+.BI ^F

+To edit, the user enters

+mode by typing ESC

+Most control commands accept an optional repeat

+canonical processing is initially enabled and the
+command will be echoed again if the speed is 1200 baud or greater and it
+contains any control characters or less than one second has elapsed
+since the prompt was printed.
+The ESC character terminates canonical processing for the remainder of the command
+and the user can then modify the command line.

+echoing of raw mode.

+If the

+to execute it.
+Thus, it is possible to provide to the end-user shell procedures
+that have access to the full power of
+the standard shell,
+while imposing a limited menu of commands;
+this scheme assumes that the end-user does not have write and
+execute permissions in the same directory.
+.PP
+The net effect of these rules is that the writer of the
+.B .profile
+has complete control over user actions,
+by performing guaranteed setup actions
+and leaving the user in an appropriate directory
+(probably
+.I not\^
+the login directory).
+.PP
+The system administrator often sets up a directory
+of commands
+(e.g.,

+that can be safely invoked by
+.if \nZ=0 .BR rsh .
+.if \nZ=1 .BR rksh .
+.if \nZ=2 .BR rksh93 .
+.SH EXIT STATUS
+Errors detected by the shell, such as syntax errors,
+cause the shell
+to return a non-zero exit status.
+If the shell is being used non-interactively,
+then execution of the shell file is abandoned
+unless the error occurs inside a subshell in which case
+the subshell is abandoned.
+Otherwise, the shell returns the exit status of
+the last command executed (see also the
+.B exit
+command above).
+Run time errors detected by the shell are reported by
+printing the command or function name and the error condition.
+If the line number that the error occurred on is greater than one,
+then the line number is also printed in square brackets
+.RB ( "[]" )
+after the command or function name.

+.PP
+If a command
+is executed, and then a command with the same name is
+installed in a directory in the search path before the directory where the
+original command was found, the shell will continue to
+.I exec\^
+the original command.
+Use the
+.B \-t
+option of the
+.B alias\^
+command to correct this situation.
+.PP
+Some very old shell scripts contain a
+.B ^
+as a synonym for the pipe character
+.BR \(bv .
+.PP
+Using the
+.B hist\^
+built-in command within a compound command will cause the whole
+command to disappear from the history file.
+.PP
+The built-in command \f3\|.\fP \f2file\^\fP
+reads the whole file before any commands are executed.
+Therefore,
+.B alias
+and
+.B unalias
+commands in the file
+will not apply to any commands defined in the file.
+.PP
+Traps are not processed while a job is waiting for a foreground process.
+Thus, a trap on
+.B CHLD
+won't be executed until the foreground job terminates.
+.PP
+It is a good idea to leave a space after the comma operator in
+arithmetic expressions to prevent the comma from being interpreted
+as the decimal point character in certain locales.

+.H 1 "INTRODUCTION"
+.P
+The term "shell" is used to describe a program that provides
+a command language
+interface.
+Because the UNIX*\ 
+.FS *
+UNIX is a registered trademark of USL
+.FE
+system shell is a user level program, and not part of
+the operating system itself,
+anyone can write a new shell or modify an existing one.
+This has caused an evolutionary progress
+in the design and implementation of shells,
+with the better ones surviving.
+The most widely available UNIX system shells are the Bourne shell\*(Rf,
+.RS
+S. R. Bourne,

+The C Shell is available with all Berkeley Software Distribution (BSD) UNIX systems and on many other systems.
+The KornShell
+is available on System V Release 4 systems. 
+In addition, it is available on many other systems.
+The source for the KornShell language is available from the AT&T Toolchest,
+an electronic software distribution system.
+It runs on all known versions of the UNIX system and
+on many UNIX system look-alikes.

+.RF
+provides a more detailed comparison of the three shells,
+both as a command language and as a programming language.
+.P
+The KornShell language is a superset of the
+Bourne shell. The KornShell language has many of the popular C shell features,
+plus additional features of its own.
+Its initial popularity stems primarily from its improvements as
+a command language.
+The primary interactive benefit of the KornShell command language
+is a visual command line editor that allows you to
+make corrections to your current command line
+or to earlier command lines,
+without having to retype them.
+.P
+However,
+in the long run,
+the power of the KornShell language as a high-level programming language,
+as described by Dolotta and Mashey\*(Rf,
+.RS
+T. A. Dolotta and J. R. Mashey,
+.I "Using the shell as a Primary Programming Tool,"
+Proc. 2nd. Int. Conf. on Software Engineering, 1976,
+pages 169-176.
+.RF
+may prove to be of greater significance.
+\f5ksh-93\fP provides the programming power of several
+other interpretive languages such as \f5awk\fP,
+\f5FIT\fP,
+\f5PERL\fP,
+and
+\f5tcl\fP.
+An application that was originally written in the C programming language
+was rewritten in the KornShell language.
+More than 20,000 lines of C code were replaced with KornShell scripts
+totaling fewer than 700 lines.
+In most instances there was no perceptible difference in performance
+between the two versions of the code.
+.P
+The KornShell language has been embedded into windowing systems
+allowing graphical user interfaces to be developed in shell
+rather than having to build applications that need to be
+compiled.
+The \f5wksh\fP program\*(Rf
+.RS
+J. S. Pendergrast,
+.IR "WKSH - Korn Shell with X-Windows Support",
+USL. 1991.
+.RF
+provides a method of developing OpenLook or Motif
+applications as \f5ksh\fP scripts.
+.P
+This memo is an introduction to \f5ksh-93\fP,
+the program that implements an enhanced version
+of the KornShell language.
+It is referred to as \f5ksh\fP in the rest of this memo.
+The memo describes the KornShell language based on the
+features of the 12/28/93 release of \f5ksh\fP.
+This memo is not a tutorial, only an introduction.
+The second edition of reference [9] gives 
+a more complete treatment of the KornShell language.
+.P
+A concerted effort has been made to achieve both System V Bourne shell
+compatibility and IEEE POSIX compatibility
+so that scripts written for either of these shells
+can run without modification with \f5ksh\fP.
+In addition, \f5ksh-93\fP attempts to
+be compatible with older versions of \f5ksh\fP.
+When there are conflicts between versions of the shell,
+\f5ksh-93\fP selects the behavior dictated by the IEEE POSIX
+standard.
+The description of features in this memo assumes
+that the reader is already familiar with the Bourne shell.
+.H 1 "COMMAND LANGUAGE"
+There is no separate command language.
+All features of the language, except job control,
+can be
+used both within a script and interactively from a terminal.
+However, features that are more likely to be used
+while running commands interactively from a terminal
+are presented here.
+.H 2 "Setting Options"
+By convention, UNIX commands
+consist of a command name followed by options and other arguments.
+Options are either of the form \f5-\fP\fIletter\fP,
+or \f5-\fP\fIletter value\fP.
+In the former case, several options may be grouped after a single \f5-\fP.
+The argument \f5--\fP signifies an end to the option list and is
+only required when the first non-option argument begins with
+a \f5-\fP.
+Most commands print an error message which
+shows which options are permitted
+when given incorrect arguments.
+In addition, the option sequence \f5-?\fP causes most commands
+to print a usage message which lists the valid options. 
+.P
+Ordinarily, \f5ksh\fP executes a command by 
+using the command name to locate a program to run
+and by running the program as a separate process.
+Some commands, referred to as
+.IR built-ins ,
+are carried out by \f5ksh\fP itself,
+without creating a separate process.
+The reasons that some commands are built-in are presented later.
+In nearly all cases the distinction
+between a command that is built-in and one that
+is not is invisible to the user.
+However, nearly
+all commands that are built-in follow command line conventions.
+.P
+\f5ksh\fP has several options that can be set by the user
+as command line arguments at invocation and as option arguments to the
+\f5set\fP command.
+Most other options can be set with a single letter option or as a name
+that follows the \f5-o\fP option. 
+Use
+\f5set\ -o\fP
+to display the current option settings.
+Some of these options, such as
+.B interactive
+and
+.B monitor
+(see
+.I "Job Control"
+below),
+are enabled automatically by \f5ksh\fP
+when the shell is connected to a terminal device.
+Other options, such as
+.B noclobber
+and
+.BR ignoreeof ,
+are normally placed in a startup file.
+The
+.B noclobber
+option causes
+\f5ksh\fP
+to print an error message when you use
+.B >
+to redirect output to a file that already exists.
+If you want to redirect to an existing file, then
+you have to use
+.B >|
+to override
+the
+.B noclobber
+option.
+The
+.B ignoreeof
+option
+is used to prevent the
+.I end-of-file
+character, normally
+.B ^D
+(Control- d),
+from exiting the shell and possibly logging you out.
+You must type \f5exit\fP
+to log out.
+Most of the options are described in this memo as appropriate. 
+.H 2 "Command Aliases"
+.P
+Command aliases provide a mechanism of associating a command name and
+arguments with a shorter name.
+Aliases are defined with the \f5alias\fP
+built-in.
+The form of an \f5alias\fP
+command definition is:
+.ce
+\f5alias\fP \fIname\fP\f5=\fP\fIvalue\fP
+As with most other shell assignments, no space is allowed before or after
+the \f5=\fP.
+The characters of an alias name cannot be characters that are
+special to the shell. 
+The replacement string,
+.I value,
+can contain any valid shell script,
+including meta-characters such as pipe symbols and i/o-redirection
+provided that they are quoted.
+Unlike
+\f5csh\fP,
+aliases in
+\f5ksh\fP
+cannot take arguments.
+The equivalent functionality of aliases with arguments can
+be achieved with shell functions, described later.
+.P
+As a command is being read,
+the command name is checked against a list of
+.I alias
+names.
+If it is found,
+the name is replaced by the alias value associated with the
+.I alias
+and then rescanned.
+When rescanning the value for an alias, alias substitutions
+are performed except for an alias that is currently being processed.
+This prevents infinite loops in alias substitutions.
+For example with the aliases, \f5alias\ l=ls\ 'ls=ls\ -C'\fP,
+the command name \f5l\fP becomes \f5ls\fP, which becomes \f5ls\ -C\fP.
+Ordinarily, only the command name word is processed for alias substitution.
+However, if the value of an alias ends in a space,
+then the word following the alias is also checked for alias substitution.
+This makes it possible
+to define an alias whose first argument is the name of a command
+and have alias substitution performed on this argument,
+for example
+\f5nohup='nohup\ '\fP.
+.P
+Aliases can be used to redefine built-in commands so that
+the alias,
+.ce
+\f5alias test=./test\fP
+can be used to look for \f5test\fP
+in your current working directory rather than
+using the built-in \f5test\fP command.
+Reserved words such as
+\f5for\fP and \f5while\fP
+cannot be changed by aliasing.
+The command \f5alias\fP,
+without arguments, generates
+a list of aliases and corresponding alias values.
+The \f5unalias\fP command removes the name and text of an alias.
+.P
+Aliases are used to save typing and to improve readability of scripts.
+Several aliases are predefined by \f5ksh\fP.
+For example, the predefined alias
+.ce
+\f5alias integer='typeset -i'\fP
+allows the integer variables \f5i\fP and \f5j\fP
+to be declared and initialized with the command
+.ce
+\f5integer i=0 j=1\fP
+.P
+While aliases can be defined in scripts,
+it is not recommended.
+The location of an alias command can be important
+since aliases are only processed when a command is read.
+A \fB\s+2.\s-2\fP
+procedure (the shell equivalent of an include file)
+is read all at once (unlike
+start up files
+which are read a command at
+a time) so that any aliases defined there will not effect any commands
+within this script.
+Predefined aliases do not have this problem.
+.H 2 "Command Re-entry"
+.P
+When run interactively,
+\f5ksh\fP saves the
+commands you type at a terminal in a file.
+If the variable
+\fB\s-1HISTFILE\s+1\fP
+is set to the name of a file to which the user
+has write access,
+then the commands are stored in this
+.I history
+file.
+Otherwise the file
+\fB$\s-1HOME\s+1/.sh_history\fP
+is checked for write access and if this fails
+an unnamed file is used to hold the history lines.
+Commands are always appended to this file.
+Instances of \f5ksh\fP
+that run concurrently and use the same history file
+name, share access to the history file so that a command
+entered in one shell will be available for editing in another
+shell.
+The file may be truncated when \f5ksh\fP
+determines that no other shell is using the history file.
+The number of commands accessible to the user is determined by the value of the
+\fB\s-1HISTSIZE\s+1\fP
+variable at the time the shell is invoked.
+The default value is 256.
+Each command may consist of one or more lines since a compound
+command is considered one command.
+If the character
+.B !
+is placed within the
+.I "primary prompt"
+string,
+\fB\s-1PS1\s+1\fP,
+then it is replaced by the command number each time the prompt is given.
+.P
+A built-in command named \f5hist\fP
+is used to list and/or edit
+any of these saved commands.
+The option
+.B \-l
+is used to specify listing of previous commands.
+The command can always be specified with
+a range of one or more commands.
+The range can be specified by giving the command
+number, relative or absolute, or by giving
+the first character or characters of the command.
+When given without specifying the range,
+the last 16
+commands are listed, each
+preceded by the command number.
+.P
+If the listing option is not selected,
+then the range of commands specified,
+or the last command if no range is given,
+is passed to an editor program before
+being re-executed by \f5ksh\fP.
+The editor to be used may be specified
+with the option
+.B \-e
+and following it with the editor name.
+If this option is not specified, the
+value of the shell variable
+\fB\s-1HISTEDIT\s+1\fP
+is used as the name of the editor,
+providing that this variable has a non-null value.
+If this variable is not set, or is null,
+and the
+.B \-e
+option has not been selected,
+then
+\f5/bin/ed\fP
+is used.
+When editing has been complete,
+the edited text automatically becomes
+the input for \f5ksh\fP.
+As this text is read by \f5ksh\fP, it is echoed onto the terminal.
+.P
+The 
+.B \-s
+option causes the editing to be bypassed
+and just re-executes the command.
+In this case only a single command can be specified as the range
+and an optional argument of the form
+\fIold\fP\fB=\fP\fInew\fP
+may be added which requests a simple string substitution
+prior to evaluation.
+A convenient alias,
+.ce
+\f5alias r='hist -s'\fP
+has been pre-defined so that
+the single key-stroke
+\f5r\fP
+can be used to re-execute the previous command
+and the key-stroke sequence,
+\f5r\ abc=def\ c\fP
+can be used to re-execute the last command that starts with
+the letter \f5c\fP
+with the first occurrence of the string \f5abc\fP
+replaced with the string \f5def\fP.
+Typing
+\f5r\ c\ >\ file\fP
+re-executes the most recent command starting with the letter \f5c\fP,
+with standard output redirected to
+.IR file .
+.H 2 "In-line editing"
+.P
+Lines typed from a terminal frequently need changes made
+before entering them.
+With the Bourne shell the only method to fix up commands
+is by backspacing or killing the whole line.
+\f5ksh\fP offers options that allow the user to edit parts of the
+current command line before submitting the command.
+The in-line edit options make the command line into a single
+line screen edit window.
+When the command is longer than the width of the terminal,
+only a portion of the command is visible.
+Moving within the line automatically makes that portion visible.
+Editing can be performed on this window until the
+.I return
+key is pressed.
+The editing modes have editing directives that access the history file
+in which previous commands are saved.
+A user can copy any of the most recent
+\fB\s-1HISTSIZE\s+1\fP
+commands from this file into the input edit window.
+You can locate commands by searching or by position.
+.P
+The in-line editing options do not use the
+.I termcap
+or
+.I terminfo
+databases.
+They work on most standard terminals.
+They only require that the backspace character moves the cursor left
+and the space character overwrites the current character on the screen
+and moves the cursor to the right.
+Very few terminals or terminal emulators do not have
+this behavior.
+.P
+There is a choice of editor options.
+The
+.BR emacs ,
+.BR gmacs ,
+or
+.B vi
+option is selected by turning on the
+corresponding
+option of the \f5set\fP
+command.
+If the value of the
+\fB\s-1EDITOR\s+1\fP
+or
+\fB\s-1VISUAL\s+1\fP
+variables ends with any of these suffixes
+the corresponding option is turned on.
+A large subset of each of these editors'
+features is available within the shell.  Additional
+functions, such as file name completion, have also been added.
+.P
+In the
+.B emacs
+or
+.B gmacs
+mode the user positions the cursor to the point
+needing correction and inserts, deletes, or replaces
+characters as needed.
+The only difference between these two modes is the
+meaning of the directive
+.BR ^T .
+Control keys and escape sequences are used for cursor
+positioning and control functions.
+The available editing functions are listed in the manual page.
+.P
+The
+.B vi
+editing mode
+starts in insert mode and enters control mode when the
+user types ESC ( 033 ).
+The
+.I return
+key, which submits the current command for processing,
+can be entered from either mode.
+The cursor can be anywhere on the line.
+A subset of commonly used
+.I vi
+editing directives are available.
+The
+.B k
+and
+.B j
+directives that normally move up and down by one
+.IR line ,
+move up and down one
+.I command
+in the history file,
+copying the command into the input edit window.
+For reasons of efficiency,
+the terminal is kept in canonical mode until an
+ESC
+is typed.
+On some terminals,
+and on earlier versions of the UNIX operating system,
+this doesn't work correctly.
+The
+.B viraw
+option,
+which always uses
+.I raw
+or
+.I cbreak
+mode,
+must be used in this case.
+.P
+Most of the code for the editing options does not rely on the
+\f5ksh\fP code and can be used in a stand-alone mode with most any command
+to add in-line edit capability.
+However,
+all versions of the in-line editors have some features that
+use some shell specific code.  For example,
+with all edit modes, the
+ESC-=
+directive applied to command words
+(the first word on the line,
+or the first word after a
+.BR ; ,
+.BR | ,
+.BR ( ,
+or
+.BR & )
+lists all aliases, functions, or commands
+that match the portion of the given current word.
+When applied to other words, this directive
+prints the names of files that match the current
+word.
+The ESC\fB-*\fP directive
+adds the expanded list of matching files to the command line.
+A trailing
+.B *
+is added to the word if it doesn't contain any file pattern matching
+characters before the expansion.
+In
+.B emacs
+and
+.B gmacs
+mode,
+ESC-ESC
+indicates command completion when applied to
+command names, otherwise it indicates pathname completion.
+With command or pathname completion,
+the list generated by the
+ESC-= directive is examined to find
+the longest common prefix.
+With command completion, only the last component of
+the pathname is used to compute the longest command prefix.
+If the longest common prefix is a complete match,
+then the word is replaced by the pathname, and a
+.B /
+is appended if
+pathname is a directory, otherwise a space is added.
+In
+.B vi
+mode,
+.B \e
+from control mode gives the same behavior.
+.H 2 "Key Binding"
+.P
+It is possible to intercept keys as they are entered and
+apply new meanings or bindings.
+A trap named
+\fB\s-1KEYBD\s+1\fP
+is evaluated each time
+\f5ksh\fP processes characters entered
+from the keyboard,  
+other than those typed
+while entering a search string or an argument to an
+edit directive such as
+.B r
+in vi-mode.
+The action associated with this trap can change the value of
+the entered key to cause the key to perform a different
+operation.
+.P
+When the
+\fB\s-1KEYBD\s+1\fP
+trap is entered,
+the \fB.sh.edtext\fP
+variable contains the contents of the current input line
+and the \fB.sh.edcol\fP
+variable gives the current cursor position within this line.
+The \fB.sh.edmode\fP
+variable contains the
+.B ESC
+character when the trap is entered from
+.B vi
+insert mode.
+Otherwise, this value is null.
+The \fB.sh.edchar\fP
+variable contains the character or
+escape sequence that caused the trap.
+A key sequence is either a single character,
+.B ESC
+followed by a single character,
+or
+.B ESC[
+followed by a single character.
+In the \fBvi\fP edit mode,
+the characters after the
+.B ESC
+must be entered within half a second after the
+.BR ESC .
+The value of \fB.sh.edchar\fP
+at the end of the trap will be used as
+the input sequence. 
+.P
+Using the associative array facility of \f5ksh\fP described later,
+and the function facility of \f5ksh\fP, it is easy to write
+a single trap so that keys can be bound dynamically.  For example,
+.sp
+.nf
+.in .5i
+.ta 4i
+\f5typeset -A Keytable
+trap 'eval "${Keytable[${.sh.edchar}]}"' KEYBD
+function keybind # key action
+{ 
+        typeset key=$(print -f "%q" "$2")
+        case $# in
+        2)      Keytable[$1]='.sh.edchar=${.sh.edmode}'"$key"
+                ;;
+        1)      unset Keytable[$1]
+                ;;
+        *)      print -u2 "Usage: $0 key [action]"
+                ;;
+        esac
+}\fP
+.ta
+.in
+.fi
+.sp
+.H 2 "Job Control"
+.P
+The job control mechanism 
+is almost identical to the version introduced in \f5csh\fP
+of the Berkeley UNIX operating system,
+version 4.1 and later.
+The job control feature allows the user to stop and
+restart programs, and to move programs to and from the
+foreground and the background.
+It will only work on systems that provide support for
+these features.
+However,
+even systems without job control have a
+.B monitor
+option which, when enabled, will report the progress
+of background jobs and enable the user to \f5kill\fP
+jobs by job number or job name.
+.P
+An interactive shell associates a
+.I job
+with each pipeline typed in from the terminal
+and assigns it a small integer number
+called the job number.
+If the job is run asynchronously,
+the job number is printed at the terminal.
+At any given time, only one job owns the terminal,
+i.e., keyboard signals are only sent to the processes in one job.
+When \f5ksh\fP creates a foreground job,
+it gives it ownership of the terminal.
+If you are running a job and wish to stop
+it you hit the key
+.B ^Z
+(control-\fBZ\fP)
+which sends a
+\fB\s-1STOP\s+1\fP
+signal to all processes in the current job.
+The shell receives notification that the processes
+have stopped and takes back control of the terminal.
+.P
+There are commands to continue programs in the foreground
+and background.
+There are several ways to refer to jobs.
+The character
+.B %
+introduces a job name.
+You can refer to jobs by name or number as described in the manual page.
+The built-in command \f5bg\fP
+allows you to continue a job in the background,
+while the built-in command \f5fg\fP
+allows you to continue a job in the foreground even
+though you may have started it in the background.
+.P
+A job being run in the background will stop if it tries
+to read from the terminal.
+It is also possible to stop background jobs that try to write on
+the terminal by setting the terminal options
+appropriately.
+.P
+There is a built-in command \f5jobs\fP
+that lists the status of all running and stopped jobs.
+In addition,
+you are informed of the change of state (running or stopped)
+of any background
+jobs just before each prompt.
+If you want to be notified about background job completions
+as soon as they occur without waiting for a prompt, then use the
+.B notify
+option.
+When you try to exit the shell while jobs are stopped or running,
+you will receive a message from \f5ksh\fP.
+If you ignore this message and try to exit again,
+all stopped processes will be terminated.
+In addition, for login shells, the
+\fB\s-1HUP\s+1\fP
+signal will be sent to
+all background jobs
+unless the job has been disowned with the
+.B disown
+command.
+.P
+A built-in version of \f5kill\fP
+makes it possible to use
+.I job
+numbers as targets for signals.
+Signals can be selected by number or name.
+The name of the signal is the name found in the
+.I include
+file
+.B /usr/include/sys/signal.h
+with the prefix
+.B \s-1SIG\s+1
+removed.
+The
+.B \-l
+option of \f5kill\fP 
+provides a means to map individual signal names to and from
+signal number.
+In addition, if no signal name or number is given,
+\f5kill\ -l\fP 
+generates a list of valid signal names.
+.H 2 "Changing Directories"
+By default,
+\f5ksh\fP
+maintains a logical view of the file system hierarchy
+which makes symbolic links transparent.
+For systems that have symbolic links,
+this means that if \f5/bin\fP is a symbolic link to \f5/usr/bin\fP
+and you change directory to \f5/bin\fP, \f5pwd\fP will indicate
+that you are in \f5/bin\fP, not \f5/usr/bin\fP. 
+\f5pwd\ -P\fP
+generates the physical pathname of the present working
+directory by resolving all the symbolic links.
+By default,
+the \f5cd\fP
+command will take you where you expect to go even if you cross
+symbolic links.
+A subsequent \f5cd\ ..\fP in the example above
+will place you in \f5/\fP, not \f5/usr\fP.
+On systems with symbolic links,
+\f5cd\ -P\fP
+causes
+.B ..
+to be treated physically.
+.P
+\f5ksh\fP remembers your last directory
+in the variable
+\fB\s-1OLDPWD\s+1\fP.
+The \f5cd\fP
+built-in can be given with argument
+.B \-
+to return to the previous directory
+and print the name of the directory.
+Note that \f5cd\ -\fP
+done twice returns you to the starting directory,
+not the second previous directory.
+A directory
+.I stack
+manager has been written as shell
+.I functions
+to
+.I push
+and
+.I pop
+directories from the stack.
+.H 2 "Prompts"
+.P
+When \f5ksh\fP
+reads commands from a terminal,
+it issues a prompt whenever it is ready
+to accept more input and then
+waits for the user to respond.
+The
+\fB\s-1TMOUT\s+1\fP
+variable
+can be set to be the number of seconds that the shell will wait for
+input before terminating.
+A 60 second warning message is printed
+before terminating.
+.P
+The shell uses two prompts.
+The primary prompt,
+defined by the value of the
+\fB\s-1PS1\s+1\fP
+variable,
+is issued at the start of each command.
+The secondary prompt,
+defined by the value of the
+\fB\s-1PS2\s+1\fP
+variable,
+is issued when more input is needed to complete a command.
+.P
+\f5ksh\fP allows the user to specify a list of files or directories
+to check before issuing the
+\fB\s-1PS1\s+1\fP
+prompt.
+The variable
+\fB\s-1MAILPATH\s+1\fP
+is a colon (
+.B :
+) separated list of file names to be checked for changes
+periodically. The user is notified
+before the next prompt.
+Each of the names in this list can be followed by a
+.B ?
+and a message to be given when a change has been detected in the file.
+The prompt will be evaluated for parameter expansion, command
+substitution and arithmetic expansion which are described later.
+The parameter
+.B $_
+within a mail message will evaluate to the name of the file that
+has changed.
+The parameter
+\fB\s-1MAILCHECK\s+1\fP
+is used to specify the minimal interval in seconds before
+new mail is checked for.
+.P
+In addition to replacing each
+.B !
+in the prompt with the command number,
+\f5ksh\fP expands
+the value of the
+.B \s-1PS1\s+1
+variable
+for parameter expansions, arithmetic expansions,
+and command substitutions as described below
+to generate the prompt.
+The expansion characters that are to be applied when
+the prompt is issued must be quoted to prevent the
+expansions from occurring when assigning the value to
+.B \s-1PS1\s+1.
+For example,
+\f3\s-1PS1\s+1="$\s-1PWD\s+1"\fP
+causes 
+.B \s-1PS1\s+1
+to be set to the value of
+.B \s-1PWD\s+1
+at the time of the assignment whereas
+.B \s-1PS1\s+1='$\s-1PWD\s+1'
+causes
+.B \s-1PWD\s+1
+to be expanded at the time the prompt is issued.
+.P
+Command substitution may require a separate process
+to execute and cause the prompt display to be somewhat
+slow, especially
+when the return key is pressed several times in a row.
+Therefore, its use
+within
+.B \s-1PS1\s+1
+is discouraged.
+Some variables are maintained by \f5ksh\fP
+so that their values can be used with
+.B \s-1PS1\s+1.
+The
+.B \s-1PWD\s+1
+variable stores the pathname of the current working directory.
+The value of 
+.B \s-1SECONDS\s+1
+variable
+is the value of the most
+recent assignment plus the elapsed time.
+By default, the time is measured in milli-seconds,
+but since
+.B \s-1SECONDS\s+1
+is a floating point variable, the
+number of places after the decimal point in the expanded
+value can be
+specified with
+\f5typeset\ -F\fP\fIplaces\fP\f5\ SECONDS\fP.
+In a roundabout way, this variable
+can be used to generate a time stamp into the
+.B \s-1PS1\s+1
+prompt without creating a process at each prompt.
+The following code explains how you can do this on
+System V.  On BSD, you need a different command to initialize
+the
+.B \s-1SECONDS\s+1
+variable.
+\f5
+.sp
+.nf
+.in .5i
+# . this script and use $TIME as part of your PS1 string to
+# get the time of day in your prompt
+typeset -RZ2  _x1 _x2 _x3
+(( SECONDS=$(date  '+3600*%H+60*%M+%S') ))
+_s='_x1=(SECONDS/3600)%24,_x2=(SECONDS/60)%60,_x3=SECONDS%60,0'
+TIME='"${_d[_s]}$_x1:$_x2:$_x3"'
+# PS1=${TIME}whatever
+.fi
+.ta
+.in
+.sp
+\fP
+.H 2 "Tilde substitution"
+.P
+The character
+.B \(ap
+at the beginning of a word has special meaning to \f5ksh\fP.
+If the characters after the
+.B \(ap
+up to a
+.B /
+match a user login name in the password database, then the
+.B \(ap
+and the name are replaced by
+that user's login directory.
+If no match is found, the original word
+is unchanged.
+A
+.B \(ap
+by itself, or in front of a
+.BR / ,
+is replaced by the value of the
+\fB\s-1HOME\s+1\fP
+parameter.
+A
+.B \(ap
+followed by a
+.B +
+or
+.B \-
+is replaced by the value of
+.B $\s-1PWD\s+1
+or
+.B $\s-1OLDPWD\s+1
+respectively.
+.H 2 "Output formats"
+The output of built-in commands and traces have values quoted so that they
+can be re-input to the shell.
+This makes it easy to cut and paste shell output on systems
+which use a pointing device such as a mouse.
+In addition, output can be saved in a file for reuse.
+.P
+.H 2 "The \fB\s-1ENV\s+1\fP file"
+When an interactive \f5ksh\fP starts, it evaluates the
+.B $\s-1ENV\s+1
+variable to arrive at a file name.
+If this value is not null,
+\f5ksh\fP attempts to read and process
+commands in a file by this name.
+Earlier versions of \f5ksh\fP read the \fB\s-1ENV\s+1\fP file
+for all invocations of the shell primarily to allow
+function definitions to be available for all shell
+invocations.
+The function search path, \fB\s-1FPATH\s+1\fP, described later,
+eliminated the primary need for this capability and it was
+removed because the high performance cost was no longer
+deemed acceptable.
+.H 1 "PROGRAMMING LANGUAGE"
+The KornShell vastly extends the set of applications that
+can be implemented efficiently at the shell level.
+It does this by providing simple yet powerful mechanisms
+to perform arithmetic, pattern matching,
+substring generation,
+and arrays.
+Users can write applications as separate functions that can
+be defined in the same file or in a library of functions
+stored in a directory and loaded on demand.
+.H 2 "String Processing"
+The shell is primarily a string processing language.
+By default, variables hold variable length strings.
+There are no limits to the length of strings.  Storage
+management is handled by the shell automatically.
+Declarations are not required.
+With most programming languages, string constants are designated
+by enclosing characters in single quotes or double quotes.
+Since most of the words in the language are strings, the shell
+requires quotes only when a string contains characters that
+are normally processed specially by the shell, but their
+literal meaning is intended.
+However, since the shell is a string processing language,
+and some characters can occur as literals and as language metacharacters,
+quoting is an important part of the language.
+.P
+There are four quoting mechanisms in \f5ksh\fP.
+The simplest is to enclose a sequence of characters inside single quotes.
+All characters between a pair of single quotes have their literal meaning;
+the single quote itself cannot appear.
+A
+.B $
+immediately preceding
+a single quoted string
+causes all the characters until the matching single quote
+to be interpreted as an ANSI-C language string.
+Thus, \f5'\en'\fP represents characters \f5\e\fP and
+\f5n\fP, whereas, \f5$'\en'\fP 
+represents the new-line character.
+Double quoted strings remove the special meaning of all characters
+except
+.BR $ ,
+.BR \(ga ,
+and
+.BR \e ,
+so that parameter expansion and command substitution (defined below)
+are performed.
+The final mechanism for quoting a character is by preceding it with the
+escape character
+.BR \e\^ .
+This mechanism works outside of quoted strings and for the characters
+.BR $ ,
+.BR \(ga ,
+\fB"\fP,
+and
+.B \e
+in double quoted strings.
+.P
+Variables are designated by
+one or more
+strings of alphanumeric
+characters beginning with an alphabetic character
+separated by a \fB\s+2.\s-2\fP.
+Upper and lower case characters are distinct, so that the variable
+.B A
+and
+.B a
+are names of different variables.
+There is no
+limit to the length of the name of a variable.
+You do not have to declare variables.
+You can assign a value to a variable by writing the name of the
+variable, followed by an equal sign, followed by a character string
+that represents its value.
+To create a variable whose name
+contains a \fB\s+2.\s-2\fP,
+the variable whose name consists of
+the characters before the last \fB\s+2.\s-2\fP
+must already exist.
+You reference a variable by
+putting the name inside curly braces and
+preceding the braces with a dollar sign.
+The braces may be omitted when the name
+is alphanumeric.
+If \f5x\fP and \f5y\fP
+are two shell variables, then
+to define a new variable,
+\f5z\fP,
+whose value is
+the concatenation of the values of
+\f5x\fP and \f5y\fP,
+you just say
+\f5z=$x$y\fP.
+It is that easy.
+.P
+The
+.B $
+can be thought of as meaning
+"value of."
+You can also capture the output of any command with the notation
+.BI $( command ) .
+This is referred to as command substitution.
+For example,
+\f5x=$(date)\fP
+assigns the output from the \f5date\fP
+command to the variable \f5x\fP.
+Command substitution in the
+Bourne shell is denoted by enclosing the command between
+backquotes,
+(\fB\(ga\^\(ga\fP).
+This notation
+suffers from some
+complicated quoting rules.
+Thus, it is hard to write \f5sed\fP
+patterns which contains back slashes within command substitution.
+Putting the pattern in single quotes
+is of little help.
+\f5ksh\fP accepts the Bourne shell command substitution syntax
+for backward compatibility.
+The
+.BI $( command )
+notation allows
+the \fIcommand\fP itself to contain quoted strings even if the substitution
+occurs within double quotes. Nesting is legal.
+.P
+The special command substitution of the form
+\f5$(cat\ file)\fP
+can be replaced by
+\f5$(<\ file)\fP,
+which is faster because
+the \f5cat\fP
+command doesn't have to run.
+.H 2 "Shell Parameters and Variables"
+.P
+There are three types of parameters used by \f5ksh\fP,
+special parameters, positional parameters, and named
+parameters which are called variables.
+\f5ksh\fP defines the same special parameters,
+.BR 0 ,
+.BR * ,
+.BR @ ,
+.BR # ,
+.BR ? ,
+.BR $ ,
+.BR ! ,
+and
+.BR \- ,
+as in the Bourne shell.
+.P
+Positional parameters are set when the shell is invoked,
+as arguments to the \f5set\fP built-in,
+and by calls to functions (see below) and \fB\s+2.\s-2\fP
+procedures.
+They are named by numbers starting at 1.
+.P
+The third type of parameter is a variable.
+As mentioned earlier,
+\f5ksh\fP uses variables whose names
+consist of one or more
+alpha-numeric strings separated by a \fB\s+2.\s-2\fP.
+There is no need to specify the
+.I type
+of a variable in the shell because, by default,
+variables store strings of arbitrary length
+and values will automatically be converted to numbers
+when used in an arithmetic context.
+However, \f5ksh\fP variables
+can have one or more
+.I attributes
+that control the internal representation of the variable,
+the way the variable is printed, and its access or
+scope.
+In addition,
+\f5ksh\fP
+allows variables to represent arrays of values
+and references to other variables.
+The \f5typeset\fP
+built-in command of \f5ksh\fP
+assigns attributes to variables.
+Two of the attributes,
+.I readonly
+and
+.IR export ,
+are available in the Bourne shell.
+Most of the remaining attributes are discussed here.
+The complete list of attributes appears in the manual.
+The \f5unset\fP
+built-in of \f5ksh\fP removes
+values and attributes of variables.
+When a variable is exported, certain of its attributes are also exported.
+.P
+Whenever a value is assigned to a variable,
+the value is transformed according to the attributes of the variable.
+Changing the attribute of a variable can change its value.
+The attributes
+.B \-L
+and
+.B \-R
+are for left and right field justification respectively.
+They are useful for aligning columns in a report.
+For each of these attributes, a width can be defined explicitly or else
+it is defined the first time an assignment is made to the variable.
+Each assignment causes justification of the field, truncating
+if necessary.
+Assignment to fixed sized variables
+provides one way to generate a substring consisting of
+a fixed number of characters from
+the beginning or end of a string.
+Other methods are discussed later.
+.P
+The attributes
+.B \-u
+and
+.B \-l
+are used for upper case and lower case
+formatting, respectively.
+Since it makes no sense to have both attributes on simultaneously,
+turning on either of these attributes turns the other off.
+The following script,
+using \f5read\fP and \f5print\fP which are described later,
+provides an example of the use of shell variables
+with attributes.
+This script reads a file of lines each consisting of five fields separated by
+.B :
+and prints fields 4 and 2 in upper case in columns 1-15, left justified,
+and columns 20-25 right-justified respectively.

+The
+.BR \-i ,
+.BR \-E ,
+and
+.BR \-F ,
+attributes are used to represent numbers.
+Each can be followed by a decimal number.
+The
+.B \-i
+attribute causes the value to be represented as an integer and it
+can be followed by a number representing the numeric base when expanding
+its value.
+Whenever a value is assigned to an integer variable, it is evaluated
+as an arithmetic expression
+and then truncated to an integer.
+.P
+The
+.B \-E
+attribute causes the value to be represented in scientific
+notation whenever its value is expanded.  The number following the 
+.B \-E
+determines the number of significant figures, and defaults to 6.
+The
+.B \-F
+attribute causes the value to be represented with a fixed number
+of places after the decimal point. 
+Assignments to variables with the
+.B \-E
+or
+.B \-F
+attributes cause the evaluation of the right hand side of the assignment.
+.P
+\f5ksh\fP allows one-dimensional
+.I arrays
+in addition to simple variables.
+There are two types of arrays; associative arrays
+and indexed arrays.
+The subscript for an associative array is an arbitrary
+string, whereas the subscript for an indexed array is
+an arithmetic expression that is evaluated to yield an integer
+index.
+Any variable can become an indexed array
+by referring to it with
+an integer
+.IR subscript .
+All elements of an array need not exist.
+Subscripts for arrays
+must evaluate to an
+integer between 0 and some maximum value, otherwise
+an error results.
+The maximum value may vary from one machine to another but
+is at least 4095.
+Evaluation of subscripts is described in
+the next section.
+Attributes apply to the whole array.
+.P
+Assignments to array variables can be made to individual elements
+via parameter
+assignment commands or the
+.B typeset
+built-in.
+Additionally, values can be assigned sequentially with
+compound assignment as described below, or by the
+.B \-A
+.I name
+option of the \f5set\fP command.
+Referencing of subscripted variables requires the character
+.BR $ ,
+but also requires braces around the array element name.
+The braces are needed to avoid conflicts with the
+file name generation mechanism.
+The form of any array element reference is:
+.ce
+.BI ${ name [ subscript ]}
+Subscript values of
+.B *
+and
+.B @
+can be used to generate all elements of an array,
+as they are used for expansion of positional parameters.
+The list of currently defined subscripts for a given
+variable can be generated with 
+.BI ${! name [@]} ,
+or
+.BI ${! name [*]} .
+.P
+The
+.B \-n
+or
+.I nameref
+attribute causes the variable to be treated
+as a reference to the variable defined by its value.
+Once this attribute is set, all references to this variable
+become references to the variable named by the value
+of this variable.
+For example, if \f5foo=bar\fP, then setting the reference
+attribute on \f5foo\fP will cause all subsequent references
+to \f5foo\fP to behave as the variable whose name is \f5$foo\fP
+was referenced, which in this case is the variable \f5bar\fP.
+Unsetting this attribute breaks the association.
+Reference variables are usually used inside functions whose
+arguments are the names of shell variables. 
+The names for reference variables cannot contain a \fB\s+2.\s-2\fP.
+Whenever a shell variable is referenced, the portion of the
+variable up to the first \fB\s+2.\s-2\fP
+is checked to see whether it matches the name of a reference
+variable.
+If it does, then the name of the variable actually used
+consists of the concatenation of the name of the variable
+defined by the reference plus the remaining portion of the
+original variable name.
+For example, using the predefined alias, \f5alias\ nameref='typeset\ -n'\fP,
+.sp
+.nf
+.in .5i
+.ta 3.4i
+\f5\^.bar.home.bam="hello world"
+nameref foo=.bar.home
+print ${foo.bam}
+\fBhello world\fP\fP
+.fi
+.ta
+.in
+.sp
+.H 2 "Compound Assignment"
+Compound assignments are used to assign values to arrays
+and compound data structures.
+The syntax for a compound assignment is
+.IB name =( assignment-list )
+where
+\fIname\fP
+is the name of the variable to which you want to assign values.
+No space is permitted between the variable name and the \fB=\fP
+but can appear between the \fB=\fP and the open parenthesis.
+New-lines can appear between the parentheses.
+.P
+The \fIassignment-list\fP can be in several different forms
+yielding different results.
+If \fIassignment-list\fP is simply a list of words, then
+the words are processed as they are with the \f5for\fP command
+and assigned sequentially as an indexed array.
+For example,
+.ce
+\f5foo=( * )\fP
+creates an indexed array \f5foo\fP and assigns the
+file names in the current directory to each index starting
+at zero.
+.P
+The second form for \fIassignment-list\fP is a list of assignments
+of the special form \fB[\fP\fIword\fP\fB]=\fP\fIword\fP.
+No space is permitted before or after the \fB=\fP.
+In this case, the variable given by \fIname\fP becomes
+an associative array with the given arguments as subscripts.
+For example,
+.ce
+\f5bar=( [color]=red [shape]=box )\fP
+creates an associate array named \f5bar\fP whose
+subscripts are \f5color\fP and \f5shape\fP.
+.P
+The third form for \fIassignment-list\fP is a list of
+normal assignments, including compound assignments.
+These assignments cause sub-variables to be assigned
+corresponding to the given assignments.
+In addition to assignments, the \fIassignment-list\fP
+can contain \f5typeset\fP commands.
+In addition to creating sub-variables,
+the effect of a compound assignment is to make
+the value of the original variable be a parenthesized
+assignment list of its components.
+For example, the assignment
+.sp
+.nf
+.in .5i
+.ta 3.4i
+\f5foo=(
+        left=bar
+        typeset -i count=3
+        point=(
+                x=50
+                y=60
+        )
+        colors=( red green yellow )
+        right=bam
+) \fP
+.ta
+.in
+.fi
+.sp
+is equivalent to the assignments
+.sp
+.nf
+.in .5i
+.ta 3.4i
+\f5foo.left=bar
+foo.count=3
+foo.point.x=50
+foo.point.y=60
+foo.colors=( red green yellow )
+foo.right=bam\fP
+.ta
+.in
+.fi
+.sp
+In addition, the value of \f5"$foo"\fP is
+.sp
+.nf
+.in .5i
+.ta 3.4i
+\f5(
+        colors=( red green yellow )
+        left=bar
+        typeset -i count=3
+        point=(
+                y=60

+.H 2 "Substring Generation"
+The expansion of a variable or parameter can be modified so that
+only a portion of the value results. 
+It is often necessary to extract a portion of a shell variable or
+a portion of an array.
+There are several parameter expansion operators that can do this.
+One method to generate a substring is with an expansion of
+the form \fB${\fP\fIname\fP\fB:\fP\fIoffset\fP\fB:\fP\fIlength\fP\fB}\fP
+where \fIoffset\^\fP is an arithmetic expression that defines the
+offset of the first character starting from 0, and
+\fIlength\^\fP is an arithmetic expression that defines the
+length of the substring.
+If
+.BI : length\^
+is omitted,
+the length of the value of
+.I name\^
+starting at
+.I offset\^
+is used.
+The
+.BI : offset : length
+operators can also be applied to array expansions and to parameters
+.B *
+and
+.B @
+to generate portions of an array.
+For example, the expansion, \fB${\fP\fIname\fP\fB[@]:\fP\fIoffset\fP\fB:\fP\fIlength\fP\fB}\fP, yields up to \fIlength\fP elements of the array \fIname\fP
+starting at the element \fIoffset\fP.
+.P
+The other parameter expansion modifiers use shell patterns
+to describe portions of the string to modify and delete.
+A description of shell patterns is contained below.
+When these
+modifiers are applied to special parameters
+.B @
+and
+.B *
+or to array parameters given as
+\fIname\fP\fB[@]\fP or \fIname\fP\fB[*]\fP,
+the operation is performed on each element.
+There are four parameter expansion modifiers that
+strip off leading and trailing substrings
+during parameter expansion
+by removing the characters matching a given pattern.
+An expansion of
+the form \fB${\fP\fIname\fP\fB#\fP\fIpattern\fP\fB}\fP
+causes the smallest matching prefix of the value of
+.I name\^
+to be removed.
+The largest prefix matching
+.I pattern\^
+is removed by using
+.B ##
+instead of
+.BR # .
+Similarly,
+an expansion of
+the form \fB${\fP\fIname\fP\fB%\fP\fIpattern\fP\fB}\fP
+causes the smallest matching substring at the end of
+.I name\^
+to be removed.
+Again, using
+.B %%
+instead of
+.BR % ,
+causes the largest matching trailing substring to be deleted.
+For example, if the shell variable
+.B file
+has value
+.BR foo.c ,
+then the expression
+.B ${file%.c}.o
+has value
+.BR foo.o .
+.P
+The value of an expansion can be changed by
+specifying a pattern that matches the part that needs to be changed
+after the
+the parameter expansion modifier
+.BR / .
+An expansion of the form
+\fB${\fP\fIname\fP\fB/\fP\fIpattern\fP\fB/\fP\fIstring\fP\fB}\fP
+replaces the first match of \fIpattern\fP with
+the value of variable \fIname\fP to \fIstring\fP.
+The second
+.B /
+is not necessary when \fIstring\fP is null.
+The expansion
+\fB${\fP\fIname\fP\fB//\fP\fIpattern\fP\fB/\fP\fIstring\fP\fB}\fP
+changes all occurrences of the \fIpattern\fP into \fIstring\fP.
+The parameter expansion modifiers
+.B /#
+and
+.B /%
+cause the matching pattern to be anchored to the beginning and
+end respectively.
+.P
+Finally, there are parameter expansion modifiers that yield
+the name of the variable, the string length of the value, or the number
+of elements of an array.
+\fB${!\fP\fIname\fP\fB}\fP
+yields the name of the variable which will be \fIname\fP itself
+except when \fIname\fP is a reference variable.  In this case
+it will yield the name of the variable it refers to.
+When applied to an array variable,
+\fB${!\fP\fIname\fP\fB[@]}\fP and
+\fB${!\fP\fIname\fP\fB[*]}\fP 
+generate the names of all subscripts.
+\fB${#\fP\fIname\fP\fB}\fP
+will be the length in bytes of
+\fB$\fP\fIname\fP.
+For an array variable
+\fB${#\fP\fIname\fP\fB[*]}\fP
+gives the number of elements in the array.
+.H 2 "Arithmetic Evaluation"
+.P
+For the most part, the shell is a string processing
+language.  However, the need for arithmetic has
+long been obvious.
+Many of the characters that are special to the
+Bourne shell are needed as arithmetic operators.
+To make arithmetic easy to use, and to maintain
+compatibility with the Bourne shell, \f5ksh\fP uses matching
+.B ((
+and
+.B ))
+to delineate arithmetic expressions.
+While single parentheses might have been
+more desirable, these already mean
+.I subshell\^
+so that another notation was required.
+The arithmetic expression
+inside the double parentheses
+follows the same syntax, associativity and precedence
+as the ANSI-C\*(Rf
+.RS
+American National Standard for Information Systems \- Programming
+Language \- C, ANSI X3.159-1989.
+.RF
+programming language.
+The characters between the matching double parentheses
+are processed with the same rules used for double
+quotes so that spaces can be used to aid readability
+without additional quoting.
+.P
+All arithmetic evaluations are performed using
+double precision floating point arithmetic.
+Floating point constants follow the same rules as
+the ANSI-C programming language.
+Integer arithmetic constants are written as
+.ce
+.IB base # number,
+where
+.I base\^
+is a decimal integer between
+two and sixty-four and
+.I number\^
+is any non-negative number.
+Base ten is used
+when no base is specified.
+The digits are represented by the characters
+.BR 0-9a-zA-Z_@ .
+For bases less than or equal to 36,
+upper and lower case characters can
+be used interchangeably to represent the digits
+from 10 thru 35.
+.P
+Arithmetic expressions are made from constants,
+variables, and operators.
+Parentheses may be used for grouping.
+The contents inside the double parentheses
+are processed with the same expansions as occurs in a double quoted string,
+so that all
+.B $
+expansions are performed before the expression is evaluated.
+However, there is usually no need to use the
+.B $
+to get the value of a variable
+because the arithmetic evaluator replaces the name of the variable
+by its value within an arithmetic expression.
+The
+.B $
+cannot be used when the variable is the subject of assignment
+or an increment operation.
+As a rule it is better not to use
+.B $
+in front of variables in an arithmetic expression.
+.P
+An arithmetic command of the form
+.B
+(( ... ))
+.R
+is a command that evaluates the enclosed arithmetic expression.
+For example, the command
+.ce
+\f5(( x++ ))\fP
+can be used to
+increment the variable \f5x\fP,
+assuming that \f5x\fP contains some numerical value.
+The arithmetic command is true (return value 0), when the resulting
+expression is non-zero, and false (return value 1) when the
+expression evaluates to zero.
+This makes the command easy to use with the \f5if\fP and \f5while\fP
+compound commands.
+.P
+The \f5for\fP compound command
+has been extended for use in arithmetic contexts. 
+The syntax,
+.ce
+\f5for\fP \fB((\fP \fIexpr1\fP\fB;\fP \fIexpr2\fP \fB;\fP \fIexpr3 \fP\fB))\fP
+can be used as the first line of a \f5for\fP loop with the same semantics
+as the \f5for\fP statement in the ANSI-C programming language.
+.P
+Arithmetic evaluations can also be performed as part of the evaluation
+of a command line.
+The syntax
+.B
+$((\ ...\ ))
+.R
+expands to the value of the enclosed arithmetic expression.
+This expansion can occur wherever parameter expansion is performed.
+For example using the \f5ksh\fP command \f5print\fP (described
+later)
+.ce
+\f5print $((2+2))\fP
+prints the number 4.
+.P
+The following script prints the first
+.I n
+lines of its standard input onto its standard output,
+where
+.I n
+can be supplied as an optional argument whose default value is 20.
+.sp
+.nf
+.in .5i
+.ta 4i
+\f5integer n=${1-20}                       # set n
+while   (( n-- >=0 )) && read -r line   # at most n lines
+do      print -r -- "$line"
+done\fP
+.fi
+.ta
+.in
+.sp
+.H 2 "Shell Expansions"
+.P
+The commands you enter from the terminal or from a script
+are divided into words and each word undergoes several
+expansions to generate the command name and its arguments.
+This is done in two phases.
+The first phase recognizes reserved words, spaces and operators
+to decide where command boundaries lie.
+Alias substitutions take place during this phase.
+The second phase performs expansions in the following order:
+.BL
+.LI
+Tilde substitution,
+parameter expansion,
+arithmetic expansion,
+and command substitution
+are performed from left to right.
+The option
+.B \-u
+or
+.BR nounset ,
+will cause an error to occur when any variable 
+that is not set is expanded. 
+.LI
+The characters that result from parameter expansion and
+command substitution above are checked with the characters
+in the
+\fB\s-1IFS\s+1\fP variable
+for possible
+field splitting.
+(See a description of \f5read\fP below to see how
+\fB\s-1IFS\s+1\fP is used.)
+Setting
+\fB\s-1IFS\s+1\fP to a null
+value causes field splitting to be skipped.
+.LI
+Pathname generation (as described below)
+is performed on each of the fields.
+Any field that doesn't match a pathname is left alone.
+The option,
+.B \-f
+or
+.BR noglob ,
+is used to disable pathname generation.
+.LE
+.H 2 "Pattern Matching"
+The shell is primarily a string processing language and uses
+patterns for matching file names as well as for matching strings.
+The characters
+.BR ? ,
+.BR * ,
+and
+.B [
+are processed specially 
+by the shell when not quoted.
+These characters are used to form patterns that
+match strings.
+Patterns are used by the shell to match pathnames,
+to specify substrings,
+and for
+.B case
+commands.
+The character
+.B ?
+matches any one character.
+The character
+.B *
+matches zero or more characters.
+The character sequence
+.BR [ ... ]
+defines a character class
+that matches any character contained within
+.BR [\^] .
+A range of characters can be specified by putting a
+.B \-
+between the first and last character of the range.
+An exclamation mark,
+.BR ! ,
+immediately after the
+.BR [ ,
+means match all characters except the characters specified.
+For example, the pattern
+\f5a?c*.[!a-z]\fP
+matches any string beginning with an
+.BR a ,
+whose third character is a
+.BR c ,
+and that ends in
+.B .
+(dot) followed by any character except the lower case letters,
+.BR a\-z .
+The sequence \f5[:alpha:]\fP
+inside a character class, matches any set of characters in
+the ANSI-C
+.B alpha
+class.
+Similarly, \f5[:\fP\fIclass\fP\f5:]\fP matches
+each of the characters in the given \fIclass\fP
+for all the ANSI-C character classes.
+For example, \f5[[:alnum:]_]\fP
+matches any alpha-numeric character or the character
+.BR _ .
+.P
+\f5ksh\fP
+treats
+strings of the form
+.BI ( pattern-list
+.BR ) ,
+where
+.I pattern-list
+is a list of one or more patterns separated by a
+.BR \(bv ,
+specially when preceded by
+.BR * ,
+.BR ? ,
+.BR + ,
+.BR @ ,
+or
+.BR ! .
+A
+.B ?
+preceding
+.BI ( pattern-list )
+means that the pattern list enclosed in
+.B (\^)
+is optional.
+An
+.BI @( pattern-list )
+matches any pattern in the list of patterns enclosed in
+.BR () .
+A
+.BI *( pattern-list )
+matches any string that contains zero or more of each of the enclosed
+patterns,
+whereas
+.BI +( pattern-list )
+requires a match of one or more of any of the given patterns.
+For instance, the pattern
+.B +([0\-9])?(.)
+matches one or more digits optionally followed by a
+.BR . (dot).
+A
+.BI !( pattern-list )
+matches anything except any of the given patterns.
+For example,
+\f5print\ !(*.o)\fP
+displays all file names in the current directory that do not end in
+.BR .o .
+.P
+When patterns are used to generate pathnames when expanding
+commands several other rules apply.
+A separate match is made
+for each file name component of the pathname. 
+Read permission is required for
+any portion of the pathname that contains any special
+pattern character. 
+Search permission is required for every component except
+possibly the last.
+.P
+By default,
+file names in each directory that begin with \fB\s+2.\s-2\fP
+are skipped when performing a match.
+If the pattern to be matched starts with a leading \fB\s+2.\s-2\fP,
+then only files beginning with a \fB\s+2.\s-2\fP,
+are examined when reading each directory to find matching files.
+If the
+\fB\s-1FIGNORE\s+1\fP variable
+is set,
+then only files that do not match this pattern
+are considered.
+This overrides the special meaning of \fB\s+2.\s-2\fP
+in a pattern and in a file name.
+.P
+If the
+.B markdirs
+option is set,
+each matching pathname that is the name
+of a directory has a trailing 
+.B /
+appended to the name.
+.P
+.H 2 "Conditional Expressions"
+The Bourne shell uses the \f5test\fP
+command, or the equivalent \f5[\fP
+command, to test files for attributes
+and to compare strings or numbers.
+The problem with \f5test\fP
+is that the shell has expanded the words of the \f5test\fP
+command and
+split them into arguments before \f5test\fP begins execution.
+\f5test\fP
+cannot distinguish between operators and operands.
+In most cases
+\f5test\ "$1"\fP
+will test whether argument 1 is non-null.
+However,
+if argument 1 is
+.BR \-f ,
+then \f5test\fP
+will treat
+.B \-f
+as an operator and
+yield a syntax error.
+One of the most frequent errors with
+\f5test\fP
+occurs when its operands are not within double quotes.
+In this case, the argument may expand to more than a single
+argument or to no argument at all.  In either case this
+will likely cause a syntax error.
+What makes this most insidious is that these errors are frequently
+data dependent.  A script that appears to run correctly may abort
+if given unexpected data.
+.P
+To get around these problems,
+\f5ksh\fP
+has a compound command for conditional expression testing
+as part of the language.
+The reserved words
+.B [[
+and
+.B ]]
+delimit the range of the command. 
+Because they are reserved words, not operator characters,
+they require spaces to separate them
+from arguments.
+The words between
+.B [[
+and
+.B ]]
+are not processed for field splitting or for pathname generation.
+In addition, since \f5ksh\fP
+determines the operators before parameter expansion,
+expansions that yield no argument cause no problem.
+The operators within
+.BR [[ ... ]]
+are almost the same as those for the \f5test\fP
+command.
+All unary operators are of the form
+.BI \- letter
+and are followed by a single operand.
+Instead of
+.B \-a
+and
+.BR \-o ,
+.BR [[ ... ]]
+uses
+.B &&
+and
+.B \(bv\(bv
+to indicate "and" and "or".
+Parentheses are used without quoting for grouping.
+.P
+The right hand side of the string comparison operators
+.B ==
+and
+.B !=
+takes a pattern and tests whether the left hand operand
+matches this pattern.  Quoting the pattern results
+is a string comparison rather than the pattern match. 
+The operators
+.B <
+and
+.B >
+within
+.BR [[ ... ]]
+designate lexicographical comparison.
+.P
+In addition there are several other new comparison primitives.
+The binary operators
+.B \-ot
+and
+.B \-nt
+compare the modification times
+of two files to see which file is
+.I "older than"
+or
+.I "newer than"
+the other.
+The binary operator
+.B \-ef
+tests whether two files
+have the same device and i-node number,
+i.\ e., a link to the same file.
+.P
+The unary operator
+.B \-L
+returns true if its operand is a symbolic link.
+The unary operator
+.B \-O
+(\fB\-G\fP)
+returns true if the owner (or group) of the file operand matches
+that of the caller.
+The unary operator
+.B \-o
+returns true when its operand is the name of an option that is
+currently on.
+.P
+The following script illustrates some of the uses of
+.BR [[ ... ]] . 
+The reference manual contains the complete list of operators.
+.sp
+.nf
+.in .5i
+.ta 4i
+\f5for i
+do      # execute foo for numeric directory
+        if      [[ \-d $i && $i == +([0\-9]) ]]

+done\fP
+.fi
+.ta
+.in
+.sp
+.H 2 "Input and Output"
+\f5ksh\fP has
+extended I/O capabilities to enhance the
+use of the shell as a programming language.
+As with the Bourne shell,
+you use the I/O redirection operator,
+.BR < ,
+to control where input comes from,
+and the I/O redirection operator,
+.BR > ,
+to control where output goes to. 
+Each of these operators can be preceded with a single digit that
+specifies a file unit number to associate with the file stream.
+Ordinarily you specify these I/O redirection operators with a specific
+command to which it applies.
+However, if you specify I/O redirections with the \f5exec\fP
+command,
+and don't specify arguments to \f5exec\fP,
+then the I/O redirection applies to the current program.
+For example, the command
+\f5exec\ <\ foobar\fP
+opens file \f5foobar\fP
+for reading.
+The \f5exec\fP
+command is also used to close files.
+A file descriptor unit can be opened as a copy of an existing
+file descriptor unit by using either of the
+.B <&
+or
+.B >&
+operators and putting the file descriptor unit of the original file
+after the
+.BR & .
+Thus, \f52>&1\fP means open standard error (file descriptor 2)
+as a copy of standard output (file descriptor 1).
+A file descriptor value of
+.B \-
+after the
+.B &
+indicates that the file should be closed.
+To close file unit 5, specify
+\f5exec\ 5<&-\fP.
+There are two additional redirection operators with \f5ksh\fP
+and the POSIX shell that are not part of the Bourne shell.
+The
+.B >|
+operator overrides the effect of the
+.B noclobber
+option described earlier.
+The
+.B <\^>
+operator causes a file to be opened for both reading and writing.
+.P
+\f5ksh\fP recognizes certain pathnames and treats them
+specially.
+Pathnames of the form
+.BI /dev/fd/ n\^
+are treated as equivalent to the file defined by file descriptor
+.IR n .
+These name can be used as the script argument to \f5ksh\fP
+and in conditional testing as described above.
+On underlying systems that support
+.B /dev/fd
+in the file system, these names can be passed to other commands.
+Pathnames of the form
+.BI /dev/tcp/ hostid / port
+and
+.BI /dev/udp/ hostid / port
+can be used to create
+.B tcp
+and
+.B udp
+connections to services given by the
+.I hostid\^
+number and
+.I port\^
+number.
+The
+.I hostid\^
+cannot use symbolic values. In practice these
+numbers are typically generated by command substitution.
+For example,
+\f5exec\ 5>\ /dev/tcp/$(service\ name)\fP
+would open file descriptor 5 for sending messages
+to hostid and port number defined by the output of \f5service\ name\fP.
+.P
+The Bourne shell has a built-in command \f5read\fP
+for reading lines from standard input (file descriptor 0)
+and splitting it into fields based on the value of the
+.B \s-1IFS\s+1
+variable, and a command \f5echo\fP
+to write strings to standard output.
+(On some systems, \f5echo\fP
+is not a built-in command and incurs considerable overhead to use.)
+Unfortunately, neither of these commands
+is able to perform some very basic tasks.
+For example.
+with the Bourne shell,
+the \f5read\fP
+built-in cannot read a single line that ends in
+.BR \e .
+With \f5ksh\fP
+the \f5read\fP
+built-in has a
+.B \-r
+option to remove the special meaning for
+.B \e
+which allows it to be
+treated as a regular
+character rather than the line continuation character.
+With the Bourne shell,
+there is no simple way to have more than one file open
+at any time for reading.
+\f5ksh\fP has options on the \f5read\fP
+command to specify the file
+descriptor for the input.
+The fields that are read from a line can be stored into an indexed
+array with the
+.B \-A
+option to read.
+This allows a line to be split into an arbitrary number of fields.
+.P
+The way the Bourne shell uses the
+\fB\s-1IFS\s+1\fP variable to
+split lines into fields greatly limits its utility.
+Often data files consist of lines that use a character such
+as
+.B :
+to delimit fields with two adjacent delimiters that denote
+a null field.
+The Bourne shell treats adjacent delimiters as a single
+field delimiter.
+With \f5ksh\fP,
+delimiters that are considered white space characters
+have the behavior of the Bourne shell, but other
+adjacent delimiters separate
+null fields.
+.P
+The \f5read\fP command is often used in scripts that interact
+with the user by prompting the user and then requesting some
+input.
+With the Bourne shell two commands are needed; one to
+prompt the user, the other to read the reply.
+\f5ksh\fP allows these two commands to be combined.
+The first argument of the \f5read\fP
+command can be followed by a
+.B ?
+and a prompt string which is used whenever the input
+device is a terminal.
+Because the prompt is associated with the \f5read\fP built-in,
+the built-in command line editors will be able to re-output
+the prompt whenever the line needs to be refreshed when
+reading from a terminal device.
+.P
+With the Bourne shell,
+there is no way to set a time limit for waiting for the user
+response to read.
+The
+.B \-t
+option to \f5read\fP takes a floating
+point argument that gives the time in seconds,
+or fractions of seconds that the shell should wait for a reply.
+.P
+The version of the \f5echo\fP command in System V
+treats certain sequences beginning with
+.B \e
+as control sequences.
+This makes it hard to output strings without interpretation.
+Most BSD derived systems do not interpret
+.B \e
+control sequences.
+Unfortunately, the BSD versions of \f5echo\fP accepts a 
+.B \-n
+option to prevent a trailing new-line, but has no way to
+cause the string
+.B \-n
+to be printed.
+Neither of these versions is adequate. Also, because they
+are incompatible, it is very hard to write portable shell scripts
+using \f5echo\fP.
+The \f5ksh\fP built-in, \f5print\fP,
+outputs characters to the terminal or to a file and
+subsumes the functions of all versions of \f5echo\fP.
+Ordinarily, escape sequences in arguments beginning with
+.B \e
+are processed the same as for the System V \f5echo\fP command.
+However \f5print\fP follows the standard conventions for
+options and has options that make \f5print\fP very versatile.
+The
+.B \-r
+option can be used to output the arguments without any special meaning.
+The
+.B \-n
+option can be used here to suppress the trailing new-line
+that is ordinarily appended.
+As with \f5read\fP, it is possible to specify the file descriptor number
+as an option to the command to avoid having to use
+redirection operators with each occurrence of the command.
+.P
+The IEEE POSIX shell and utilities standard committee was unable
+to reconcile the differences between the System V and BSD
+versions of \f5echo\fP.
+They introduced a new command named \f5printf\fP
+which takes an ANSI-C format string and a list of options
+and outputs the strings using the ANSI-C formatting rules.
+Since \f5ksh\fP is POSIX conforming, it accepts \f5printf\fP.
+However, there is a
+.B \-f
+options to \f5print\fP that can be used to specify
+a format string which processes the arguments the same way that
+\f5printf\fP does.
+.P
+The format processing for \f5print\fP and \f5printf\fP has
+been extended slightly.
+There are three additional formatting directives.
+The
+.B %b
+format causes the
+.B \e
+escape sequences to be expanded as they are with the System V \f5echo\fP
+command.
+The
+.B %q
+format causes quotes to
+be placed on the output as required
+so that it can be used as shell input.
+Special characters in the output of most \f5ksh\fP built-in commands
+and in the output from an execution trace
+are quoted in an equivalent fashion. 
+The
+.B %P
+format causes an extended regular expression string to
+be converted into a shell pattern.
+This is useful for writing shell applications that have
+to accept regular expressions as input.
+Finally, the escape sequence
+.B \e\^E
+which expands to the terminal escape character (octal 033)
+has been added.
+.P
+The shell is frequently used as a programming language for
+interactive dialogues.
+The
+\f5select\fP
+statement has been added to the language
+to make it easier to
+present menu selection alternatives to the
+user and evaluate the reply.
+The list of alternatives is numbered and put in columns.
+A user settable prompt,
+\fB\s-1PS3\s+1\fP,
+is issued and if the answer is
+a number corresponding to one of the alternatives,
+the select loop variable is set to this value.
+In any case, the
+.B \s-1REPLY\s+1
+variable is used to store the user entered reply.
+The shell variables
+.B \s-1LINES\s+1
+and
+.B \s-1COLUMNS\s+1
+are used to control the layout of select lists.
+.H 2 "Option Parsing"
+The \f5getopts\fP built-in command can be used
+to process command arguments in a manner consistent
+with the way \f5ksh\fP does for its own built-in commands.
+.P
+The \f5getopts\fP built-in allows users to specify options
+as separate arguments or to group options that do not
+take arguments together.  Options that require arguments
+do not require space to separate them from the option argument.
+The
+.B \s-1OPTARG\s+1
+variable stores the value of the option argument
+after finding a variable that takes an argument.
+The
+.B \s-1OPTIND\s+1
+variable holds the index of the current options argument.
+After processing options, the arguments should be
+shifted by
+.B \s-1OPTIND\s+1\-1
+to make the
+remaining arguments be \f5"$@"\fP.
+.P
+The \f5getopts\fP argument description allows additional
+information to be specified along with the options
+that is used to generate \fIusage\fP messages for
+incorrect arguments and for the option argument \fB\-?\fP.
+The example in the APPENDIX uses \f5getopts\fP to process
+its arguments.
+.H 2 "Co-process"
+\f5ksh\fP can spawn a
+.I co-process
+by adding a
+.B "|&"
+after a command.
+This process will be run with its standard input and its
+standard output connected to the shell.  The built-in command \f5print\fP
+with the
+.B \-p
+option will write into the standard input of this
+process and
+the built-in command \f5read\fP
+with the
+.B \-p
+option will read from the output of this process.
+.P
+In addition, the I/O redirection operators \fB<&\fP and \fB>&\fP can
+be used to move the input or output pipe of the co-process
+to a numbered file descriptor.
+Use \f5exec\ 3>&\ p\fP to move the input of the co-process
+to file descriptor \fB3\fP.
+After you have connected to file descriptor \fB3\fP, you
+can direct the output of any command to the co-process
+by running \fIcommand\fP\f5\ >&3\fP.
+Also, by moving the input of the co-process to a numbered descriptor,
+it is possible to run a second co-process.
+The output of both co-processes will be the file descriptor
+associated with \f5read\ -p\fP.
+You can use \f5exec\ 4<&\ p\fP to cause the output of these
+co-processes to go to file descriptor \fB4\fP of the shell.
+Once you have moved the pipe to descriptor \fB4\fP, it is possible
+to connect a server to the co-process by running \fIcommand\fP\f5\ 4<&\ p\fP
+or to close the co-process pipe with \f5exec\ 4<&\ -\fP.
+.H 2 "Functions"
+.P
+Function definitions are of the form
+.sp
+.in +.5i
+.nf
+\f5function\fP \fIname\fP
+.br
+.B {
+.br
+        any shell script
+.br
+.B }
+.fi
+.sp
+.in
+A function whose name contains a \fB\s+2.\s-2\fP
+is called a \fIdiscipline\fP function.
+The portion of the name after the last \fB\s+2.\s-2\fP
+is the name of the discipline.
+Discipline functions named \f5get\fP, \f5set\fP, and \f5unset\fP
+can be assigned to any variable to intercept lookups,
+assignments and unsetting of the variable
+defined by the portion of the name before the last \fB\s+2.\s-2\fP.
+Applications can create additional disciplines for variables
+that are created as part of user defined built-ins.
+The portion of the name before the last \fB\s+2.\s-2\fP
+must refer to the name of an existing variable.
+Thus, if \f5p\fP is a reference to \f5PATH\fP, then
+the function name \f5p.get\fP and \f5PATH.get\fP
+refer to the same function.
+.P
+The function is invoked either
+by specifying
+.I name
+as the command name
+and optionally following it with arguments
+or by using it as an option to the \fB\s+2.\s-2\fP
+built-in command.
+Positional parameters are saved before each
+function call and restored when completed.
+The arguments that follow the function name on the calling
+line become positional parameters inside the function.
+The \f5return\fP
+built-in can be used to cause the function to return to
+the statement following
+the point of invocation.
+.P
+Functions can also be defined with the System V notation,
+.sp
+.in +.5i
+.nf
+\fIname\fP \f5()\fP
+.br
+.B {
+.br
+        any shell script
+.br
+.B }
+.fi
+.sp
+.in
+Functions defined with this syntax cannot be used as the first
+argument to a \fB\s+2.\s-2\fP procedure.
+\f5ksh\fP accepts this notation for compatibility only.
+There is no need to use this notation when writing
+\f5ksh\fP scripts.
+.P
+Functions defined with the \f5function\fP\ \fIname\fP syntax
+and invoked by name
+are executed in the current shell environment
+and can share named variables with the calling program.
+Options, other than execution trace
+.BR \-x ,
+set by the calling program are
+passed down to a function.
+The options are
+not shared with
+the function so that any options set within a function are
+restored when the function exits.
+Traps ignored by the caller are ignored within the function
+and cannot be enabled.
+Traps caught by the calling program are reset to their
+default action within the function.
+In most instances, the default action is
+to cause the function to terminate.
+A trap on
+\fB\s-1EXIT\s+1\fP
+defined within a function executes after the function
+completes but
+before the caller resumes.
+Therefore,
+any variable assignments and
+any options set as part of a trap action will be effective
+after the caller resumes.
+.P
+By default, variables are inherited by the function and shared
+by the calling program.
+However,
+for functions defined with the \f5function\fP\ \fIname\fP syntax
+that are invoked by name,
+environment substitutions preceding the function call
+apply only to the scope of the function call.
+Also, variables whose names do not contain a \fB\s+2.\s-2\fP
+that are defined with the \f5typeset\fP
+built-in command are local to the function that they are declared in.
+Thus, for the function defined
+.sp
+.nf
+.in .5i
+\f5function  name
+{
+     typeset -i x=10
+     let z=x+y
+     print $z
+}\fP
+.fi
+.ta
+.in
+.sp
+invoked as
+\f5y=13\ name\fP,
+\f5x\fP and \f5y\fP
+are local variables with respect to the function
+\f5name\fP
+while
+\f5z\fP
+is global.
+.P
+Functions defined with the \fIname\fP\f5()\fP syntax,
+and functions invoked as an argument to the \fB\s+2.\s-2\fP
+command,
+share everything other than positional parameters with the caller.
+Assignments that precede the call remain in effect after the
+function completes.
+.P
+Alias and function names are not passed down to shell scripts
+or carried across separate
+invocations of \f5ksh\fP.
+The
+.B $\s-1FPATH\s+1
+variable gives a colon separated list of directories that
+is searched for function definitions when trying to resolve
+the command name.
+Whenever a file name contained in
+.B $\s-1FPATH\s+1
+is found, the complete file is read and all functions
+contained within become defined.
+.P
+Calls that reference functions can be recursive.
+Except for special built-ins,
+function names take precedence over built-in names and names
+of programs when used as command names.
+To write a replacement function that invokes the command that
+you wish to replace,
+you can use the \f5command\fP built-in command.
+The arguments to \f5command\fP are the name and arguments
+of the program you want to execute.
+For example to write a
+.B cd
+function which changes the directory and prints out the directory name,
+you can write
+.sp
+.nf
+.in .5i
+\f5function  cd
+{
+     if      command cd  "$@"
+     then    print  -r -- $PWD
+     fi
+}\fP
+.fi
+.ta
+.in
+.sp
+.P
+The
+\fB\s-1FPATH\s+1\fP
+variable is a colon separated list that \f5ksh\fP
+uses to search for function definitions.
+When
+\f5ksh\fP
+encounters an autoload function,
+it runs the
+.B .
+command on the script containing the function,
+and then executes the function.
+.P
+For interactive shells,
+function definitions may also be placed in the
+\fB\s-1ENV\s+1\fP
+file.
+However, this
+causes the shell to take longer to begin executing.
+.H 2 "Process Substitution"
+.P
+This feature is only available
+on versions of the UNIX operating system which support the
+.B /dev/fd
+directory for naming open files.
+Each command argument of the form
+\fB<(\fP\fIlist\^\fP\fB)\fP
+or
+\fB>(\fP\fIlist\^\fP\fB)\fP
+will run process
+.I list
+asynchronously connected to some file in the
+.B /dev/fd
+directory.
+The name of this file will become the argument to the command.
+If the form with
+.B >
+is selected then writing on this file will provide input for
+.IR list .
+If
+.B <
+is used,
+then the file passed as an argument will contain the output of the
+.I list
+process.
+For example,
+.sp
+.nf
+.in .5i
+\f5paste  <(cut \-f1 \fP\fIfile1\fP\f5)  <(cut \-f2 \fP\fIfile2\fP\f5) | tee >(\fP\fIprocess1\fP\f5)  >(\fP\fIprocess2\fP\f5)\fP
+.fi
+.ta
+.in
+.sp
+extracts
+fields 1 and 3 from
+the files
+.I file1
+and
+.I file2
+respectively,
+places the
+results side by side, and
+sends it
+to the processes
+.I process1
+and
+.IR process2 ,
+as well as putting it onto the standard output.
+Note that the file which is passed as an argument to the command is
+a UNIX system
+.IR pipe (2)
+so that the programs that expect to
+.IR lseek (2)
+on the file will not work.
+.H 2 "Finding Commands"
+.P
+The addition of aliases, functions,
+and more built-ins
+has made it substantially more difficult to know what
+a given command name really means.
+.P
+Commands that begin with reserved words
+are an integral part of the shell language itself
+and typically define the control flow of the language.
+Some control flow commands are not reserved words in
+the language but are \fIspecial\fP built-ins.
+Special built-ins are built-ins that are considered a
+part of the language rather than user definable commands.
+The best examples of commands that fit this description
+are \f5break\fP and \f5continue\fP.
+Because they are not reserved words, they can be the
+result of shell expansions and are not effected by quoting. 
+These commands have the following special properties:
+.BL
+.LI
+Assignments that precede them apply to the current shell process,
+not just to the given command.
+.LI
+An error in the format of these commands cause a shell script
+or function that contains them to abort.
+.LI
+They cannot be overridden by shell functions.
+.LE
+.P
+Other commands are built-in because they perform side effects
+on the current environment that would be nearly impossible
+to implement otherwise.
+Built-ins such as \f5cd\fP and \f5read\fP
+are examples of such built-ins.
+These built-ins are semantically equivalent to commands that
+are not built-in except that they don't take a path search
+to locate.
+.P
+A third reason to have a command built-in is so that
+it will be unaffected by the setting of the
+.B \s-1PATH\s+1
+variable.
+The \f5print\fP  command fits this category.
+Scripts that use \f5print\fP will be portable
+to all sites that run \f5ksh\fP.
+.P
+The final reason for having a command be a built-in is
+for performance.
+On most systems it is more than an order of magnitude
+faster to initiate a command that is built-in than
+to create a separate process to run the command.
+Examples that fit this category are \f5test\fP
+and \f5pwd\fP.
+.P
+Given a command name \f5ksh\fP decides what it means using
+the following order:
+.BL
+.LI
+Reserved words define commands that form part of the shell
+grammar.
+They cannot be quoted.
+.LI
+Alias substitutions occur first as part of the reading of commands.
+Using quotes in the command name will prevent alias substitutions.
+.LI
+Special built-ins.
+.LI
+Functions.
+.LI
+Commands that are built-in that are not associated with a pathname
+such as \f5cd\fP and \f5print\fP.
+.LI
+If the command name contains a
+.BR / ,
+the program or script corresponding to the given name is executed.
+.LI
+A path search locates the pathname corresponding to the command.
+If the pathname where it is found matches the pathname associated
+with a built-in command, the built-in command is executed.
+If the directory where the command is found is listed in the
+.B \s-1FPATH\s+1
+variable, the file is read into the shell
+like a dot script, and a function by that name is invoked.
+Once a pathname is found, \f5ksh\fP remembers its location
+and only checks relative directories in \fB\s-1PATH\s+1\fP
+the next time the command name is used.
+Assigning a value to \fB\s-1PATH\s+1\fP
+causes \f5ksh\fP to forget the location of all command names.
+.LI
+The
+.B \s-1FPATH\s+1
+variable is searched and files found are treated as described above.
+.LE
+.P
+The first argument of the \f5command\fP built-in, described earlier,
+skips the checks for reserved words and for function definitions.
+In all other ways, \f5command\fP behaves like a built-in
+that is not associated with a pathname.
+As a result, if the first argument of \f5command\fP is
+a special built-in, the special properties of this built-in
+do not apply.  
+For example, whereas, \f5exec\ 3<\ foo\fP will cause a script containing
+it to abort if the open fails, \f5command\ exec\ 3<\ foo\fP
+results in a non-zero exit status but does not abort the script.
+.P
+You can get a complete list of the special built-in commands
+with \f5builtin\ -s\fP. 
+In addition \f5builtin\fP without arguments gives a list of
+the current built-ins and the pathname that they are associated with.
+A built-in can be bound to another pathname by giving
+the pathname for the built-in.  The basename of this path must
+be the name of an existing built-in for this to succeed.
+Specifying the name of the built-in without a pathname causes
+this built-in to be found before a path search.
+A built-in can be deleted  with the \fB\-d\fP option.
+.P
+On systems with run time loading of libraries, built-in commands
+can be added with the \f5builtin\fP command.
+Each command that is to be built-in must be written as a
+C function whose name is of the form \f5b_\fP\fIname\fP, where
+\fIname\fP is the name of the built-in that is to be added.
+The function has the same argument calling convention as
+\f5main\fP.  The lower eight bits of the return value become
+the exit status for this built-in.
+Builtins are added by specifying the pathname of the library
+as an argument to the \fB\-f\fP option of \f5builtin\fP.
+.P
+The built-in command,
+\f5whence\fP,
+when used with the
+.B \-v
+option, tells how a given command is bound.
+A line is printed for each argument to \f5whence\fP
+telling what would happen if this argument were used as a command name.
+It reports on reserved words, aliases, built-ins, and
+functions.
+If the command is none of the above,
+it follows the path search rules and prints the full path-name,
+if any, otherwise it prints an error message.
+.H 2 "Symbolic Names"
+To avoid implementation dependencies, \f5ksh\fP
+accepts and generates symbolic names
+for built-ins that use numerical values in the Bourne shell.
+The
+.B \-S
+option of the
+\f5umask\fP built-in command
+accepts and displays
+default file creation permissions
+symbolically.
+It uses the same symbolic notation as the \f5chmod\fP command.
+.P
+The \f5trap\fP and \f5kill\fP built-in commands
+allows the signal names to be given symbolically.
+The names of signals and traps
+corresponding to signals are the same as the signal name with
+the
+.B \s-1SIG\s+1
+prefix removed.
+The trap
+.B 0
+is named
+\fB\s-1EXIT\s+1\fP.
+.H 2 "Additional Variables"
+In addition to the variables discussed earlier, \f5ksh\fP
+has other variables that it handles specially. 
+The variable \fB\s-1RANDOM\s+1\fP
+produces a random number in the range 0 to 32767 each time it is referenced.
+Assignment to this variable sets the seed for the
+random number generator.
+.P
+The parameter \fB\s-1PPID\s+1\fP
+is used to generate the process id of the process which invoked this shell.
+.H 2 "Added Traps"
+A new trap named
+\fB\s-1ERR\s+1\fP
+has been added.
+This trap is invoked whenever the shell would exit if the
+.B \-e
+option were set.
+This trap is used by
+Fourth Generation Make\*(Rf
+.RS
+G. S. Fowler,
+.I "The Fourth Generation Make,"
+Proceedings of the Portland USENIX meeting, pp. 159-174, 1985.
+.RF
+which runs \f5ksh\fP
+as a co-process.
+.P
+A trap named
+\fB\s-1DEBUG\s+1\fP
+gets executed after each command.
+This trap can be used for debugging and other purposes.
+.P
+The
+\fB\s-1KEYBD\s+1\fP
+trap was described earlier.
+.H 2 Debugging
+The primary method for debugging Bourne shell scripts is to
+use the
+.B \-x
+option to enable the execution trace.
+After all
+the expansions have been performed,
+but before each command is executed,
+the trace writes to standard error the name and arguments
+of each command preceded by a
+.BR + .
+While the trace is very useful, there is no way
+to find out what line of source a given trace line
+corresponds to.
+With
+\f5ksh\fP
+the
+\fB\s-1PS4\s+1\fP
+variable
+is evaluated for parameter expansion and
+is displayed before each command,
+instead of the
+.BR + .
+.P
+The

+.H 2 "Timing Commands"
+.P
+Finding the time it takes to execute commands
+has been a serious problem with the Bourne shell.
+Since the \f5time\fP command is not part of the
+language, it is necessary to write a script
+in order to time a \f5for\fP or \f5while\fP loop.
+The extra time in invoking the shell and processing
+the script is accumulated along with the time
+to execute the script.
+.P
+More seriously, the Bourne shell does not give correct
+times for pipelines.
+The reason for this is that the times for some members
+of a pipeline are not counted when computing the time.
+As an extreme example,
+running \f5time\fP on the script
+.ce
+\f5cat < /dev/null | sort -u bigfile | wc\fP
+with the Bourne shell will show very little
+user and system time no matter how
+large \f5bigfile\fP is.
+.P
+To correct these problems,
+a reserved word \f5time\fP
+has been added to replace
+the \f5time\fP
+command.
+Any function, command or pipeline can be preceded by this reserved word
+to obtain information about the elapsed, user, and system times.
+Since I/O redirections bind to the command, not to
+\f5time\fP,
+parentheses should be used to redirect the timing information which
+is normally printed on file descriptor 2.
+.H 1 SECURITY
+There are several documented problems associated with the security of
+shell procedures\*(Rf.
+.RS
+F. T. Grampp and R. H. Morris,
+.I "UNIX Operating System Security,"
+AT&T Bell Labs Tech. Journal, Vol. 63, No. 8, Part 2, pp. 1649-1671, 1984.
+.RF
+These security holes occur primarily because a user can manipulate the
+.I environment
+to subvert the intent of a
+.I setuid
+shell procedure.
+Sometimes, shell procedures are initiated from 
+binary programs, without the author's
+awareness, by library routines which invoke shells to carry out
+their tasks.
+When the binary program is run
+.I setuid
+then the shell procedure runs with the permissions afforded to the
+owner of the binary file.
+.P
+In the Bourne shell,
+the
+.B \s-1IFS\s+1
+parameter is used to split each word into separate command arguments.
+If a user knows that some
+.I setuid
+program will run
+\f5sh\ -c\ /bin/pwd\fP
+(or any other command in
+.BR /bin )
+then the user sets and exports
+.BR \s-1IFS\s+1=\^/ .
+Instead of running
+.B /bin/pwd
+the shell will run
+.B bin
+with
+.B pwd
+as an argument.
+The user puts his or her own \f5bin\fP
+program into the current directory.
+This program can
+create a copy of the shell,
+make this shell
+.IR setuid ,
+and then run the \f5/bin/pwd\fP
+program so that the original program continues to run successfully.
+This kind of penetration is not possible with
+\f5ksh\fP
+since the
+.B \s-1IFS\s+1
+parameter only splits arguments that result from command or parameter
+substitution.
+.P
+Some
+.I setuid
+programs run programs using
+.I system()
+without giving the full pathname.
+If the
+user sets the
+.B \s-1PATH\s+1
+variable so that the desired command will be found
+in his or her local bin, then the same technique described above can
+be employed to compromise the security of the system.
+To close up this and other security holes,
+\f5ksh\fP
+resets the effective user id to the real user id and the effective 
+group id to the real group id unless the
+.I privileged
+option
+.RB ( \-p\^ )
+is specified at invocation.
+In
+this mode, the
+.B privileged
+mode, the
+.B .profile
+and
+.B \s-1ENV\s+1
+files are not processed.
+Instead, the file
+.B /etc/suid_profile
+is read and executed.
+This gives an administrator control over the
+environment to set the
+.B \s-1PATH\s+1
+variable or to log setuid shell invocations.
+Clearly security of the system is compromised if
+.B /etc
+or this file is publicly writable.
+.P
+Some versions of the UNIX operating system look for the characters
+\f5#!\fP
+as the first two characters of an executable file.
+If these characters are found, then the next word on this line is taken
+as the interpreter to
+invoke
+for this command and the interpreter is
+.IR exec ed
+with the name of the script as argument zero and argument one.
+If the
+.I setuid
+or
+.I setgid
+bits are on for this file, then the interpreter
+is run with the effective uid and/or gid set accordingly.
+This scheme has three major drawbacks.
+First of all,
+putting the pathname of the interpreter into the script
+makes the script less portable since the interpreter
+may be installed in a different directory on another system.
+Secondly, using the
+\f5#!\fP
+notation forces an
+.B exec
+of the interpreter even when the call is invoked from the interpreter
+which it must exec.  This is inefficient since
+\f5ksh\fP can handle a failed exec much faster than starting up
+again.
+More importantly,
+.I setuid
+and
+.I setgid
+procedures provide an easy target for intrusion.
+By linking a
+.I setuid
+or
+.I setgid
+procedure to a name beginning with a
+.B \-
+the interpreter is fooled into thinking that it is being invoked with
+a command line option rather than the name of a file.
+When the interpreter is the shell, the user gets a privileged
+interactive shell.
+There is code in
+\f5ksh\fP
+to guard against this simple form of intrusion.
+.P
+A more reliable way to handle
+.I setuid
+and
+.I setgid
+procedures is provided with
+\f5ksh\fP.
+The technique does not require any changes to the operating system
+and provides better security.
+Another advantage to this method is that it also allows scripts which
+have execute permission but no read permission to run.  Taking away read
+permission makes scripts more secure.
+.P
+The method relies on a setuid
+.B root
+program to authenticate the
+request and exec the shell with the correct mode bits to carry out
+the task.  This shell is invoked with the requested file already open
+for reading.  A script which cannot be opened for reading or which
+has its setuid and/or setgid bits turned on causes this setuid
+.B root
+program to get \fBexec\fPed.
+For security reasons, this program is given the full
+pathname
+\f5/etc/suid_exec\fP.
+A description of the implementation of the
+\f5/etc/suid_exec\fP
+program can be found in
+a separate paper\*(Rf.

+TM-59554-860602-03, 1986.
+.RF
+.H 1 "CODE CHANGES"
+\f5ksh\fP is written in ANSI-C as a reusable library.
+The code can be compiled with C++ and older K&R C as well.
+The code uses the IEEE POSIX 1003.1 and ISO 9945-1 standard\*(Rf
+.RS
+.I "POSIX \- Part 1: System Application Program Interface,"
+IEEE Std 1003.1-1990, ISO/IEC 9945-1:1990.
+.RF
+wherever possible so that \f5ksh\fP should be able to run
+on any POSIX compliant system.  In addition, it is possible
+to compile \f5ksh\fP for older systems.
+.P
+Unlike earlier version of the Bourne shell,
+\f5ksh\fP treats eight bit characters transparently
+without stripping off the
+leading bit.
+There is also a compile time switch to enable handling multi-byte
+and multi-width characters sets.
+.P
+On systems with dynamic libraries, it is possible to add built-in
+commands at run time  with the built-in command \f5builtin\fP 
+described earlier.
+It is also possible to embed \f5ksh\fP in applications in
+a manner analogous to \f5tcl\fP.
+.H 1 "EXAMPLE"
+.P
+An example of a \f5ksh\fP script is included
+in the Appendix.
+This one page program is a variant of the UNIX system
+\f5grep\fP(1) program.
+Pattern matching for this version of \f5grep\fP
+means shell patterns.
+.P
+The first half uses the \f5getopts\fP command to
+find the option flags.
+Nearly all options have been implemented.
+The second half goes through each line of each file
+to look for a pattern match.
+.P
+This program is not intended to serve as a
+replacement for \f5grep\fP
+which has been highly tuned for performance.
+It does
+illustrate the programming power of \f5ksh\fP.
+Note that no auxiliary processes are spawned by this script.
+It was written and debugged in under two hours.
+While performance is acceptable for small files,
+this program runs at only one tenth
+the speed of \f5grep\fP
+for large files.
+.H 1 "PERFORMANCE"
+.P
+\f5ksh\fP executes many scripts faster than the System V Bourne shell;
+in some cases more than 10 times as fast.
+The primary reason for this is that \f5ksh\fP creates fewer
+processes.
+The time to execute a built-in command or a function is one or two
+orders of magnitude faster than performing a \f5fork\fP() and
+\f5exec\fP() to create a separate process.
+Command substitution and commands inside parentheses
+are performed without creating another process, unless necessary
+to preserve correct behavior.
+.P
+Another reason for improved performance is the use of the \fBsfio\fP\*(Rf,
+.RS
+David Korn and Kiem-Phong Vo,
+.IR "SFIO - A Safe/Fast String/File I/O,"
+Proceedings of the Summer Usenix,
+pp. 235-255, 1991.
+.RF
+library for I/O.  The \fBsfio\fP library buffers all I/O
+and buffers are flushed only when required.
+The algorithms used in \fBsfio\fP perform better than
+traditional versions of standard I/O so that programs that
+spend most of their time
+formatting output may actually perform better
+than versions written in C.
+.P
+Several of the internal algorithms have been changed
+so that the number of subroutine calls has been
+substantially reduced.
+\f5ksh\fP uses variable sized hash tables for variables.
+Scripts that rely heavily on referencing variables execute faster.
+More processing is performed while reading the script
+so that execution time is saved while running loops.
+These changes are not noticeable for scripts that \f5fork()\fP
+and run processes,
+but they reduce the time that it takes to interpret commands by
+more than a factor of two.
+.P
+Most importantly, \f5ksh\fP provide mechanisms to write applications
+that do not require as many processes.
+The arithmetic provided by the shell eliminates the need for the
+\f5expr\fP command.
+The pattern matching and substring capabilities eliminate the
+need to use \f5sed\fP or \f5awk\fP to process strings.
+.P
+The architecture of \f5ksh\fP makes it easy to make commands
+built-ins without changing the semantics at all.
+Systems that have run-time binding of libraries allow
+applications to be sped up by supplying the critical
+programs as shell built-in commands.
+Implementations on other systems can add built-in commands
+at compile time.
+The procedure for writing built-in commands that can be loaded
+at run time is in a separate document.\*(Rf,
+.RS
+David Korn,
+.IR "Guidelines for writing \f5ksh-93\fP built-in commands,"
+to be published, 1994.
+.RF
+.H 1  "CONCLUSION"
+.P
+The 1988 version of \f5ksh\fP has tens of thousands of regular users
+and is a suitable replacement for the Bourne shell.
+The 1993 version of \f5ksh\fP is essentially upward compatible with
+both the 1988 version of \f5ksh\fP and with the recent IEEE POSIX
+and ISO shell standard.
+The 1993 version offers many advantages for programming applications,
+and it has been rewritten so that it can be used in embedded applications.
+It also offers improved performance.

+.SH DESCRIPTION
+.PP
+The \fIShell\fP library is a set of functions used for
+writing extensions to \f5ksh\fP or writing commands
+that embed shell command processing.
+The include file \f5<shell.h>\fP contains the type definitions,
+function prototypes and symbolic constants defined by
+this interface.  It also defines replacement definitions for
+the standard library functions
+\f5access()\fP,
+\f5close()\fP,
+\f5dup()\fP,
+\f5exit()\fP,
+\f5fcntl()\fP,
+\f5lseek()\fP,
+\f5open()\fP,
+\f5pipe()\fP,
+\f5read()\fP,
+and
+\f5write()\fP
+that must be used
+with all code
+intended to be compiled as built-in commands.
+.P
+The \f5<shell.h>\fP header includes \f5<ast.h>\fP which
+in turn includes the standard include files, \f5<stddef.h>\fP,
+\f5<stdlib.h>\fP, \f5<stdarg.h>\fP, \f5<limits.h>\fP,
+\f5<stdio.h>\fP, \f5<string.h>\fP, \f5<unistd.h>\fP,
+\f5<sys/types.h>\fP, \f5<fcntl.h>\fP, and \f5<locale.h>\fP.
+The \f5<shell.h>\fP header also includes the headers
+\f5<cdt.h>\fP,
+\f5<cmd.h>\fP,
+\f5<sfio.h>\fP,
+\f5<nval.h>\fP,
+\f5<stk.h>\fP,
+and \f5<error.h>\fP
+so that in most cases, programs only require the single
+header \f5<shell.h>\fP.
+.PP
+Programs can use this library in one of the following ways:
+.PD 0
+.TP
+.B 1
+To write builtin commands and/or other code that will be loaded
+into the shell by loading dynamic libraries
+at run time using the \f5builtin\fP(1) command.
+In this case the shell will look for a function named \f5lib_init\fP
+in your library and, if found, will execute this function with
+argument \f50\fP when the library is loaded.
+In addition, for each argument named on the \f5builtin\fP
+command line, it will look for a function named \f5b_\fP\fIname\fP\f5()\fP
+in your library and will \fIname\fP as a built-in.
+.TP
+.B 2
+To build separate a separate command that uses the shell as a
+library at compile or run time.
+In this case the \f5sh_init()\fP function must be called to
+initialize this library before any other commands in this library
+are invoked.
+The arguments \fIargc\fP and \fIargv\fP are the number
+of arguments and the vector of arguments as supplied by the shell.
+It returns a pointer the \f5Shell_t\fP.
+.TP
+.B 3
+To build a new version of \f5ksh\fP with extended capabilities,
+for example \f5tksh\fP(1).
+In this case, the user writes a \f5main()\fP function that
+calls \f5sh_main()\fP with the \fIargc\fP and \fIargv\fP arguments
+from \f5main\fP and pointer to function, \fIfn\fP as a third
+argument..  The function \fIfn\fP will
+be invoked with argument \f50\fP after \f5ksh\fP has done initialization,
+but before \f5ksh\fP has processed any start up files or executed
+any commands.  The function \fIfn\fP
+will be invoked with an argument of \f51\fP before \f5ksh\fP
+begins to execute a script that has been invoked by name
+since \f5ksh\fP cleans up memory and long jumps back to
+the beginning of the shell in this case.
+The function \fIfn\fP will be called with argument \f5-1\fP before
+the shell exits.
+.PD
+.PP
+The \f5Shell_t\fP structure contains the following fields:
+.nf
+.ft 5
+	Shopt_t	\fIoptions\fP;		\fR/* set -o options */\fP
+	Dt_t	*\fIvar_tree\fP;		\fR/* shell variable dictionary */\fP
+	Dt_t	*\fIfun_tree\fP;		\fR/* shell function dictionary */\fP
+	Dt_t	*\fIalias_tree\fP;		\fR/* shell alias dictionary */\fP
+	Dt_t	*\fIbltin_tree\fP;		\fR/* shell built-in dictionary */\fP
+	Shscope_t	*\fItopscope\fP;		\fR/* pointer to top-level scope */\fP
+	char	*\fIinfile_name\fP;	\fR/* path name of current input file*/\fP
+	int	\fIinlineno\fP;		\fR/* line number of current input file*/\fP
+	int	\fIexitval\fP;		\fR/* most recent exit value*/\fP
+.ft R
+.fi
+This structure is returned by \f5sh_init()\fP but can also be retrieved
+by a call to \f5sh_getinterp()\fP.
+.PP
+All built-in commands to the shell are invoked with
+three arguments.  The first two arguments give the
+number of arguments and the argument list
+and uses the same conventions as the \f5main()\fP function
+of a program.  The third argument is a pointer that
+can be associated with each built-in.
+The \f5sh_addbuiltin()\fP function is used to add, replace or delete
+built-in commands. 
+It takes the name of the built-in, \fIname\fP, a pointer
+to the function that implements the built-in, \fIfn\fP, and
+a pointer that will be passed to the function when
+it is invoked.
+If, \fIfn\fP is non-\f5NULL\fP the built-in command
+is added or replaced.  Otherwise, the given
+built-in command will be deleted.
+The \fIname\fP argument can be in the format of a pathname.
+It cannot be the name of any of the special built-in commands.
+If \fIname\fP contains a \f5/\fP, the built-in is the basename of
+the pathname and the built-in will only be executed
+if the given pathname is encountered when performing
+a path search.
+When adding or replacing a built-in,
+\f5sh_addbuiltin()\fP function returns a pointer to
+the name-value pair corresponding to the built-in on success and \f5NULL\fP
+if it is unable to add or replace the built-in.
+When deleting a built-in, \f5NULL\fP is returned on success or
+if not found, and the name-value pair pointer is returned if the built-in
+cannot be deleted.
+.PP
+The functions \f5sh_onoption()\fP, \f5sh_offoption()\fP, \f5sh_isoption()\fP
+are used to set, unset, and test for shell options respectively.
+The \fIoption\fP argument can be any one of the following:
+.IP
+\f5SH_ALLEXPORT\fP:
+The \f5NV_EXPORT\fP attribute is given to each variable whose
+name is an identifier when a value is assigned.
+.IP
+\f5SH_BGNICE\fP:
+Each background process is run at a lower priority.
+.IP
+\f5SH_ERREXIT\fP:
+Causes a non-interactive shell to exit when a command,
+other than a conditional command, returns non-zero.
+.IP
+\f5SH_EMACS\fP:
+The emacs editing mode.
+.IP
+\f5SH_GMACS\fP:
+Same as the emacs editing mode except for the behavior of CONTROL-T.
+.IP
+\f5SH_HISTORY\fP:
+Indicates that the history file has been created and that
+commands can be logged.
+.IP
+\f5SH_IGNOREEOF\fP:
+Do not treat end-of-file as exit.
+.IP
+\f5SH_INTERACTIVE\fP:
+.IP
+Set for interactive shells.
+Do not set or unset this option.
+\f5SH_MARKDIRS\fP:
+A \fB/\fP is added to the end of each directory generated by pathname
+expansion.
+.IP
+\f5SH_MONITOR\fP:
+Indicates that the monitor option is enabled for job control.
+.IP
+\f5SH_NOCLOBBER\fP:
+The \fB>\fP redirection will fail if the file exists.  Each file
+created with \fB>\fP will have the \f5O_EXCL\fP bit set as described
+in \f5<fcntl.h>\fP
+.IP
+\f5SH_NOGLOB\fP:
+Do not perform pathname expansion.
+.IP
+\f5SH_NOLOG\fP:
+Do not save function definitions in the history file.
+.IP
+\f5SH_NOTIFY\fP:
+Cause a message to be generated as soon as each background job completes.
+.IP
+\f5SH_NOUNSET\fP:
+Cause the shell to fail with an error of an unset variable is
+referenced.
+.IP
+\f5SH_PRIVILEGED\fP:
+.IP
+\f5SH_VERBOSE\fP:
+Cause each line to be echoed as it is read by the parser.
+.IP
+\f5SH_XTRACE\fP:
+Cause each command to be displayed after all expansions, but
+before execution.
+.IP
+\f5SH_VI\fP:
+The vi edit mode.
+.IP
+\f5SH_VIRAW\fP:
+Read character at a time rather than line at a time when
+in vi edit mode.
+.IP
+.PP
+The \f5sh_trap()\fP function can be used to compile and execute
+a string or file.
+A value of \f50\fP for \fImode\fP indicates that \fIname\fP
+refers to a string.  A value of \f51\fP for \fImode\fP
+indicates that \fIname\fP is an \f5Sfio_t*\fP to an open stream.
+A value of \f52\fP for \fImode\fP indicates that \fIname\fP
+points to a parse tree that has been returned by \f5sh_parse()\fP.
+The complete file associated with the string or file
+is compiled and then executed so that aliases defined
+within the string or file will not take effect until
+the next command is executed.
+.PP
+The \f5sh_eval()\fP function executes a string or file
+stream \fIsp\fP.
+If \fImode\fP is non-zero and the history file has
+been created, the stream defined by \fIsp\fP
+will be appended to the history file as a command.
+.PP
+The \f5sh_parse()\fP function takes a pointer to the
+shell interpreter \fIshp\fP, a pointer to a string or file stream
+\fIsp\fP, and compilation flags, and returns a pointer
+to a parse tree of the compiled stream.  This pointer can
+be used in subsequent calls to \f5sh_trap()\fP.
+The compilation flags can be zero or more of the following:
+.IP
+\f5SH_NL\fP:
+Treat new-lines as \fB;\fP.
+.IP
+\f5SH_EOF\fP:
+An end of file causes syntax error.  By default it will
+be treated as a new-line.
+.PP
+\f5ksh\fP executes each function defined with the \f5function\fP
+reserved word in a separate scope.  The \f5Shscope_t\fP type
+provides an interface to some of the information that
+is available on each scope.  The structure contains
+the following public members:
+.nf
+      \f5Sh_scope_t      *par_scope;\fP
+      \f5int             argc;\fP
+      \f5char            **argv;\fP
+      \f5char            *cmdname;\fP
+      \f5Dt_t      	 *var_tree;\fP
+.fi
+The \f5sh_getscope()\fP function can be used to the the
+scope information associated with existing scope.
+Scopes are numbered from \f50\fP for the global scope
+up to the current scope level.  The \fIwhence\fP
+argument uses the symbolic constants associated with \f5lseek()\fP
+to indicate whether the \f5Iscope\fP argument is absolute,
+relative to the current scope, or relative to the topmost scope.
+The\f5sh_setscope()\fP function can be used to make a
+a known scope the current scope.  It returns a pointer to the
+old current scope.
+.PP
+The \f5sh_funscope()\fP function can be used to run a function
+in a new scope.  The arguments \fIargc\fP and \fIargv\fP
+are the number of arguments and the list of arguments
+respectively.  If \fIfn\fP is non-\f5NULL\fP, then
+this function is invoked with \fIargc\fP, \fIargv\fP, and \fIarg\fP
+as arguments.
+.PP
+The \f5sh_fun()\fP function can be called within a
+discipline function or built-in extension to execute a
+discipline function script. 
+The argument \fIfunnode\fP is a pointer to the shell function
+or built-in to execute.
+The argument \fIvarnode\fP is a pointer to the name
+value pair that has defined this discipline.
+The array \fIargv\fP is a \f5NULL\fP terminated list of
+arguments that are passed to the function. 
+.PP
+By default, \f5ksh\fP only records but does not act
+on signals when running a built-in command.
+If a built-in takes a substantial amount of time
+to execute, then it should check for interrupts
+periodically by calling \f5sh_sigcheck()\fP.
+If a signal is pending, \f5sh_sigcheck()\fP will exit
+the function you are calling and return to the point
+where the most recent built-in was invoked, or where
+\f5sh_eval()\fP or \f5sh_trap()\fP was called.
+.PP
+The \f5sh_delay()\fP function is used to cause the
+shell to sleep for a period of time defined by \fIsec\fP.
+.PP
+The \f5sh_fmtq()\fP function can be used to convert a string
+into a string that is quoted so that it can be reinput
+to the shell. The quoted string returned by \f5sh_fmtq\fP
+may be returned on the current stack, so that it
+must be saved or copied.
+.PP
+The \f5sh_fdnotify()\fP function causes the function \fIfn\fP
+to be called whenever the shell duplicates or closes a file.
+It is provided for extensions that need to keep track of
+file descriptors that could be changed by shell commands.
+The function \fIfn\fP is called with two arguments.
+The first argument is the original file descriptor.  The
+second argument is the new file descriptor for duplicating
+files, and \f5SH_FDCLOSE\fP when a file has been closed.
+The previously installed \f5sh_fdnotify()\fP function pointer
+is returned.
+.PP
+The \f5sh_waitnotify()\fP function causes the function \fIfn\fP
+to be called whenever the shell is waiting for input from
+a slow device or waiting for a process to complete.
+This function can process events and run shell commands
+until there is input, the timer is reached or a signal arises.
+It is called with three arguments. The first is the file
+descriptor from which the shell trying to read  or \f5\-1\fP
+if the shell is waiting for a process to complete.
+The second is a timeout in milliseconds.
+A value of \f5\-1\fP for the timeout means that
+no timeout should be set.
+The third argument is 0 for input file descriptors
+and 1 for output file descriptor. 
+The function needs to return a value \f5>0\fP if there
+is input on the file descriptor, and a value \f5<0\fP
+if the timeout is reached or a signal has occurred.
+A value of \f50\fP indicates
+that the function has returned without processing and that the shell
+should wait for input or process completion.
+The previous installed \f5sh_waitnotify()\fP function pointer is returned.
+.PP
+The \f5sh_iogetiop()\fP function returns a pointer to the
+Sfio stream corresponding to file descriptor number \fIfd\fP
+and the given mode \fImode\fP.  The mode can be either
+\f5SF_READ\fP or \f5SF_WRITE\fP.
+The \fIfd\fP argument can the number of an open file descriptor or
+one of the following symbolic constants:
+.IP
+\f5SH_IOCOPROCESS\fP:
+The stream corresponding to the most recent co-process.
+.IP
+\f5SH_IOHISTFILE\fP:
+The stream corresponding to the history file.
+If no stream exists corresponding to \fIfd\fP or the stream
+can not be accessed in the specified mode, \f5NULL\fP is returned.

+	    # http://www.opensolaris.org/os/project/ksh93-integration/
+	    # These flags all have a purpose, even if they look
+	    # weird/redundant/etc. at the first look.
+	    #
+	    # 2. We use -KPIC here since -Kpic is too small on 64bit sparc and
+            # on 32bit it's close to the barrier so we use it for both 32bit and
+            # 64bit to avoid later suprises when people update libast in the
+            # future
+	    #
+            # 3. "-D_map_libc=1" is needed to force map.c to add a "_ast_" prefix to all
+            # AST symbol names which may otherwise collide with Solaris/Linux libc
+            #
+            # 4. "-DSHOPT_SYSRC" enables /etc/ksh.kshrc support (AST default is currently
+            # to enable it if /etc/ksh.kshrc or /etc/bash.bashrc are available on the
+            # build machine).
+            #
+	    # 5. -D_lib_socket=1 -lsocket -lnsl" was added to make sure ksh93 is compiled
+            # with networking support enabled, the current AST build infratructure has
+            # problems with detecting networking support in Solaris.
+	    #
+	    # 6. "-xc99=%all -D_XOPEN_SOURCE=600 -D__EXTENSIONS__=1" is used to force
+	    # the compiler into C99 mode. Otherwise ksh93 will be much slower and lacks
+	    # lots of arithmethic functions.
+	    #
+	    # 7. "-D_TS_ERRNO -D_REENTRANT" are flags taken from the default OS/Net
+	    # build system.
+            #
+            # 8. "-xpagesize_stack=64K -xpagesize_heap=64K" is used on SPARC to
+            # enhance the performace
+	    #
+	    # 9. -DSHOPT_CMDLIB_BLTIN=0 -DSH_CMDLIB_DIR=\\\"/usr/ast/bin\\\" -DSHOPT_CMDLIB_HDR=\\\"/home/test001/ksh93/ast_ksh_20070322/solaris_cmdlist.h\\\"

+# buildksh93.readme
+#
+
+* Intro:
+"buildksh93.ksh" is a small build script used to build the AT&T "ast-ksh"
+and "ast-open" packages using its native (nmake-based) build system
+which is needed to build the iffe-generated (header) files (each time
+for { 32bit SPARC, 64bit SPARC, 32bit i386, 64bit AMD64 }) which are
+moved later to their matching OS/Net build directories.
+
+
+* Note that buildksh93.ksh modifies the build behaviour of the AST build
+system, including enforcing C99/XPG6 semantics (which is MANDATORY!!)
+and feeding additional libraries (like libnsl, libsocket, librt etc.)
+to the feature look system (called "iffe" (="if feature exists")) to
+ensure all features needed for the Solaris version of ksh93 are
+properly found.
+
+
+* Example usage of the script (more information can be found in the
+script itself):
+## Download AT&T ksh93 sources
+$ wget --http-user="I accept www.opensource.org/licenses/cpl" --http-passwd="." 'http://www.research.att.com/sw/download/beta/INIT.2007-04-18.tgz'
+$ wget --http-user="I accept www.opensource.org/licenses/cpl" --http-passwd="." 'http://www.research.att.com/sw/download/beta/ast-ksh.2007-04-18.tgz'
+
+## Unpack the sources (32bit SPARC):
+$ mkdir build32_sparc
+$ cd build32_sparc
+$ gunzip -c ../INIT.2007-03-28.tgz | tar -xf -
+$ gunzip -c ../ast-ksh.2007-03-28.tgz | tar -xf -
+
+## Build ast-ksh for 32bit SPARC (build other build flags are:
+# - "build.solaris.sparc.32bit.suncc" - 32bit SPARC
+# - "build.solaris.sparc.64bit.suncc" - 64bit SPARC
+# - "build.solaris.i386.32bit.suncc"  - 32bit x86/i386
+# - "build.solaris.i386.64bit.suncc"  - 64bit x86/AMD64
+# )
+$ time nice ksh ../buildksh93.ksh "build.solaris.sparc.32bit.suncc" 2>&1 | tee -a buildlog.log
+
+## Test ksh93
+$ time nice ksh ../buildksh93.ksh "testshell" 2>&1 | tee -a buildlog.log
+
+## Generated binaries and headers can be found in the arch/$(PLATFORM)/
+## subdirectory.
+
+
+# EOF.
