# $NetBSD: emacs.mk,v 1.23 2005/12/05 22:07:07 rillig Exp $
#
# This Makefile fragment handles Emacs Lisp Packages (== ELPs).
#
# Note to users:
#
#	* Users choose one favoriate Emacs version (default GNU Emacs 21).
#
#	* Emacs Lisp files are installed...
#	  	GNU emacs
#	  		-> ${PREFIX}/share/emacs/site-lisp/foo/...
#		XEmacs
#	  		->${PREFIX}/lib/xemacs/site-packages/lisp/foo/...
#
#	* You can't install an ELP for both Emacs and XEmacs
#	  simultaneously.
#
#	* XEmacs package's names are prefix'ed by "xemacs-".
#
# Note to package developers:
#
#	* XEmacs package's names are prefix'ed by "xemacs-".
#
#	  This is to make sure ELPs for XEmacs keep their own dependency
#	  tree (for example, if an ELP "bar" depends on another ELP "foo",
#	  "xemacs-bar" depends on "xemacs-foo".  "foo" (installed for GNU
#	  Emacs) is useless for "xemacs-bar" in this case.).
#
#	  Make sure too that "foo" and "xemacs-foo" conflict each other,
#	  since they can share some files.  (Making all ELPs separately
#	  installable for GNU Emacs/XEmacs might be possible.)
#
#	* Assume each ELP supports all Emacs versions by default.  If the
#	  ELP supports only certain Emacs versions, define EMACS_VERSIONS
#	  _ACCEPTED explicitly before including mk/emacs.mk.
#
# Variables for users:
#
#	EMACS_TYPE
#		Description:
#			The user's favoriate Emacs version.
#		Possible values:
#			emacs21, emacs21nox, emacs20, xemacs215, xemacs214
#		Default value:
#			emacs21
#
# Variables ELPs can provide:
#
#	EMACS_USE_LEIM
#		Description:
#			Set if the ELP wants LEIM support.
#		Possible values:
#			<undefined>, <defined>
#		Default value:
#			<undefined>
#
#	EMACS_VERSIONS_ACCEPTED
#		Description:
#			Versions the ELP accepts (supports).
#		Possible values:
#			emacs21, emacs21nox, emacs20, xemacs215, xemacs214
#		Default value:
#			emacs21, emacs21nox, emacs20, xemacs215, xemacs214
#	REPLACE_EMACS
#		Description:
#			If set, correct the #!/path/to/emacs line in the
#			specified files.
#		Possible values:
#			<a list of files relative to ${WRKDIR}>
#		Default value:
#			<undefined>
#
# Variables provided for ELPs:
#
#	EMACS_BIN
#		Description:
#			Path to Emacs executable.
#		Possible values:
#			${PREFIX}/bin/emacs, ${PREFIX}/bin/xemacs
#
#	EMACS_ETCPREFIX
#		Description:
#			Path to the directory misc. files should be
#			installed into.  ELPs should append a short
#			name as a subdirectory.
#		Possible values:
#			${PREFIX}/share
#	  		${PREFIX}/lib/xemacs/site-packages/etc
#
#	EMACS_FLAVOR
#		Description:
#			GNU Emacs (emacs) or XEmacs (xemacs).
#		Possible values:
#			emacs, xemacs
#
#	EMACS_INFOPREFIX
#		Description:
#			Path to the directory Info files should be
#			installed into.  Unlike EMACS_ETCPREFIX or
#			EMACS_LISPPREFIX, subdirectory is not needed.
#		Possible values:
#			${PREFIX}/info
#	  		${PREFIX}/lib/xemacs/site-packages/info
#
#	EMACS_LISPPREFIX
#		Description:
#			Path to the directory Emacs lisp files should be
#			installed into.  ELPs should append a short name
#			as a subdirectory.
#		Possible values:
#			${PREFIX}/share/emacs/site-lisp
#	  		${PREFIX}/lib/xemacs/site-packages/lisp
#
#	EMACS_PKGNAME_PREFIX
#		Description:
#			The prefix of PKGNAME and DEPENDS lines.  All ELPs
#			must honour this!
#		Possible values:
#			"", "xemacs-"
#
# Variables provided in ELPs' PLIST:
#
#	EMACS_ETCPREFIX
#		Description:
#			Same as the one in Makefile, except that
#			${PREFIX} is omitted in PLIST.
#		Possible values:
#			share
#	  		lib/xemacs/site-packages/etc
#
#	EMACS_INFOPREFIX
#		Description:
#			Same as the one in Makefile, except that
#			${PREFIX} is omitted in PLIST.
#		Possible values:
#			info
#	  		lib/xemacs/site-packages/info
#
#	EMACS_LISPPREFIX
#		Description:
#			Same as the one in Makefile, except that
#			${PREFIX} is omitted in PLIST.
#		Possible values:
#			share/emacs/site-lisp
#	  		lib/xemacs/site-packages/lisp
#
#	EMACS_VERSION
#		Description:
#			XXX
#		Possible values:
#			XXX
#
#	FOR_{emacs,emacs21,emacs21nox,emacs20,xemacs,xemacs215,xemacs214}
#		Description:
#			These macros will become either an empty string or
#			"@comment" depending on the Emacs version; when
#			"emacs21" is used, ${FOR_emacs} and ${FOR_emacs21}
#			become "" (empty), and other macros become
#			"@comment"; thie means that only the PLIST lines
#			prefixed by ${FOR_emacs} and ${FOR_emacs21} are
#			valid.
#		Possible values:
#			"", "@comment"
#
#	NOTFOR_{emacs,emacs21,emacs21nox,emacs20,xemacs,xemacs215,xemacs214}
#		Description:
#			The opposite of FOR_*.  See above.
#		Possible values:
#			"", "@comment"
