+HELPDECO - Utility-Programm zum Zerlegen von Windows Hilfedateien
+
+HELPDECO zerlegt HLP-Hilfedateien von Windows 3.0, 3.1, 3.11 und '95 und
+viele MVB-Dateien des Multimedia-Viewers in alle f�r den jeweiligen
+Hilfecompiler HC30, HC31, HCP, HCW, HCRTF, WMVC, MMVC oder MVC zum
+erneuten Zusammenbau erforderlichen Dateien. Dazu geh”ren:
+HPJ - die Projektdatei, als Parameter f�r den Hilfecompiler anzugeben
+MVP - die Multimediaprojektdatei, als Parameter f�r den MM-Compiler
+RTF - die Textdatei mit dem gesamten Hilfetext und allen Fuánoten
+PH  - die Phrasen-Datei (wie sie auch vom Hilfecompiler erzeugt wird)
+ICO - ein eventuell der Hilfedatei zugeordnetes Icon
+BMP/WMF/SHG/MRB - alle Bilder in Dateien mit passendem Format
+Baggage - alle als Baggage in der Hilfedatei enthaltenen Dateien
+
+HELPDECO wird von der MS-DOS Kommandozeile aus mit dem Namen der zu
+bearbeitenden Datei, eventuell dem Namen einer internen Datei und
+eventuellen Optionen aufgerufen. HELPDECO l„uft von der Kommandozeile
+von Windows 95 oder Windows NT als 32-bit Applikation zur Bearbeitung
+grӇerer Hilfedateien.
+
+HELPDECO
+Zeigt Benutzungshinweise
+
+HELPDECO helpfilename
+Zerlegt die Hilfedatei in alle zum erneuten Zusammenbau ben”tigten Dateien.
+Diese Dateien werden im aktuellen (m”glichst leeren) Verzeichnis abgelegt.
+Existierende Dateien werden ohne R�ckfrage �berschrieben wenn die Option /y
+angegeben wird.
+
+Hinter dem Kommando k”nnen durch Leerzeichen abgesetzte Optionen angeben
+werden:
+
+/m
+kann verwendet werden, um das Durchsuchen von macros nach Topicnamen zu
+verhindern, wenn dabei Probleme auftreten. Hilfecompiler wird Warnung 4131
+melden.
+
+/b
+kann verwendet werden, um das Aufl”sen von Browse-Sequenzen zu verhindern,
+wenn dabei Probleme auftreten. Hilfequelltextdatei enth„lt dann keine +
+Fuánoten.
+
+/g
+Schaltet das zeitintensive Raten von Kontextnamen aus. Anzuwenden wenn
+HELPDECO 'no context ids found' meldet oder man nicht an lesbaren
+Kontextnamen interessiert ist. Die Funktionsweise von HELPDECO wird dadurch
+nicht beeintr„chtigt.
+Zum Raten versucht HELPDECO aus Kapitel�berschriften und Schl�sselw”rten
+die Kontextnamen zu rekonstruieren, was bei einigen Hilfedateien sehr gut,
+bei anderen gar nicht funktioniert, je nach Hilfedateierstellungswerkzeug
+oder Arbeitsmethode des Hilfeautors.
+
+/i
+Wenn man sehen m”chte, welche Kontextnamen HELPDECO err„t...
+
+/hprefix
+HELPDECO versucht aus Kapitel�berschriften und Schl�sselw”rtern Kontextnamen
+zu erraten, wobei auch idh_ oder helpid_ vorangestellt werden.
+Wenn die Hilfedatei mit anderen bekannten Prefixen erstellt wurde, kann
+die Tabelle durch die Option /h prefix erweitert werden.
+
+/a [annotationfilename.ANN]
+F�gt zus„tzlich alle Anmerkungen aus der angegebenen Anmerkungsdatei als
+Anmerkungen des Benutzers ANN in die RTF-Datei ein. Fehlt der annotation-
+filename, verwendet HELPDECO helpfilename.ANN daf�r.
+
+/s n
+Zerteilt die Ausgabe alle n Seiten in eine eigene RTF Datei, z.B. zerlegt
+  HELPDECO helpdemo /s 100
+die Datei helpdemo.hlp und erzeugt RTF-Dateien mit den Namen helpdem1.rtf,
+helpdem2.rtf,.. die jeweils h”chstens 100 Seiten enthalten.
+
+HELPDECO helpfilename /r
+Erzeugt aus der Hilfedatei eine RTF-Datei, die von WinWord geladen dasselbe
+Aussehen hat wie die von WinHelp angezeigten Hilfeseiten. Damit kann eine
+Hilfedatei komplett gedruckt oder weiterverarbeitet werden. Zus„tzlich
+Option /n angeben, wenn an Kapitelgrenzen kein Seitenwechsel stattfinden soll.
+
+HELPDECO helpfilename /c
+Erzeugt aus der Hilfedatei eine *.CNT-Datei f�r WinHlp32, die alle Kapitel
+mit šberschriften in der Reihenfolge enth„lt, in der sie in der Hilfedatei
+auftreten. Die Datei muá dann mit HCW 4.00 oder einem Texteditor in eine
+hierarchische Struktur �berarbeitet werden.
+
+HELPDECO helpfilename /e
+Zeigt alle Referenzen auf externe Hilfedateien.
+
+HELPDECO helpfilename /e /f
+Zeigt alle Referenzen auf externe Hilfedateien und die Titel der Topics in
+denen sie auftraten.
+
+HELPDECO helpfilename /p
+Pr�ft Referenzen auf externe Hilfedateien. Die referenzierten Hilfedateien
+m�ssen f�r HELPDECO zugreifbar sein. Dieser Aufruf erzeugt keine neuen
+Dateien und modifiziert keine existierenden. Fehler werden auf stdout (den
+Bildschirm) geschrieben.
+
+HELPDECO helpfilename /d
+Zeigt das interne Inhaltsverzeichnis der Hilfedatei. Es kann auch eine
+*.MVB,*.M??,*.ANN,*.CAC,*.AUX Datei anstelle der *.HLP-Datei angegeben
+werden.
+
+HELPDECO helpfilename /x
+Zeigt das interne Inhaltsverzeichnis als HexDump
+
+HELPDECO helpfilename "internalfilename"
+Zeigt die genannte interne Datei in einem passenden Format an, soweit die
+interne Datei anzeigbar ist, sonst als HexDump. Sie k”nnen die Ausgabe in
+eine Datei umleiten durch anh„ngen von >outfile.
+
+HELPDECO helpfilename "internalfilename" /x
+Zeigt die genannte interne Datei als HexDump
+
+HELPDECO helpfilename "internalfilename" /x /t offset
+Zeigt die genannte interne Datei als HexDump beginnend bei Position
+offset, der als Dezimalzahl oder mit vorangestelltem 0x als Hexadezimal-
+zahl akzeptiert wird.
+
+HELPDECO helpfilename "internalfilename" filename
+Exportiert die genannte interne Datei in filename
+
+*.ANN, *.CAC, *.AUX
+Diese Dateien sind auch wie Hilfedateien formatiert, HELPDECO kann aber nur
+verwendet werden, um ihr Inhaltsverzeichnis anzuzeigen oder um einzelne
+Dateien anzuzeigen und zu exportieren.

+HELPDECO - utility program to dissect Windows help files
+
+HELPDECO dissects HLP help files of Windows 3.0, 3.1, 3.11, and '95 and
+many MVB multi media viewer titles into all files required for a rebuild
+using the appropriate help compiler HC30, HC31, HCP, HCW, HCRTF, WMVC,
+MMVC or MVC:
+HPJ - help project file, use as parameter when calling help compiler
+MVP - multi media project file, parameter for multi media help compiler
+RTF - text file containing whole content of help file and all footnotes
+PH  - phrases file (same as produced by help compiler)
+ICO - icon of help file if embedded
+BMP/WMF/SHG/MRB - embedded pictures in appropriate format
+Baggage - all baggage files contained in help file
+
+Call HELPDECO from MS-DOS command line. Supply name of help file to use,
+optional name of internal file, and options if appropriate.
+HELPDECO runs from Windows 95 or Windows NT command line as 32-bit
+application to handle larger help files.
+
+HELPDECO
+Displays usage
+
+HELPDECO helpfilename
+Decompiles help file into all sources needed for a rebuild. All files are
+created in current directory (should be empty). Existing files will be
+overwritten without asking if option /y was specified.
+
+Options may be appended to the command, separated using blanks, as follows:
+
+/m
+May be used to stop parsing macros for topic names. Help compiler will emit
+Warning 4131.
+
+/b
+May be used to stop resolving browse sequences. Help source file than
+contains no + footnotes.
+
+/g
+Turns off time consuming guessing of context names. Applicable when
+HELPDECO reports 'no context ids found' or when you are not interested in
+legible context ids. This doesn't affect functionality.
+During guessing HELPDECO tries to reconstruct context ids from topic titles
+and keywords. This may produce good results on some help files and no result
+at all on others, depending on autoring tool used or working method of help
+author.
+
+/i
+If you want to see which context ids are guessed by HELPDECO...
+
+/hprefix
+HELPDECO tries to guess context ids from topic titles and keywords, possibly
+prefixed by idh_ or helpid_. If the help file was created using other
+prefixes, they may be added to the table using the /h prefix option.
+
+/a [annotationfilename.ANN]
+Adds all annotations from annotationfile as annotations of user ANN into
+RTF file. Default annotationfilename is helpfilename.ANN.
+
+/s n
+Splits output every n pages into a separate RTF file. For example
+  HELPDECO helpdemo /s 100
+decompiles helpdeco.hlp and creates different RTF files helpdem1.rtf,
+helpdem2.rtf,.. each containing no more than 100 topics.
+
+HELPDECO helpfilename /r
+Converts help file into RTF file of same appearance if loaded into WinWord
+as if displayed by WinHelp. To print or work with complete content. Specify
+additional option /n, if no page breaks should separate topics.
+
+HELPDECO helpfilename /c
+Generates a *.CNT file used by WinHlp32, containing all chapters that have
+titles assigned in the order they appear in the helpfile. This file should
+then be edited using HCW 4.00 or any text editor into a hierarchical order.
+
+HELPDECO helpfilename /e
+Lists all references to external help files.
+
+HELPDECO helpfilename /e /f
+Lists all references to external help files and titles of topics that
+contained these references.
+
+HELPDECO helpfilename /p
+Checks references to external help files. Referenced help file need to be
+available to HELPDECO. This call doesn't produce any new files and doesn't
+modify existing files. Errors are reported to stdout (screen).
+
+HELPDECO helpfilename /d
+Displays internal directory of help file. You may supply a *.MVB,*.M??,
+*.ANN,*.CAC,*.AUX file instead of a *.HLP file.
+
+HELPDECO helpfilename /x
+Displays hex dump of internal directory
+
+HELPDECO helpfilename "internalfilename"
+Displays internal file in appropriate format if known, else hex dump. You

+
+HELPDECO helpfilename "internalfilename" /x
+Displays hex dump of internal file
+
+HELPDECO helpfilename "internalfilename" /x /t offset
+Displays hex dump of internal file starting at offset, which may be
+specified in decimal or preceeded with 0x in hex.
+
+HELPDECO helpfilename "internalfilename" filename
+Exports internal file into filename
+
+*.ANN, *.CAC, *.AUX
+These files are formatted like helpfiles, but HELPDECO can only be used to
+display their internal directory or display or export internal files.

+
+HELPDECO is based upon HELPDUMP from Pete Davis published in:
+The Windows Help File Format, Dr. Dobbs Journal, Sep/Oct 1993
+Thanks to Holger Haase, who did a lot of work on picture file formats.
+And thanks to Juergen Mueller for pointing out 32-bit differences.
+Thanks to Bent Lynggaard for the information on help file free lists
+and his contribution on context id guessing.
+
+See HELPFILE.TXT for a description of the Windows help file format
+as parsed by HELPDECO and related file formats like MRB/SHG.
+
+The newest public version of HELPDECO is always available at:
+CompuServe: Dr. Dobbs Journal DDJFOR Undocumented Corner HELPDCxx.ZIP
+InterNet: ftp://gmutant.wrlc.org/pub/winhelp
+
+HELPDECO is freeware. Use at your own risk. No part of the program may be
+used commercially. No fees may be charged on distributing the program
+(shareware distributors keep off).
+
+The use of parts of decompiled help files may constitute a violation of
+copyright law.
+
+Version 2.1:
+macros may contain rtf meta characters
+Win95 topic names may contain (nearly) all characters
+0x8000 in SWin->Maximize allowed
+ForeHelp creates PhrIndex/PhrImage _and_ _empty_ Phrases file
+HCRTF complained about > footnotes before # footnotes
+macro parsing changed again
+
+Version 2.0:
+Guess context ids from titles and keywords based on idea of Bent Lynggaard
+Recompiled 16 bit EXE without register calling convention. BC++ 3.1 bug.
+Doesn't print last (stray) topic of HC30 help files
+Can list entry points into this help file (option /l)
+
+Version 1.9: faster & better than ever...
+changed TopicPos, TopicOffset, Keyword maintenance
+changed unhash to 40 bit integer arithmetic
+fixed keyword footnotes [Bent Lynggaard]
+no [ALIAS] in MVP files
+no hidden text in option /r RTF files
+some changes in font and stylesheet handling
+corrects rounding error of HC31 on negative values
+handles non-underlined topic jumps
+
+Version 1.8: used some spare days to clean up the to-do list...
+better tracking of TopicOffset during decompilation
+lists and checks references to external files, shows referencing topics
+can add annotations from .ANN file to decompiled .RTF file
+fixed bug in handling of pictures containing JumpId-macro hotspots
+changed parsing of macros (3rd attempt to guess what Microsoft did)
+fixed bug in popup/jump to external file / secondary window
+fixed bug in > footnote / |VIOLA internal file handling
+fixed bug in keyword assignment
+now removes LZ77 compression from exported SHGs/MRBs
+recreates Win 95 (HCW 4.00) [MACROS] section from internal |Rose file
+32 bit version available
+handles LANGUAGE, [CHARTAB] and [GROUP] section of media view files
+
+Version 1.7
+removed unneccessary output statement
+
+Version 1.6 can now check references to external help files plus:
+duplicate macro names preceeding picture hotspot info skipped
+does not write Win95 commands to multi-media help project files
+changed unhash to circumvent Microsoft-C++ float rounding error
+handles keywords defined inside topic text
+
+Version 1.5
+fixed static on buffer of TopicName function (affected HC30 files)
+
+Version 1.4 fixes some bugs reported by different users:
+buffer overflow in expanding LZ77&RunLen (byPacked 3) images fixed
+embedded images {bmxwd} larger than 32k supported
+extract topic names from jump into external file if no file specified
+handles more phrases on HCRTF generated (Win95) help files
+Windows 3.1 (HC31) |Phrases always Zeck compressed
+LinkData2 buffer enlarged 1 byte to store trailing NUL character
+
+Version 1.3
+parses examples of {bmc} etc. statements contained in help text correctly
+can now generate a *.CNT content file for Windows 95 / WinHlp32
+Microsoft C: ctype macros (isalnum/isprint) don't work with signed char
+
+Version 1.2 fixes some severe bugs introduced in version 1.1 and:
+tells you which help compiler to use
+collects multiple keyword footnotes into single lines
+handles \r\n in COPYRIGHT
+converts SPC-macro (but only in [CONFIG] section)
+does not generate duplicate MAP-statements if possible
+{button} and {mci,mci_left,mci_right} commands supported
+[BITMAP]-section in HCRTF help files irritated transparent bitmaps
+
+Version 1.1 now supports more features of Win95/HCRTF 4.00/WinHlp32:
+Supports LCID, CHARSET, AUTO-SIZE HEIGHT, CNT, INDEX_SEPARATORS
+Additional Win95 Macros (to extract original topic names)
+[CONFIG:n] of Win95 supported (internal file |CFn)
+Secondary windows with > footnote supported (internal file |VIOLA)
+Transparent bitmaps supported (bmct,bmlt,bmrt)
+Expanded internal limits as HCRTF allows larger items
+Now does RunLen compressed device dependend bitmaps
+Bugs in handling of metafiles removed
+Bug in placement of pack(1) removed
+Parsing of macros changed (is it really better now ?)
