* Modification Log
* ----------------
* Initial release version 1.0: 87/12/18 Wolf Paul
*
* Revision 1.1 87/12/26 23:34:50 plocher
* Added enviroment variables for HELPDIR and HELPFILE
*
* MS-DOS (Turbo C) version 2.0: 3/28/89 R. Brittain
* Changed open mode on index file to binary
* Changed default directory to /lib
* Made index search non case-senstive
* Added -i option to display index
* Added -k option - code to perform apropos search, added synopsis
* to index structure
* Added code to specify multiple help files in the HELPFILE variable
* All errors are now non-fatal until all helpfiles in list have
* been processed. exit() removed from buildindex()
* Revised syntax:
* set HELPFILE=helpfile1;helpfile2...
* help [-i | -k keyword | command]
* Posted to usenet.
*
* MS-DOS Version 3.0: 10/2/89 R. Brittain
* Rewrote argument handling code. This version no longer bears much
* resemblance to the original code, but functions very similarly if the
* interactive selection is not used. I have added my name to the
* copyright since most of the code is now mine. The original code by
* Wolf Paul bore no copyright so I added his name too.
* I used a routine called popen/pclose which simulates piping without
* the overhead of calling a second copy of HELP. This came from simtel20
* but has no author name as far as I can tell. The relevant files are
* popen.c and getswitc.c.
* Added -1 option to list index, 1 item per line
* Added interactive selection of help from the index via a
* pop-up screen window. This option uses bios video memory calls
* and will not function on non-IBM compatible machines.
* Added -c (clear screen) and -p (pause) options to allow customising
* the behaviour with the interactive selection option.
* Shortened synopsis to 80, lengthened index to 25 (This will break old
* .idx files - must regenerate)
* Compiled in compact model to make sure there is enough heap space
* for the index entries. It would be a real pain to recode using
* farmalloc(). You can save about 5k by compiling in small model
* Added alphabetic sorting of index and apropos listings
* Added conditional compilation for NANSI and BIOS - see makefile
* Added -K option for interactive browsing + apropos
* Modified select_item so it can be fully recursive to allow cross references
* Added cross references with #XREF syntax in help file, and F4 command
* in interactive mode.
* Posted to usenet. Oct 23 1990
*
* MS-DOS Version 3.1: 2/17/91 R. Brittain
* Added -P option to always use PAGER, even if not in browse mode.
* Changed default help directory in the absence of HELPDIR to be the
* directory in which the executable is found, rather than /lib
* Added diagnostic messages in the case no help files are found
