/*
 * Guildelines for writing new highlighting rules for the GNU Enscript.
 *
 * - all pretty-printing states should have a document comment like this:
 *
 *   /**
 *    * Name: c
 *    * Description: C programming language.
 *    * Author: Author Name <author@email.address>
 *    * ...
 *
 *   It is used by enscript's --help-pretty-print option to print
 *   description about supported pretty-printing modes.
 *
 * - BEGIN and END rules must call header() and trailer() subroutines:
 *
 *   state c
 *   {
 *     BEGIN {
 *	 header ();
 *     }
 *     END {
 *	 trailer ();
 *     }
 *
 * - each state and possible help-states should have LANGUAGE_SPECIALS rule:
 *
 *     LANGUAGE_SPECIALS {
 *	 language_print ($0);
 *     }
 *
 * - all printing should be done with the language_print() procedure
 *   instead of the print() primitive.
 *
 * These rules ensures that enscript's --help-pretty-print option works
 * and that the many2html utility script can convert all the
 * --pretty-print supported languages to HTML.

  /* Keywords.

     I built the keyword list using the following PostScript program

	/str 128 string def
	/outFile \(ps.txt)(w)file def
	/proc
	{
	    pop //str cvs outFile exch writestring outFile (\n) writestring
	} bind def

	systemdict /proc load forall
	statusdict /proc load forall
	errordict  /proc load forall

    I then ran:

	sort ps.txt | uniq | fmt > ps.key

    I then went through the list and removed << >> [ ] and obvious Harlequin
    extensions. Many of the keywords remaining are not documented in the Red
    Book but are implemented in some Adobe implementations (especially the
    ones from statusdict). I decided to leave them in.

    And since I don't have emacs (gasp), I wrote a program which takes the
    ps.key file and generates the regular expression. This was faster than
    trying to install emacs and figure out how it works.

    Also note that PostScript doesn't require whitespace in front of keywords.
    In particular, text can follow immediately after any of the following
    characters:

	> { } ) [ ] /

    and can be followed immediately by the following:

	< { } ( [ ] /

    in addition to white space.
