  /* 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.
