   4  * Copyrignt 1998 Bertho A. Stultiens (BS)
   5  *
   6  * 20-Jun-1998 BS       - Added -L option to prevent case conversion
   7  *                        of embedded filenames.
   8  *
   9  * 08-Jun-1998 BS       - Added -A option to generate autoregister code
  10  *                        for winelib operation.
  11  *
  12  * 21-May-1998 BS       - Removed the CPP option. Its internal now.
  13  *                      - Added implementations for defines and includes
  14  *                        on the commandline.
  15  *
  16  * 30-Apr-1998 BS       - The options now contain nearly the entire alphabet.
  17  *                        Seems to be a sign for too much freedom. I implemeted
  18  *                        most of them as a user choice possibility for things
  19  *                        that I do not know what to put there by default.
  20  *                      - -l and -L options are now known as -t and -T.
  21  *
  22  * 23-Apr-1998 BS       - Finally gave up on backward compatibility on the
  23  *                        commandline (after a blessing from the newsgroup).
  24  *                        So, I changed the lot.
  25  *
  26  * 17-Apr-1998 BS       - Added many new command-line options but took care
  27  *                        that it would not break old scripts (sigh).
  28  *
  29  * 16-Apr-1998 BS       - There is not much left of the original source...
  30  *                        I had to rewrite most of it because the parser
  31  *                        changed completely with all the types etc..
