/*
*
* Copyright Martin von Loewis, 1994
* Copyrignt 1998 Bertho A. Stultiens (BS)
*
* 20-Jun-1998 BS - Added -L option to prevent case conversion
* of embedded filenames.
*
* 08-Jun-1998 BS - Added -A option to generate autoregister code
* for winelib operation.
*
* 21-May-1998 BS - Removed the CPP option. Its internal now.
* - Added implementations for defines and includes
* on the commandline.
*
* 30-Apr-1998 BS - The options now contain nearly the entire alphabet.
* Seems to be a sign for too much freedom. I implemeted
* most of them as a user choice possibility for things
* that I do not know what to put there by default.
* - -l and -L options are now known as -t and -T.
*
* 23-Apr-1998 BS - Finally gave up on backward compatibility on the
* commandline (after a blessing from the newsgroup).
* So, I changed the lot.
*
* 17-Apr-1998 BS - Added many new command-line options but took care
* that it would not break old scripts (sigh).
*
* 16-Apr-1998 BS - There is not much left of the original source...
* I had to rewrite most of it because the parser
* changed completely with all the types etc..
