II. Why COMPRESS?
-----------------

 I wrote this script, because I needed it to speed up DMreply, a script for
 EMS (Elecronic Mail System, the FidoNet/Usnet mailprocessor for the Amiga),
 which was written be Davide Massarenti, who is a VERY GOOD C++ programmer,
 but also uses C++-source-style for ARexx, which DRAMATICALLY slows down
 ARexx. This is because ARexx is no compiler but a Line-By-Line script-
 interpreter, which will be faster if more stuff is written in one line.

 This little script will remove all unnecessary stuff from any ARexx-Script,
 what might speed it up very much.



III. Requirements
-----------------

 - WB & KS 2.04 or higher, may run under 1.x, but not tested!
 - ARexx Version 1.15 (included in the original OS 2.0 - Packet).
   May also work with versions <1.15, but not tested.
 - Rexxsupport.library in libs:



IV. Usage
---------

 RX CRUNCH <infile> <outfile> [max. line-length] [FORCE]
                                Default: 1024

  Option FORCE: This will override the security checks.


 Important notes:

  - NEVER DELETE YOUR ORIGINAL SCRIPT!!!
    It will be very hard to find an error in a crunched script!!!

  - ONLY CRUNCH A SCRIPT WHEN IT IS REALLY WORKING!!!

  - NEVER CRUNCH IT TWICE!



V. History
----------
