Colorswapper v1.1:

What's the use of this proggy? Well... It does something most graphicstools
on the ST lack. It can rearrange the colororder of the palette without 
destroying the actual picture. A thing that's very nifty if you accidently
mixed up the colors or want to use various colors for rasters.

Usage:

* Doubleclick on COLRCOOK.TTP.
* Enter the name of the degas PI1 (uncompressed!) you want to edit. You can
  also enter nothing and the program will ask for a name later on.
* Select colors with the cursorkeys and <enter> and swap them with <space>.
* When you're done press <esc> and affirm if you want the file saved or
  abandoned.

All there is to it. Simple program, but amazing no-one ever brought
something like this into the public domain.
