PPT is a powerful, free image processing package, that boasts with the
following properties:
- Handles both 24 bit truecolor and 8 bit grayscale images with optional
alpha channel.
- Modular design, ie. you can easily add new loaders and filters to the
program.

the same time! No need to wait for another project to be ready!
- Unlimited (except by available memory) buffers!
- Unlimited (except by available disk space) undo!

- AREXX port
- Font sensitive and scalable GUI using Jan van den Baard's and Ian

OS 3.0 (V39) features. Takes use of AGA chips if installed. CyberGFX
is also supported!

it deletes it. (Suggested by Uwe Pannecke).
