I was searching for an ASCII <-> PETSCII converter and couldn't find anything
on Aminet. I found the source to petcom on "The Fridge"
(http://www.ffd2.com/fridge/) and simply recompiled it for AmigaOS.

Usage:

petcom INPUTFILE >OUTPUTFILE

The converter is able to convert from PETSCII to ASCII or vice versa. It
automatically detects which file is the PETSCII file.
