grwalter@watmath.UUCP (Fred Walter) (11/07/86)
This is a short C program that takes c-power/pet ascii on stdin and converts
it to unix ascii on stdout (use -p as the first argument to convert the
other way).
It needs just a straight vanilla compile (ie. "cc cnv.c -o cnv" will do).
It is useful when your transfer program (say xmodem on proterm-128)
doesn't do the conversion for you.

*
* take from stdin a petascii file and convert it to unixascii to sdtout
* (using 10 as the end-of-line indicator)
*
* if the -p option is used then
* take from stdin a unixascii file and convert it to petascii to sdtout
* (using 13 as the end-of-line indicator)
*
* note : this file is meant to be viewed/editted using tabs every 4 spaces
*
* credits : the conversion tables were originally made up by brian hilchie
* and they really are for the c-power petascii
