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
