Squashed is Crunched, but using an extra bit (13 v.s. 12), and no repeat
packing.  I wrote an unarc for the ST supporting it (pkunarc might be it under
a different name - pk are the PC version author's initals).  There is VMS
source available (I found elsewhere) that was _supposed_ to do unsquashing,
and I simply hacked it until it worked for the ST.  Actually, the compression
used by ARC/PKARC comes right out of compress (also available on USENET),
but hacked differently (repeat packing added for crunching, limiting to X bits,
etc.).
