I think there was a recent posting of the 'compress' utility to apple-l, although only for the GS. I didn't look at it closely to see if it was actually the same algorithm as the Unix version (which the .Z represents). Support for that would be a nice addition to ShrinkIt, the algorithm is the modified lempel-ziv also used by Stuffit on the Mac (although Stuffit adds an archive structure around it). Tar is a BSD utility (Tape ARchive). There is a compatible version on the Mac (made by the GNU Project). There is also a PD program on Unix that supports Tar and CPIO (the System V version) called Pax (Portable Archive eXchange?, also an indicator of the fight in Unix over which is the preferable format). This program could probably be ported to the Apple if someone wished to. So. Now you have all this information and still no help (unless you count the Mac in your "Apple"). Your best bet is to find someone on a Unix system near you and ask them to do it for you. Given that you're on pro-europa, why don't you rcp it to pro-angmar!nazgul and I'll unpack it for you and send back the pieces.
