actually the "bar -Z" compression is not via pack(1) but by compress(1)
which uses the "Lempel-Ziv" compression coding method, FAR superior to
pack ("Huffman coding") or compact ("Adaptive Huffman coding"). Sun did a
nice job with bar, I regularly get around 3 meg of material on a 1.44 meg
floppy using bar -Z.
