	My experience with compress is that it puts the extension .Z
after the file name while pack uses the extension .z .  A minor 
difference but a difference none the less -- the algorithms and
reduction ratios are vastly different.  Before you spend a lot of
time chasing tools that may not do the job, I recommend you check
on which method was used to create your file.
