No, but the author released a text file detailing the minor differences
between the Squash and Crunch (original) compression routines.  It just
has to do with using a 13-bit table size instead of 12-bit.  What that
means I can't say, except the more bits, the better compression and the
larger the memory requirements.  I think UNIX's compress program uses
14 bits.  (I know one of the Macintosh 'arc'-like programs uses 14)
