Tuck - portable, lossless data compression

Tuck is a portable, lossless data compression tool based on the
Burrows-Wheeler transform, thus ensuring good compression ratios.
It currently runs quite slowly (slower than the efficient bzip2 ),
mainly because of the block-sorting algorithms involved.
As of March 2006 (initial release, v0.10) tuck is distributed as a
Mach-O PowerPC command-line program only.
The C source code will be released. A library interface similar to that
of zlib or and libbz2 will be exposed
