Parallel BZIP2 (PBZIP2) - Data Compression Software

PBZIP2 is a parallel implementation of the bzip2 block-sorting file compressor
that uses pthreads and achieves near-linear speedup on SMP machines. The
output of this version is fully compatible with bzip2 v1.0.2 or newer (ie:
anything compressed with pbzip2 can be decompressed with bzip2).

PBZIP2 should work on any system that has a pthreads compatible C++ compiler
(such as gcc). It has been tested on: Linux, Windows (cygwin & MinGW),
Solaris, Tru64/OSF1, HP-UX, and Irix.
