-Plzip is a massively parallel (multithreaded) data compressor compatible

-compatible with lzip-1.4 or newer. Plzip is intended for faster
-compression/decompression of big files on multiprocessor machines. On
-files big enough, plzip can use hundreds of processors. Currently only
-compression is performed in parallel. Parallel decompression is planned
-to be implemented later.
