 Plzip is a massively parallel (multi-threaded), lossless data compressor
 based on the lzlib compression library, with very safe integrity
 checking and a user interface similar to the one of bzip2, gzip or lzip.

    Plzip is intended for faster compression/decompression of big files

 distribution of big software files and large scale data archiving. On
