Description Plzip is a massively parallel (multithreaded) data compressor compatible with the lzip file format. The files produced by plzip are fully 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. Lzip is a lossless data compressor based on the LZMA algorithm, with very safe integrity checking and a user interface similar to the one of gzip or bzip2. Lzip decompresses almost as fast as gzip and compresses better than bzip2, which makes it well suited for software distribution and data archiving. Copyright (C) 2009, 2010 Antonio Diaz Diaz.
