-Plzip is a parallel version of the lzip data compressor. 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. Currently only compression is performed in
-parallel. Parallel decompression is planned to be implemented later.
+Plzip is a massively parallel (multithreaded) data compressor compatible
+with the lzip file format. The files produced by plzip are fully

+compression/decompression of big files on multiprocessor machines. On
+files big enough, plzip can use hundreds of processors. Currently only

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
