Please, test it and report any bugs you find.

Plzip is a massively parallel (multi-threaded) implementation of lzip, fully compatible with lzip 1.4 or newer. Plzip uses the compression library lzlib.

Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip uses a simplified form of the 'Lempel-Ziv-Markov chain-Algorithm' (LZMA) stream format, chosen to maximize safety and interoperability. Lzip can compress about as fast as gzip (lzip -0) or compress most files more than bzip2 (lzip -9). Decompression speed is intermediate between gzip and bzip2. Lzip is better than gzip and bzip2 from a data recovery perspective. Lzip has been designed, written, and tested with great care to replace gzip and bzip2 as the standard general-purpose compressed format for unix-like systems.

Plzip can compress/decompress large files on multiprocessor machines much faster than lzip, at the cost of a slightly reduced compression ratio (0.4 to 2 percent larger compressed files). Note that the number of usable threads is limited by file size; on files larger than a few GB plzip can use hundreds of processors, but on files of only a few MB plzip is no faster than lzip.

The lzip file format is designed for data sharing and long-term archiving, taking into account both data integrity and decoder availability.

Changes in this version:

* Plzip now does not even open the output file if the input file is a terminal.

  * Tarlz is mentioned in the manual as an alternative to tar + plzip.
