Please, test it and report any bugs you find.

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

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.

Plzip uses the lzip file format; the files produced by plzip are fully 
compatible with lzip-1.4 or newer, and can be rescued with lziprecover.

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:

  * Some changes have been made to reduce memory fragmentation and 
total memory use.

  * When compressing on a 32 bit system, plzip now tries to limit the 
memory use to under 2.22 GiB (4 worker threads at level -9) by reducing 
the number of threads below the system's default. (This is an 
improvement on the limit implemented in -rc1).

  * A block diagram of plzip has been added to the manual.
