.SH DESCRIPTION
Plzip is a massively parallel (multi\-threaded) implementation of lzip, fully
Plzip is a massively parallel (multi\-threaded) implementation of lzip,
compatible with lzip 1.4 or newer. Plzip uses the compression library lzlib.
.PP
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 and provides a 3 factor integrity
checking to maximize interoperability and optimize safety. Lzip can compress
about as fast as gzip (lzip \fB\-0\fR) or compress most files more than bzip2
(lzip \fB\-9\fR). 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.

The bidimensional parameter space of LZMA can't be mapped to a linear
scale optimal for all files. If your files are large, very repetitive,
etc, you may need to use the options \fB\-\-dictionary\-size\fR and \fB\-\-match\-length\fR
directly to achieve optimal performance.
