.SH NAME
plzip \- reduces the size of files
.SH SYNOPSIS
.B plzip
[\fI\,options\/\fR] [\fI\,files\/\fR]
.SH DESCRIPTION
Plzip \- Parallel compressor compatible with lzip.
Plzip is a massively parallel (multi\-threaded) implementation of lzip, fully
compatible with lzip 1.4 or newer. Plzip uses the lzlib compression library.
.PP
Lzip is a lossless data compressor with a user interface similar to the
one of gzip or bzip2. 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.
.PP
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.
