+.SH NAME
+lzip \- reduces the size of files
+.SH SYNOPSIS
+.B lzip
+[\fI\,options\/\fR] [\fI\,files\/\fR]
+.SH DESCRIPTION
+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.

+.PP
+If no file names are given, or if a file is '\-', lzip compresses or
+decompresses from standard input to standard output.
+Numbers may be followed by a multiplier: k = kB = 10^3 = 1000,
+Ki = KiB = 2^10 = 1024, M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc...
+Dictionary sizes 12 to 29 are interpreted as powers of two, meaning 2^12
+to 2^29 bytes.
+.PP
+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.
+.PP
+To extract all the files from archive 'foo.tar.lz', use the commands
+\&'tar \fB\-xf\fR foo.tar.lz' or 'lzip \fB\-cd\fR foo.tar.lz | tar \fB\-xf\fR \-'.
+.PP
+Exit status: 0 for a normal exit, 1 for environmental problems (file
+not found, invalid flags, I/O errors, etc), 2 to indicate a corrupt or
+invalid input file, 3 for an internal consistency error (e.g., bug) which
+caused lzip to panic.
+.PP
+The ideas embodied in lzip are due to (at least) the following people:
+Abraham Lempel and Jacob Ziv (for the LZ algorithm), Andrey Markov (for the
+definition of Markov chains), G.N.N. Martin (for the definition of range
+encoding), Igor Pavlov (for putting all the above together in LZMA), and
+Julian Seward (for bzip2's CLI).
