lunzip \- decompressor for the lzip format
.SH SYNOPSIS
.B lunzip
[\fI\,options\/\fR] [\fI\,files\/\fR]
.SH DESCRIPTION
Lunzip is a decompressor for the lzip format. It is written in C and its
small size makes it well suited for embedded devices or software
installers that need to decompress files but don't need compression
capabilities. Lunzip is fully compatible with lzip\-1.4 or newer.

.PP
Lunzip provides a 'low memory' mode able to decompress any file using as
little memory as 50 kB, irrespective of the dictionary size used to
compress the file. To activate it, specify the size of the output buffer
with the '\-\-buffer\-size' option and lunzip will use the decompressed
with the option \fB\-\-buffer\-size\fR and lunzip will use the decompressed
file as dictionary for distances beyond the buffer size. Of course, the
smaller the buffer size used in relation to the dictionary size, the
larger the difference between the buffer size and the dictionary size, the
more accesses to disk are needed and the slower the decompression is.
This 'low memory' mode only works when decompressing to a regular file
and is intended for systems without enough memory (RAM + swap) to keep

Buffer sizes 12 to 29 are interpreted as powers of two, meaning 2^12
to 2^29 bytes.
.PP
To extract all the files from archive 'foo.tar.lz', use the commands
\&'tar \fB\-xf\fR foo.tar.lz' or 'lunzip \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 (eg, bug) which
caused lunzip to panic.
.PP
The ideas embodied in lunzip 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).
