NAME
minilzip - reduces the size of files
SYNOPSIS
minilzip [options] [files]
DESCRIPTION
Minilzip is a test program for the compression library lzlib, compatible with lzip 1.4 or
newer.
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 to maximize interoperability. The maximum dictionary size is 512 MiB so that
any lzip file can be decompressed on 32-bit machines. Lzip provides accurate and robust
3-factor integrity checking. Lzip can compress about as fast as gzip (lzip -0) or compress
most files more than bzip2 (lzip -9). 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.

If no file names are given, or if a file is '-', minilzip 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.
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
--dictionary-size and --match-length directly to achieve optimal performance.
To extract all the files from archive 'foo.tar.lz', use the commands 'tar -xf foo.tar.lz'
or 'minilzip -cd foo.tar.lz | tar -xf -'.
Exit status: 0 for a normal exit, 1 for environmental problems (file not found, invalid
command-line options, I/O errors, etc), 2 to indicate a corrupt or invalid input file, 3
for an internal consistency error (e.g., bug) which caused minilzip to panic.
The ideas embodied in lzlib are due to (at least) the following people: Abraham Lempel and
Jacob Ziv (for the LZ algorithm), Andrei 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).
