Lunzip is a decompressor for the lzip format written in C. 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
to decompress files but don't need compression capabilities. Lunzip is
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.
The lzip file format is designed for data sharing and long-term archiving,
