lossless data compressor based on LZMA algorithm

Lzip is a lossless data compressor based on the LZMA (Lempel-Ziv-Markov chain-Algorithm) algorithm designed by Igor Pavlov. The high compression of LZMA comes from combining two basic, well-proven compression ideas: sliding dictionaries (i.e. LZ77/78), and markov models (i.e. the thing used by every compression algorithm that uses a range encoder or similar order-0 entropy coder as its last stage) with segregation of contexts according to what the bits are used for. Lzip is not a replacement for gzip or bzip2, but a complement; which one is best to use depends on user's needs.

Pdlzip
A limited, "public domain" implementation of the lzip data compressor,

intended for those who can't distribute GPL licensed Free Software. Pdlzip is also able to decompress legacy lzma-alone (.lzma) files.
