Clzip is a lossless data compressor with a user interface similar to the
one of gzip or bzip2. Clzip is about as fast as gzip, compresses most
files more than bzip2, and is better than both from a data recovery
perspective. Clzip is a clean implementation of the LZMA "algorithm".

Clzip uses the lzip file format; the files produced by clzip are fully
compatible with lzip-1.4 or newer, and can be rescued with lziprecover.

Clzip is able to compress and decompress streams of unlimited size by
automatically creating multi-member output. The members so created are

There is no such thing as a "LZMA algorithm"; it is more like a "LZMA
coding scheme". For example, the option '-0' of lzip uses the scheme in
almost the simplest way possible; issuing the longest match it can find,
or a literal byte if it can't find a match. Inversely, a much more
elaborated way of finding coding sequences of minimum price than the one
currently used by lzip could be developed, and the resulting sequence
could also be coded using the LZMA coding scheme.
In spite of its name (Lempel-Ziv-Markov chain-Algorithm), LZMA is not a
concrete algorithm; it is more like "any algorithm using the LZMA coding
scheme". For example, the option '-0' of lzip uses the scheme in almost
the simplest way possible; issuing the longest match it can find, or a
literal byte if it can't find a match. Inversely, a much more elaborated
way of finding coding sequences of minimum size than the one currently
used by lzip could be developed, and the resulting sequence could also
be coded using the LZMA coding scheme.
Clzip currently implements two variants of the LZMA algorithm; fast
(used by option -0) and normal (used by all other compression levels).
