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 currently implements two variants of the LZMA algorithm; fast
(used by option -0) and normal (used by all other compression levels).
