%description
LZMA SDK provides documentation, samples, header files, libraries,
and tools for developing applications with LZMA support.

LZMA uses a dictionary compression algorithm (a variant of LZ77, with
huge dictionary sizes and special support for repeatedly used match
distances), whose output is then encoded with a range encoder, using
a model to make a probability prediction of each bit.
LZMA yields around 20%% better compression when operating at approximately
zlib's speed, and around 40%% when trading more time.
