SUMMARY="A generic-purpose lossless compression algorithm"
DESCRIPTION="A generic-purpose lossless compression algorithm that \
compresses data using a combination of a modern variant of the LZ77 algorithm, \
Huffman coding and 2nd order context modeling, with a compression ratio \
comparable to the best currently available general-purpose compression \
methods. It is similar in speed with deflate but offers more dense compression."
