%description
bzip2 is a high-quality implementation of the Burrows-Wheeler block
sorting based transform, with Huffman coding. This lossless compression
algorithm is in general, considerably better than that achieved by more
conventional LZ77/LZ78 based compressors (like gzip), and competitive
with all but the best of the PPM family of statistical compressors.
bzip2 does not infringe on any known patents, hence it is not compatible
with bzip 0.21 (it uses arithmetic coding, which is patented in the USA).
