%description
Bzip2 compresses files using the Burrows-Wheeler block-sorting text
compression algorithm, and Huffman coding. Compression is generally
considerably better than that achieved by more conventional LZ77/LZ78-based
compressors, and approaches the performance of the PPM family of statistical
compressors.

The command-line options are deliberately very similar to those of GNU Gzip,
but they are not identical.
