Package bzip2: Information

bzip2 is a freely available, patent-free, high quality data compressor.

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 (such as gzip), and approaches the
performance of the PPM family of statistical compressors.  bzip2 is
by far not the fastest compression utility, but it does strike a
balance between speed and compression capability.

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