bzip2: Bzip2 compresses files using the Burrows-Wheeler block sorting text
bzip2: compression algorithm, and Huffman coding. Compression is generally
bzip2: considerably better than that achieved by more conventional LZ77/LZ78-
bzip2: based compressors, and approaches the performance of the PPM family of
bzip2: statistical compressors.
