<sect3><title>Bzip2</title>

<para>
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.
