SUMMARY = "Very high-quality data compression program"
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."
