Static libraries and include files for the bzip2 compressor library.
.
bzip2 is a freely available, patent free, 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, and approaches the performance of the PPM
family of statistical compressors.
.
The archive file format of bzip2 (.bz2) is incompatible with that of its
predecessor, bzip (.bz).
