bzip2 is a freely available, patent free (see below), high-quality data compressor. It typically compresses files to within 10% to 15% of the best available techniques (the PPM family of statistical compressors), whilst being around twice as fast at compression and six times faster at decompression. This package provides the utility programs, scripts, documentation, and development files. The associated mingw32-libbz2 package provides the runtime library. bzip2 is a freely available, patent free (see below), high-quality data compressor.
