How AI describes bzip2

bzip2 is a free, open-source command-line file compression program developed by Julian Seward that uses the Burrows–Wheeler transform to compress single files, producing .bz2 files rather than archives. It runs on major operating systems, is distributed under a BSD-like license, and offers about 15 command-line options for power users and batch processing, but it cannot compress multiple files into a single archive. The program emphasizes high compression with fast decompression, can recover some data from damaged media, and there is no premium version, though the last stable release was in 2010.
