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. It is patent-free. This archive includes pre-compiled versions (with source) for PPC & x86 BeOS. NEW IN 0.9.0.c (vs 0.9.0b) Fixed some problems in the library pertaining to some boundary cases. This makes the library behave more correctly in those situations. The fixes apply only to features (calls and parameters) not used by bzip2.c, so the non-fixedness of them in previous versions has no effect on reliability of bzip2.c. WHAT'S NEW IN 0.9.0 (as compared to 0.1pl2) ? * Approx 10% faster compression, 30% faster decompression * -t (test mode) is a lot quicker * Can decompress concatenated compressed files * Programming interface, so programs can directly read/write .bz2 files * Less restrictive (BSD-style) licensing * Flag handling more compatible with GNU gzip * Much more documentation, i.e., a proper user manual * Hopefully, improved portability (at least of the library) The command-line options are deliberately very similar to those of GNU Gzip, but they are not identical. I only ported this package to the BeOS so please direct your comments and questions to the original author Julian Seward at: jseward@acm.org or visit his home page at http://www.muraroa.demon.co.uk/ Mirror Download Sites:
