File: BZip2-0.9.0b-ppc.pkg
Author: Michael Griebling (

Release: V0.9.0b for BeOS, 31 December 1998
Compatibility: R3/R4
Location: contrib/util
Description: Gzip-like utility with much better compression.
Notes: Now includes precompiled binaries.
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 around twice as fast at compression and six
times faster at decompression than other compressors and it
is patent-free. This archive includes a pre-compiled version for
BeOS. The x86 version of this utility only has a crude installer
since PackageBuilder for x86 is not yet available.
The command-line options are deliberately very similar to
those of GNU Gzip, but they are not identical.
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)
I only ported this package to the BeOS so please direct
