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
