MacBzip2 Software:

Here you are the last version of MacBzip2. If you don't like it; you can take the source code and make a better one :)

MacBzip2 0.0b2: Julian Seward's bzip2 ported to the Macintosh by SPDsoft. Available for PowerPC and 68K Macintosh as FAT binary (194 Kb); (StuffIt 5.x '.sit' format.).

bzip2 0.1pl2: bzip2 FAT tool. (78 Kb); (StuffIt '.sit' format.).
MacBzip2 0.0b2 Sources: Sources for Metrowerks IDE 3.3 (587 Kb SutffIt 5.x file)

Quoting bzip2 Home Page: "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, whilst being around twice as fast at compression and six times faster at decompression."

So MacBzip2 is simply bzip2 ported to MacOS. Currently, it will run on any Macintosh with 68020 or better CPU and on any PowerMac running system 7.0 or later.

bzip2 is very similar to gzip in it's origin and usage; and the same applies to MacBzip2, so you should read MacGzip pages, I won't repeat here all that information...

BETA WARNING!

Please, note this is the very first MacBzip2 release. bzip2 code passes the tests included with bzip2 sources; and Macintosh code has been tested a lot on MacGzip; but I can't be sure it works on every situation.
So, if you want to use it to backup some very important files be warned:

bzip2 is not a backup tool
MacBzip2 is still not too much tested

Anyway if you are deleting your originals after compressing them, you should compare them against the expanded ones first. "Checksum" may help here.
