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.
[...]
It's free (GNU GPL'd), and, as far as I know, patent-free.
(To the best of my knowledge. I can't afford to do a full patent
search, so I can't guarantee this. Caveat emptor).
So you can use it for whatever you like. Naturally, the source code
is part of the distribution.
Julian Seward has written bzip2
in a very portable way, so I was able to
take the source and compile it applying only small modifications which
were necessary to adapt it to the used compiler (EMX gcc) and to
OS/2 in general.
You are strongly encouraged to get the source-distribution from its
