bzip2/bzlib: elj compression interface


This is the elj interface to the bzip2/bzlib version 1.0 of 21 March 2000.

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 (the PPM family of statistical compressors), whilst being around twice as fast at compression and six times faster at decompression.


Documentation for the moment is limited to the source code:

and an example:

Note: For win32 users we provide the appropriate dll (bzip2.dll) and lib (bzip2.lib) files to work with the bzip2 interface:

For Linux users (for the moment), you will need to download bzip2 and compile for your system (alternatively it may already be configured to your system).
