Description: PPM (Prediction by Partial Match) is a classic compression
algorithm. PPM predicts the probability of a given character based on the
characters that immediately precede it (see also Markov Chains and Context
Modeling). PPMZ is an efficient version of PPM that uses. PPMZ2 is Charles
Bloom's (the author of PPMZ) next version of PPMZ. This archiver should be
better than gzip, bzip2, and zip at compressing files.
