A compression program that can achieve very high compression
ratios and speed when used with large files. It uses the combined
compression algorithms of zpaq and lzma for maximum compression, lzo
for maximum speed, and the long range redundancy reduction of rzip.
It is designed to scale with increases with RAM size, improving
compression further. A choice of either size or speed optimizations
allows for either better compression than even lzma can provide, or
better speed than gzip, but with bzip2 sized compression levels.
