Long Range ZIP is a compression program that can achieve very high compression ratios and speed when used with large files. It uses the combined compression algorithms of 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.

What's New in This Release:
Blocks to be compressed by lzma are now scanned by lzo in advance to find incompressible data and bypass attempting to compress them.
This speeds up substantially attempting to compress incompressible files, and should fix the "lzma getting stuck on an incompressible block" bug.
Basic Darwin support was added.
Compression mode was stratified for lower levels of lzma compression.
