The Lempel-Ziv-Markov chain-Algorithm (LZMA) is an algorithm which allows you to compress files immensely by using hours of raw CPU-power while allocating half your systems memory to gain a minor compression ratio increase over bzip2.

[edit] Modern use

The Novell corporation is using it for their own evil purposes and they even brag that they are going to an mass hurd the SUSE Linux users "to LZMA for the RPM payload".

[edit] Usage

with tar:

tar cfva archive.tar.lzma folder1/ folder2/

[edit] Technology

Paul Sladen has this to say about our ace algorithm:

"LZMA is effectively deflate (zlib, gzip, zip) with a larger dictionary size, 32MB instead of 32kB. LZMA stands for Lempel-Ziv-Markov chain-Algorithm, after string back-references have been located, values are reduced using a Markov chain range-encoder (aka arithmetic coding) instead of huffman.[1]"
