The xz command is a program for compressing files.
* Average compression ratio of LZMA is about 30% better than that of gzip, and 15% better than that of bzip2.
* Decompression speed is only little slower than that of gzip, being two to five times faster than bzip2.
* In fast mode, compresses faster than bzip2 with a comparable compression ratio.
* Achieving the best compression ratios takes four to even twelve times longer than with bzip2. However, this does not affect decompressing speed.
* Very similar command line interface to what gzip and bzip2 have.
