 Lzip is a lossless data compressor with a user interface similar to the one
 of gzip or bzip2. Lzip uses a simplified form of the 'Lempel\-Ziv\-Markov
-chain\-Algorithm' (LZMA) stream format and provides a 3 factor integrity
-checking to maximize interoperability and optimize safety. Lzip can compress
-about as fast as gzip (lzip \fB\-0\fR) or compress most files more than bzip2
-(lzip \fB\-9\fR). Decompression speed is intermediate between gzip and bzip2.
-Lzip is better than gzip and bzip2 from a data recovery perspective. Lzip
-has been designed, written, and tested with great care to replace gzip and
-bzip2 as the standard general\-purpose compressed format for unix\-like
-systems.
