+Lzip is a lossless data compressor with a user interface similar to the
+one of gzip or bzip2. Lzip can compress about as fast as gzip (lzip -0)
+or compress most files more than bzip2 (lzip -9). 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.
