+to decompress files but don't need compression capabilities.
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 to maximize interoperability. The
-maximum dictionary size is 512 MiB so that any lzip file can be decompressed
-on 32-bit machines. Lzip provides accurate and robust 3-factor integrity
-checking. 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
