      lzip - reduces the size of files

      lzip [,options/] [,files/]

      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, chosen to
      maximize safety and interoperability. 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

      If no file names are given, or if a file is '-', lzip compresses or
      decompresses from standard input to standard output.  Numbers may be
      followed by a multiplier: k = kB = 10^3 = 1000, Ki = KiB = 2^10 =
      1024, M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc...  Dictionary
      sizes 12 to 29 are interpreted as powers of two, meaning 2^12 to 2^29

      The bidimensional parameter space of LZMA can't be mapped to a linear
      scale optimal for all files. If your files are large, very repetitive,
      etc, you may need to use the options --dictionary-size and
      --match-length directly to achieve optimal performance.

      To extract all the files from archive 'foo.tar.lz', use the commands
      'tar -xf foo.tar.lz' or 'lzip -cd foo.tar.lz | tar -xf -'.

      not found, invalid flags, I/O errors, etc), 2 to indicate a corrupt or
      invalid input file, 3 for an internal consistency error (eg, bug)
      which caused lzip to panic.

      The ideas embodied in lzip are due to (at least) the following people:
      Abraham Lempel and Jacob Ziv (for the LZ algorithm), Andrey Markov
      (for the definition of Markov chains), G.N.N. Martin (for the
      definition of range encoding), Igor Pavlov (for putting all the above
      together in LZMA), and Julian Seward (for bzip2's CLI).
