      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 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

      -h, --help

      -o, --output=<file>
           if reading standard input, write to <file>

      -q, --quiet
           suppress all messages

      -s, --dictionary-size=<bytes>
           set dictionary size limit in bytes [8 MiB]

      -S, --volume-size=<bytes>
           set volume size limit in bytes

      -t, --test
           test compressed file integrity

      -v, --verbose
           be verbose (a 2nd -v gives more)

      -0 .. -9
           set compression level [default 6]

           alias for -0

           alias for -9

           allow trailing data seeming corrupt header

      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 --dictionary-size and --match-length
      options directly to achieve optimal performance.

      Exit status: 0 for a normal exit, 1 for environmental problems (file
      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.
