     NAME
          minilzip - reduces the size of files

     SYNOPSIS
          minilzip [,options/] [,files/]

     DESCRIPTION
          Minilzip is a test program for the compression library lzlib, fully
          compatible with lzip 1.4 or newer.

          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
          systems.

                                    January 2021

          -m, --match-length=<bytes>
               set match length limit in bytes [36]

          -o, --output=<file>
               write to <file>, keep input files

          -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]

          --fast
               alias for -0

          --best
               alias for -9

          --loose-trailing
               allow trailing data seeming corrupt header

          --check-lib
               compare version of lzlib.h with liblz.{a,so}

          If no file names are given, or if a file is '-', minilzip 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
          bytes.

          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

     User Commands                                                 User Commands

          'tar -xf foo.tar.lz' or 'minilzip -cd foo.tar.lz | tar -xf -'.

          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 minilzip to panic.

          The ideas embodied in lzlib 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).
