NAME

       lz4c - Tool using Fast LZ compression algorithm library

SYNOPSIS

       lz4c [options] file ...

DESCRIPTION

       LZ4   is  a  very  fast  lossless  compression  algorithm.   This  uses
       Dictionary compression, and only supports compression and decompression
       unit blocks.

       Infomation  about  compression  ratio  and speed (from webpage of lz4):
       single thread, Core  2  Duo  @3GHz,  using  the  Open-Source  Benchmark
       program by m^2 compiled with GCC v4.5.2, on the Silesia Corpus.
