  gzip
       
           {GNU} compression utility.  Gzip reduces
          the size of the named files using {Lempel-Ziv} {LZ77
          compression}.  Whenever possible, each file is replaced by one
          with the {filename extension} ".gz".  Compressed files can be


          restored to their original form using gzip -d or gunzip or
          zcat.
       
          The Unix "{compress}" utility is patented (by two separate
          patents, in fact) and is thus shunned by the GNU Project since
          it is not {free software}.  They have therefore chosen gzip,
          which is free of any known {software patent}s and which tends
          to compress better anyway.  All compressed files in the {GNU}
          {anonymous FTP} area (gnu.org/pub/gnu) are in gzip
          format and their names end in ".gz" (as opposed to
          "compress"-compressed files, which end in ".Z").
       
          Gzip can uncompress "compress"-compressed files and "pack"
          files (which end in ".z").  The decompression algorithms are
          not patented, only compression is.
       
          The gzip program is available from any {GNU archive site} in
          {shar}, {tar}, or gzipped tar format (for those who already
          have a prior version of gzip and want faster data
          transmission).  It works on virtually every {Unix} system,
          {MS-DOS}, {OS/2} and {VMS}.
