gzip - gnu zip and unzip compression program.

gzip is a compress/decompress program distributed under the GNU license.
This is a DOS version of gzip.  To decompress a file, type

 C:\>gzip -d <filename>

For help type:

 C:\>gzip -h

gzip does not archive programs.  In other words, you cannot combine
several programs into one compressed archive as you can with pkzip.
