longDescription =
''gzip (GNU zip) is a popular data compression program written by
Jean-loup Gailly for the GNU project. Mark Adler wrote the
decompression part.
We developed this program as a replacement for compress because of
the Unisys and IBM patents covering the LZW algorithm used by
compress. These patents made it impossible for us to use compress,
and we needed a replacement. The superior compression ratio of gzip
is just a bonus.
