''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.
