28 ''gzip (GNU zip) is a popular data compression program written by
29 Jean-loup Gailly for the GNU project. Mark Adler wrote the
30 decompression part.
31
32 We developed this program as a replacement for compress because of
33 the Unisys and IBM patents covering the LZW algorithm used by
34 compress. These patents made it impossible for us to use compress,
35 and we needed a replacement. The superior compression ratio of gzip
36 is just a bonus.
