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