used in Unix compress(1) and in the GIF image format, the compression method

currently used in zlib essentially never expands the data. (LZW can double or

triple the file size in extreme cases.) zlib's memory footprint is also

independent of the input data and can be reduced, if necessary, at some cost

Gailly for the GNU project. Mark Adler wrote the decompression part.

We developed this program as a replacement for compress because of the Unisys

made it impossible for us to use compress, and we needed a replacement. The
|

superior compression ratio of gzip is just a bonus.")
