Summary     : library for compression and decompression
Description :
zlib is designed to be a free, general-purpose, legally unencumbered
-- that is, not covered by any patents -- lossless data-compression
library for use on virtually any computer hardware and operating
system. The zlib data format is itself portable across
platforms. Unlike the LZW compression method 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 in compression. A more precise, technical discussion of both
points is available on another page.
