%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.
