%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.
