51 | "zlib is designed to be a free, general-purpose, legally unencumbered -- | |
52 | that is, not covered by any patents -- lossless data-compression library for | |
53 | use on virtually any computer hardware and operating system. The zlib data | |
54 | format is itself portable across platforms. Unlike the LZW compression method | |
55 | used in Unix compress(1) and in the GIF image format, the compression method | |
56 | currently used in zlib essentially never expands the data. (LZW can double or | |
57 | triple the file size in extreme cases.) zlib's memory footprint is also | |
58 | independent of the input data and can be reduced, if necessary, at some cost | |
59 | in compression.") | |
