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

  88 made it impossible for us to use compress, and we needed a replacement.  The
  89 superior compression ratio of gzip is just a bonus.")

 173 compression algorithm is currently LZMA2, which is used inside the .xz

 175 than gzip and 15 % smaller output than bzip2.")
