synopsis:        Compression and decompression in the gzip and zlib formats

description:     This package provides a pure interface for compressing and 

                 decompressing streams of data represented as lazy 

                 'ByteString's. It uses the

                 <https://en.wikipedia.org/wiki/Zlib zlib C library>

                 so it has high performance. It supports the \"zlib\",

                 \"gzip\" and \"raw\" compression formats.

                 .

                 It provides a convenient high level API suitable for most

                 tasks and for the few cases where more control is needed it

                 provides access to the full zlib feature set.

  description: The (de)compression calls can sometimes take a long time, which

               prevents other Haskell threads running. Enabling this flag

               avoids this unfairness, but with greater overall cost.
