 This package provides a pure interface for compressing and decompressing
 streams of data represented as lazy ByteStrings. It uses the 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.

 This package provides the documentation for a library for the Haskell
 programming language.
