+ "This package provides a pure interface for compressing and decompressing
+streams of data represented as lazy 'ByteString's. 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.")
