simple, composable, and easy-to-use stream IO

 io-streams library comes with functions to use files, handles, concurrent
 channels, sockets, lists, vectors, and more as streams. It also has a
 variety of combinators for wrapping and transforming streams, including
 compression and decompression using zlib, controlling precisely how many
 bytes are read from or written to a stream, buffering output using
 bytestring builders, folds, maps, filters, zips, etc.
 .
 io-streams library provides support for parsing from streams using
 attoparsec, and for spawning processes and communicating with them using
 streams.
 .
 This package provides a library for the Haskell programming language.
