The io-streams library contains simple and easy-to-use primitives for I/O
using streams. Most users will want to import the top-level convenience
module System.IO.Streams, which re-exports most of the library:

import System.IO.Streams (InputStream, OutputStream)
import qualified System.IO.Streams as Streams

For first-time users, io-streams comes with an included tutorial, which can
be found in the System.IO.Streams.Tutorial module.
