Description:
  /Overview/
  .
  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.
  .
  /Features/
  .
  The @io-streams@ user API has two basic types: @InputStream a@ and
  @OutputStream a@, and three fundamental I/O primitives:
  .
  @
  \-\- read an item from an input stream
  Streams.read :: InputStream a -> IO (Maybe a)
  .
  \-\- push an item back to an input stream
  Streams.unRead :: a -> InputStream a -> IO ()
  .
  \-\- write to an output stream
  Streams.write :: Maybe a -> OutputStream a -> IO ()
  @
  .
  Streams can be transformed by composition and hooked together with provided combinators:
  .
  @
  ghci> Streams.fromList [1,2,3::Int] >>= Streams.map (*10) >>= Streams.toList
  [10,20,30]
  @
  .
  Stream composition leaves the original stream accessible:
  .
  @
  ghci> input \<- Streams.fromByteString \"long string\"
  ghci> wrapped \<- Streams.takeBytes 4 input
  ghci> Streams.read wrapped
  Just \"long\"
  ghci> Streams.read wrapped
  Nothing
  ghci> Streams.read input
  Just \" string\"
  @
  .
  Simple types and operations in the IO monad mean straightforward and simple
  exception handling and resource cleanup using Haskell standard library
  facilities like 'Control.Exception.bracket'.
  .
  @io-streams@ comes with:
  .
    * functions to use files, handles, concurrent channels, sockets, lists,
      vectors, and more as streams.
  .
    * 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.
  .
    * support for parsing from streams using @attoparsec@.
  .
    * support for spawning processes and communicating with them using streams.
