Here's a howto:
    http://www.haskell.org/hawiki/BinaryIo

Look for the instance Binary  code. That's where you set up your binary
parsers for each Haskell type. lso, these day,s you can do a fair bit of
binary hacking with Data.ByteString, without the Binary class layer over
the top.  Hope that helps.
