a readFile problem

[Hal Daume III]

It would probably be helpful if you were to post the code you have and
explain what part isn't working.  There's a function:

  readFile :: FilePath -> IO String
  (FilePath is just a String)

which reads a file.  This should be what you need to solve this
exercise...
