It might help if you explain what sort of actual things that the user does
wrong that you are talking about. From where I'm sitting, the only thing I
can see that the user could do wrong is specify the wrong file. That doesn't
sound like an EnvironmentError to me, but I don't know that it should be a
ValueError or TypeError either.
