Joseph,

You will get much more help on this list if you show us what you have actually
tried so far to solve the problem on your own. Then post what is not working
(with full tracebacks if there are any) and you will find that people will try
to assist you. If you require help reading lines from a file or learning
regular expressions, you really need to use Google to look for tutorials first.
