grammar for propositional logic

[Martin McDermott]

I'm trying to write a simple grammar for propositional logic for a project
of mine, with support for AND, OR, XOR, NOT. Nothing fancy, only I cant seem
to come up with a correct grammar. My simple test cases all give me syntax
errors.

Anyone mind taking a look at it?

Thanks
Marty
