Is there a proof calculator for basic symbolic logic? This just came to mind while I was messing around on Wolfram Alpha. The thing solves algebra, and basic symbolic logic uses, well, I don't want to say the same sort of symbol manipulation because the overlap is imperfect, but both proofs and algebra work by manipulating symbols via a set of well-defined rules.
