If these are the pretenses we are operating under, then the very first reply in this thread answers the question. I think the only reason that the thread reached 15 pages is because the pretenses weren't well-defined enough. I apologize for assuming that mine were "right", but they were based on what I thought the OP was asking for. It's really up to him (and anyone who is asking themselves this question) to decide which of the answers given is right.
