[stack] Cat Wikipedia Article

I'd appreciate a few eyes on the recently created Wikipedia article on
Cat ( http://en.wikipedia.org/wiki/Cat_%28programming_language%29 ). I
talk a lot about Joy, and I want to make sure that I am not
misrepresenting it at all.

Being Wikipedia, you can of course go ahead and make changes that you
think are appropriate. If you are unsure you can always make a
suggestion on the talk page.

Thanks,
Christopher
