General ⇒ Running Draft Counter on a Page

[tofergregg]

I'm wondering how I might go about putting a "Draft #" on the top of my LaTeX documents that gets updated every time I recompile. I'm working on a bash solution through my Makefile (1. create a PDF that has the draft text and 2. merge it onto the first page), but I figure there might be an easier all-LaTeX way to do it. Thanks!
