aanund / Denumbering

I'm seeking to set up a script that will take away line numbering from programming examples found on sites and in books. should be fairly easy, many sites now offer "toggle" to get rid of line numbers. but if you're looking at an pdf ebook in programming, that is not an option. Another thing all together is the potential distortion of relative indentation within the python script. I'll have to look at that in a separate project
