Oh! There's a handful of modules that aren't yet available in 3.x,
which might surprise someone who's moving from 2.x. But hey, I didn't
know about difflib (although I probably would have found it if I'd
gone searching). Python has more than expected, not less!

And Zachary: You're most welcome. Glad to have been of service!
