Wow, that's really nice. Thanks for sharing that. I think we should aim
to get to a point where org-mode can produce such nicely formatted
source code out-of-the-box. Maybe we could even make latex inherit the
colours and fonts that emacs is currently using for source code mark up?
I was going to suggest doing this with listings but then came across
minted, and I wonder whether that's even more suitable? (See the other
post I just made.)
