You're probably right that I should have looked into it. But seeing as
the HTML export of code is so nice and requred no configuration, I never
got round to it. Although I did write my Ph.D. in latex, and I am
enjoying using the listings package for formatting pseudocode in a paper
which I'm supposed to be writing, I do need to become better friends
with latex, it's true.

Usage of listings is controlled by the variable
`org-export-latex-listings', so the simplest start would be: if that is
non-nil then code like yours could be inserted into the latex output.

Hey, I never said that! :) 

I said it might be better *for export of code from org-mode*. But
seriously, no problem, in addition to my character assassination, from
what I could make out they made lots of good points. Although I will
watch out now if I come across any francophones who look like they might
be tex enthusiasts (wouldn't one always...)

What I meant is that seeing as org-users who set
`org-export-latex-listings' get black and white code with ugly fonts by
default, there are two improvement options for us:

1. we work on incorporating nice listings configuration into org mode so
   that Org users get nice colours and fonts by default
2. we add an option to allow Org users to use the minted package, which
   gives them nice colours and fonts automatically.

(2) was easy and so I did it straight away. And (1) is still something
we want to do, not least because listings is in standard latex
distributions and doesn't have an extra python requirement. Assuming
that minted/pygments are stable software that will be around for a
while, I would vote for both options ultimately being available in

Excellent, I think that will be a good addition to org-mode.
