Hi everybody,

I've been using org-mode for quite a while but only recently found
myself in need of using ditaa to draw some simple diagram. As it turns
out my installation of emacs(Ubuntu 10.10, emacs-snapshot from
https://launchpad.net/~cassou/+archive/emacs) doesn't come with
ditta.jar pre-bundled, although I'm not sure if it should. Anyway, despite
my installation of ditta with help of apt-get, org-babel kept
unsuccessfully trying to locate
/usr/share/emacs/24.0.91/lisp/contrib/ditta.jar, leaving me without any
diagrams produced.

So to alleviate the problem I cloned git repository and wrote a small
patch implementing very crude algorithm, which is, nonetheless, in my
opinion, still an improvement on default behavior. For more details see
commit message.
