Thank you.

I used a perl script called delirium to do that. It's a text filter that works on STDIN/STDOUT. It also uses HTML::Parser so it won't mess up your tags (just your content ;). I've put it up here at perlmonks.org, and it's also in the CVS repository for Free Software at my werk. (Just hit the link below).

Be glad that I didn't make the whole article delirious.
