This is NOT a help request (my previous thread gave that wrong impression, so today I make the precision clearly), but rather, I'm suggesting something that, in my eyes, would make wordpress better :)
In short, I'd very much like to suggest that the installation of a non-English version of wordpress via subversion could be explained in simple terms in the Codex.
At the present time, the page http://codex.wordpress.org/Installing/Updating_WordPress_with_Subversion only concerns English installations of wordress.
I saw various people trying to install French or other versions of WordPress with subversion, but few of them succeeded, and every time it was an old or incomplete page.
I think this is something that could be improved :)
I'm sorry I can't contribute myself with such a page, not even a draft (and yet, I know I may look like a dick to suggest something I can't do), but I really believe this is a dark side of Worpdpress, that would make wordpress better if it was made clearer.
