Honestly, you are going to have some difficulty with this, especially if you are looking to have one script served in multiple language all pieced together from around the place. If you are serious about translation of content, you should hire someone to do it. This is the best route to go.
NameNick, I don't know of any, but I'd just ask whoever localized your scripts. They'd atleast know what to search for and who a script directory would be called in their language.
This is an english only forum. Odds are you aren't going to get much help in this area.
