arabic docbuilds

Hi, Does anyone have an idea on why the Arabic builds are only half done? I mean http://www.php.net/manual/ar/preface.php works as a lot of other pages, but http://www.php.net/manual/ar/ only displays a directory index, since there is no manual index generated. This is why this language is not listed among the available ones. The files on the server are quite actual (july 17, 2004), so it was built recently. Derick, do you have a clue? Goba
