Hello,
I started a page at Metawikipedia to let users without access to the CVS easily edit the locale files (LanguageXx.php) and maybe also start to localize Wikipedia in other languages. http://meta.wikipedia.org/wiki/Locales_for_the_Wikipedia_Software
I posted the files in iso-latin, maybe someone with a more UTF-8 friendly system could add the others - I fear to destroy special characters.
greetings, elian PS: Is the languages Array really necessary in every locale? I thought language names should be always the native ones.
