Language List Source
I am wanting to reuse this implementation of a language box on my Wiki, and I am wondering about the source of the language names (e.g., when Main_Page/zh is created, "中文" is added to the language list). I can see that the list of accepted ISO codes is in Template:Languages, but I can't figure out how "zh" is transformed into "中文". If I wanted to add items to that list, or modify it, how could I do that?

Any response would be greatly appreciated!


 * See Special:PrefixIndex/Template:Languages. The list of transformations is in Template:Languages/Title. —Emufarmers(T 19:59, 12 January 2011 (UTC)
