As the subject says. A couple of things you might care about:

* There is only support for selecting/installing one language. Limited,
yes, but so is text mode. Someone can file a bug if they want the ability
to add more. Or, you know, do a graphical or ks installation.

* This only affects the language of the installed system. The installer
itself will still be displayed in English.

* Only English names for languages and locales are displayed.

Resolves: rhbz#1000326
