[O] Dumb question for beamer in org mode

[Erich Neuwirth]

I am writing my first presentation in org mode for beamer.
I cannot find a way of replacing the word "outline" 
(which is used on the automatically created toc slide)
with a German word.

I am using
#+LATEX_HEADER: \usepackage[ngerman]{babel} 
but m guess is that the word "outline" is added by org, not by LeTeX.

Can anybody help?
