Just go to Help / About and change the "Language" 
selection :)

There isn't any multilingual documentation yet, 
however, mainly due to great maintenance problems 
(handling 14 different languages and synchronizing all 
translators is a little bit tricky, and it would be 
much more tricky to do so with the documentation :) )
