[AUCTeX] Problem with German quotes

[Lucas Holland]

Hello all,

according to the manual (section 4.1) AucTeX will recognise statements like 
\usepackage[ngerman]{babel} and automatically insert the right quotes (i. e. "` 
and "’ ). This doesn’t work for me with the following setup: 

I have a master document that uses a custom package (like so: 
\usepackage{mypackage}). In that package I include all the packages I use in my 
document among them \usepackage[ngerman]{babel}. I have 

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:

at the end of my master file and 

%%% Local Variables: 
%%% mode: latex
%%% TeX-master: "../masterfile"
%%% End: 

in my custom package file (.sty file). 

Is there a way I can make AuCTeX recognise that I’m using the babel package 
with the ngerman option so that it automatically uses the right quotes? 

Thanks!
