How to add a language to a project i Gnome svn

["Kenneth Nielsen" <k nielsen81 gmail com>]

Hello everybody
I have just gotten my svn account and have been reading to try and understand how it all works and it is going very well now. There is one thing that I have not been able to figure out though and so I was hoping that some of you might be able to help me.
For some reason the Danish translation of gnome-power-manager was lost somewhere along the change of development from gnome 2-18 to 2.20. So now my question is how do I add this translation again?
I have figured out how to add the file with svn. But besides that I figured that I would probably have to edit some files also to let the module know that there is a Danish translation. I have been looking around and it seem that the file LINGUAS in the po directory contain a list of languages. So my question is, besides adding the po-file, is the LINGUAS file the one I should edit and are there any other that I'll need to edit in order to make it work.
Thanks in advance
Regards Kenneth Nielsen
