Change of language.

[TorB]

Hello.
First off all, thanks for providing this excellent script for free. What a job. Installed it a few days ago and it's running perfect. Excellent documentation.
A few questions:
Is it easy to change language to e.q norwegian? In which folder or what files do I have to change? I only want to change the files displayed on the net.
If I change these files, will it than be a problem to upgrade to a newer version?
What kind of file is e.q rosamunde_frame.xar?
Thanks again :-)
