Installing matlab mode under Windows XP

[address@hidden]

Hi

I would like to install other packages like Matlab mode for emacs 
on Windows XP. Where do I have to put these additional package files? 
Is there something like the .emacs file under UNIX that tells emacs 
to load these packages? Or in other words: What do I need to do, to 
make emacs load the additional package files?

Thanks for your help.
Regards
Pascal
