Rolling my own browser

[CORONA,FATIMA (HP-Boise,ex1)]

I am looking at the page
http://www.mozilla.org/projects/embedding/howto/initializations.html
and from what I understood. The two functions you give:

nsresult NS_InitEmbedding(const char *aPath); 
nsresult NS_TermEmbedding(); 
do I just place them on my newly created package, so it can be linked to the
rest of mozilla ?
any special formatting ?
Will this do the rest for me? or do I still need xtra code in order to take
care of XPCOM and NS InitXPCOM?

Thanks,
Fatima
