The site.vm was working fine... until you went and started changing  
things :-P  I made several changes so that the generated sites looked  
like the geronimo site.

Its a custom skin and IMO should not need to be compared to the  
default skin at all.  I just based our skin on the default skin, thats

I don't generally need to diff files of this nature... and I'm still  
confused why you are trying to do it.  I understand that something  
changed and now its broke.  So I suggest reverting your changes, or re- 
crafting the site.vm from the default so that it looks & behaves the  
same.  If you want to leave that file 2 space indent I don't care, but  
thats no reason to change everything to 2 spaces.
