Chatting on the irc channel, found out that the current index page source is at
http://cvs.openacs.org/cvs/openacs.org-dev/www/templates/homepage-new-index.adp
All the bits are called from the widgets directory. Getting closer to seeing how it's all tied together. The index.tcl is an etp reference only - how can one see the code for the page that's in the etp repository?
