changing default enlightenment for all users?

["David Nellans" <dave cs colgate edu>]

i can manually change what enlightenment install to use through gnome
control center, so that exec gnome session starts up with proper gnome items
and window manager, however i'd like to change the default gnome setting to
use this new version as well.  what config file is this hidden in?

thanks very much for all the help
