xft xemacs & x resources

some questions, related by my desire of using the latest beta and the xft branch as coexisting alternatives 0. is it possible to specify to configure the name of the executable to be installed? 1. is it possible to somehow differentiate the resources used by xemacs and the resources used by the xft branch? 2. so far, so good: 21.5b19 installs the core lisp into its own hierarchy, and the xft branch installs its core lisp under a different (b18) tree when xft will receive the status of b19, is there the potential for a conflict? thank you, gb
