On login to Ubuntu, I start an Emacs (version 23) daemon using Ubuntu's Startup programs. I then start Emacs clients whenever I need to edit something. When I logoff from Ubuntu, it says Emacs is still running, of course. I need to attach a script somewhere to tell Gnome to shutdown emacs when I logoff/shutdown. 

1) What should the script look like? "kill-emacs" doesn't seem to work. 

2) Where should I put this script? There's nothing in the startup programs (System->Sessions menu) panel that looks useful. I'd prefer something that works in the user's account, rather than hacking the PostSession script or something else with root access.
