`xtexit` sends an request to all clients to shut down. If the application still needs an user interaction (e.g., if a file should be saved) this is possible. If you answer by the affirmative, all applications will be closed. This method is not fully waterproof, but better than killing each and every client without being able to interfere. xterm applications anyway are killed immediately!

If this package is installed, it will be automatically integrated into the sample user fvwm menu.
