#This program runs a custom command/script just before gnome shuts
#down. This is done the same way that gedit does it (listening for
#the 'save-yourself' event).  This is different to placing scipts
#in /etc/rc#.d/ as the script will be run before gnome exits.
#If the custom script/command fails with a non-zero return code, a
#popup dialog box will appear offering the chance to cancel logout
#
#Usage: 1 - change the command in the 'subprocess.call' in
#           function 'session_save_yourself' below to be what ever
#           you want to run at logout.
#       2 - Run this program at every gnome login (add via menu System
#           -> Preferences -> Session)
