+ GTK+ uses this environment variable to provide startup notification
+ according to the <ulink url="http://standards.freedesktop.org/startup-notification-spec/startup-notification-latest.txt">Startup Notification Spec</ulink>.
+ Following the specification, GTK+ unsets this variable after reading
+ it (to keep it from leaking to child processes). So, if you need its
+ value for your own purposes, you have to read it before calling
+ gtk_init().
