><P
>The GNOME triggers API was intended to provide a general way for the
application to tell GNOME about "interesting events". Most of it is
presently deprecated - at the present time, the application writer
should only use gnome_triggers_do and gnome_triggers_vdo for the purpose
of firing application sound events (in conjunction with .soundlist files).</P
><P
>Please see the "GNOME configuration files" white paper for more information
on .soundlist files.</P
