+ * \file bell.h Ring the bell or flash the screen
+ *
+ * Sometimes, X programs "ring the bell", whatever that means. Mutter lets
+ * the user configure the bell to be audible or visible (aka visual), and
+ * if it's visual it can be configured to be frame-flash or fullscreen-flash.
+ * We never get told about audible bells; X handles them just fine by itself.
+ *
+ * The visual bell was the result of a discussion in Bugzilla here:
+ * <http://bugzilla.gnome.org/show_bug.cgi?id=99886>.
