+At this writing this mechanism is used only for event handling.
+Three events are available. Two events relate to TAP enabling
+and disabling, one to post reset handling.
 
 The @code{configure} subcommand assigns an event handler,
 a TCL string which is evaluated when the event is triggered.
 The @code{cget} subcommand returns that handler.
-The two possible values for an event @var{name}
