		133	Set the priority for all following handlers/hooks (unless overwritten

		135	earlier. The default priority is C<0>, and many built-in handlers are
		136	registered at priority C<-1000>, so lower priorities should not be used

		141	Call the given code reference whenever the named event happens (event is
		142	something like C<instantiate>, C<apply>, C<use_skill> and so on, and which
		143	handlers are recognised generally depends on the type of object these

		158
		159	Attach handlers for a specific object type (e.g. TRANSPORT) and

		161	type.
		162
		163	=item cf::attach_to_objects ...
		164
		165	Attach handlers to all objects. Do not use this except for debugging or

		167	the game.
