		124	Attach handlers for global events.

		132
		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
		137	unless you know what you are doing.
		138
		139	=item on_I<event> => \&cb
		140
		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
		144	handlers attach to).

		147	class.
		148

		150
		151	Look for sub functions of the name C<< on_I<event> >> in the given
		152	package and register them. Only handlers for eevents supported by the
		153	object/class are recognised.
		154
		155	=back
		156
		157	=item cf::attach_to_type $object_type, $subtype, ...
		158
		159	Attach handlers for a specific object type (e.g. TRANSPORT) and
		160	subtype. If C<$subtype> is zero or undef, matches all objects of the given
		161	type.
		162
		163	=item cf::attach_to_objects ...
		164
		165	Attach handlers to all objects. Do not use this except for debugging or
		166	very rare events, as handlers are (obviously) called for I<all> objects in
		167	the game.
		168
		169	=item cf::attach_to_players ...
