		122	Attach handlers for global events.

		126
		127	=over 4
		128
		129	=item prio => $number
		130
		131	Set the priority for all following handlers/hooks (unless overwritten
		132	by another C<prio> setting). Lower priority handlers get executed
		133	earlier. The default priority is C<0>, and many built-in handlers are
		134	registered at priority C<-1000>, so lower priorities should not be used
		135	unless you know what you are doing.

		139	Call the given code reference whenever the named event happens (event is
		140	something like C<instantiate>, C<apply>, C<use_skill> and so on, and which
		141	handlers are recognised generally depends on the type of object these
		142	handlers attach to).
		143
		144	See F<include/eventinc.h> for the full list of events supported, and their
		145	class.
		146
		147	=item package => package::
		148
		149	Look for sub functions of the name C<< on_I<event> >> in the given
		150	package and register them. Only handlers for eevents supported by the
		151	object/class are recognised.
