		112	Attach a pre-registered attachment to an object.

		120	Attach a pre-registered attachment to a map.

		123
		124	Attach handlers for global events.
		125
		126	This and all following C<attach_*>-functions expect any number of the
		127	following handler/hook descriptions:
		128
		129	=over 4
		130
		131	=item prio => $number
		132
		133	Set the priority for all following handlers/hooks (unless overwritten
		134	by another C<prio> setting). Lower priority handlers get executed
		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).
		145
		146	See F<include/eventinc.h> for the full list of events supported, and their
		147	class.
		148
		149	=item package => package::
		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 ...

		171	Attach handlers to all players.
