		142
		143	=head2 ATTACHABLE OBJECTS
		144
		145	Many objects in crossfire are so-called attachable objects. That means you can
		146	attach callbacks/event handlers (a collection of which is called an "attachment")
		147	to it. All such attachable objects support the following methods.
		148
		149	In the following description, CLASS can be any of C<global>, C<object>
		150	C<player>, C<client> or C<map> (i.e. the attachable objects in
		151	crossfire+).
		152
		153	=over 4
		154
		155	=item $attachable->attach ($attachment, key => $value...)
		156
		157	=item $attachable->detach ($attachment)
		158
		159	Attach/detach a pre-registered attachment to a specific object and give it
		160	the specified key/value pairs as arguments.
		161
		162	Example, attach a minesweeper attachment to the given object, making it a
		163	10x10 minesweeper game:
		164
		165	$obj->attach (minesweeper => width => 10, height => 10);
		166
		167	=item $bool = $attachable->attached ($name)
		168
		169	Checks wether the named attachment is currently attached to the object.
		170
		171	=item cf::CLASS->attach ...
		172
		173	=item cf::CLASS->detach ...
		174
		175	Define an anonymous attachment and attach it to all objects of the given
		176	CLASS. See the next function for an explanation of its arguments.
		177
		178	You can attach to global events by using the C<cf::global> class.
		179
		180	Example, log all player logins:
		181
		182	cf::player->attach (
		183	on_login => sub {
		184	my ($pl) = @_;
		185	...
		186	},
		187	);
		188
		189	Example, attach to the jeweler skill:
		190
		191	cf::object->attach (
		192	type => cf::SKILL,
		193	subtype => cf::SK_JEWELER,
		194	on_use_skill => sub {
		195	my ($sk, $ob, $part, $dir, $msg) = @_;
		196	...
		197	},
		198	);
		199
		200	=item cf::CLASS::attachment $name, ...
		201
		202	Register an attachment by C<$name> through which attachable objects of the
		203	given CLASS can refer to this attachment.
		204
		205	Some classes such as crossfire maps and objects can specify attachments
		206	that are attached at load/instantiate time, thus the need for a name.
		207
		208	These calls expect any number of the following handler/hook descriptions:
		209
		210	=over 4
		211
		212	=item prio => $number
		213
		214	Set the priority for all following handlers/hooks (unless overwritten
		215	by another C<prio> setting). Lower priority handlers get executed
		216	earlier. The default priority is C<0>, and many built-in handlers are
		217	registered at priority C<-1000>, so lower priorities should not be used
		218	unless you know what you are doing.
		219
		220	=item type => $type
		221
		222	(Only for C<< cf::object->attach >> calls), limits the attachment to the
		223	given type of objects only (the additional parameter C<subtype> can be
		224	used to further limit to the given subtype).
		225
		226	=item on_I<event> => \&cb
		227
		228	Call the given code reference whenever the named event happens (event is
		229	something like C<instantiate>, C<apply>, C<use_skill> and so on, and which
		230	handlers are recognised generally depends on the type of object these
		231	handlers attach to).
		232
		233	See F<include/eventinc.h> for the full list of events supported, and their
		234	class.
		235
		236	=item package => package::
		237
		238	Look for sub functions of the name C<< on_I<event> >> in the given
		239	package and register them. Only handlers for eevents supported by the
		240	object/class are recognised.
		241
		242	=back
		243
		244	Example, define an attachment called "sockpuppet" that calls the given
		245	event handler when a monster attacks:
		246
		247	cf::object::attachment sockpuppet =>
		248	on_skill_attack => sub {
		249	my ($self, $victim) = @_;
		250	...
