111		144
112	=item $object->detach ($attachment)	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.
113		148
114	Attach/detach a pre-registered attachment to an object.	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+).

123		156
124	=item $map->detach ($attachment)	157	=item $attachable->detach ($attachment)
125		158
126	Attach/detach a pre-registered attachment to a map.	159	Attach/detach a pre-registered attachment to a specific object and give it
		160	the specified key/value pairs as arguments.
127		161
128	=item cf::attach_global ...	162	Example, attach a minesweeper attachment to the given object, making it a
		163	10x10 minesweeper game:
129		164
130	Attach handlers for global events.	165	$obj->attach (minesweeper => width => 10, height => 10);
131		166
132	This and all following C<attach_*>-functions expect any number of the	167	=item $bool = $attachable->attached ($name)
133	following handler/hook descriptions:	168

		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
