		153
		154	Many objects in crossfire are so-called attachable objects. That means you can
		155	attach callbacks/event handlers (a collection of which is called an "attachment")
		156	to it. All such attachable objects support the following methods.
		157
		158	In the following description, CLASS can be any of C<global>, C<object>
		159	C<player>, C<client> or C<map> (i.e. the attachable objects in

		187	You can attach to global events by using the C<cf::global> class.

		193	my ($pl) = @_;
		194	...
		195	},
