		210	Many objects in crossfire are so-called attachable objects. That means you can

		212	to it. All such attachable objects support the following methods.
		213
		214	In the following description, CLASS can be any of C<global>, C<object>
		215	C<player>, C<client> or C<map> (i.e. the attachable objects in
