		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+).

		178	You can attach to global events by using the C<cf::global> class.
		179

		183	on_login => sub {
		184	my ($pl) = @_;
		185	...
		186	},

		188

		192	type => cf::SKILL,
		193	subtype => cf::SK_JEWELER,
		194	on_use_skill => sub {

		202	Register an attachment by C<$name> through which attachable objects of the
