		484
		485	In the following description, CLASS can be any of C<global>, C<object>

		513
		514	You can attach to global events by using the C<cf::global> class.
		515
		516	Example, log all player logins:
		517
		518	cf::player->attach (
		519	on_login => sub {
		520	my ($pl) = @_;
		521	...
		522	},
		523	);
		524

		527	cf::object->attach (
		528	type => cf::SKILL,
		529	subtype => cf::SK_JEWELER,
		530	on_use_skill => sub {

		532	...
		533	},
		534	);
		535
		536	=item cf::CLASS::attachment $name, ...
		537
		538	Register an attachment by C<$name> through which attachable objects of the
		539	given CLASS can refer to this attachment.
		540
		541	Some classes such as crossfire maps and objects can specify attachments
		542	that are attached at load/instantiate time, thus the need for a name.
