110=item $object->attach ($attachment, key => $value...)
111
112=item $object->detach ($attachment)
113
114Attach/detach a pre-registered attachment to an object.
115
116=item $player->attach ($attachment, key => $value...)
117
118=item $player->detach ($attachment)
119
120Attach/detach a pre-registered attachment to a player.
121
122=item $map->attach ($attachment, key => $value...)
123
124=item $map->detach ($attachment)
125
126Attach/detach a pre-registered attachment to a map.
127
128=item cf::attach_global ...
129
130Attach handlers for global events.
131
132This and all following C<attach_*>-functions expect any number of the
133following handler/hook descriptions:
134
135=over 4
136
137=item prio => $number
138
139Set the priority for all following handlers/hooks (unless overwritten
140by another C<prio> setting). Lower priority handlers get executed
141earlier. The default priority is C<0>, and many built-in handlers are
142registered at priority C<-1000>, so lower priorities should not be used
143unless you know what you are doing.
144
145=item on_I<event> => \&cb
146
147Call the given code reference whenever the named event happens (event is
148something like C<instantiate>, C<apply>, C<use_skill> and so on, and which
149handlers are recognised generally depends on the type of object these
150handlers attach to).
151
152See F<include/eventinc.h> for the full list of events supported, and their
153class.
154
155=item package => package::
156
157Look for sub functions of the name C<< on_I<event> >> in the given
158package and register them. Only handlers for eevents supported by the
159object/class are recognised.
160
161=back
162
163=item cf::attach_to_type $object_type, $subtype, ...
164
165Attach handlers for a specific object type (e.g. TRANSPORT) and
166subtype. If C<$subtype> is zero or undef, matches all objects of the given
167type.
168
169=item cf::attach_to_objects ...
170
171Attach handlers to all objects. Do not use this except for debugging or
172very rare events, as handlers are (obviously) called for I<all> objects in
173the game.
174
175=item cf::attach_to_players ...
176
177Attach handlers to all players.
178
179=item cf::attach_to_maps ...
180
181Attach handlers to all maps.
182
183=item cf:register_attachment $name, ...
184
185Register an attachment by name through which objects can refer to this
186attachment.
187
188=item cf:register_map_attachment $name, ...
189
190Register an attachment by name through which maps can refer to this
191attachment.
