108=item $object->attach ($attachment, ...)
109
110Attach a pre-registered attachment to an object.
111
112=item $player->attach ($attachment, ...)
113
114Attach a pre-registered attachment to a player.
115
116=item $map->attach ($attachment, ...) # not yet persistent
117
118Attach a pre-registered attachment to a map.
119
120=item cf::attach_global ...
121
122Attach handlers for global events.
123
124This and all following C<attach_*>-functions expect any number of the
125following handler/hook descriptions:
126
127=over 4
128
129=item prio => $number
130
131Set the priority for all following handlers/hooks (unless overwritten
132by another C<prio> setting). Lower priority handlers get executed
133earlier. The default priority is C<0>, and many built-in handlers are
134registered at priority C<-1000>, so lower priorities should not be used
135unless you know what you are doing.
136
137=item on_I<event> => \&cb
138
139Call the given code reference whenever the named event happens (event is
140something like C<instantiate>, C<apply>, C<use_skill> and so on, and which
141handlers are recognised generally depends on the type of object these
142handlers attach to).
143
144See F<include/eventinc.h> for the full list of events supported, and their
145class.
146
147=item package => package::
148
149Look for sub functions of the name C<< on_I<event> >> in the given
150package and register them. Only handlers for eevents supported by the
151object/class are recognised.
152
153=back
154
155=item cf::attach_to_type $object_type, ...
156
157Attach handlers for a specific object type (e.g. TRANSPORT).
158
159=item cf::attach_to_objects ...
160
161Attach handlers to all objects. Do not use this except for debugging or
162very rare events, as handlers are (obviously) called for I<all> objects in
163the game.
164
165=item cf::attach_to_players ...
166
167Attach handlers to all players.
168
169=item cf::attach_to_maps ...
170
171Attach handlers to all maps.
172
