- * Declare triggers (events) for users to assign actions to.
- *
- * This hook is used by the trigger module to create a list of triggers (events)
- * that users can assign actions to. Your module is responsible for detecting
- * that the events have occurred, calling trigger_get_assigned_actions() to find
- * out which actions the user has associated with your trigger, and then calling
- * actions_do() to fire off the actions.
- *
- * @return
- * A nested associative array.
- * - The outermost key is the name of the module that is defining the triggers.
- * This will be used to create a local task (tab) in the trigger module's
- * user interface. A contrib module may supply a trigger for a core module by
- * giving the core module's name as the key. For example, you could use the
- * 'node' key to add a node-related trigger.
- * - Within each module, each individual trigger is keyed by a hook name
- * describing the particular trigger (this is not visible to the user, but
- * can be used by your module for identification).
- * - Each trigger is described by an associative array. Currently, the only
- * key-value pair is 'label', which contains a translated human-readable
- * description of the triggering event.
- * For example, the trigger set for the 'node' module has 'node' as the
- * outermost key and defines triggers for 'node_insert', 'node_update',
- * 'node_delete' etc. that fire when a node is saved, updated, etc.
- *
- * @see hook_action_info()
- * @see hook_trigger_info_alter()
