+/**
+ * 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()
