+ * @title: GActionGroup
+ * @short_description: a group of actions
+ *
+ * #GActionGroup represents a group of actions.
+ *
+ * Each action in the group has a unique name (which is a string). All
+ * method calls, except g_action_group_list_actions() take the name of
+ * an action as an argument.
+ *
+ * The #GActionGroup API is meant to be the 'public' API to the action
+ * group. The calls here are exactly the interaction that 'external
+ * forces' (eg: UI, incoming D-Bus messages, etc.) are supposed to have
+ * with actions. 'Internal' APIs (ie: ones meant only to be accessed by
+ * the action group implementation) are found on subclasses. This is
+ * why you will find -- for example -- g_action_group_get_enabled() but
+ * not an equivalent <function>set()</function> call.
+ *
+ * Signals are emitted on the action group in response to state changes
+ * on individual actions.
