/** ActionGroup - a group of actions.
 * ActionGroup represents a group of actions.
 *
 * Each action in the group has a unique name (which is a string). All method
 * calls, except 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 -- get_action_enabled() but not an equivalent @c set() call.
 *
 * Signals are emitted on the action group in response to state changes on
 * individual actions.
