-/* The org.gtk.Actions interface
- * =============================
- *
- * This interface describes a group of actions.
- *
- * Each action:
- * - has a unique string name
- * - can be activated
- * - optionally has a parameter type that must be given to the activation
- * - has an enabled state that may be true or false
- * - optionally has a state which can change value, but not type
- *
- * Methods
- * -------
- *
- * List :: () → (as)
- *
- * Lists the names of the actions exported at this object path.
- *
- * Describe :: (s) → (bgav)
- *
- * Describes a single action, or a given name.
- *
- * The return value has the following components:
- * b: specifies if the action is currently enabled. This is
- * a hint that attempting to interact with the action will
- * produce no effect.
- * g: specifies the optional parameter type. If not "",
- * the string specifies the type of argument that must
- * be passed to the activation.
- * av: specifies the optional state. If not empty, the array
- * contains the current value of the state as a variant
- *
- * DescribeAll :: () → (a{s(bgav)})
- *
- * Describes all actions in a single round-trip.
- *
- * The dictionary maps action name strings to their descriptions
- * (in the format discussed above).
- *
- * Activate :: (sava{sv}) → ()
- *
- * Requests activation of the named action.
- *
- * The action is named by the first parameter (s).
- *
- * If the action activation requires a parameter then this parameter
- * must be given in the second parameter (av). If there is no parameter
- * to be specified, the array must be empty.
- *
- * The final parameter (a{sv}) is a list of "platform data".
- *
- * This method is not guaranteed to have any particular effect. The
- * implementation may take some action (including changing the state
- * of the action, if it is stateful) or it may take none at all. In
- * particular, callers should expect their request to be completely
- * ignored when the enabled flag is false (but even this is not
- * guaranteed).
- *
- * SetState :: (sva{sv}) → ()
- *
- * Requests the state of an action to be changed to the given value.
- *
- * The action is named by the first parameter (s).
- *
- * The requested new state is given in the second parameter (v).
- * It must be equal in type to the existing state.
- *
- * The final parameter (a{sv}) is a list of "platform data".
- *
- * This method is not guaranteed to have any particular effect.
- * The implementation of an action can choose to ignore the requested
- * state change, or choose to change its state to something else or
- * to trigger other side effects. In particular, callers should expect
- * their request to be completely ignored when the enabled flag is
- * false (but even this is not guaranteed).
- *
- * Signals
- * -------
- *
- * Changed :: (asa{sb}a{sv}a{s(bgav)})
- *
- * Signals that some change has occured to the action group.
- *
- * Four separate types of changes are possible, and the 4 parameters
- * of the change signal reflect these possibilities:
- * as: a list of removed actions
- * a{sb}: a list of actions that had their enabled flag changed
- * a{sv}: a list of actions that had their state changed
- * a{s(bgav)}: a list of new actions added in the same format as
- * the return value of the DescribeAll method

/* Using XML saves us dozens of relocations vs. using the introspection
* structure types. We only need to burn cycles and memory if we
* actually use the exporter -- not in every single app using GIO.
*
* It's also a lot easier to read. :)
+ *
+ * For documentation of this interface, see
+ * https://wiki.gnome.org/Projects/GLib/GApplication/DBusAPI
