/**
 * GDebugController:
 *
 * `GDebugController` is an interface to expose control of debugging features and
 * debug output.
 *
 * It is implemented on Linux using [class@Gio.DebugControllerDBus], which
 * exposes a D-Bus interface to allow authenticated peers to control debug
 * features in this process.
 *
 * Whether debug output is enabled is exposed as
 * [property@Gio.DebugController:debug-enabled]. This controls
 * [func@GLib.log_set_debug_enabled] by default. Application code may
 * connect to the [signal@GObject.Object::notify] signal for it
 * to control other parts of its debug infrastructure as necessary.
 *
 * If your application or service is using the default GLib log writer function,
 * creating one of the built-in implementations of `GDebugController` should be
 * all that’s needed to dynamically enable or disable debug output.
 *
 * Since: 2.72
