- * Types and functions related to DBusServer.
* A DBusServer represents a server that other applications

- * is represented by a DBusConnection.
+ * is represented by a #DBusConnection.
*
- * @todo Thread safety hasn't been looked at for #DBusServer
+ * @todo Thread safety hasn't been tested much for #DBusServer
* @todo Need notification to apps of disconnection, may matter for some transports
