+ * @brief A multiplexer to use multiple cfg_store backends.
+ *
+ * Charon allows the use of multiple cfg_store backends simultaneously. To
+ * access all this backends by a single call, this class wraps multiple
+ * backends behind a single object.
+ * Backends may be registered and unregister at runtime dynamically.
