+/**
+ * @brief A loader and multiplexer to use multiple backends.
+ *
+ * Charon allows the use of multiple configuration backends simultaneously. To
+ * access all this backends by a single call, this class wraps multiple
+ * backends behind a single object. It is also responsible for loading
+ * the backend modules and cleaning them up.
+ * A backend may be writeable or not. All backends implement the backend_t
+ * interface, those who are writeable additionally implement the
+ * writeable_backend_t interface. Adding configs to the backend_manager will
+ * be redirected to the first writeable backend.
