+    /** \brief Execute config/console commands
+
+        The Executor interprets parsed config/console commands and executes them. It manages the
+        current execution context (current directory, directory stack and so on).
+
+        The executor is normally called directly by the parser callback for each command.
+
+        Executing the built-in 'exit' command will throw Executor::ExitException. This exception
+        (which is not derived from std::exception since it's not a real exception) must be handled
+        by the caller.
+
+        All directories are managed using weak pointers. If any of the directories expires (current
+        directory, directory stack, last directory) it will be replaced with the root
+        directory. Directories expire when they are destructed or when they are detached from the
+        config tree root node.
