That allows you to process sections both before and after all options were
processed.
+Another way of iterating on config sections is using the \texttt{config\_foreach} command.

+config_foreach <function name> [<sectiontype>] [<arguments...>]
+\end{Verbatim}

+This command will run the supplied function for every single config section in the currently
+loaded config. The section name will be passed to the function as argument 1.
+If the section type is added to the command line, the function will only be called for
+sections of the given type.
