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.
+
+Syntax:
+\begin{Verbatim}
+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.
+
+
You can access already processed options with the \texttt{config\_get} command
Syntax:
\begin{Verbatim}
-config_get <section> <option> # prints the value of the option
-config_get <variable> <section> <option> # stores the value inside the variable
+# print the value of the option
+config_get <section> <option>
+
+# store the value inside the variable
+config_get <variable> <section> <option>
\end{Verbatim}
In busybox ash the three-option \texttt{config\_get} is faster, because it does not
config_set <section> <option> <value>
\end{Verbatim}
+If a config section is unnamed, an automatically generated name will
+be assigned internally, e.g. \texttt{cfg1}, \texttt{cfg2}, ...
+
+While it is possible, using unnamed sections through these autogenerated names is
+strongly discouraged. Use callbacks or \texttt{config\_foreach} instead.
