-\subsubsection{Structure of the configuration files}
-
-The config files are divided into sections and options/values.
-
-Every section has a type, but does not necessarily have a name.
-Every option has a name and a value and is assigned to the section
-it was written under.
-
-Syntax:
-
-\begin{Verbatim}
-config      <type> ["<name>"]      # Section
-    option  <name> "<value>"       # Option
-\end{Verbatim}
-
-Every parameter needs to be a single string and is formatted exactly
-like a parameter for a shell function. The same rules for Quoting and
-special characters also apply, as it is parsed by the shell.
-
-\subsubsection{Parsing configuration files in custom scripts}
-
-To be able to load configuration files, you need to include the common
-functions with:
-
-\begin{Verbatim}
-. /lib/functions.sh
-\end{Verbatim}
-
-Then you can use \texttt{config\_load \textit{<name>}} to load config files. The function
-first checks for \textit{<name>} as absolute filename and falls back to loading
-it from \texttt{/etc/config} (which is the most common way of using it).
-
-If you want to use special callbacks for sections and/or options, you
-need to define the following shell functions before running \texttt{config\_load}
-(after including \texttt{/lib/functions.sh}):
-
-\begin{Verbatim}
-config_cb() {
-    local type="$1"
-    local name="$2"
-    # commands to be run for every section
-}
-
-option_cb() {
-    # commands to be run for every option
-}
-\end{Verbatim}
-
-You can also alter \texttt{option\_cb} from \texttt{config\_cb} based on the section type.
-This allows you to process every single config section based on its type
-individually.
-
-\texttt{config\_cb} is run every time a new section starts (before options are being
-processed). You can access the last section through the \texttt{CONFIG\_SECTION}
-variable. Also an extra call to \texttt{config\_cb} (without a new section) is generated
-after \texttt{config\_load} is done.
-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}
-# 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
-result in an extra fork, so it is the preferred way.
-
-Additionally you can also modify or add options to sections by using the
-\texttt{config\_set} command.
-
-Syntax:
-
-\begin{Verbatim}
-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.
