+\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}
+. /etc/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{/etc/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.
+
+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
+\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}

+\subsubsection{Using the network scripts}
+
+To be able to access the network functions, you need to include
+the necessary shell scripts by running:
+
+\begin{Verbatim}
+. /etc/functions.sh      # common functions
+include /lib/network     # include /lib/network/*.sh
+scan_interfaces          # read and parse the network config
+\end{Verbatim}
+
+Some protocols, such as PPP might change the configured interface names
+at run time (e.g. \texttt{eth0} => \texttt{ppp0} for PPPoE). That's why you have to run
+\texttt{scan\_interfaces} instead of reading the values from the config directly.
+After running \texttt{scan\_interfaces}, the \texttt{'ifname'} option will always contain
+the effective interface name (which is used for IP traffic) and if the
+physical device name differs from it, it will be stored in the \texttt{'device'}
+option.
+That means that running \texttt{config\_get lan ifname}
+after \texttt{scan\_interfaces} might not return the same result as running it before.
+
+After running \texttt{scan\_interfaces}, the following functions are available:
+
+\begin{itemize}
+	\item{\texttt{find\_config \textit{interface}}} \\
+		looks for a network configuration that includes
+  		the specified network interface.
+
+	\item{\texttt{setup\_interface \textit{interface [config] [protocol]}}} \\
+	  will set up the specified interface, optionally overriding the network configuration
+	  name or the protocol that it uses.
+\end{itemize}
+
+\subsubsection{Writing protocol handlers}
+
+You can add custom protocol handlers by adding shell scripts to
+\texttt{/lib/network}. They provide the following two shell functions:
+
+\begin{Verbatim}
+scan_<protocolname>() {
+	local config="$1"
+	# change the interface names if necessary
+}
+
+setup_interface_<protocolname>() {
+	local interface="\$1"
+	local config="\$2"
+	# set up the interface
+}
+\end{Verbatim}
+
+\texttt{scan\_\textit{protocolname}} is optional and only necessary if your protocol
+uses a custom device, e.g. a tunnel or a PPP device.

+The network configuration in Kamikaze is stored in \texttt{/etc/config/network}
+and is divided into interface configurations.
+Each interface configuration either refers directly to an ethernet/wifi
+interface (\texttt{eth0}, \texttt{wl0}, ..) or to a bridge containing multiple interfaces.
+It looks like this:
+
+\begin{Verbatim}
+config interface     "lan"
+    option ifname    "eth0"
+    option proto     "static"
+    option ipaddr    "192.168.1.1"
+    option netmask   "255.255.255.0"
+    option gateway   "192.168.1.254"
+    option dns       "192.168.1.254"
+\end{Verbatim}
+
+\texttt{ifname} specifies the Linux interface name.
+If you want to use bridging on one or more interfaces, set \texttt{ifname} to a list
+of interfaces and add:
+\begin{Verbatim}
+    option type     "bridge"
+\end{Verbatim}
+
+It is possible to use VLAN tagging on an interface simply by adding the VLAN IDs
+to it, e.g. \texttt{eth0.1}. These can be nested as well.
+
+This sets up a simple static configuration for \texttt{eth0}. \texttt{proto} specifies the
+protocol used for the interface. The default image usually provides \texttt{'none'}
+\texttt{'static'}, \texttt{'dhcp'} and \texttt{'pppoe'}. Others can be added by installing additional
+packages.
+
+When using the \texttt{'static'} method like in the example, the  options \texttt{ipaddr} and 
+\texttt{netmask} are mandatory, while \texttt{gateway} and \texttt{dns} are optional.
+DHCP currently only accepts \texttt{ipaddr} (IP address to request from the server)
+and \texttt{hostname} (client hostname identify as) - both are optional.
+
+PPP based protocols (\texttt{pppoe}, \texttt{pptp}, ...) accept these options:
+\begin{itemize}
+    \item{username} \\
+        The PPP username (usually with PAP authentication)
+    \item{password} \\
+        The PPP password
+    \item{keepalive} \\
+        Ping the PPP server (using LCP). The value of this option
+        specifies the maximum number of failed pings before reconnecting.
+        The ping interval defaults to 5, but can be changed by appending 
+        ",<interval>" to the keepalive value
+    \item{demand} \\
+        Use Dial on Demand (value specifies the maximum idle time.
+        
+    \item{server: (pptp)} \\
+        The remote pptp server IP
+\end{itemize}
+        
+For all protocol types, you can also specify the MTU by using the \texttt{mtu} option.
+
+
+\subsubsection{Setting up the switch (currently broadcom only)}
+
+The switch configuration is set by adding a \texttt{'switch'} config section.
+Example: 
+
+\begin{Verbatim}
+config switch eth0
+    option vlan0 "1 2 3 4 5*"
+    option vlan1 "0 5"
+\end{Verbatim}
+
+On Broadcom hardware the section name needs to be eth0, as the switch driver
+does not detect the switch on any other physical device.
+Every vlan option needs to have the name vlan<n> where <n> is the VLAN number
+as used in the switch driver.
+As value it takes a list of ports with these optional suffixes:
+
+\begin{itemize}
+    \item{\texttt{'*'}:}
+        Set the default VLAN (PVID) of the Port to the current VLAN
+    \item{\texttt{'u'}:}
+        Force the port to be untagged
+    \item{\texttt{'t'}:}
+        Force the port to be tagged
+\end{itemize}
+
+The CPU port defaults to tagged, all other ports to untagged.
+On Broadcom hardware the CPU port is always 5. The other ports may vary with 
+different hardware.
