subversion using the following command:
\begin{Verbatim}
-$ svn checkout https://svn.openwrt.org/openwrt/trunk kamikaze
+$ svn checkout svn://svn.openwrt.org/openwrt/trunk kamikaze
\end{Verbatim}
Additionally, there is a trac interface on \href{https://dev.openwrt.org/}{https://dev.openwrt.org/}
Which packages must be built/installed before this package. To reference a dependency defined in the
same Makefile, use \textit{<dependency name>}. If defined as an external package, use
\textit{+<dependency name>}. For a kernel version dependency use: \textit{@LINUX\_2\_<minor version>}
+ \item \texttt{BUILDONLY} (optional) \\
+ Set this option to 1 if you do NOT want your package to appear in menuconfig.
+ This is useful for packages which are only used as build dependencies.
\end{itemize}
\textbf{\texttt{Package/\textit{<name>}/conffiles} (optional):} \\
\item \texttt{make package/\textit{<name>}/configure V=99}
\end{itemize}

+\subsection{Using build environments}
+OpenWrt provides a means of building images for multiple configurations
+which can use multiple targets in one single checkout. These \emph{environments}
+store a copy of the .config file generated by \texttt{make menuconfig} and the contents
+of the \texttt{./files} folder.
+The script \texttt{./scripts/env} is used to manage these environments, it uses
+\texttt{git} (which needs to be installed on your system) as backend for version control.
+
+The command
+\begin{Verbatim}
+ ./scripts/env help
+\end{Verbatim}
+produces a short help text with a list of commands.
+
+To create a new environment named \texttt{current}, run the following command
+\begin{Verbatim}
+ ./scripts/env new current
+\end{Verbatim}
+This will move your \texttt{.config} file and \texttt{./files} (if it exists) to
+the \texttt{env/} subdirectory and create symlinks in the base folder.
+
+After running make menuconfig or changing things in files/, your current state will
+differ from what has been saved before. To show these changes, use:
+\begin{Verbatim}
+ ./scripts/env diff
+\end{Verbatim}
+
+If you want to save these changes, run:
+\begin{Verbatim}
+ ./scripts/env save
+\end{Verbatim}
+If you want to revert your changes to the previously saved copy, run:
+\begin{Verbatim}
+ ./scripts/env revert
+\end{Verbatim}
+
+If you want, you can now create a second environment using the \texttt{new} command.
+It will ask you whether you want to make it a clone of the current environment (e.g.
+for minor changes) or if you want to start with a clean version (e.g. for selecting
+a new target).
+
+To switch to a different environment (e.g. \texttt{test1}), use:
+\begin{Verbatim}
+ ./scripts/env switch test1
+\end{Verbatim}
+
+To rename the current branch to a new name (e.g. \texttt{test2}), use:
+\begin{Verbatim}
+ ./scripts/env rename test2
+\end{Verbatim}
+
+If you want to get rid of environment switching and keep everything in the base directory
+again, use:
+\begin{Verbatim}
+ ./scripts/env clear
+\end{Verbatim}
