+\subsection{Coordinates}
+By default the coordinates \verb|(10,10)| are used if the environment \Lenv{pspicture}
+is called without any given coordinates. This behaviour can be changed if you are running
+the document with \Lprog{lualatex}. Then you can use the optional argument \Lkeyword{calcframe}
+to allow the internal calculation of the box width and height. it needs two \Lprog{lualatex}
+runs to get the coordinates. The values are written into a file \verb|\jobname-<No>.psaux| and read
+in the next run.
+
+With the optional argument \Lkeyword{margin} it is possible to add white space to the calculated coordinates.
+The keyword must be set with the command \Lcs{psset} \emph{before} the environment \Lenv{pspicture}, otherwise it is too late.
+
+\begin{itemize}
+\item \verb|margin=5mm| will add 5mm on all sides of the box.
+\item \verb|margin={5mm,1cm}| will add 5mm on the left side and 1cm on the lower side of the box.
+\item \verb|margin={2mm,3,4,5pt}| will add 2mm on the left, 3\Lcs{psunit} at the bottom, 4\Lcs{psunit} on
+the right and 5pt on the top of the box. With the optional argument \Lkeyword{showframe} the calculated
+box coordinates can be visible. Additional white space is marked by a box with dashed lines.
+\end{itemize}
+
+Without a given unit all values are used with the current defined PSTricks unit. But remember
+that this will only work with \Lprog{lualatex}.
+
+The following example shows the same curve, but with different coordinates.

+\section{\LuaLaTeX}\label{lua}
+Currently one has to use package \LPack{auto-pst-pdf-lua} if a document with
+\PSTricks-code should be run \emph{directly} with  \LuaLaTeX, without using
+GhostScript. This version has experimental basic support for the lua package
+\LPack{luapstricks.lua}, available from \url{https://github.com/zauguin/luapstricks}.
