\subsubsection{The Options}
There are several options to customize the drawing.
-\begin{description}
-\item[\color{red}\texttt{mode = int (default) or ext}:] the mode option allow to
+\begin{optionsenum}
+\item[mode = int (default) or ext:] this option allows to
use either the previously described set of point in the argument, or
a file, containing, line by line (2 columns), the points. Such a
file looks like :
...
xn yn
\end{verbatim}
-\end{description}
+\item[bbox = none (default) or show:] this option allows to draw the
+ added points to form a \emph{bounding box}\footnote{The bounding
+ box is defined by four points place at 15\% around the box
+ defined by $(x_{\min},y_{\min})$, $(x_{\min},y_{\max})$,
+ $(x_{\max},y_{\max})$, and $(x_{\min},y_{\max})$.} and the corresponding
+ triangulation. By default, these triangles are removed at the end of
+ the algorithm.
+\item[color = \meta{value} (default: black):] The color of the
+ drawing.
+\item[colorBbox = \meta{value} (default: black):] The color of the
+ drawing for the elements (points and triangles) belonging to the
+ bounding box.
+\item[print = none (default) or points:] To label the vertices of the
+ triangulations with an adding dot.
+\item[meshpoint = \meta{value} (default: P):] The letter(s) used to
+ label the vertices of the triangulation. It is include in the math
+ mode delimiters \Verb+$...$+. The bounding box points are labeled
+ with a star exponent, and numbered from 1 to 4.
+\item[tikz (boolean, default:false):] By default, this boolean is set
+ to \Verb+false+, and MetaPost (with \Verb+luamplib+) is used to draw
+ the picture. With this option, it is \Verb+tikz+ the \textit{drawing
+ engine}.
+\item[scale = \meta{value} (default: 1cm):] The scale option defines
+ the scale at which the picture is draw (the same for the two
+ axis). It must contain the unit of length (cm,
+ pt, etc.).
+\end{optionsenum}
+
+To illustrate the options, let us show you an example. We consider a
+file \Verb+mesh.txt+:
+\begin{verbatim}
+0.3 0.3
+1.5 1
+4 0
+4.5 2.5
+1.81 2.14
+2.5 0.5
+2.8 1.5
+\end{verbatim}
+\begin{Exemple}
+ \buildMeshBW[%
+ tikz,
+ mode = ext,
+ bbox = show,
+ color = red,
+ colorBbox = blue!30,
+ print = points,
+ meshpoint = x,
+ scale = 1.3cm,
+ ]{mesh.txt}
+\end{Exemple}
+
+\begin{warning}
+The drawing engine is not here very relevant. But it is useful to
+understand how the drawing is made. However, the engine will make sens
+for the so called \emph{inc} macros (section~\ref{sec:inc}), where we
+will be allowed to add code before and after the generated one by
+\luamesh.
