+\section{\CMD{psBezier\#}}
+This macro can plot a B\'ezier spline from order 1 up to 9 which needs
+(order+1) pairs of given coordinates.
+
+Given a set of $n+1$ control points $P_0$, $P_1$, \ldots, $P_n$, the corresponding \Index{B\'ezier} curve
+(or \Index{Bernstein-B\'ezier} curve) is given by
+
+\begin{align}
+C(t)=\sum_{i=0}^n P_i B_{i,n}(t)
+\end{align}
+
+Where $B_{i,n}(t)$ is a Bernstein polynomial $B_{i,n}(t)=\binom{n}{i}t^i(1-t)^{n-i}$,
+ and $t \in [0,1]$.
+The Bézier curve starts through the first and last given point and
+lies within the convex hull of all control points. The curve is tangent
+to $P_1-P_0$ and $P_n-P_{n-1}$ at the endpoint.
+Undesirable properties of Bézier curves are their numerical instability for
+large numbers of control points, and the fact that moving a single control
+point changes the global shape of the curve. The former is sometimes avoided
+by smoothly patching together low-order Bézier curves.
+
+The macro \CMD{psBezier} (note the upper case B) expects the number of the order
+and $n=order+1$ pairs of coordinates:
+
+\begin{lstlisting}[style=syntax]
+\psBezier#[<options>](x0,y0)(x1,y1)...(xn,yn)
+\end{lstlisting}
+
+The number of steps between the first and last control points is given
+by the keyword \verb=plotpoints= and preset to 200. It can be
+changed in the usual way.
