+\end{align}
+%
+first discussed in 1818 by Gabriel Lamé (1795--1870)%
+\footnote{Lamé worked on a wide variety of different topics.
+His work on differential geometry and contributions to Fermat's Last Theorem
+are important. He proved the theorem for $n = 7$ in 1839.}.
+A superellipse may be described parametrically by
+%
+\begin{align}
+x = a\cdot\cos^{\frac{2}{r}} t\\
+y = b\cdot\sin^{\frac{2}{r}} t
+\end{align}
+%
+Superellipses with $a=b$ are also known as Lamé curves or Lamé ovals and
+the restriction to $r>2$ is sometimes also made. The following
+table summarizes a few special cases. Piet Hein used $\frac{5}{2}$ with a number of different
+$\frac{a}{b}$ ratios for various of his projects. For example, he used $\frac{a}{b}=\frac{6}{5}$
+for Sergels Torg
+(Sergel's Square) in Stockholm, and $\frac{a}{b}=\frac{3}{2}$ for his table.

+If is a rational, then a superellipse is algebraic. However, for irrational,
+it is transcendental. For even integers, the curve becomes closer to a
+rectangle as increases. The syntax of the \verb+\psLame+ macro is:
+
+\begin{verbatim}
+\psLame[settings]{r}
+\end{verbatim}
+
+It is internally ploted as a parametric plot with $0\le\alpha\le360$. Available keywords
+are \verb+radiusA+ and \verb+radiusB+, both are preset to 1, but can have any valid value
+and unit.
