+/// \brief Demo of the graph grawing function \ref graphToEps()
+///
+/// This demo program shows examples how to  use the function \ref
+/// graphToEps(). It takes no input but simply creates  six
+/// <tt>.eps</tt> files demonstrating how to draw directed/undirected
+/// graphs, how to handle parallel egdes, how to change the properties
+/// (like color, shape, size, title etc.) of nodes and edges
+/// individually using appropriate \ref maps-page "graphmaps".
