19/// \brief Demo of the graph grawing function \ref graphToEps()
20///
21/// This demo program shows examples how to  use the function \ref
22/// graphToEps(). It takes no input but simply creates  six
23/// <tt>.eps</tt> files demonstrating how to draw directed/undirected
24/// graphs, how to handle parallel egdes, how to change the properties
25/// (like color, shape, size, title etc.) of nodes and edges
26/// individually using appropriate \ref maps-page "graphmaps".
