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