    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/undirected graphs,

    27 /// how to handle parallel egdes, how to change the properties (like

    28 /// color, shape, size, title etc.) of nodes and edges individually

    29 /// using appropriate \ref maps-page "graph maps".
