    2323/// This demo program shows examples how to  use the function \ref
    2424/// graphToEps(). It takes no input but simply creates  six
    2525/// <tt>.eps</tt> files demonstrating the capability of \ref
    26 /// graphToEps(), and showing how to draw directed/graphs,
     26/// graphToEps(), and showing how to draw directed graphs,
    2727/// how to handle parallel egdes, how to change the properties (like
    2828/// color, shape, size, title etc.) of nodes and arcs individually
