    1.14 +///
    1.15 +/// This demo program shows examples how to  use the function \ref
    1.16 +/// graphToEps(). It takes no input but simply creates  six
    1.17 +/// <tt>.eps</tt> files demonstrating how to draw directed/undirected
    1.18 +/// graphs, how to handle parallel egdes, how to change the properties
    1.19 +/// (like color, shape, size, title etc.) of nodes and edges
    1.20 +/// individually using appropriate \ref maps-page "graphmaps".
