+%description
 This package makes it easier to create and render a graph description in 
 the DOT language which from the Python Graphviz graph drawing software.
 
-You can create and assemble a graph object by adding nodes and edges with
-the package. Also the graph can be saved to a file by retrieving its DOT
-source code string, then you can render the graph with the Graphviz graph
-drawing software.}
