+B{python-graph}
+
+A library for working with graphs in Python.
+
+@version: 1.8.2
+
+L{Data structure<pygraph.classes>} classes are located at C{pygraph.classes}.
+
+L{Exception<pygraph.classes.exceptions>} classes are located at C{pygraph.classes.exceptions}.
+
+L{Search filters<pygraph.algorithms.filters>} are located at C{pygraph.algorithms.filters}.
+
+L{Heuristics<pygraph.algorithms.heuristics>} for the A* algorithm are exposed in
+C{pygraph.algorithms.heuristics}.
+
+A quick introductory example:
+
+>>> # Import the module and instantiate a graph object
+>>> from pygraph.classes.graph import graph
+>>> from pygraph.algorithms.searching import depth_first_search
+>>> gr = graph()
+>>> # Add nodes
+>>> gr.add_nodes(['X','Y','Z'])
+>>> gr.add_nodes(['A','B','C'])
+>>> # Add edges
+>>> gr.add_edge(('X','Y'))
+>>> gr.add_edge(('X','Z'))
+>>> gr.add_edge(('A','B'))
+>>> gr.add_edge(('A','C'))
+>>> gr.add_edge(('Y','B'))
+>>> # Depth first search rooted on node X
+>>> st, pre, post = depth_first_search(gr, root='X')
+>>> # Print the spanning tree
+>>> print st
+{'A': 'B', 'C': 'A', 'B': 'Y', 'Y': 'X', 'X': None, 'Z': 'X'}
