+Release history
+===============
+
+0.11
+----
+
+- Stabilize the order of elements in dot file exports,
+  patch from bitbucket user 'pombredanne'.
+
+- Tweak setup.py file to remove dependency on distribute (but
+  keep the dependency on setuptools)
+
+
+0.10.2
+------
+
+- There where no classifiers in the package metadata due to a bug
+  in setup.py
+
+0.10.1
+------
+
+This is a bugfix release
+
+Bug fixes:
+
+- Issue #3: The source archive contains a README.txt
+  while the setup file refers to ReadMe.txt.
+
+  This is caused by a misfeature in distutils, as a
+  workaround I've renamed ReadMe.txt to README.txt
+  in the source tree and setup file.
+
+
+0.10
+-----
+
+This is a minor feature release
+
+Features:
+
+- Do not use "2to3" to support Python 3.
+
+  As a side effect of this altgraph now supports
+  Python 2.6 and later, and no longer supports
+  earlier releases of Python.
+
+- The order of attributes in the Dot output
+  is now always alphabetical.
+
+  With this change the output will be consistent
+  between runs and Python versions.
+
+0.9
+---
+
+This is a minor bugfix release
+
+Features:
+
+- Added ``altgraph.ObjectGraph.ObjectGraph.nodes``, a method
+  yielding all nodes in an object graph.
+
+Bugfixes:
+
+- The 0.8 release didn't work with py2app when using
+  python 3.x.
+
+
+0.8
+-----
+
+This is a minor feature release. The major new feature
+is a extensive set of unittests, which explains almost
+all other changes in this release.
+
+Bugfixes:
+
+- Installing failed with Python 2.5 due to using a distutils
+  class that isn't available in that version of Python
+  (issue #1 on the issue tracker)
+
+- ``altgraph.GraphStat.degree_dist`` now actually works
+
+- ``altgraph.Graph.add_edge(a, b, create_nodes=False)`` will
+  no longer create the edge when one of the nodes doesn't
+  exist.
+
+- ``altgraph.Graph.forw_topo_sort`` failed for some sparse graphs.
+
+- ``altgraph.Graph.back_topo_sort`` was completely broken in
+  previous releases.
+
+- ``altgraph.Graph.forw_bfs_subgraph`` now actually works.
+
+- ``altgraph.Graph.back_bfs_subgraph`` now actually works.
+
+- ``altgraph.Graph.iterdfs`` now returns the correct result
+  when the ``forward`` argument is ``False``.
+
+- ``altgraph.Graph.iterdata`` now returns the correct result
+  when the ``forward`` argument is ``False``.
+
+
+Features:
+
+- The ``altgraph.Graph`` constructor now accepts an argument
+  that contains 2- and 3-tuples instead of requireing that
+  all items have the same size. The (optional) argument can now
+  also be any iterator.
+
+- ``altgraph.Graph.Graph.add_node`` has no effect when you
+  add a hidden node.
+
+- The private method ``altgraph.Graph._bfs`` is no longer
+  present.
+
+- The private method ``altgraph.Graph._dfs`` is no longer
+  present.
+
+- ``altgraph.ObjectGraph`` now has a ``__contains__`` methods,
+  which means you can use the ``in`` operator to check if a
+  node is part of a graph.
+
+- ``altgraph.GraphUtil.generate_random_graph`` will raise
+  ``GraphError`` instead of looping forever when it is
+  impossible to create the requested graph.
+
+- ``altgraph.Dot.edge_style`` raises ``GraphError`` when
+  one of the nodes is not present in the graph. The method
+  silently added the tail in the past, but without ensuring
+  a consistent graph state.
+
+- ``altgraph.Dot.save_img`` now works when the mode is
+  ``"neato"``.
+
+0.7.2
+-----
+
+This is a minor bugfix release
+
+Bugfixes:
+
+- distutils didn't include the documentation subtree
+
+0.7.1
+-----
+
+This is a minor feature release
+
+Features:
+
+- Documentation is now generated using `sphinx <http://pypi.python.org/pypi/sphinx>`_
+  and can be viewed at <http://packages.python.org/altgraph>.
+
+- The repository has moved to bitbucket
+
+- ``altgraph.GraphStat.avg_hops`` is no longer present, the function had no
+  implementation and no specified behaviour.
+
+- the module ``altgraph.compat`` is gone, which means altgraph will no
+  longer work with Python 2.3.
+
+
+0.7.0
+-----
+
+This is a minor feature release.
+
+Features:
+
+- Support for Python 3
+
+- It is now possible to run tests using 'python setup.py test'
+
+  (The actual testsuite is still very minimal though)

+:mod:`altgraph` --- A Python Graph Library
+==================================================
+
+.. module:: altgraph
+   :synopsis: A directional graph for python
+
+altgraph is a fork of `graphlib <http://pygraphlib.sourceforge.net>`_ tailored
+to use newer Python 2.3+ features, including additional support used by the
+py2app suite (modulegraph and macholib, specifically).
+
+altgraph is a python based graph (network) representation and manipulation package.
+It has started out as an extension to the `graph_lib module <http://www.ece.arizona.edu/~denny/python_nest/graph_lib_1.0.1.html>`_
+written by Nathan Denny it has been significantly optimized and expanded.
+
+The :class:`altgraph.Graph.Graph` class is loosely modeled after the `LEDA <http://www.algorithmic-solutions.com/enleda.htm>`_ 
+(Library of Efficient Datatypes)  representation. The library
+includes methods for constructing graphs, BFS and DFS traversals,
+topological sort, finding connected components, shortest paths as well as a number
+graph statistics functions. The library can also visualize graphs
+via `graphviz <http://www.research.att.com/sw/tools/graphviz/>`_.
+
+
+.. exception:: GraphError
+
+   Exception raised when methods are called with bad values of
+   an inconsistent state.

+:mod:`altgraph.Dot` --- Interface to the dot language
+=====================================================
+
+.. module:: altgraph.Dot
+   :synopsis: Interface to the dot language as used by Graphviz..
+
+The :py:mod:`~altgraph.Dot` module provides a simple interface to the
+file format used in the `graphviz`_ program. The module is intended to 
+offload the most tedious part of the process (the **dot** file generation) 
+while transparently exposing most of its features.
+
+.. _`graphviz`: <http://www.research.att.com/sw/tools/graphviz/>`_
+
+To display the graphs or to generate image files the `graphviz`_
+package needs to be installed on the system, moreover the :command:`dot` and :command:`dotty` programs must
+be accesible in the program path so that they can be ran from processes spawned
+within the module. 
+
+Example usage
+-------------
+
+Here is a typical usage::
+
+    from altgraph import Graph, Dot
+
+    # create a graph
+    edges = [ (1,2), (1,3), (3,4), (3,5), (4,5), (5,4) ]
+    graph = Graph.Graph(edges)
+    
+    # create a dot representation of the graph
+    dot = Dot.Dot(graph)
+
+    # display the graph
+    dot.display()
+
+    # save the dot representation into the mydot.dot file
+    dot.save_dot(file_name='mydot.dot')
+
+    # save dot file as gif image into the graph.gif file
+    dot.save_img(file_name='graph', file_type='gif')
+
+
+Directed graph and non-directed graph
+-------------------------------------
+
+Dot class can use for both directed graph and non-directed graph
+by passing *graphtype* parameter.
+
+Example::
+
+    # create directed graph(default)
+    dot = Dot.Dot(graph, graphtype="digraph")
+
+    # create non-directed graph
+    dot = Dot.Dot(graph, graphtype="graph")
+
+
+Customizing the output
+----------------------
+
+The graph drawing process may be customized by passing
+valid :command:`dot` parameters for the nodes and edges. For a list of all
+parameters see the `graphviz`_ documentation.
+
+Example::
+
+    # customizing the way the overall graph is drawn
+    dot.style(size='10,10', rankdir='RL', page='5, 5' , ranksep=0.75)
+
+    # customizing node drawing
+    dot.node_style(1, label='BASE_NODE',shape='box', color='blue' )
+    dot.node_style(2, style='filled', fillcolor='red')
+
+    # customizing edge drawing
+    dot.edge_style(1, 2, style='dotted')
+    dot.edge_style(3, 5, arrowhead='dot', label='binds', labelangle='90')
+    dot.edge_style(4, 5, arrowsize=2, style='bold')
+
+
+    .. note:: 
+       
+       dotty (invoked via :py:func:`~altgraph.Dot.display`) may not be able to
+       display all graphics styles. To verify the output save it to an image 
+       file and look at it that way.
+
+Valid attributes
+----------------
+
+- dot styles, passed via the :py:meth:`Dot.style` method::
+
+    rankdir = 'LR'   (draws the graph horizontally, left to right)
+    ranksep = number (rank separation in inches)
+
+- node attributes, passed via the :py:meth:`Dot.node_style` method::
+
+     style = 'filled' | 'invisible' | 'diagonals' | 'rounded'
+     shape = 'box' | 'ellipse' | 'circle' | 'point' | 'triangle'
+
+- edge attributes, passed via the :py:meth:`Dot.edge_style` method::
+
+     style     = 'dashed' | 'dotted' | 'solid' | 'invis' | 'bold'
+     arrowhead = 'box' | 'crow' | 'diamond' | 'dot' | 'inv' | 'none' | 'tee' | 'vee'
+     weight    = number (the larger the number the closer the nodes will be)
+
+- valid `graphviz colors <http://www.research.att.com/~erg/graphviz/info/colors.html>`_
+
+- for more details on how to control the graph drawing process see the 
+  `graphviz reference <http://www.research.att.com/sw/tools/graphviz/refs.html>`_.
+
+
+Class interface
+---------------
+
+.. class:: Dot(graph[, nodes[, edgefn[, nodevisitor[, edgevisitor[, name[, dot[, dotty[, neato[, graphtype]]]]]]]]])
+
+  Creates a new Dot generator based on the specified 
+  :class:`Graph <altgraph.Graph.Graph>`.  The Dot generator won't reference
+  the *graph* once it is constructed.
+
+  If the *nodes* argument is present it is the list of nodes to include
+  in the graph, otherwise all nodes in *graph* are included.
+  
+  If the *edgefn* argument is present it is a function that yields the
+  nodes connected to another node, this defaults to 
+  :meth:`graph.out_nbr <altgraph.Graph.Graph.out_nbr>`. The constructor won't
+  add edges to the dot file unless both the head and tail of the edge
+  are in *nodes*.
+
+  If the *name* is present it specifies the name of the graph in the resulting
+  dot file. The default is ``"G"``.
+
+  The functions *nodevisitor* and *edgevisitor* return the default style
+  for a given edge or node (both default to functions that return an empty
+  style).
+
+  The arguments *dot*, *dotty* and *neato* are used to pass the path to 
+  the corresponding `graphviz`_ command.
+
+
+Updating graph attributes
+.........................
+
+.. method:: Dot.style(\**attr)
+
+   Sets the overall style (graph attributes) to the given attributes.
+
+   See `Valid Attributes`_ for more information about the attributes.
+
+.. method:: Dot.node_style(node, \**attr)
+
+   Sets the style for *node* to the given attributes.
+
+   This method will add *node* to the graph when it isn't already 
+   present.
+
+   See `Valid Attributes`_ for more information about the attributes.
+
+.. method:: Dot.all_node_style(\**attr)
+
+   Replaces the current style for all nodes
+
+
+.. method:: edge_style(head, tail, \**attr)
+
+   Sets the style of an edge to the given attributes. The edge will
+   be added to the graph when it isn't already present, but *head*
+   and *tail* must both be valid nodes.
+
+   See `Valid Attributes`_ for more information about the attributes.
+
+
+
+Emitting output
+...............
+
+.. method:: Dot.display([mode])
+
+   Displays the current graph via dotty.
+
+   If the *mode* is ``"neato"`` the dot file is processed with
+   the neato command before displaying.
+
+   This method won't return until the dotty command exits.
+
+.. method:: save_dot(filename)
+
+   Saves the current graph representation into the given file.
+
+   .. note::
+
+       For backward compatibility reasons this method can also
+       be called without an argument, it will then write the graph
+       into a fixed filename (present in the attribute :data:`Graph.temp_dot`).
+
+       This feature is deprecated and should not be used.
+
+
+.. method:: save_image(file_name[, file_type[, mode]])
+
+   Saves the current graph representation as an image file. The output
+   is written into a file whose basename is *file_name* and whose suffix
+   is *file_type*.
+
+   The *file_type* specifies the type of file to write, the default
+   is ``"gif"``.
+
+   If the *mode* is ``"neato"`` the dot file is processed with
+   the neato command before displaying.
+
+   .. note::
+
+       For backward compatibility reasons this method can also
+       be called without an argument, it will then write the graph
+       with a fixed basename (``"out"``).
+
+       This feature is deprecated and should not be used.
+
+.. method:: iterdot()
+
+   Yields all lines of a `graphviz`_ input file (including line endings).
+
+.. method:: __iter__()
+
+   Alias for the :meth:`iterdot` method.

+:mod:`altgraph.Graph` --- Basic directional graphs
+==================================================
+
+.. module:: altgraph.Graph
+   :synopsis: Basic directional graphs.
+
+The module :mod:`altgraph.Graph` provides a class :class:`Graph` that
+represents a directed graph with *N* nodes and *E* edges.
+
+.. class:: Graph([edges])
+
+  Constructs a new empty :class:`Graph` object. If the optional
+  *edges* parameter is supplied, updates the graph by adding the
+  specified edges. 
+  
+  All of the elements in *edges* should be tuples with two or three 
+  elements. The first two elements of the tuple are the source and
+  destination node of the edge, the optional third element is the
+  edge data.  The source and destination nodes are added to the graph
+  when the aren't already present.
+
+
+Node related methods
+--------------------
+
+.. method:: Graph.add_node(node[, node_data])
+
+   Adds a new node to the graph if it is not already present. The new

+
+   If *condition* is specified and the condition callable returns
+   False for the associated data this method will not yield the
+   associated data and will not follow the edges for the node.
+
+   If forward is True (the default) edges are traversed in forward
+   direction, otherwise they are traversed in reverse direction.
+
+.. method:: Graph.forw_bfs(start[, end])

+   the forward parameter.  
+   
+   If the distance between all neighbouring nodes is 1 the hop number 
+   corresponds to the shortest distance between the nodes.  
+
+   Typical usage::
+
+        >>> print graph.get_hops(1, 8)
+        >>> [(1, 0), (2, 1), (3, 1), (4, 2), (5, 3), (7, 4), (8, 5)]
+        # node 1 is at 0 hops
+        # node 2 is at 1 hop
+        # ...
+        # node 8 is at 5 hops
+
+
+Graph statistics
+----------------
+
+.. method:: Graph.connected()
+
+   Returns True iff every node in the graph can be reached from
+   every other node.
+
+.. method:: Graph.clust_coef(node)
+
+   Returns the local clustering coefficient of node. 
+
+   The local cluster coefficient is the proportion of the actual number
+   of edges between neighbours of node and the maximum number of
+   edges between those nodes.

+==================================================
+
+.. module:: altgraph.GraphAlgo
+   :synopsis: Basic graphs algoritms
+
+.. function:: dijkstra(graph, start[, end])
+
+   Dijkstra's algorithm for shortest paths.
+
+   Find shortest paths from the  start node to all nodes nearer 
+   than or equal to the *end* node. The edge data is assumed to be the edge length.
+
+   .. note::
+
+       Dijkstra's algorithm is only guaranteed to work correctly when all edge lengths are positive.
+       This code does not verify this property for all edges (only the edges examined until the end
+       vertex is reached), but will correctly compute shortest paths even for some graphs with negative
+       edges, and will raise an exception if it discovers that a negative edge has caused it to make a mistake.
+
+
+.. function:: shortest_path(graph, start, end)
+
+   Find a single shortest path from the given start node to the given end node.
+   The input has the same conventions as :func:`dijkstra`. The output is a list

+
+.. function:: degree_dist(graph[, limits[, bin_num[, mode]]])
+
+   Groups the number of edges per node into *bin_num* bins
+   and returns the list of those bins. Every item in the result
+   is a tuple with the center of the bin and the number of items
+   in that bin.
+
+   When the *limits* argument is present it must be a tuple with
+   the mininum and maximum number of edges that get binned (that
+   is, when *limits* is ``(4, 10)`` only nodes with between 4
+   and 10 edges get counted.
+
+   The *mode* argument is used to count incoming (``'inc'``) or
+   outgoing (``'out'``) edges. The default is to count the outgoing
+   edges.

+offload the most tedious part of the process (the <strong>dot</strong> file generation)

+<p>To display the graphs or to generate image files the <a class="reference external" href="&lt;http://www.research.att.com/sw/tools/graphviz/&gt;`_">graphviz</a>
+package needs to be installed on the system, moreover the <strong class="command">dot</strong> and <strong class="command">dotty</strong> programs must
+be accesible in the program path so that they can be ran from processes spawned
+within the module.</p>

+Release history
+===============
+
+0.12
+----
+
+- Added ``ObjectGraph.edgeData`` to retrieve the edge data
+  from a specific edge.
+
+- Added ``AltGraph.update_edge_data`` and ``ObjectGraph.updateEdgeData``
+  to update the data associated with a graph edge.
+
+0.11
+----
+
+- Stabilize the order of elements in dot file exports,
+  patch from bitbucket user 'pombredanne'.
+
+- Tweak setup.py file to remove dependency on distribute (but
+  keep the dependency on setuptools)
+
+
+0.10.2
+------
+
+- There where no classifiers in the package metadata due to a bug
+  in setup.py
+
+0.10.1
+------
+
+This is a bugfix release
+
+Bug fixes:
+
+- Issue #3: The source archive contains a README.txt
+  while the setup file refers to ReadMe.txt.
+
+  This is caused by a misfeature in distutils, as a
+  workaround I've renamed ReadMe.txt to README.txt
+  in the source tree and setup file.
+
+
+0.10
+-----
+
+This is a minor feature release
+
+Features:
+
+- Do not use "2to3" to support Python 3.
+
+  As a side effect of this altgraph now supports
+  Python 2.6 and later, and no longer supports
+  earlier releases of Python.
+
+- The order of attributes in the Dot output
+  is now always alphabetical.
+
+  With this change the output will be consistent
+  between runs and Python versions.
+
+0.9
+---
+
+This is a minor bugfix release
+
+Features:
+
+- Added ``altgraph.ObjectGraph.ObjectGraph.nodes``, a method
+  yielding all nodes in an object graph.
+
+Bugfixes:
+
+- The 0.8 release didn't work with py2app when using
+  python 3.x.
+
+
+0.8
+-----
+
+This is a minor feature release. The major new feature
+is a extensive set of unittests, which explains almost
+all other changes in this release.
+
+Bugfixes:
+
+- Installing failed with Python 2.5 due to using a distutils
+  class that isn't available in that version of Python
+  (issue #1 on the issue tracker)
+
+- ``altgraph.GraphStat.degree_dist`` now actually works
+
+- ``altgraph.Graph.add_edge(a, b, create_nodes=False)`` will
+  no longer create the edge when one of the nodes doesn't
+  exist.
+
+- ``altgraph.Graph.forw_topo_sort`` failed for some sparse graphs.
+
+- ``altgraph.Graph.back_topo_sort`` was completely broken in
+  previous releases.
+
+- ``altgraph.Graph.forw_bfs_subgraph`` now actually works.
+
+- ``altgraph.Graph.back_bfs_subgraph`` now actually works.
+
+- ``altgraph.Graph.iterdfs`` now returns the correct result
+  when the ``forward`` argument is ``False``.
+
+- ``altgraph.Graph.iterdata`` now returns the correct result
+  when the ``forward`` argument is ``False``.
+
+
+Features:
+
+- The ``altgraph.Graph`` constructor now accepts an argument
+  that contains 2- and 3-tuples instead of requireing that
+  all items have the same size. The (optional) argument can now
+  also be any iterator.
+
+- ``altgraph.Graph.Graph.add_node`` has no effect when you
+  add a hidden node.
+
+- The private method ``altgraph.Graph._bfs`` is no longer
+  present.
+
+- The private method ``altgraph.Graph._dfs`` is no longer
+  present.
+
+- ``altgraph.ObjectGraph`` now has a ``__contains__`` methods,
+  which means you can use the ``in`` operator to check if a
+  node is part of a graph.
+
+- ``altgraph.GraphUtil.generate_random_graph`` will raise
+  ``GraphError`` instead of looping forever when it is
+  impossible to create the requested graph.
+
+- ``altgraph.Dot.edge_style`` raises ``GraphError`` when
+  one of the nodes is not present in the graph. The method
+  silently added the tail in the past, but without ensuring
+  a consistent graph state.
+
+- ``altgraph.Dot.save_img`` now works when the mode is
+  ``"neato"``.
+
+0.7.2
+-----
+
+This is a minor bugfix release
+
+Bugfixes:
+
+- distutils didn't include the documentation subtree
+
+0.7.1
+-----
+
+This is a minor feature release
+
+Features:
+
+- Documentation is now generated using `sphinx <http://pypi.python.org/pypi/sphinx>`_
+  and can be viewed at <http://packages.python.org/altgraph>.
+
+- The repository has moved to bitbucket
+
+- ``altgraph.GraphStat.avg_hops`` is no longer present, the function had no
+  implementation and no specified behaviour.
+
+- the module ``altgraph.compat`` is gone, which means altgraph will no
+  longer work with Python 2.3.
+
+
+0.7.0
+-----
+
+This is a minor feature release.
+
+Features:
+
+- Support for Python 3
+
+- It is now possible to run tests using 'python setup.py test'
+
+  (The actual testsuite is still very minimal though)

+:mod:`altgraph` --- A Python Graph Library
+==================================================
+
+.. module:: altgraph
+   :synopsis: A directional graph for python
+
+altgraph is a fork of `graphlib <http://pygraphlib.sourceforge.net>`_ tailored
+to use newer Python 2.3+ features, including additional support used by the
+py2app suite (modulegraph and macholib, specifically).
+
+altgraph is a python based graph (network) representation and manipulation package.
+It has started out as an extension to the `graph_lib module <http://www.ece.arizona.edu/~denny/python_nest/graph_lib_1.0.1.html>`_
+written by Nathan Denny it has been significantly optimized and expanded.
+
+The :class:`altgraph.Graph.Graph` class is loosely modeled after the `LEDA <http://www.algorithmic-solutions.com/enleda.htm>`_ 
+(Library of Efficient Datatypes)  representation. The library
+includes methods for constructing graphs, BFS and DFS traversals,
+topological sort, finding connected components, shortest paths as well as a number
+graph statistics functions. The library can also visualize graphs
+via `graphviz <http://www.research.att.com/sw/tools/graphviz/>`_.

+:mod:`altgraph.Dot` --- Interface to the dot language
+=====================================================
+
+.. module:: altgraph.Dot
+   :synopsis: Interface to the dot language as used by Graphviz..
+
+The :py:mod:`~altgraph.Dot` module provides a simple interface to the
+file format used in the `graphviz`_ program. The module is intended to 
+offload the most tedious part of the process (the **dot** file generation) 
+while transparently exposing most of its features.
+
+.. _`graphviz`: <http://www.research.att.com/sw/tools/graphviz/>`_
+
+To display the graphs or to generate image files the `graphviz`_
+package needs to be installed on the system, moreover the :command:`dot` and :command:`dotty` programs must
+be accesible in the program path so that they can be ran from processes spawned
+within the module. 
+
+Example usage
+-------------
+
+Here is a typical usage::
+
+    from altgraph import Graph, Dot
+
+    # create a graph
+    edges = [ (1,2), (1,3), (3,4), (3,5), (4,5), (5,4) ]
+    graph = Graph.Graph(edges)
+    
+    # create a dot representation of the graph
+    dot = Dot.Dot(graph)
+
+    # display the graph
+    dot.display()
+
+    # save the dot representation into the mydot.dot file
+    dot.save_dot(file_name='mydot.dot')
+
+    # save dot file as gif image into the graph.gif file
+    dot.save_img(file_name='graph', file_type='gif')
+
+
+Directed graph and non-directed graph
+-------------------------------------
+
+Dot class can use for both directed graph and non-directed graph
+by passing *graphtype* parameter.
+
+Example::
+
+    # create directed graph(default)
+    dot = Dot.Dot(graph, graphtype="digraph")
+
+    # create non-directed graph
+    dot = Dot.Dot(graph, graphtype="graph")
+
+
+Customizing the output
+----------------------
+
+The graph drawing process may be customized by passing
+valid :command:`dot` parameters for the nodes and edges. For a list of all
+parameters see the `graphviz`_ documentation.
+
+Example::
+
+    # customizing the way the overall graph is drawn
+    dot.style(size='10,10', rankdir='RL', page='5, 5' , ranksep=0.75)
+
+    # customizing node drawing
+    dot.node_style(1, label='BASE_NODE',shape='box', color='blue' )
+    dot.node_style(2, style='filled', fillcolor='red')
+
+    # customizing edge drawing
+    dot.edge_style(1, 2, style='dotted')
+    dot.edge_style(3, 5, arrowhead='dot', label='binds', labelangle='90')
+    dot.edge_style(4, 5, arrowsize=2, style='bold')
+
+
+    .. note:: 
+       
+       dotty (invoked via :py:func:`~altgraph.Dot.display`) may not be able to
+       display all graphics styles. To verify the output save it to an image 
+       file and look at it that way.
+
+Valid attributes
+----------------
+
+- dot styles, passed via the :py:meth:`Dot.style` method::
+
+    rankdir = 'LR'   (draws the graph horizontally, left to right)
+    ranksep = number (rank separation in inches)
+
+- node attributes, passed via the :py:meth:`Dot.node_style` method::
+
+     style = 'filled' | 'invisible' | 'diagonals' | 'rounded'
+     shape = 'box' | 'ellipse' | 'circle' | 'point' | 'triangle'
+
+- edge attributes, passed via the :py:meth:`Dot.edge_style` method::
+
+     style     = 'dashed' | 'dotted' | 'solid' | 'invis' | 'bold'
+     arrowhead = 'box' | 'crow' | 'diamond' | 'dot' | 'inv' | 'none' | 'tee' | 'vee'
+     weight    = number (the larger the number the closer the nodes will be)
+
+- valid `graphviz colors <http://www.research.att.com/~erg/graphviz/info/colors.html>`_
+
+- for more details on how to control the graph drawing process see the 
+  `graphviz reference <http://www.research.att.com/sw/tools/graphviz/refs.html>`_.
+
+
+Class interface
+---------------
+
+.. class:: Dot(graph[, nodes[, edgefn[, nodevisitor[, edgevisitor[, name[, dot[, dotty[, neato[, graphtype]]]]]]]]])
+
+  Creates a new Dot generator based on the specified 
+  :class:`Graph <altgraph.Graph.Graph>`.  The Dot generator won't reference
+  the *graph* once it is constructed.
+
+  If the *nodes* argument is present it is the list of nodes to include
+  in the graph, otherwise all nodes in *graph* are included.
+  
+  If the *edgefn* argument is present it is a function that yields the
+  nodes connected to another node, this defaults to 
+  :meth:`graph.out_nbr <altgraph.Graph.Graph.out_nbr>`. The constructor won't
+  add edges to the dot file unless both the head and tail of the edge
+  are in *nodes*.
+
+  If the *name* is present it specifies the name of the graph in the resulting
+  dot file. The default is ``"G"``.
+
+  The functions *nodevisitor* and *edgevisitor* return the default style
+  for a given edge or node (both default to functions that return an empty
+  style).
+
+  The arguments *dot*, *dotty* and *neato* are used to pass the path to 
+  the corresponding `graphviz`_ command.
+
+
+Updating graph attributes
+.........................
+
+.. method:: Dot.style(\**attr)
+
+   Sets the overall style (graph attributes) to the given attributes.
+
+   See `Valid Attributes`_ for more information about the attributes.
+
+.. method:: Dot.node_style(node, \**attr)
+
+   Sets the style for *node* to the given attributes.
+
+   This method will add *node* to the graph when it isn't already 
+   present.
+
+   See `Valid Attributes`_ for more information about the attributes.
+
+.. method:: Dot.all_node_style(\**attr)
+
+   Replaces the current style for all nodes
+
+
+.. method:: edge_style(head, tail, \**attr)
+
+   Sets the style of an edge to the given attributes. The edge will
+   be added to the graph when it isn't already present, but *head*
+   and *tail* must both be valid nodes.
+
+   See `Valid Attributes`_ for more information about the attributes.
+
+
+
+Emitting output
+...............
+
+.. method:: Dot.display([mode])
+
+   Displays the current graph via dotty.
+
+   If the *mode* is ``"neato"`` the dot file is processed with
+   the neato command before displaying.
+
+   This method won't return until the dotty command exits.
+
+.. method:: save_dot(filename)
+
+   Saves the current graph representation into the given file.
+
+   .. note::
+
+       For backward compatibility reasons this method can also
+       be called without an argument, it will then write the graph
+       into a fixed filename (present in the attribute :data:`Graph.temp_dot`).
+
+       This feature is deprecated and should not be used.
+
+
+.. method:: save_image(file_name[, file_type[, mode]])
+
+   Saves the current graph representation as an image file. The output
+   is written into a file whose basename is *file_name* and whose suffix
+   is *file_type*.
+
+   The *file_type* specifies the type of file to write, the default
+   is ``"gif"``.
+
+   If the *mode* is ``"neato"`` the dot file is processed with
+   the neato command before displaying.
+
+   .. note::
+
+       For backward compatibility reasons this method can also
+       be called without an argument, it will then write the graph
+       with a fixed basename (``"out"``).
+
+       This feature is deprecated and should not be used.
+
+.. method:: iterdot()
+
+   Yields all lines of a `graphviz`_ input file (including line endings).
+
+.. method:: __iter__()
+
+   Alias for the :meth:`iterdot` method.

+
+.. method:: Graph.forw_bfs(start[, end])

+   the forward parameter.
+
+   If the distance between all neighbouring nodes is 1 the hop number
+   corresponds to the shortest distance between the nodes.

+   every other node.
+
+.. method:: Graph.clust_coef(node)
+
+   Returns the local clustering coefficient of node.
+
+   The local cluster coefficient is the proportion of the actual number

+   Dijkstra's algorithm for shortest paths.
+
+   Find shortest paths from the  start node to all nodes nearer 
+   than or equal to the *end* node. The edge data is assumed to be the edge length.
+
+   .. note::
+
+       Dijkstra's algorithm is only guaranteed to work correctly when all edge lengths are positive.
+       This code does not verify this property for all edges (only the edges examined until the end
+       vertex is reached), but will correctly compute shortest paths even for some graphs with negative
+       edges, and will raise an exception if it discovers that a negative edge has caused it to make a mistake.
+
+
+.. function:: shortest_path(graph, start, end)
+
+   Find a single shortest path from the given start node to the given end node.
+   The input has the same conventions as :func:`dijkstra`. The output is a list 
+   of the nodes in order along the shortest path.

+:mod:`altgraph.GraphStat` --- Functions providing various graph statistics
+==========================================================================
+
+.. module:: altgraph.GraphStat
+   :synopsis: Functions providing various graph statistics
+
+The module :mod:`altgraph.GraphStat` provides function that calculate
+graph statistics. Currently there is only one such function, more may
+be added later.
+
+.. function:: degree_dist(graph[, limits[, bin_num[, mode]]])
+
+   Groups the number of edges per node into *bin_num* bins
+   and returns the list of those bins. Every item in the result
+   is a tuple with the center of the bin and the number of items
+   in that bin.
+
+   When the *limits* argument is present it must be a tuple with
+   the mininum and maximum number of edges that get binned (that
+   is, when *limits* is ``(4, 10)`` only nodes with between 4
+   and 10 edges get counted.
+
+   The *mode* argument is used to count incoming (``'inc'``) or
+   outgoing (``'out'``) edges. The default is to count the outgoing
+   edges.

+:mod:`altgraph.GraphUtil` --- Utility functions
+================================================
+
+.. module:: altgraph.GraphUtil
+   :synopsis: Utility functions
+
+The module :mod:`altgraph.GraphUtil` performs a number of more
+or less useful utility functions.
+
+.. function:: generate_random_graph(node_num, edge_num[, self_loops[, multi_edges])
+
+   Generates and returns a :class:`Graph <altgraph.Graph.Graph>` instance
+   with *node_num* nodes randomly connected by *edge_num* edges.
+
+   When *self_loops* is present and True there can be edges that point from
+   a node to itself.
+
+   When *multi_edge* is present and True there can be duplicate edges.
+
+   This method raises :class:`GraphError <altgraph.GraphError` when
+   a graph with the requested configuration cannot be created.
+
+.. function:: generate_scale_free_graph(steps, growth_num[, self_loops[, multi_edges]])
+
+    Generates and returns a :py:class:`~altgraph.Graph.Graph` instance that 
+    will have *steps*growth_n um* nodes and a scale free (powerlaw) 
+    connectivity. 
+    
+    Starting with a fully connected graph with *growth_num* nodes
+    at every step *growth_num* nodes are added to the graph and are connected 
+    to existing nodes with a probability proportional to the degree of these 
+    existing nodes.
+
+    .. warning:: The current implementation is basically untested, although
+       code inspection seems to indicate an implementation that is consistent
+       with the description at 
+       `Wolfram MathWorld <http://mathworld.wolfram.com/Scale-FreeNetwork.html>`_
+
+.. function:: filter_stack(graph, head, filters)
+
+   Perform a depth-first oder walk of the graph starting at *head* and
+   apply all filter functions in *filters* on the node data of the nodes
+   found.
+
+   Returns (*visited*, *removes*, *orphans*), where
+
+   * *visited*: the set of visited nodes
+
+   * *removes*: the list of nodes where the node data doesn't match
+     all *filters*.
+
+   * *orphans*: list of tuples (*last_good*, *node*), where 
+     node is not in *removes* and one of the nodes that is connected
+     by an incoming edge is in *removes*. *Last_good* is the
+     closest upstream node that is not in *removes*.

+   :synopsis: A graph of objects that have a "graphident" attribute.
+
+.. class:: ObjectGraph([graph[, debug]])
+
+   A graph of objects that have a "graphident" attribute. The
+   value of this attribute is the key for the object in the
+   graph.
+
+   The optional *graph* is a previously constructed
+   :class:`Graph <altgraph.Graph.Graph>`.
+
+   The optional *debug* level controls the amount of debug output
+   (see :meth:`msg`, :meth:`msgin` and :meth:`msgout`).
+
+   .. note:: the altgraph library does not generate output, the
+      debug attribute and message methods are present for use
+      by subclasses.
+
+.. data:: ObjectGraph.graph
+
+   An :class:`Graph <altgraph.Graph.Graph>` object that contains
+   the graph data.
+
+
+.. method:: ObjectGraph.addNode(node)
+
+   Adds a *node* to the graph.
+
+   .. note:: re-adding a node that was previously removed
+      using :meth:`removeNode` will reinstate the previously
+      removed node.
+
+.. method:: ObjectGraph.createNode(self, cls, name, \*args, \**kwds)
+
+   Creates a new node using ``cls(*args, **kwds)`` and adds that
+   node using :meth:`addNode`.
+
+   Returns the newly created node.
+
+.. method:: ObjectGraph.removeNode(node)
+
+   Removes a *node* from the graph when it exists. The *node* argument
+   is either a node object, or the graphident of a node.
+
+.. method:: ObjectGraph.createReferences(fromnode, tonode[, edge_data])
+
+   Creates a reference from *fromnode* to *tonode*. The optional
+   *edge_data* is associated with the edge.
+
+   *Fromnode* and *tonode* can either be node objects or the graphident
+   values for nodes.
+
+.. method:: removeReference(fromnode, tonode)
+
+   Removes the reference from *fromnode* to *tonode* if it exists.
+
+.. method:: ObjectGraph.getRawIdent(node)
+
+   Returns the *graphident* attribute of *node*, or the graph itself
+   when *node* is :data:`None`.
+
+.. method:: getIdent(node)
+
+   Same as :meth:`getRawIdent`, but only if the node is part
+   of the graph.
+
+   *Node* can either be an actual node object or the graphident of
+   a node.
+
+.. method:: ObjectGraph.findNode(node)
+
+   Returns a given node in the graph, or :data:`Node` when it cannot
+   be found.
+
+   *Node* is either an object with a *graphident* attribute or
+   the *graphident* attribute itself.
+
+.. method:: ObjectGraph.__contains__(node)
+
+   Returns True if *node* is a member of the graph. *Node* is either an
+   object with a *graphident* attribute or the *graphident* attribute itself.
+
+.. method:: ObjectGraph.flatten([condition[, start]])
+
+   Yield all nodes that are entirely reachable by *condition*
+   starting fromt he given *start* node or the graph root.
+
+   .. note:: objects are only reachable from the graph root
+      when there is a reference from the root to the node
+      (either directly or through another node)
+
+.. method:: ObjectGraph.nodes()
+
+   Yield all nodes in the graph.
+
+.. method:: ObjectGraph.get_edges(node)
+
+   Returns two iterators that yield the nodes reaching by
+   outgoing and incoming edges.
+
+.. method:: ObjectGraph.filterStack(filters)
+
+   Filter the ObjectGraph in-place by removing all edges to nodes that
+   do not match every filter in the given filter list
+
+   Returns a tuple containing the number of:
+   (*nodes_visited*, *nodes_removed*, *nodes_orphaned*)
+
+.. method:: ObjectGraph.edgeData(fromNode, toNode):
+   Return the edge data associated with the edge from *fromNode*
+   to *toNode*.  Raises :exc:`KeyError` when no such edge exists.
+
+   .. versionadded: 0.12
+
+.. method:: ObjectGraph.updateEdgeData(fromNode, toNode, edgeData)
+
+   Replace the data associated with the edge from *fromNode* to
+   *toNode* by *edgeData*.
+
+   Raises :exc:`KeyError` when the edge does not exist.
+
+Debug output
+------------
+
+.. data:: ObjectGraph.debug
+
+   The current debug level.
+
+.. method:: ObjectGraph.msg(level, text, \*args)
+
+   Print a debug message at the current indentation level when the current
+   debug level is *level* or less.
+
+.. method:: ObjectGraph.msgin(level, text, \*args)
+
+   Print a debug message when the current debug level is *level* or less,
+   and increase the indentation level.
+
+.. method:: ObjectGraph.msgout(level, text, \*args)
+
+   Decrease the indentation level and print a debug message when the
+   current debug level is *level* or less.
