+The aim of this module is to provide a common base representation of
+python source code for projects such as pychecker, pyreverse,
+pylint... Well, actually the development of this library is essentially
+governed by pylint's needs. It used to be called logilab-astng.
+
+It provides a compatible representation which comes from the `_ast`
+module. It rebuilds the tree generated by the builtin _ast module by
+recursively walking down the AST and building an extended ast. The new
+node classes have additional methods and attributes for different
+usages. They include some support for static inference and local name
+scopes. Furthermore, astroid builds partial trees by inspecting living
+objects.
