The aim of this module is to provide a common base representation of python source code for projects such as pychecker, pyreverse, pylint.

it provides a compatible representation which comes from the `_ast` module.

it rebuilds the generated tree by recursively walking down the ast and building an extended ast (let's call it astng ;). the new node classes have additional methods and attributes for different usages. they include some support for static inference and local name scopes. furthermore, astng builds partial trees by inspecting living objects.

this package contains the python 3 version of logilab.astng.
