"""Python Abstract Syntax Tree New Generation.
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 mimics the class defined in the python's _ast module with some
additional methods and attributes. New nodes instances are not fully
compatible with python's _ast.
Instance attributes are added by a
builder object, which can either generate extended ast (let's call
them astroid ;) by visiting an existent ast tree or by inspecting living
object. Methods are added by monkey patching ast classes.
Main modules are:
* nodes and scoped_nodes for more information about methods and
attributes added to different node classes
* the manager contains a high level object to get astroid trees from
source files and living objects. It maintains a cache of previously
constructed tree for quick access
* builder contains the class responsible to build astroid trees
