| """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 extends class defined in the python's _ast module with some |
| additional methods and attributes. Instance attributes are added by a |
| builder object, which can either generate extended ast (let's call |
| them astng ;) 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 astng 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 astng trees |
