+"""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
