"""Simple API for XML (SAX) implementation for Python.
This module provides an implementation of the SAX 2 interface;
information about the Java version of the interface can be found at
http://www.megginson.com/SAX/.  The Python version of the interface is
documented at <...>.
This package contains the following modules:
handler -- Base classes and constants which define the SAX 2 API for
           the 'client-side' of SAX for Python.
saxutils -- Implementation of the convenience classes commonly used to
            work with SAX.
xmlreader -- Base classes and constants which define the SAX 2 API for
             the parsers used with SAX for Python.
expatreader -- Driver that allows use of the Expat parser with SAX.
