"""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 interface classes and functions:

ContentHandler, ErrorHandler - base classes for SAX2 handlers
SAXException, SAXNotRecognizedException,
SAXParseException, SAXNotSupportedException - SAX exceptions

make_parser            - creation of a new parser object
parse, parseString     - parse a document, using a provided handler
