Sirius.py
This is a simple interface to a collection of classes which
serialize Python objects to XML and back.
The system is very lightweight and was not intended for complex XML
Usage:
xmlString = Sirius.serialize( pythonObj )
pythonObj = Sirius.deserialize( xmlString )
'''

def serialize( pyObject, root=None ) :
serializer = Py2XML()
return serializer.parse( pyObject, root )
