Greetings,
	I have a little confusion about python objects.  I am trying to share an 
object between C++ and my embedded python script.    To do this I have found 
little to no help from the Python docs or on the web as how to mirror a 
complex object between the two.  I have found that siplib the library that 
makes SIP work has the ability to map C++ objects to python and vis versa.
++++Reference Notes++++
sipMapCppToSelf

Name
sipMapCppToSelf -- Convert a C/C++ pointer to a Python instance

PyObject * sipMapCppToSelf(const void * cppPtr, PyObject * pyClass);

Description
If the C/C++ pointer is recognized and it is an instance of a sub-class of 
the expected class then the previously wrapped instance is returned. 
Otherwise a new Python instance is created with the expected class. The 
instance comes with a reference. 

Return Value
A pointer to the Python object instance (or Py_None if a NULL pointer was 
passed in). 

cppPtr -  A pointer to the C++ object. 
pyClass - The expected Python class. 
++++END++++

- From what I can tell in the code this pyClass is the class created by my 
module that is being called from the embedded script.  My question is how do 
a make a PyObject out of it?

In python i do this:
	from foo import *
	bar = foo()

I tried this in C++ but it seems not  to work:
	PyObject *object = PyModule_New("foo");

Am I mis understanding the documentation here?

Thanks
