embedded python in c++ packaging

I've done this the rather old-fashioned way.
Basically, what I do is:
Step 1:
Embed Python:
  init_memoryhoginterface();  // This initializes your SWIG module 
  PyRun_SimpleString("print 'HELLO FROM PYTHON'");  //<--- OR you can do something else here like run a file
Step 2: 
Extend python to talk back to your C++ code. 
I use one giant SWIG module (see init function above)
SWIG allows you to finely control what you expose to python, so you don't wind up exposing the whole C++ API.

I do not have access to my development machine right now.
but is it enough adding just a simple line at the top of my main python file 'sys.path.append("modules.zip")' before importing any other modules?

	Using py2exe has an additional advantage, it recursively scans all modules
	looking for dependencies.
	Once you know the required set of modules, you can bundle them in a .zip
	file and add its full path into sys.path (the absolute path including
	filename and .zip extension). Python does look into the .zip searching for
