If you mimic a tipical Python installation layout in your application  
(don't have to include everything, only what you need) and you call  
Py_SetProgramName at the very beginning of your program, then the default  
rules for building sys.path will work.
(Mmm, I can't find out where exactly those rules are explained).

Looks like PyRun_InteractiveOne and PyRun_InteractiveLoop should work for  
you, but I've never used them.
