I understand, and I basicly would like to use the setuptools egg code.

This is a special and limited use-case:

The eggs do *not* need to be found by other eggs/applications, as they 
are used only by the application that loads them in.

Thus I just want to create the egg representation in my code (to call 
the entry_points), whilst using the information from setup.py/sources 
(instead of the generated egg_info).

Essentially, the code (internal in setuptools) that reads the egg_info 
will simply retrieve it from the setup.py (or i instantiate it somhow, 
and pass it to the setuptools routines)

The function would be essentially:

def get_an_egg(path_to_setuppy)
   # load setup.py
   # construct the egg
   return egg

#further processing based on standard egg methods
