Thanks for the suggestion. This way to do is new to me, and I didn't 
come to the idea myself. It seems like a good way to do this. But how to 
give an argument to this config namespace? i.e I want "app.conf" to be 
given as argument.

Currently my program starts like this:

def main():

     # See if the user gave a configfile
     if len(sys.argv) == 2:
         # file was given as argument
         cfg = str(sys.argv[1])
     else:
         # default file taken in the resource directory
         cfg = os.path.abspath(os.path.join(os.path.dirname(__file__),
                               os.pardir,'res','default.cfg'))

     obj = superobj(cfg)
     obj.preprocess()
     obj.process()
     obj.write()
