thats what I think too.

This approach would definitely work. I managed to write quite a simple
parse routine myself:

    def __load(self, configfile):
        
        """ Initialises all variables (as read-in from configfile) """
	    
        configs = {}
        afile = file(configfile, 'rw')
        contents = afile.read().splitlines()
        for aline in contents:
           keyval = string.split(aline, '=')
           if len(keyval) > 1:
               configs[keyval[0]] = keyval[1]
        self.log.debug('properties read-in: %s ' % configs)
        return configs

And it returns a dictionary of all key-values pairs. Its not exactly
robust but it does the job :) 

anyway, thanks for your help!
