Solve the following python programming problem given the following code:
def addOptions(parser, config = Config ()) : 
    '
    Adds toil options to a parser object, either optparse or argparse.
    ' 
    addLoggingOptions (parser) 
    if isinstance (addGroup, ArgumentParser) : 
        def addGroup(headingString, bodyString) : 
            return parser.add_argument_group (headingString, bodyString).add_argument 
_addOptions (addGroup, config) 
else : 
        raise RuntimeError (('Unanticipated class passed to addOptions(), %s. Expecting argparse.ArgumentParser' % parser.__class__))
