    # parses command line arguments into a single args variable

    def parse_arguments():

        parser = argparse.ArgumentParser()

        parser.add_argument('filename', action='store')

        parser.add_argument('filename', action='store', help='Provide the name of the file list/adjacency list')

        parser.add_argument('config', action='store')

        args = parser.parse_args()

        return args
