import argparse


def copyfiles(src, dest):
    print("Copying from %s to %s" % (src, dest))


if __name__ == "__main__":
    parser = argparse.ArgumentParser()
    parser.add_argument("src_dir", metavar="src-dir", help="Where we are copying from")
    parser.add_argument("dest_dir", metavar="dest-dir", help="Where we are copying to")
    settings = parser.parse_args()
    copyfiles(settings.src_dir, settings.dest_dir)
