        try {
            // ex: http://www.youtube.com/watch?v=Nj6PFaDmp6c
            String url = args[0];
            // ex: "/Users/axet/Downloads"
            String path = args[1];
            VGet v = new VGet(new URL(url), new File(path));
            v.download();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

}
