Small little script to retrieve the keywords from any web page.
You can either pass the url for the page as an argument or enter
it when prompted for it.

Example:
    keywords.py https://www.youtube.com/watch?v=YrHlHbtiSM0

The keywords get printed to the console and are also copied to
your system's clipboard and are ready to paste.
