safelinks keeps getting mentioned.

Here:

    #!/usr/bin/env python3
    from urllib.parse import urlparse, parse_qs
    from sys import argv
    print(parse_qs(urlparse(argv[1]).query)['url'][0])

This is unsafelinks. Pass it a safelinks url, and it will print the original URL. Very important when you have a one-time-use link which safelinks can break.
