    # WORKAROUND...
    # The python oauth2client library only loads the credential from an
    # on-disk cache the first time 'refresh()' is called, and doesn't
    # actually 'Force a refresh of access_token' as advertised.
    # This call will load the credential, and the call below will refresh
    # it as needed.  If the credential is unexpired, the call below will
    # simply return a cache of this refresh.

    # Most useful API ever:
    # https://www.googleapis.com/oauth2/v1/tokeninfo?access_token={at}
