  """Configure contact settings of a Cloud Domains registration.

  Configure registration's contact settings: email, phone number, postal
  address and also contact privacy.

  In some cases such changes have to be confirmed through an email sent to
  the registrant before they take effect. In order to resend the email, execute
  this command again.

  ## EXAMPLES

  To start an interactive flow to configure contact settings for
  ``example.com'', run:

    $ {command} example.com

  To enable contact privacy for ``example.com'', run:

    $ {command} example.com --contact-privacy=private-contact-data

  To change contact data for ``example.com'' according to information from a
  YAML file ``contacts.yaml'', run:

    $ {command} example.com --contact-data-from-file=contacts.yaml
