    '''
    Show pricing for a particular profile. This is only an estimate, based on
    unofficial pricing sources.

    CLI Examples:

    .. code-block:: bash

        salt-cloud -f show_pricing my-ec2-config profile=my-profile

    If pricing sources have not been cached, they will be downloaded. Once they
    have been cached, they will not be updated automatically. To manually update
    all prices, use the following command:

    .. code-block:: bash

        salt-cloud -f update_pricing <provider>
