MODULE_DESCRIPTION = """\
This module installs and configures ``landscape-client``. The landscape client
will only be installed if the key ``landscape`` is present in config. Landscape
client configuration is given under the ``client`` key under the main
``landscape`` config key. The config parameters are not interpreted by
cloud-init, but rather are converted into a ConfigObj formatted file and
written out to the `[client]` section in ``/etc/landscape/client.conf``.

The following default client config is provided, but can be overridden::

    landscape:
        client:
            log_level: "info"
            url: "https://landscape.canonical.com/message-system"
            ping_url: "http://landscape.canoncial.com/ping"
            data_path: "/var/lib/landscape/client"

.. note::
    see landscape documentation for client config keys

.. note::
    if ``tags`` is defined, its contents should be a string delimited with
    ``,`` rather than a list
