"""An example usage of cratonclient when working with Craton and Keystone.

Requires:

    - Craton to be configured using Keystone for identity (configuring
      etc/craton-api-conf.sample [keystone_authtoken] section and
      etc/craton-api-paste.ini to use keystoneauthcontext)

      etc/craton-api-conf.sample should include something that looks like:

      .. code-block:: ini

            # etc/craton-api-conf.sample
            [keystone_authtoken]
            auth_host = 127.0.0.1
            auth_port = 5000
            auth_version = 3
            auth_protocol = http
            project_name = service
            username = craton
            password = craton
            project_domain_id = default
            user_domain_id = default
            auth_type = password

      While etc/craton-api.paste.ini should include something that looks like:

      .. code-block:: ini

            [pipeline:main]
            pipeline = request_id keystonecontext api_v1

    - Installing python-cratonclient
