            model developed in Naginator_, and all of the Nagios types are generated using the
            same code and the same library.

            This type generates Nagios configuration statements in Nagios-parseable configuration
            files.  By default, the statements will be added to ``#{target}``, but
            you can send them to a different file by setting their ``target`` attribute.

            You can purge Nagios resources using the ``resources`` type, but *only*
            in the default file locations.  This is an architectural limitation.
