  /testconfigid:[config id]         The id (a positive integer) of the
                                    pre-existing test management configuration
                                    to associate with the published run.
                                    If not specified using an id then 
                                    optionally use /testconfigname to specify
                                    the configuration by name. If you use 
                                    neither then no configuration will 
                                    be associated with the published run.
                                    This switch is only used with /publish 
                                    to publish to a test management server.
