This has the same effect as POSTing a document to the [/load](#post-load) endpoint, but is convenient for simple workflows revolving around config files. Since the admin endpoint is configurable, the endpoint configuration is loaded from the `--address` flag if specified; otherwise it is loaded from the given config file; otherwise the default is assumed.
