Research direction

The reported entry points are nginx -V, nginx.conf, the load_module path, and nginx -t; start by comparing the nginx build version with the downloaded module's reported version. Done means establishing a compatible module and nginx build combination and verifying that nginx -t succeeds with the module loaded.
