----------------------------------------------------------------------

The $(MODULE_SUMMARY_opentracing) for $(MODULE_SUMMARY_PREFIX) has been installed.
To enable this module, add the following to /etc/nginx/nginx.conf
and reload nginx:

    load_module modules/ngx_http_opentracing_module.so;

Note that additional tracer plugins are required in order
to communicate with corresponding services (e.g. Zipkin, Jaeger).
This package includes the Jaeger dynamic tracer plugin:

    /usr/libexec/opentracing/libjaegertracing_plugin.so

Please refer to the module documentation for further details:
