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

The $(MODULE_SUMMARY_lua) for $(MODULE_SUMMARY_PREFIX) have been installed.
To enable these modules, add the following to /etc/nginx/nginx.conf
and reload nginx:

    load_module modules/ndk_http_module.so;
    load_module modules/ngx_http_lua_module.so;
    load_module modules/ngx_stream_lua_module.so;

Note that ndk_http_module.so must be placed first.

These modules are compiled with LuaJIT 2.1 library.
The following binary should be used for testing and bytecode generation:

    /usr/bin/nginx-luajit

Please refer to the modules documentation for further details:
