  -Use the templating syntax when you create an `nginx.conf` file to use with the NGINX buildpack. This templating syntax loads modules and binds to ports based on values known at launch time.

  ### <a id='env'></a> Environment Variables ###
  
  To use an environment variable, include `{{env "YOUR-VARIABLE"}}`. Replace YOUR-VARIABLE with the name of an environment variable. At staging and at launch, the value of the environment variable replaces the template syntax.
  
  For example, include the following in your `nginx.conf` file to enable or disable the GZipping of files served based on the environment variable `GZIP_DOWNLOADS`:
  
  ```
  gzip {{env "GZIP_DOWNLOADS"}};
  ```
  
  When you set the environment variable `GZIP_DOWNLOADS` to `off`, NGINX does not GZip files. When you set `GZIP_DOWNLOADS` to `on`, NGINX GZips files served.
  
  ### <a id='provided-modules'></a> Buildpack-Provided Modules  ###
  
  The nginx-buildpack v0.0.5 and later include the following built-in module:
  
  * Stream module: `ngx_stream_module.so`
  
  
negative.code: 
  Users can supply their own dynamic modules by placing them in the app directory and providing a relative path to the module in the `nginx.conf` file.
  
  To include a user-provided dynamic module, add `load_module PATH-TO-MODULE;` to your `nginx.conf` file. Replace PATH-TO-MODULE with the relative path to the user-provided module.
  
  For example, to use a module named `my_module.so` that is located within the `modules` directory, include the following in your `nginx.conf` file:
