 ## Usage
 
 Here is an async HTTP server built with just the event loop.

 **Note:** The factory is just for convenience. It tries to pick the best
 available implementation. Libraries `SHOULD` allow the user to inject an
 instance of the loop. They `MAY` use the factory when the user did not supply
