Signature for a module that Picos_lwt.run requires for interoperating with the system that Lwt runs on.

run (module System) main runs the main program implemented in Picos as a promise with Lwt as the scheduler using the given System module. In other words, the main program will be run as a Lwt promise or fiber.
