Documentation

Overview

Requests are sent through channels for communication. It works like a mail system, every routine shares a channel which is regarded by themselves as a outport and they send out their requests for routines outside through it. And every routine holds a channel from where they receive outside requests. Thus a mail routine(usually main routine) is required to listen to the shared channel and dispatch requests there to their destination.
