Channels¶
The channels library provides a thread-safe way to subscribe to channels and receive messages, for event-driven programs.
Note
This documentation is just a place-holder. For now, the best way to learn how the Channels library works is to look at the test suite or the way it is used in the Open Dylan IDE.
