+     Provides a publish-subscribe API to facilitate event-based or

+     Python  and works on Python 3.3+. It is centered on the notion of a topic;
+     senders publish messages of a given topic, and listeners subscribe to
+     messages of a given topic, all inside the same process. The package also
+     supports a variety of advanced features that facilitate debugging and
+     maintaining topics and messages in larger desktop- or server-based
+     applications.
