Very basic event publishing system
This package provides a simple event system. It provides an event publishing system and a very simple event-dispatching system on which more sophisticated event dispatching systems can be built. For example, a type-based event dispatching system that builds on zope.event can be found in zope.component.
This is the Python 3 library.
