python3-echo - 0.5-2 main

Python Echo is a small library for attaching callback functions to property
state changes.
The main features of Echo are:
- A simple, property-like interface to monitor state changes.
- Decorator syntax to create callback property getter/setter methods,
similar to @property.
- Context managers to delay or ignore callback events.
- Helper functions to connect callback properties to GUI elements
(at the moment only Qt is supported).
