"""

Py-notify is a Python package providing tools for implementing `Observer programming

pattern`_. These tools include signals, conditions and variables.

Signals are lists of handlers that are called when signal is emitted. Conditions are

basically boolean variables coupled with a signal that is emitted when condition state

changes. They can be combined using standard logical operators (*not*, *and*, etc.) into

compound conditions. Variables, unlike conditions, can hold any Python object, not just

booleans, but they cannot be combined.

For more verbose introduction, please refer to the tutorial_.
