 Python Driver
 -------------
 
 Once the fuzzer is ready and satisfies PASTIS constraints, it can be wrapped in a Python driver
 that will act as an interface between the fuzzer and the broker. For that, all the required objects
 and types have been defined in ``libpastis``. It notably provides a :py:class:`ClientAgent` object

 receives from the broker.
