"""
The proton module defines a suite of APIs that implement the AMQP 1.0
protocol.

The proton APIs consist of the following classes:

 - :class:`Message`    -- A class for creating and/or accessing AMQP message content.
 - :class:`Data`       -- A class for creating and/or accessing arbitrary AMQP encoded data.
