This is a fork of amqplib which was originally written by Barry Pederson. It is maintained by the Celery project, and used by kombu as a pure Python alternative when librabbitmq is not available.

This library should be API compatible with librabbitmq. Differences from amqplib are:
* Supports draining events from multiple channels (Connection.drain_events).
* Support for timeouts.
* Channels are restored after channel error, instead of having to close the
connection.
* Support for heartbeats.
* Supports RabbitMQ extensions:
- Consumer Cancel Notifications.
- Publisher confirms.
- Exchange-to-exchange bindings: exchange_bind / exchange_unbind.
* Support for basic_return.
* Uses AMQP 0-9-1 instead of 0-8.
* Exposes the underlying socket as Connection.sock.
* Adds Channel.no_ack_consumers to keep track of consumer tags that set the
no_ack flag.
* Slightly better at error recovery.
