Content-based routing with RabbitMQ and Python

Is it possible with RabbitMQ and Python to do content-based routing?

The AMQP standard and RabbitMQ claims to support content-based routing, but are there any libraries for Python which support specifying content-based bindings etc.?

The library I am currently using (py-amqplib http://barryp.org/software/py-amqplib/) seems to only support topic-based routing with simple pattern-matching (#, *).
