        Introduction
        ------------
        
        `carrot` is a messaging queue framework for `Django_`, built on top of
        `py-amqplib`_. Before you start playing with ``carrot``, you should
        read the excellent article on RabbitMQ under python by Jason: `Rabbits and
        warrens`_.

        Installation
        -------------
        
        You can install ``carrot`` either via the Python Package Index (PyPI)
        or from source.
        
        To install using ``pip``:
        
        ::
        $ pip install carrot
        
        To install using ``easy_install``
        
        $ easy_install carrot
        
        If you have downloaded a source tarball you can install it
        in the following way:
        ::
        $ python setup.py build
        # python setup.py install # as root
        
        
        Example
        -------
        
        This is a `carrot` implementation of the example publisher and
        consumer described in the article `Rabbits and warrens`_
        
        >>> from carrot.messaging import Publisher, Consumer
        
        >>> class PostOfficePublisher(Publisher):
        ...     exchange = "sorting_room"
        ...     routing_key = "jason"
        
        >>> class PostOfficeConsumer(Consumer):
        ...     queue = "po_box"
        ...     exchange = "sorting_room"
        ...     routing_key = "json"
        ...
        ...     def receieve(self, message_data, message):
        ...         """This is the method that is called whenever we
        ...         receieve a message in this queue."""
        ...         print("Received: %s" % message_data)
        
        By default every message is encoded using `JSON`_, if you don't want
        this you have to set the ``encoding`` attribute in the producer and
        the ``decoding`` attribute in the consumer to ``lambda x: x``.
        
        There are lots of other options for producers and consumers for which
        the only documentation right now is the source code (sorry!)
        
        To start sending and receveing messages with these classes, you first
        have to configure the AMQP server for your django app. If you have a
        `RabbitMQ`_ server running on localhost you can add these settings
        to your ``settings.py``:
        
        ::
        AMQP_SERVER = "localhost"
        AMQP_PORT = 5678
        AMQP_USER = "my_rabbitmq_user"
        AMQP_PASSWORD = "my_rabbitmq_user_password"
        AMQP_VHOST = "virtual_host_to_use"
        
        
        Then, finally, we can send and receive some messages:
        
        >>> PostOfficePublisher().send({"My message": ["foo", "bar", "baz"]})
        >>> PostOfficeConsumer().next()
        Receieved: {"My message": ["foo", "bar", "baz"]}
