    Exchange
    --------

    Example creating an exchange declaration::

        >>> news_exchange = Exchange('news', type='topic')

    For now `news_exchange` is just a declaration, you can't perform
    actions on it. It just describes the name and options for the exchange.

    The exchange can be bound or unbound. Bound means the exchange is
    associated with a channel and operations can be performed on it.
    To bind the exchange you call the exchange with the channel as argument::

        >>> bound_exchange = news_exchange(channel)

    Now you can perform operations like :meth:`declare` or :meth:`delete`::

        >>> bound_exchange.declare()
        >>> message = bound_exchange.Message('Cure for cancer found!')
        >>> bound_exchange.publish(message, routing_key='news.science')
        >>> bound_exchange.delete()

    .. autoclass:: Exchange
        :members:
        :undoc-members:

        .. automethod:: maybe_bind

    Queue
    -----

    Example creating a queue using our exchange in the :class:`Exchange`
    example::

        >>> science_news = Queue('science_news',
        ...                      exchange=news_exchange,
        ...                      routing_key='news.science')

    For now `science_news` is just a declaration, you can't perform
    actions on it. It just describes the name and options for the queue.

    The queue can be bound or unbound. Bound means the queue is
    associated with a channel and operations can be performed on it.
    To bind the queue you call the queue instance with the channel as
    an argument::

        >>> bound_science_news = science_news(channel)

    Now you can perform operations like :meth:`declare` or :meth:`purge`:

    .. code-block:: python

        >>> bound_science_news.declare()
        >>> bound_science_news.purge()
        >>> bound_science_news.delete()

    .. autoclass:: Queue

        :undoc-members:

        .. automethod:: maybe_bind
