"""Pyro transport module for kombu.

Pyro transport, and Kombu Broker daemon.

Requires the :mod:`Pyro4` library to be installed.

Features
========
* Type: Virtual
* Supports Direct: Yes
* Supports Topic: Yes
* Supports Fanout: No
* Supports Priority: No
* Supports TTL: No

Connection String
=================

To use the Pyro transport with Kombu, use an url of the form:

.. code-block::

pyro://localhost/kombu.broker

The hostname is where the transport will be looking for a Pyro name server,
which is used in turn to locate the kombu.broker Pyro service.
This broker can be launched by simply executing this transport module directly,
with the command: ``python -m kombu.transport.pyro``

Transport Options
