Multicast DNS Service Discovery for Python

Authors:	Originally by Paul Scott-Murphy modified by William McBrine
Version:	0.14-wmcbrine

zeroconf.py is the implementation file; look at the end for examples of basic use. You can also view zwebbrowse.py to see how to browse for services, and zwebtest.py for an example of announcing them.

This fork is used in all of my TiVo-related projects: HME for Python (and therefore HME/VLC), Network Remote, Remote Proxy, and pyTivo. Before this, I was tracking the changes for zeroconf.py in three separate repos. I figured I should have an authoritative source.

Although I make changes based on my experience with TiVos, I expect that they're generally applicable. This version also includes patches found on the now-defunct (?) Launchpad repo of pyzeroconf, and elsewhere around the net -- not always well-documented, sorry.

Long-term goals: Python 3.x
