RAT is a network audio tool that allows users to particpate in
audio conferences over the internet. These can be between two
participants directly, or between a group of participants on a
common multicast group.  RAT features sender based loss mitigation
mechanisms and receiver based audio repair techniques to compensate
for packet loss, and load adaption in response to host performance.

This is a stable branch version. Works with half-duplex casrd as well.
This is required mbone/relate.
