Twitch Audio-Only Restreamer

This script takes a Twitch.tv username and restreams the audio on a local Icecast2 server, while the stream is online. Every 60 seconds, the availability of the Twitch stream is checked and the audio stream started accordingly. The mountpoint of the audio stream on Icecast is the Twitch username.

Example: Twitch username: restreamer --> URL: localhost:8000/restreamer

Can be easily modified to be usable for other streaming sites as well.
