+"""
+This is an attempt at bridging matrix clients into a Jitis meet room via Matrix
+video call.  It uses hard-coded xml strings overg XMPP BOSH. It can display one
+of the streams from the Jitsi bridge until the second lot of SDP comes down and
+we set the remote SDP at which point the stream ends. Our video never gets to
+the bridge.
+
+Requires:
+npm install jquery jsdom
