+This script is the wrapper that starts a loopback call with stubbed video in
+and out. It then analyses the video quality of the output video against the
+reference input video.
+
+It expect to be given the webrtc output build directory as the first argument
+all other arguments are optional.
+
+It assumes you have a Android device plugged in.
