This script launches the Django and Tornado servers, then runs a reverse proxy

which serves to both of them. After it's all up and running, browse to

http://localhost:9991/

Note that, while runserver and runtornado have the usual auto-restarting

behavior, the reverse proxy itself does *not* automatically restart on changes

to this file.
