Stupid simple API reference for bottle.py web services

bottle.py python

I have a stupid json-only REST API I implemented in bottle.py. This introspects the default app, gives a dumb readout that should act as an adequate reference for discovery:

@bottle.route('/')
def index():
    bottle.response.content_type = 'text/plain'
    return ("=== API REFERENCE ===\n" +
            "\n".join(x['rule'] for x in
                      bottle.app().routes))
