Introduction
============

This is an asynchronous python interface to the Dropbox API, using the
Tornado IOLoop.  It is designed to be similar to the existing interfaces
in the `tornado.auth` module.

Example usage
=============
        
    class MainHandler(tornado.web.RequestHandler,
                      async_dropbox.DropboxMixin):
        @tornado.web.authenticated
        @tornado.web.asynchronous
        def get(self):
            self.dropbox_request(
                "api", "/1/metadata/sandbox/",
                access_token=self.current_user["access_token"],
                callback=self._on_metadata)

        def _on_metadata(self, response):
            response.rethrow()
            metadata = json.loads(response.body)
            self.render("main.html", metadata=metadata)
