Hello world example
-------------------

The following code example is the canonical "Hello world" program in Propeller::

    from propeller import Application, RequestHandler, Response

    class HomeHandler(RequestHandler):
        def get(self, request):
            return Response('Hello world')

    a = Application([
        (r'^/', HomeHandler),
    ])

    if __name__ == '__main__':
        a.run()

Save the file as ``hello.py`` and start your app::

    python hello.py
