[web2py] How to deploy on gae with example.appspot.com directly map to my application?

[jinlin]

I saw the py2web.appspot.com directly map to the reddish application,
and I want to do the same for my deployment.

I already deployed the cookbook application tutorial to
http://tempappz.appspot.com/cookbook/test , how do I shorten the url
so my application is mapped directly from http://tempappz.appspot.com/

Is the changes in the app.yaml url mapping or in the py2web routing?

Thanks
