[DEPRECATED] Google App Engine web.py demo application
This application is a demo of Google App Engine and using the web.py framework on that platform. If you are interested in using web.py on GAE, this would be an ideal starting point.
I have included:
Install
Grab the App Engine SDK:
http://code.google.com/appengine/downloads.html
Then run the demo via:
$ cd gae-webpy-demoapp $ dev_appserver.py .
