ZipMe : Download sources of your GAE website, as a zip file

This is just a simple app script, called "zipme", you must put into your account, at the root of the folder. Just add this lines in your app.yaml :

- url: /zipme
  script: zipme.py

And with your favorite browser, go to your gae account http:// your_host/zipme, and it will download all your source in a zip file. Of course, you'll need to be logged in as an admin, to be able to get the download.

This source is released in the Public domain :
