django-compressor on google app engine

Small tip: django-compressor requires that your static folder is readable by the application. This is configured in your app.yaml:

handlers:
- url: /static
  static_dir: static
  application_readable: True

Otherwise you'll get an empty manifest.json file, which means offline compressed files are not found.
