    Name	Description
    CURRENT_VERSION_ID	The major and minor version of the currently running application, as "X.Y". The major version number ("X") is specified in the app's app.yaml file. The minor version number ("Y") is set automatically when each version of the app is uploaded to App Engine. On the development web server, the minor version is always "1".
    AUTH_DOMAIN	The domain used for authenticating users with the Users API. Apps hosted on appspot.com have an AUTH_DOMAIN of gmail.com, and accept any Google account. Apps hosted on a custom domain using Google Apps have an AUTH_DOMAIN equal to the custom domain.
    INSTANCE_ID	Contains the instance ID of the frontend instance handling a request. The ID is a hex string (for example, 00c61b117c7f7fd0ce9e1325a04b8f0df30deaaf). A logged-in admin can use the id in a url: http://[INSTANCE_ID].myApp.appspot.com/. The request will be routed to that specific frontend instance. If the instance cannot handle the request it returns an immediate 503.
    SERVER_SOFTWARE	In the development web server, this value is "Development/X.Y" where "X.Y" is the version of the runtime. When running on App Engine, this value is "Google App Engine/X.Y.Z".
