-# Guestbook with Namespaces
-
-This application implements the Python [Guestbook sample][7] but uses
-datastore namespaces to keep values in separate places.
-
-Guestbook is an example application showing basic usage of Google App
-Engine. Users can read & write text messages and optionaly log-in with
-their Google account. Messages are stored in App Engine (NoSQL)
-High Replication Datastore (HRD) and retrieved using a strongly consistent
-(ancestor) query.

-Manages the namespace for the application.
-
-This file presents ways an ISV (Independent Software Vendor) might use
-namespaces to distribute the guestbook application to different corporate
-clients. The original guestbook.py is left unchanged. Our namespace choosing
-hook is run when datastore or memcache attempt to resolve the namespace.
-When defined in appengine_config.py the lib_config mechanism substitutes this
-function for the default definition which returns None. This hopefully shows
-how easy it can be to make an existing app namespace aware.
-
-Setting _NAMESPACE_PICKER has the following effects:
-
-If _USE_SERVER_NAME, we read the server name
-foo.guestbook-isv.appspot.com and set the namespace.
-
-If _USE_GOOGLE_APPS_DOMAIN, we allow the namespace manager to infer the
-namespace from the request.
-
-If _USE_COOKIE, then the ISV might have a gateway page that sets a cookie
-called 'namespace' for example, and we read this cookie and set the namespace
-to its value. Note this is not a secure use of cookies.
-
-Other possibilities not implemented here include using a mapping from user to
-namespace and possibly setting a namespace cookie from this mapping. If the
-mapping is stored in datastore, we would probably not wish to look it up on
-every query.
