+    flask.ext
+    ~~~~~~~~~
+
+    Redirect imports for extensions.  This module basically makes it possible
+    for us to transition from flaskext.foo to flask_foo without having to
+    force all extensions to upgrade at the same time.
+
+    When a user does ``from flask.ext.foo import bar`` it will attempt to
+    import ``from flask_foo import bar`` first and when that fails it will
+    try to import ``from flaskext.foo import bar``.
+
+    We're switching from namespace packages because it was just too painful for
+    everybody involved.
