From 400cf5658da46fc748e64a7570a6df0dd21cbff2 Mon Sep 17 00:00:00 2001
From: Jacob Kaplan-Moss <jacob@jacobian.org>
Date: Tue, 15 Nov 2005 17:19:33 +0000
Subject: Added django.views.generic.simple.redirect_to view for issuing simple
 redirects.  Also updated direct_to_template to use render_to_response to be
 consistant with coding style, and documented the simple generic views.
