+# NOTE: divio/django-formtools is IDENTICAL to django/django-formtools except
+# that its Django requirement has been relaxed to >=Django>=1.6. This is because
+# this version of django CMS supports Django 1.6+. Internally, CMS will use
+# django.contrib.formtools when available, then look for the external version if
+# required. Unfortunately, SetupTools doesn't allow use to load the external
+# library when using Django 1.7+ only.
+#
+# Further note that dependency links do not work by default. Current versions of
+# Pip support it with the flag `--process-dependency-links`
+#
+# Remove these machinations in CMS v3.3 when Django 1.6 support is dropped.
