+CAF Login Exception (version 1)
+
+To avoid forcing users to make the source code of their whole
+application available to non-users, I (Ian Jackson) have granted this
+exception as part of the licence of CGI::Auth::Flexible.
+
+When considering AGPLv3 section 13 "Remote Network Interaction" (or
+similar provisions in successor licences):
+
+If all interactions with the Program (other than interactions with the
+user authentication system) require user authentication, the
+provisions of that section apply only to interaction with the Program
+by authenticated users.
+
+This is an Additional Permission as contemplated by AGPLv3 section 7.
