 =head1 DESCRIPTION
 
-Catalyst Controller.
+The Users controller is based on L<CatalystX::Controller::Auth>, see
+there for most of the functionality. Any localised parts are described
+below.
+
+This controller uses L<Catalyst::TraitFor::Controller::reCAPTCHA> to
+create and check a reCaptcha form shown on the C<register> form to
+help prevent spam signups.

+=head2 login with openid
+
+Logging in with openid/google requires two passes through the login
+action, on the 2nd pass the C<openid-check> value is passed in when
+the openid providing webserver links the user back to the stemmaweb
+site. This adaptation to the C<login> action sets the realm we are
+authenticating against to be C<openid> in this case.
