Catalyst::action::renderview module implements a sensible default end action for catalyst, which will forward to the first available view, unless $c->res->status is a 3xx code (redirection, not modified, etc.), 204 (no content), or $c->res->body has already been set. it also allows you to pass 'dump_info=1' to the url in order to force a debug screen, while in debug mode.

catalyst is an elegant model-view-controller web application framework written in perl.
