Catalyst::view::tt is the catalyst view class for the template toolkit. your application subclass should inherit from this class. this plugin renders the template specified in $c->stash->{template}, or $c->request->match. the template variables are set up from the contents of $c->stash, augmented with template variable base set to catalyst's $c->req->base, template variable c to catalyst's $c, and template variable name to catalyst's $c->config->{name}. the output is stored in $c->response->output.
