-/**
- * A Trails_Controller is responsible for matching the unconsumed part of an URI
- * to an action using the left over words as arguments for that action. The
- * action is then mapped to method of the controller instance which is called
- * with the just mentioned arguments. That method can send the #render_action,
- * #render_template, #render_text, #render_nothing or #redirect method.
- * Otherwise the #render_action is called with the current action as argument.
- * If the action method sets instance variables during performing, they will be
- * be used as attributes for the flexi-template opened by #render_action or
- * #render_template. A controller's response's body is populated with the output
- * of the #render_* methods. The action methods can add additional headers or
- * change the status of that response.
