            #{short_description}

            Print the entire stack frame. Each frame is numbered; the most recent
            frame is 0. A frame number can be referred to in the "frame" command.
            "up" and "down" add or subtract respectively to frame numbers shown.
            The position of the current frame is marked with -->. C-frames hang
            from their most immediate Ruby frame to indicate that they are not
            navigable.
