def description
  prettify <<-EOD
    w[here]|bt|backtrace        Display stack frames.

    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.
