      A lightweight configurable overlay volume/backlight/progress/anything bar
      for the X Window System (and Wayland compositors with XWayland). Each
      time a new value is read on the standard input, it is displayed as a
      tv-like bar over other windows. It then vanishes after a configurable
      amount of time. A value followed by a bang '!' is displayed using an
      alternate color to account for special states (e.g. muted audio). There
      is also support for overflows (when the value exceeds the maximum).
