      A lightweight configurable overlay volume/backlight/progress/anything bar
      for the X Window System. 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).
