      libcaca is a graphics library that outputs text instead of pixels, so that
      it can work on older video cards or text terminals. It is not unlike the
      famous ​AAlib library, with the following improvements:

      - Unicode support
      - 2048 available colours (some devices can only handle 16)
      - dithering of colour images
      - advanced text canvas operations (blitting, rotations)

      Libcaca works in a text terminal (and should thus work on all Unix systems
      including Mac OS X) using the S-Lang or ncurses libraries. It also works
      natively on DOS and Windows.

      Libcaca was written by Sam Hocevar and Jean-Yves Lamoureux.
