+      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.
