     24<h1> libcaca - Colour AsCii Art library </h1>
     25
     26<p class="right"> <i>it’s da shit!</i> </p>
     27
     28<p> The libcaca library is a graphics library that outputs text instead of
     29pixels, so that it can work on older video cards or text terminals. It is not
     30unlike the famous <a href="http://aa-project.sourceforge.net/aalib/">AAlib</a>
     31library, with the following improvements:
     32
     33<ul>
     34  <li> Unicode support </li>
     35  <li> 4096 available colours (some devices can only handle 16) </li>
     36  <li> dithering of colour images </li>
     37  <li> advanced text canvas operations (blitting, rotations) </li>
     38</ul>
     39
     40<p> Libcaca works in a text terminal (and should thus work on all Unix
     41systems including Mac OS X) using the S-Lang or ncurses libraries. It also
     42works natively on DOS and Windows.
     43
     44<p> Libcaca is <a href="http://www.gnu.org/philosophy/free-sw.html">free
     45software</a>, and can be used, modified and ditributed under the terms of the
     46<a href="http://sam.zoy.org/wtfpl/">Do What The Fuck You Want To Public
     47License</a>. The logo on this page is copyrighted by Akira Toriyama so if
     48anyone fancies drawing a new logo it would be much appreciated. </p>

     374Que dites-vous ?... C’est inutile ?... Je le sais !
     375<br />Mais on ne se bat pas dans l’espoir du succès !
     376<br />Non ! non, c’est bien plus beau lorsque c’est inutile !

     380<p> I am perfectly aware that libcaca is the waste of time it looks to be. No
     381need to tell me about that. I urge you to read Théophile Gautier’s preface to
     382<i>Mademoiselle de Maupin</i>, which also gives an excellent explanation for
     383the name “libcaca”: </p>
     384
     385<blockquote><p>
     386Il n’y a rien de vraiment beau que ce qui ne peut servir à rien ; tout ce
     387qui est utile est laid ; car c’est l’expression de quelque besoin ; et ceux
     388de l’homme sont ignobles et dégoûtants, comme sa pauvre et infirme nature. -
     389L’endroit le plus utile d’une maison, ce sont les latrines.

     392<p> As for the name “libcucul”, please refer to the pioneer of modernist
     393Polish fiction: </p>

     395<blockquote><p>
     396Mais contre le cucul, il n’y a pas de refuge. Courez après moi
     397si vous voulez, je m’enfuis la gueule entre les mains. Et voilà,
     398tralala, Zut à celui qui le lira !
