 <p>L'objectif est de développer, en particulier, du code Javascript afin de présenter des animations de fichiers SVG produits, en particulier, par MetaPost. Ce développement n'étant pas tout à fait prédéterminé, il sera constitué à partir de l'exploration de différents scénarios de présentation de ces animations et des modes de construction des fichiers SVG.</p>

+<p>Le fichier <code>SVGAnimation.js</code> contient le constructeur <code>Controle</code> qui est la base des <em>players</em>. S'il est invoqué directement, il fournit un contrôle <em>simpliste</em> de l'animation, comme cela a été vu <a href="#côté-javascript">ci-dessus</a>.</p>

+<p>Pour utiliser un <em>player</em> plus <em>sophistiqué</em>, il faut surcharger la méthode <code>Initialisation</code> de l'objet <code>Controle</code>. Pour plus de détails sur les <em>players</em>, nous vous invitons à consulter la page dédiée.</p>
+<p>L'idée que nous présentons ici est de construire un objet JavaScript qui mettra des boutons de contrôle (lecture, stop, etc.).</p>

Dans l'exemple ci-dessous, on « vide » la <code>div</code> <code>XXXX_message</code>, et on ajoute des boutons à la <code>div</code> <code>XXXX_boutons</code> qui réagissent aux <code>onclick</code> pour lancer les fonctions JavaScript adéquates définies dans le fichier <code>SVGAnimation.js</code>.</p>
