+# Le composant permet d'ajouter un comportement de tremblement ? un objet cible
+#
+# Parametres : 
+#	* target : objet cible du tremblement
+#	* %options : table de hash permettant la configuration initiale des proprietes
+# Propriete :
+#	* timeout : periode / 2 du tremblement
+#	* target : cible
+# 	* amplitude_x, amplitude_y : amplitude du deplacement
+#	* -visible : visibilite versus activation du comportement
