        // Last update: July 21, 2009
        //
        // [FR]
        // Permet de placer un chunk au début de la chaîne menant au modèle.
        // Avantage : permet de rediriger dynamiquement vers 
        // un dossier correspondant à un sous-site.
        //
        // Au final, la chaîne vers le modèle doit être complète,
        // incluant assets/templates si le modèle se trouve dans ces sous-dossiers.
        //
        // [EN]
        // Allows to use a chunk at the beginning of the path to the template file.
        // Benefit : useful to redirect to subsites.
        //
        // ---------------------------------------------
        // Example: 
        // To load template from "main_site_root/subsite1/assets/templates/subsite.tpl"
        // Put in the code text area of your template :
        // @FILE:{{subsite1_root}}/assets/templates/subsite.tpl
        //
        // where the subsite1_root chunk contains "subsite1" (without the quotes).
