Left and right delimiter

jSmart.prototype.ldelim / jSmart.prototype.rdelim

You can change default delimiters { and } assigning jSmart.prototype.ldelim and jSmart.prototype.rdelim

<script>

    jSmart.prototype.ldelim = '<!--{';
    jSmart.prototype.rdelim = '}-->';

    var tpl = new jSmart('{$foo}:<!--{$foo}-->', {ldelim: '<!--{', rdelim: '}-->'}); //Or they can be passed locally and they would override delimiters passed by prototype.

    tpl.fetch({foo:'bar'});  //will return '{$foo}:bar'

script>
