// in the app setup:
dust.helpers.config = function (chunk, ctx, bodies, params) {
    var data = ctx.get('config');
    if (!data) return chunk;
    
    var str = JSON.stringify(data).replace("</script>", "<'+'/script>");
    str = "<script>function CONFIG() { return JSON.parse('"+str+"'); }</script>";
    
    return chunk.write(str);
};

// in the template:
{@config/}

// in the controller:
res.render('template', {
    config: {/*whatever*/}
});
