ecs_shop_config -> 商店配置(template, stylename)
load_config() -> lib_common.php
includes/init.php 文件做了 smarty 文件初始化：
require(ROOT_PATH . 'includes/cls_template.php');
$smarty = new cls_template;
assign_template() 函数封装在 lib_main.php
strrchr($haystack, $needle);

<!-- #BeginLibraryItem "...." -->
<!--\s#EndLibraryItem\s-->
编译成为 {include file="..."}.
