phpcms首页的html模板是如何加载的呢
怎么看也没有看出来,它的入口文件是如何加载html首页模板的.
有一个basee.php类,好象负责加载的,但是里面有点看不懂它怎么载的呢

------解决思路----------------------
默认路由设置：caches/configs/route.php 'default'=>array('m'=>'content', 'c'=>'index', 'a'=>'init'),
执行流程：base.php -> m=content -> c=index -> a=init
路径：phpcms/modules/content/index.php 里面的 function init()
