2、测试程序

<font size="2"><font face="verdana,arial,helvetica">PHP代码:</font><hr></font><code><font color="#000000">

</code><hr>

3、使用说明
我懒得打了，对比一下"plugins.html"的5个{page}用法，以及看看显示出来的效果就明白是什么了

4、插件说明
“《Smarty手册》第十六章.以插件扩展Smarty ”的应用。像中文字符截取之类的都可以以plugins扩展Smarty，Smarty自带的截取不支持中文。

二、Smarty自动生成静态页面
如果你的文件扩展名为".html"~~~~~嘿嘿，这不就是静态页面了吗？-_-!

至于怎么取得静态的文件名呢？
