<?php
/*
 * buildcomb.php用于将代码中使用了smartcomb.php?type=xxx&modules=aa,bb 的地方替换成一个静态文件的引用
 * 使用方法： php buildcomb.php -target the/path -ext html,php -exclude xxx.html
 *  target: 目标文件夹，默认是当前文件夹 需要确保文件夹中有且只有一个smartcomb.php文件
 *  ext: 需要替换的文件后缀，默认html,多个以,分隔
 *  exclude: 需要排除的文件,只要文件路径中含有该字符串就会排除，多个以,分隔
 *
 *  删除生成的文件 ls  | grep '[a-z0-9]\{32,32\}.\(js\|css\)' | xargs rm
