 * ## 使用说明
 * ### 注意：本程序只转移 主题、帖子和版块，不转会员
 * 
 * 1. 将本文件上传到两个网站共同的服务器（只要支持两个站的数据库连接均可）
 * 2. 复制 xiunobbs 下的 conf/conf.php 到本目录，或者自己修改以下的引入路径
 * 3. 复制 flarum 下的 config.php 到本目录，或者自己修改以下的引入路径
 * 4. 执行 composer require s9e/text-formatter 安装转换的扩展
 * 5. 再执行 php xiuno2flarum.php 命令行进行转换即可
 * 
 * 注意：由于 Flarum 程序与 Markdown 兼容问题，本程序转换的数据支持不完美。
