/**
* Dh_Locale 语言包类
*
* 系统语言包采用的是php-gettext模块.
* 如果模板使用的是smarty.使用了smarty-gettext插件.插件地址http://sourceforge.net/projects/smarty-gettext/
*  php-gettext的安装和使用(ubuntu平台下)
*  1 Installation of gettext package: sudo apt-get install php-gettext
*  2 Install locales: see all locales in the file vim /usr/share/i18n/SUPPORTED
*  3 设置文件目录结构;如: Locale/zh_CN/LC_MESSAGES 或者 Locale/en_US/LC_MESSAGES
*  4 如果是smarty模板(使用{t}你好{/t}标记)。生成.c格式的文件;如:php -q tsmarty2c.php  $file > text.c
*  5 生成.po格式的文件;xgettext -o Dh.po –join-existing –omit-header –no-location text.c
*  6 生成.mo格式的文件;msgfmt Dh.po -o Dh.mo
*  7 移动mo文件到相应的Locale/en_US/LC_MESSAGES文件夹下面
