说明：  目前，在Unix系统下运行的程序的界面大都比较死板，而且，在进行功能扩充时也不是很方便。那么，能不能设计一个象 Windows那样能够按照用户要求随意调整界面，功能扩充方便的程序呢？答案是肯定的。在用户需要进行功能扩充时，也无须改动源程序，只须对参数文件进行操作就可将新增功能挂到菜单上。
(Currently, the Unix operating system interface procedures Most rigid, but when conducting functional expansion is not very convenient. So, can Windows as a design as user requirements in accordance with random adjustment interface functions to facilitate the expansion process? The answer is yes. The user needs expanded functionality, without source changes, we need to document operating parameters can be linked to the new functional menu.)
