7. Insert-sgml-header程式之□例

读者在撰写一份 Linux Documentation Project 文件时,可以使用下列程式来启动自动插入自订的页首。

透过一 mini-buffer,上述程式会要求读者提供一些或许必要的资讯。

它会先询问要输出的标题是什麽,若您没有提供,则页首就不会显现标题。再来是日期,作者,作者的电子邮件帐号与 home page (最後两项可随意填入)。

接著它会询问翻译者的名字。若无,请直接键入 Return。若有,程式就会接著询问译者的电子邮件帐号及 home page (同样也是随意填入)。

再来它会把您的输入存入 current buffer,包括任何您输入的资讯格式,及摘要和第一章的标签。之後它会将游标导向您要键入摘要的的地方。
