      今天在学习Uboot的时候，发现了一个很有趣的东西，起初我还以为那是一些伪代码，后来仔细一看才发现，原来那是作者写给读者的一段话。不管怎样，我还是想分享一下。Adam Smith说分享是本性，我也这么想。

先给你们看一小段：

void no_more_time (int sig)
{
      hire_a_guru(); 
}

我想你现在肯定是把它当做C代码来读了，可事实并非如此。

事实是作者在对你说：你要是没有时间去学习怎么使用Uboot，可是你又必须得使用Uboot，那么你就去雇佣Guru吧！(我还误以为是Gru：卑鄙的我中的男主角)

如果它能勾起你的好奇心，就读读原文吧，体会一下别样的幽默。
