最后一步是创建一个启动这个应用程序的主函数。

The last step is to create a main function that kicks off the application.

因为线程调度程序真的等同于“执行a，接着执行b，然后执行c，等等”的指令，所以要在主函数中创建一个完全并行的情况也不困难。

Since the thread scheduler really amounts to instructions to "do a, then do B, then do c, etc." it was not difficult to create an entirely parallel case in a main function.

我指明“这里是我的主函数，这里是我的程序内容。”

I'm saying "here comes my main function; here comes the guts of my program."
