At this point we build again, but this time on an integration machine based on the mainline code.

我需要再次构建，但这次是在一台拥有主线代码的集成机器上进行。

It? S simply the concept of mainline code that calls out to functions or subroutines that each implement an individual piece of a larger program.

它只不过就是调用函数或者子例程的主线代码的概念，其中每个函数或者子例程实现了更大的程序的一个单独的部分。

When a team develops in parallel, it's important to merge code back to the mainline (trunk) as often as feasible.

团队进行并行开发时，一定要以最高的频率将代码合并回干线(即主干)。
