在这些用例中，源代码控制负责跟踪文件（网络配置、文档和软件源代码）。我们所说的
跟踪
文件，是指源代码控制工具保存着文件记录、文件随时间发生的变更以及谁对文件做
了改动。如果对被跟踪的文件所做的某处改动出现了问题，那么可以恢复或回滚到该文件
的先前版本，撤销改变并返回到已知的良好状态。在某些情况下（取决于所使用的工具），
源代码控制工具可以让你更方便地与同事展开分布式协作。
8.2
源代码控制的好处
上一节间接地介绍了源代码控制工具的一些好处，下面我们从中挑选出几个具体之处来
谈谈。
8.2.1
跟踪变更
我们可以跟踪源代码控制工具所保存的文件变更。由于文件在任意时刻的状态都能够被查
看到，因此你可以相对容易地了解到究竟发生了
什么
变更。这一优点往往会被人忽视。当
你在处理冗长的网络配置文件时，如果能够
准确
地看到从一个版本到下一个版本的变化，
岂不是很有帮助？此外，大多数源代码控制工具还能添加与变更相关的元数据，比如为什
么要做出变更，或是参考某个议题（
issue
）或故障工单
（
trouble ticket
）。这种附加的元数
据在排除故障时也非常有用。
8.2.2
可审计性
源代码控制不仅能跟踪变更，还能跟踪是谁做出的变更。每一处变更以及变更人都会被记
录下来。在团队环境中，多个团队成员可能共同管理网络配置或服务器配置文件，因此这
一点会显得尤其有用。你再也不用追问“这是谁改动的？”源代码控制工具已经将其记录
在案了。
8.2.3
流程和工作流
源代码控制工具还可以帮助你和你的组织推行健康的流程和工作流。第 ...
