A project with one programmer that takes about a week from start to finish probably can live without a VCS.

如果一个项目仅由一个程序员花了一周左右时间完成，那大概可以不需要VCS。

For example, when you are working on large projects, separating a class into more than one file enables more than one programmer to work on it at the same time.

例如，在处理大型项目时，通过将某个类拆分为多个文件，使多个程序员可以同时处理该类。
