TL;DR: 什么时候要用再看吧…也许现在你的兴趣并不大

把这篇文章里的命令打完，就能明白git submodule了 http://git-scm.com/book/en/Git-Tools-Submodules

Submodules are for things such as commonly reused libraries. It should be self-contained.

要点：

1. submodule在添加或改动时，在主文件夹内commit，会产生特别的submodule型changeset.
2. git submodule update负责把submodule的HEAD移动到最近的submodule型changeset里记录的SHA的节点
