说明：  • Repo是google用Python脚本写的调用git的一个脚本，主要是用来下载、管理Android项目的软件仓库； • 从高通或google下载代码是通过repo下载的，是由repo管理的266个git组成的 • l现在使用的git库是将由repo管理266个小git合并成一个git库导入 • 目前导入的repo是将项目定制化的内容取出，拆成由repo管理45个小git；
(Repo is a tool that we built on top of Git. Repo helps us manage the many Git repositories, does the uploads to our revision control system, and automates parts of the Android development workflow. Repo is not meant to replace Git, only to make it easier to work with Git in the context of Android. The repo command is an executable Python script that you can put anywhere in your path. )
