If you already have Git installed, you can get the latest development version via Git itself:

git clone git://git.kernel.org/pub/scm/git/git.git ［local dir］

If you have problems connecting (Git uses port 9418), you can try to access the repository over the HTTP protocol:

git clone http://www.kernel.org/pub/scm/git/git.git [local dir]


部分git操作
git clone git://github.com/mongodb/mongo.git
git tag -l(列出可用版本)
git checkout r1.4.1(切换到指定版本)
