git 设置 用户名和信箱

Guides: Tell git your user name and email address 
Git needs to know your username and email address to properly tag your commits. This is normally done on a global level:

[~]$ git config --global user.name "lubin"
[~]$ git config --global user.email [e-mail]
You can override these settings on a per-repo basis:

[~/path/to/repo]$ git config user.name "lubin"
[~/path/to/repo]$ git config user.email [e-mail]
This change will only affect future commits. Past commits will retain the username and address they were committed with.

Some tools will assume your github config is in the same place (http://github.com/blog/180-local-github-config):

[~]$ git config --global github.user lubin
[~]$ git config --global github.token 6ef8395fecf207165f1a82178ae1b984
