今天在github博客 （https://blog.github.com/） 上看到消息，免费账号支持无限的私有仓库的，这绝对是一个福利。
GitHub Free now includes unlimited private repositories. For the first time, developers can use GitHub for their private projects with up to three collaborators per repository for free. Many developers want to use private repos to apply for a job, work on a side project, or try something out in private before releasing it publicly. Starting today, those scenarios, and many more, are possible on GitHub at no cost. Public repositories are still free (of course—no changes there) and include unlimited collaborators.
大意就是说 -- github支持免费用户，使用私有代码仓库，并且不限数量，但是多只有三个合作者。其他的变量。
