Travis tells us about distributed version control in general, when to use it -- and when not to.He also describes how Git works, and walks through the daily Git workflow. Travis reminds us that code is never perfect, and describes how to track changes in a distributed environment. He'll show how to selectively push repositories to different people on your team, and how to use gitosis.
