GIT: never lose code
Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.
Git is easy to learn and has a tiny footprint with lightning fast performance. It outclasses other SCM(source code mgmt) tools with features like cheap local branching, convenient staging areas, and multiple workflows.
