Git is a free and open source distributed version control system designed to handle everything from small to very large projects.
It outclasses SCM tools like Subversion, CVS, Perforce, and ClearCase with features like cheap local branching, convenient staging areas, and multiple workflows.
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. This package itself only provides the README of git but with the packages it requires, it brings you a complete Git environment including GTK and email interfaces and tools for importing source code repositories from other revision control systems such as subversion, CVS, and GNU arch.
