|Description||Version control front end for emacs|
|Part of Emacs||yes|
vc is a Version Control minor mode. This minor mode is automatically activated whenever a file is opened which is under any revision control system. It supports many different version control systems including git, bazaar, CVS and SVN etc. It gives a unique interface to Emacs irrespective of back end version control system in operation.
No particular setup is needed for basic usage. Emacs checks for usage of version control automatically when a file is being opened.

Automatically revert version-controlled buffers
Since version controlled files tend to be changed outside of Emacs, it might be useful to automatically activate auto-revert-mode.
