git-el 1:2.1.0-1 (amd64 binary) in ubuntu vivid

 Git is popular version control system designed to handle very large
 projects with speed and efficiency; it is used for many high profile
 open source projects, most notably the Linux kernel.
 .
 Git falls in the category of distributed source code management tools.
 Every Git working directory is a full-fledged repository with full
 revision tracking capabilities, not dependent on network access or a
 central server.
 .
 This package provides two modules for integration with Emacs:
 .
  * git.el:
 .
    Status manager that displays the state of all the files of the
    project and provides easy access to the most frequently used git
    commands. The user interface is intended to be similar to the
    pcl-cvs mode. It can be started with `M-x git-status'.
 .
  * git-blame.el:
 .
    Emacs implementation of incremental "git blame". When you turn it
    on while viewing a file, the editor buffer will be updated by
    setting the background of individual lines to a color that reflects
    which commit it comes from.
 .
 This package does not contain the VC-mode backend for git. That is
 part of standard Emacs distributions, starting with version 22.2.
 .
 For a more polished Emacs interface for Git, see the magit package.
