;;; Commentary:
|
||
|
|
||
|
;; Magit is an interface to the version control system Git,
|
||
|
;; implemented as an Emacs package. Magit aspires to be a complete
|
||
|
;; Git porcelain. While we cannot (yet) claim, that Magit wraps and
|
||
|
;; improves upon each and every Git command, it is complete enough to
|
||
|
;; allow even experienced Git users to perform almost all of their
|
||
|
;; daily version control tasks directly from within Emacs. While many
|
||
|
;; fine Git clients exist, only Magit and Git itself deserve to be
|
||
|
;; called porcelains.
