;;; Commentary:
;; Invoking the magit-status function will show a buffer with the
;; status of the current git repository and its working tree. That
;; buffer offers key bindings for manipulating the status in simple
;; ways.
;;
;; The status buffer mainly shows the difference between the working
;; tree and the index, and the difference between the index and the
;; current HEAD. You can add individual hunks from the working tree
;; to the index, and you can commit the index.
;;
;; See the Magit User Manual for more information.
