;;; Commentary: |
|
|
|
;; This file contains an interface for the git version control |
|
;; system. It provides easy access to the most frequently used git |
|
;; commands. The user interface is as far as possible identical to |
|
;; that of the PCL-CVS mode. |
|
;; |
|
;; To install: put this file on the load-path and place the following |
|
;; in your .emacs file: |
|
;; |
|
;; (require 'git) |
|
;; |
|
;; To start: `M-x git-status' |
|
;; |
|
;; TODO |
|
;; - diff against other branch |
|
;; - renaming files from the status buffer |
|
;; - creating tags |
|
;; - fetch/pull |
|
;; - revlist browser |
|
;; - git-show-branch browser |
|
;; |
|
|
|
;;; Compatibility: |
|
;; |
|
;; This file works on GNU Emacs 21 or later. It may work on older |
|
;; versions but this is not guaranteed. |
|
;; |
|
;; It may work on XEmacs 21, provided that you first install the ewoc |
|
;; and log-edit packages. |
