| ;;; 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. | |
