| ;;; 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
 | |
| ;;  - portability to XEmacs
 | |
| ;;  - better handling of subprocess errors
 | |
| ;;  - hook into file save (after-save-hook)
 | |
| ;;  - diff against other branch
 | |
| ;;  - renaming files from the status buffer
 | |
| ;;  - creating tags
 | |
| ;;  - fetch/pull
 | |
| ;;  - switching branches
 | |
| ;;  - revlist browser
 | |
| ;;  - git-show-branch browser
 | |
| ;;  - menus
