;; Version: 1.0
;; To start: `M-x git-status'
;;
;; TODO
-;; - portability to XEmacs
;; - diff against other branch
;; - renaming files from the status buffer
;; - creating tags
;; - fetch/pull
-;; - switching branches
;; - revlist browser
;; - git-show-branch browser
-;; - menus
+;;
+
+;;; 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.
