;;; Commentary:
;; This package provides the tools meant to help editing PO files,
;; as documented in the GNU gettext user's manual. See this manual
;; for user documentation, which is not repeated here.
;; To install, merely put this file somewhere GNU Emacs will find it,
;; then add the following lines to your .emacs file:
;;
;; (autoload 'po-mode "po-mode"
;; "Major mode for translators to edit PO files" t)
;; (setq auto-mode-alist (cons '("\\.po\\'\\|\\.po\\." . po-mode)
;; auto-mode-alist))
;;
;; To use the right coding system automatically under Emacs 20 or newer,
;; also add:
;;
;; (autoload 'po-find-file-coding-system "po-compat")
;; (modify-coding-system-alist 'file "\\.po\\'\\|\\.po\\."
;; 'po-find-file-coding-system)
;;
;; You may also adjust some variables, below, by defining them in your
;; '.emacs' file, either directly or through command 'M-x customize'.
;;; Code:
(defconst po-mode-version-string "2.01" "\
Version number of this version of po-mode.el.")
;;; Emacs portability matters - part I.
;;; Here is the minimum for customization to work. See part II.
;; Identify which Emacs variety is being used.
;; This file supports:
;; - XEmacs (version 19 and above) -> po-XEMACS = t,
;; - GNU Emacs (version 20 and above) -> po-EMACS20 = t,
;; - GNU Emacs (version 19) -> no flag.
