;; mgp-mode.el ;; --- A mode for editing MagicPoint files ;; ;; Tested on Mule 2.3, based on GNU Emacs 19.28 ;; Copyright (C) 1999 Hirotsugu Kakugawa ;; Maintainer: Hirotsugu Kakugawa (h.kakugawa@computer.org) ;; 1 Apr 1999 1.00 First Implementation ;; 2 Apr 1999 1.01 Added mgp-direc-emph. Changed key bindings. ;; 2 Apr 1999 1.10 Added jumping to error line in MagicPoint file ;; 4 Apr 1999 1.20 Added directive completion input feature ;; 5 Apr 1999 1.21 Added starting MagicPoint at the current page ;; 9 Apr 1999 1.22 Changed mistakes in software license. ;; 8 Dec 1999 1.30 Added syntax hilighting.
