;; logtalk.el -- font lock support for Logtalk (http://logtalk.org/) ;; Copyright (C) 2003-2006 Paulo Moura ;; Author: Paulo Moura ;; Creation date: November 15, 2003 ;; Last modification date: October 16, 2006 ;; Version: 0.91 ;; Installation: ;; ;; First, copy this file to the appropriated directory. For FSF Emacs this will ;; probably be /usr/local/share/emacs/site-lisp. For XEmacs, the directory is ;; usully /usr/local/lib/xemacs/site-lisp. You may also copy the file to a ;; sub-directory in your home directory depending on your Emacs configuration. ;; Type "C-h v load-path" in Emacs to find the list of paths that are searched ;; for when looking for lisp files. ;; ;; Second, add the following lines in your Emacs init file, for example ;; your ~/.emacs file: ;; ;; (autoload 'logtalk-mode "logtalk" "Major mode for editing Logtalk programs." t) ;; (setq auto-mode-alist (cons '("\\.lgt\\'" . logtalk-mode) auto-mode-alist)) ;;
