+;; demoisa.el Example Proof General instance for Isabelle
+;;
+;; Copyright (C) 1999 LFCS Edinburgh.
+;;
+;; Author: David Aspinall <David.Aspinall@ed.ac.uk>
+;;
+;; $Id$
+;;
+;; =================================================================
+;;
+;; See README in this directory for an introduction.
+;;
+;; NEW INSTANCES: please use demoisa-easy.el as a basis instead.
+;;
+;; Basic configuration is controlled by one line in `proof-site.el'.
+;; It has this line in proof-assistant-table:
+;;
+;;     (demoisa "Isabelle Demo"	"\\.ML$")
+;;
+;; From this it loads this file "demoisa/demoisa.el" whenever
+;; a .ML file is visited, and sets the mode to `demoisa-mode'
+;; (defined below).
+;;
+;; I've called this instance "Isabelle Demo Proof General" just to
+;; avoid confusion with the real "Isabelle Proof General" in case the
+;; demo gets loaded by accident.
+;;
+;; To make the line above take precedence over the real Isabelle mode
+;; later in the table, set PROOFGENERAL_ASSISTANTS=demoisa in the
+;; shell before starting Emacs  (or customize proof-assistants).
+;;

+;; ======== User settings for Isabelle ========
+;;
+;; Defining variables using customize is pretty easy.
+;; You should do it at least for your prover-specific user options.
+;;
+;; proof-site provides us with two customization groups
+;; automatically:  (based on the name of the assistant)
+;;
+;; 'isabelledemo        -  User options for Isabelle Demo Proof General
+;; 'isabelledemo-config -  Configuration of Isabelle Proof General
+;;			   (constants, but may be nice to tweak)
+;;
+;; The first group appears in the menu
+;;   ProofGeneral -> Customize -> Isabelledemo
+;; The second group appears in the menu:
+;;   ProofGeneral -> Internals -> Isabelledemo config
