Re: Standardized file headers?

Suggestion: Something like

;;; -*- mode: lisp; package: maxima; syntax: common-lisp; base: 10 -*-
;;;
;;; This file has modifications to the original MIT code.
;;;
;;; Copyright (c) 1982

;;; This file is part of Maxima and is distributed under the terms

  1.
The claim "The data in this file contains enhancements" is unclear and vague.
  2.
My understand is that "all rights reserved" is outdated and a historical artifact.

Subject: [Maxima-discuss] Standardized file headers?

Caution: Non-NU Email


While working on breaking some circular dependencies, I need to create some new files. What is the appropriate header for these files. We seem to have a lot of styles, and of course, we have the old original version:


;;; -*-  Mode: Lisp; Package: Maxima; Syntax: Common-Lisp; Base: 10 -*- ;;;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;;     The data in this file contains enhancements.                   ;;;;;
;;;                                                                    ;;;;;
;;;  Copyright (c) 1984,1987 by William Schelter,University of Texas   ;;;;;
;;;     All rights reserved                                            ;;;;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;;     (c) Copyright 1982 Massachusetts Institute of Technology         ;;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;


The mode line is fine. But the rest is really rather outdated. I’m not proposing we change these in existing files, but we should have a standardized one for new files. There should probably be a copyright statement. I guess a mention of the copyright in COPYING would work?
