Whenever we create a new source code file for a free software with Emacs we need first to add the short brief of the blessed GNU GPL v3. You can add a LISP function to your “~/.emacs” configuration file and call it whenever you want to add it.

If the file is missing you can create it.

After inserting the function and restarting Emacs you can call the function:

M-x insert-short-gpl (press Alt-x, type insert-short-gpl, press return).

Insert the following code to your “~/.emacs” file:

;; define function for inserting the short brief of GNU GPL v3.
(defun insert-short-gpl ()
 "Insert the short brief of GNU GPL v3."
