;; Commentary:
;;
;; * Installing
;;
;; To install, you just need to load it, an option is:
;;
;; (load-library "~/.emacs-dir/license.el")
;;
;; I recommend the following setup:
;;
;; (setq comment-style 'extra-line)
;; (add-hook 'scheme-mode-hook
;; (lambda ()
;; (set (make-local-variable 'comment-add) 1)))
;;
;; * Using
;;
;; If you run license like this:
;;
;; M-x license
;;
;; It will insert the license described in the
;; 'license-default'variable, the default value is GPL. If you would
;; like to use another license try:
;;
;; C-u M-x license
;;
;; It will prompt you for the license you want to use, you may see the
;; available options by hitting tab.
;;
;; If you would like to modify the default license, try:
;;
;; (setq license-default "license")
;; Code:
