;;; Commentary:

;; This packages aims at providing a convenient way of creating license
;; files.  The core command is `create-license', which you can invoke
;; interactively using M-x.

;; The licenses are stored in the directory `create-license-directory'.

;;; Code:

(defgroup create-license nil
  "Conveniently create license files."
  :group 'emacs
  :prefix "create-license-")

(defcustom create-license-file-name "COPYING"
  "The name of the license file."
  :group 'create-license
  :type 'string
  :safe 'stringp)

(defcustom create-license-directory
  (file-name-as-directory (expand-file-name "licenses" user-emacs-directory))
  "Directory where licenses are stored.

`create-license' ignores files in this directory whose name start by a
dot."
  :group 'create-license
  :type 'string)

;;;###autoload
(defun create-license (dir name)
  "Copy the license NAME in DIR.

The destination file name under DIR is given by
`create-license-file-name'."
  (interactive (list
		default-directory
		(completing-read
		 "License: "
		 (directory-files create-license-directory nil "^[^\\.].*"))))
  (copy-file (expand-file-name name create-license-directory)
	     (expand-file-name create-license-file-name dir)))

(provide 'create-license)
