;;; Code:

;;; Directories (think `no-littering')

(defvar acdw/dir (expand-file-name
		  (convert-standard-filename "var/")
		  user-emacs-directory)
  "A directory to hold extra configuration and emacs data.")

(defun acdw/in-dir (file &optional make-directory)
  "Expand FILE relative to `acdw/dir', optionally creating its
directory."
  (let ((f (expand-file-name (convert-standard-filename file)
			     acdw/dir)))
    (when make-directory
      (make-directory (file-name-directory) 'parents))
    f))

;;; Settings

(defun acdw/set (assignments)
  "Perform `customize-set-variable' on each of ASSIGNMENTS.

ASSIGNMENTS is a list where each element is of the form
(VARIABLE VALUE [COMMENT])."
  (dolist (assn assignments)
    (customize-set-variable (car assignment)
			    (cadr assignment)
			    (if (and (caddr assignment)
				     (stringp (caddr assignment)))
				(caddr assignment)
			      "Customized by `acdw/set'."))))

;;; Keymap & Mode

  "A keymap for my custom bindings.")

(define-minor-mode acdw/mode
  "A mode for `acdw/map'."
  :init-value t
  :lighter " acdw"
  :keymap acdw/map)
(define-globalized-minor-mode acdw/global-mode acdw/mode acdw/mode)

;; Disable `acdw/mode' in the minibuffer
(defun acdw/mode--disable ()
