;; This file manages the location of the custom init file without

;;; Code:
(provide 'cus-file)
;;;###autoload
(defconst custom-file-base "custom.el"
"Base of file name for storing customization information.")
;;;###autoload
(defvar custom-file nil
"File used for storing customization information.
If you change this from the default you need to
explicitly load that file for the settings to take effect.")
;;;###autoload
(defun make-custom-file-name (init-file &optional force-new)
"Construct the default custom file name from the init file name.
If FORCE-NEW is non-nil, force post-migration location."
