;;; Code:

;;; These are for handling :version.  We need to have a minimum of
;;; information so `custom-changed-variables' could do its job.  
;;; For both groups and variables we have to set `custom-version'.
;;; For variables we also set the `standard-value' and for groups
;;; `group-documentation' (which is shown in the customize buffer), so
;;; we don't have to load the file containing the group.

;;; `custom-versions-load-alist' is an alist that has as car a version
;;; number and as elts the files that have variables that contain that
;;; version. These files should be loaded before showing the
;;; customization buffer that `customize-changed-options' generates.


;;; This macro is used so we don't modify the information about
;;; variables and groups if it's already set. (We don't know when
;;; cus-load.el is going to be loaded and at that time some of the
;;; files might be loaded and some others might not).
