;;; about copying nibfiles

;;; when building an app bundle, we copy nibfiles from the development
;;; environment appplication bundle into the newly-created application
;;; bundle. If user-supplied nibfiles are given the same names as
;;; nibfiles from the development environment, we signal an error and
;;; refuse to copy the user nibfiles. This treatment ensures that users
;;; will not accidentally clobber dev-environment nibfiles, but also
;;; means that they must give unique names to their own nibs in order
;;; to use them with their saved applications.

;;; in future, we may add options to suppress the copying of
;;; dev-environment nibfiles.
