;;; Commentary:
;; This file will be merged with "eev-steps.el" at some point,
;; hopefully soon... "eev-steps.el" is much more documented than this,
;; but the code there is a mess; here the names are better, and the
;; functions are much better factored than there.
;;
;; Note that "eev-all.el" loads "eev-mini-steps.el" after
;; "eev-steps.el", and so the definitions from this file will override
;; the definitions from "eev-steps.el" with the same names.
