-;;   2. Position the cursor after expansion to a place specified by advance.
-;;   3. Indent the expanded region.
-;;   4. If a list of points as been provided with the abbreviation definition,
-;;   the functions expand-jump-to-previous-mark and expand-jump-to-next-mark

-;; Installation:
-;;   * store this file somewhere in your load-path and byte compile it.
-;;   * put (require 'expand) in your .emacs or in site-start.el or generate
-;; autoloads.
-;;   * and according to the mode install your expansion table.
