+;;; Commentary:
+
+;; Having loaded this code you can set the region by holding down the
+;; shift key and move the cursor to the other end of the region.  The
+;; functionality provided by this code is similar to that provided by
+;; the editors of Borland International's compilers for ms-dos.
+
+;; Currently, s-region-move may be bound only to events that are vectors
+;; of length one and whose last element is a symbol.  Also, the functions
+;; that are given this kind of overlay should be (interactive "p")
+;; functions.
+
+;; If the following keys are not already bound then...
+;; C-insert is bound to copy-region-as-kill
+;; S-delete is bound to kill-region
+;; S-insert is bound to yank
+
