+ 
+ ;;; Commentary:
+ 
+ ;; This package deals with the primitive form of underlining
+ ;; consisting of prefixing each character with "_\^h".  The entry
+ ;; point `underline-region' performs such underlining on a region.
+ ;; The entry point `ununderline-region' removes it.
+ 
+ ;;; Code:
+ 
+ ;;;###autoload
+ (defun underline-region (start end)
+   "Underline all nonblank characters in the region.
+ Works by overstriking underscores.
+ Called from program, takes two arguments START and END
+ which specify the range to operate on."
+   (interactive "*r")
+   (save-excursion
+    (let ((end1 (make-marker)))
+      (move-marker end1 (max start end))
+      (goto-char (min start end))
+      (while (< (point) end1)
+        (or (looking-at "address@hidden ]")
+          (insert "_\b"))
