 ;; Commentary:
 
+;; The single entry point, `rot13-other-window', oerforms a Caesar cipher
+;; encrypt/decrypt on the current buffer and displays the result in another 
+;; window.  Rot13 encryption is sometimes used on USENET as a read-at-yur-
+;; own-risk wrapper for material some might consider offensive, such as
+;; ethnic humor.
