Reading Rot13 Messages
======================
Mailing list messages that might offend some readers are sometimes
encoded in a simple code called "rot13"--so named because it rotates
the alphabet by 13 letters. This code is not for secrecy, as it
provides none; rather, it enables those who might be offended to avoid
ever seeing the real text of the message.
To view a buffer using the rot13 code, use the command `M-x
rot13-other-window'. This displays the current buffer in another window
which applies the code when displaying the text.
