NAME
       strrot13 - encrypt or decrypt string using rot13

SYNOPSIS
       #include <publib.h>
       char *strrot13(char *str);

DESCRIPTION
       strrot13  converts  the argument string using rot13, i.e., it replaces each letter a with n, n with a, b with o, o with b, and so on.  Con-
       verting twice results in the original string.  Non-letter characters are not converted.

       The rot13 encryption method is used commonly on USENET to hide offensive text, or spoilers in discussions about	movies	or  books,  or	in
       other similar occasions.

RETURN VALUE
       strrot13 returns its argument.
