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	offen‐
       sive  text,  or	spoilers  in  discussions about movies or books, or in
       other similar occasions.

RETURN VALUE
       strrot13 returns its argument.
