<para>
This function performs the ROT13 encoding on the
<parameter>str</parameter> argument and returns the resulting
string. The ROT13 encoding simply shifts every letter by 13
places in the alphabet while leaving non-alpha characters
untouched. Encoding and decoding are done by the same function,
passing an encoded string as argument will return the original version.
