       This module provides functions to convert string from / to Base32 encoding, specified in RACE internet-
       draft. The Base32 encoding is designed to encode non-ASCII characters in DNS-compatible host name parts.

       See http://tools.ietf.org/html/draft-ietf-idn-race-03 for more details.

       Following functions are provided; like "MIME::Base64", they are in @EXPORT array. See Exporter for
       details.

       encode_base32($str)
           Encode  data by calling the encode_base32() function. This function takes a string of bytes to encode
           and returns the encoded base32 string.

       decode_base32($str)
           Decode a base32 string by calling the decode_base32() function.  This  function  takes  a  string  to
           decode and returns the decoded string.

           This  function  might  throw the exceptions such as "Data contains non-base32 characters", "Length of
           data invalid" and "Padding bits at the end of output buffer are not all zero".

           decode_base32 differs from the specification in that upper case letters are treated  as  their  lower
           case equivalent rather than producing an error.
