CONSTRUCTOR
       fetch() - retrieve a public key record from DNS

	 my $public_key = Mail::DKIM::PublicKey->fetch(
			     Protocol => "dns",
			     Selector => "brisbane",
			     Domain => "example.com",
			   );

       If the public key is found, a Mail::DKIM::PublicKey object is
       returned, representing the information found in DNS.  If the public
       key does not exist in DNS, then "undef" is returned.  If a DNS error
       occurs while fetching the key, then this method will "die".  If the
       public key was found, but is not valid (e.g. it is "revoked"), then
       this method will "die".

METHODS
       granularity() - get or set the granularity (g=) field

	 my $g = $public_key->granularity;

	 $public_key->granularity("*");

       Granularity of the key. The value must match the Local-part of the
       effective "i=" tag of the DKIM-Signature header field.  The granular-
       ity is a literal value, or a pattern with a single ’*’ wildcard char-
       acter that matches zero or more characters.

       If no granularity is defined, then the default value, ’*’, will be
       returned.
