           print Sisimai::RFC2045->parameter($r, 'boundary'); # Apple-Mail-1-526612466
           print Sisimai::RFC2045->parameter($r);             # multipart/mixed

   "boundary(String, Integer)"
       boundary() returns a boundary string from the value of Content-Type header.

           my $r = 'Content-Type: multipart/mixed; boundary=Apple-Mail-1-526612466';
           my $v = Sisimai::RFC2045->boundary($r);
           print $v;   # Apple-Mail-1-526612466

           print Sisimai::RFC2045->boundary($r, 0); # --Apple-Mail-1-526612466

           print Sisimai::RFC2045->boundary($r, 1); # --Apple-Mail-1-526612466--
