Extend DNSEval.pm?

[William Taylor]

Is there anyway to extend this in DNSEval.pm locally without patching? Maybe 
with a plugin or something?

  my @originating = ();
  for my $header ('X-Originating-IP', 'X-Apparently-From') {
    my $str = $pms->get($header);
    next unless $str;
    push (@originating, ($str =~ m/($IP_ADDRESS)/g));
  }

I want to add a few headers here but I didn't want to have to patch on each 
upgrade.

Thanks,
 William
