### Create a new multipart message:
$msg = MIME::Lite->new
    (
        From    => 'me@myhost.com',
        To      => 'you@yourhost.com',
        Cc      => 'some@other.com, some@more.com',
        Subject => 'A message with 2 parts...',
        Type    => 'multipart/mixed'
    );

### use Net:SMTP to do the sending
    $msg->send('smtp','some.host', Debug=>1 );
    
    Same as:
    $msg->send('smtp'  => 'some.host',
               'Debug' => 1
              );
