-
-=head1	DESCRIPTION
-
-=head2	fml4 と fml5 の相違点
-
-fml5 の最大の目的の一つは、メンバーリストの取得と操作の統合と抽象化で
-す。Netlib::SMTP は次のように使います。
-
-
-=head1	使い方
-
-=head2 Netlib::* クラスの使い方について
-
-Netlib::* に属するクラスは SMTP および LMTP 配送へのインターフェイスを
-提供します。
-
-Netlib::SMTP は次のように使います。
-
-    use Netlib::SMTP;
-    my $service = new Netlib::SMTP {
-	log_function   => $fp,
-	socket_timeout => 2,
-    };
-
-    my $ref_to_array   = [ 'kenken@nuinui.net' ];
-    my $recipient_maps = 'file:/var/spool/ml/elena/actives';
-
-    $service->deliver(
-		      {
-			  'mta'             => 'localhost:25',
-
-			  'smtp_sender'     => 'rudo@nuinui.net',
-			  'recipient_array' => $ref_to_array,
-			  'recipient_maps'  => $recipient_maps,
-
-			  'header'          => $header,
-			  'body'            => $body,
-		      });
-    if ($service->error) { Log($service->error); return;}
-
-ここで $header はヘッダで、FML::Header オブジェクトです。
-そして $body   はメール本文で、FML::Body オブジェクトです。

-C<mta> is a list of MTA's.
-The syntax of each MTA is address:port style. 
-If you use a raw IPv6 address, use [address]:port syntax. 
-For example, [::1]:25 (v6 loopback).
-You can specify IPv4 and IPv6 addresses.
-deliver() automatically tries smtp in both protocols.
-
-C<smtp_sender> is the sender's email address. It is used at MAIL FROM:
-parameter.
-
-C<recipient_maps> is a list of C<maps>.
-See L<IO::MapAdapter> for more details. 
-For example,
-
-to read address from a file
-
-         file:/var/spool/ml/elena/recipients
-
-to read addresses from /etc/group
-
-         unix.group:fml
-
-C<recipient_limit> is the max number of recipients in one SMTP
-transaction. 1000 by default, which corresponds to the limit by Postfix. 
-
-C<header> is FML::Header object.
-
-C<body> is Netlib::Messages object.
