      To: recipient@example.com
      From: sender@example.com
      Subject: Hello there folks

      __MESSAGE__

      # more complex
      my $bulk = Email::Send->new;

          $bulk->mailer($_) and last if $bulk->mailer_available($_);
      }

      $bulk->message_modifier(sub {

          $message->header_set(To => qq[$to\@geeknest.com])
      });

      my $rv = $bulk->send($message, $_) for @to;

DESCRIPTION
    This module provides a very simple, very clean, very specific interface
    to multiple Email mailers. The goal if this software is to be small and
    simple, easy to use, and easy to extend.

  Constructors
    new()
          my $mailer = Email::Send->new({
              mailer      => 'NNTP',
              mailer_args => [ Host => 'nntp.example.com' ],
          });

        Create a new mailer object. This method can take parameters for any
        of the data properties of this module. Those data properties, which
        have their own accessors, are listed under "Properties".

  Properties
    mailer
        The mailing system you'd like to use for sending messages with this
        object. This is not defined by default. If you don't specify a
        mailer, all available plugins will be tried when the "send()" method
        is called until one succeeds.

    mailer_args
        Arguments passed into the mailing system you're using.

    message_modifier
        If defined, this callback is invoked every time the "send()" method
        is called on an object. The mailer object will be passed as the
        first argument. Second, the actual "Email::Simple" object for a
        message will be passed. Finally, any additional arguments passed to
        "send()" will be passed to this method in the order they were
        recieved.

        This is useful if you are sending in bulk.

  Methods
    send()
          my $result = $mailer->send($message, @modifier_args);

        Send a message using the predetermined mailer and mailer arguments.
        If you have defined a "message_modifier" it will be called prior to
        sending.

        The first argument you pass to send is an email message. It must be
        in some format that "Email::Abstract" can understand. If you don't
        have "Email::Abstract" installed then sending as plain text or an
        "Email::Simple" object will do.

        Any remaining arguments will be passed directly into your defined
        "message_modifier".

    all_mailers()
          my @available = $mailer->all_mailers;

        Returns a list of availabe mailers. These are mailers that are
        installed on your computer and register themselves as available.

    mailer_available()
          # is SMTP over SSL avaialble?
          $mailer->mailer('SMTP')
            if $mailer->mailer_available('SMTP', ssl => 1);

        Given the name of a mailer, such as "SMTP", determine if it is
        available. Any additional arguments passed to this method are passed
        directly to the "is_available()" method of the mailer being queried.

  Writing Mailers
      package Email::Send::Example;

      use UNIVERSAL::require;

      sub is_available {
          Net::Example->require;
      }

      sub send {
          my ($class, $message, @args) = @_;
          Net::Example->require;
          Net::Example->do_it($message) or return;
      }
  
      1;

    Writing new mailers is very simple. If you want to use a short name when
    calling "send", name your mailer under the "Email::Send" namespace. If
    you don't, the full name will have to be used. A mailer only needs to
    implement a single function, "send". It will be called from
    "Email::Send" exactly like this.

      Your::Sending::Package::send($message, @args);

    $message is an Email::Simple object, @args are the extra arguments
    passed into "Email::Send::send".

    Here's an example of a mailer that sends email to a URL.

      package Email::Send::HTTP::Post;
      use strict;

      use vars qw[$AGENT $URL $FIELD];
      use UNIVERSAL::require;
      use Return::Value;
  
      sub is_available {
              LWP::UserAgent->require;
      }

      sub send {
          my ($message, @args);

              LWP::UserAgent->require;

          if ( @args ) {
              my ($URL, $FIELD) = @args;
              $AGENT = LWP::UserAgent->new;
          }
          return failure "Can't send to URL if no URL and field are named"
            unless $URL && $FIELD;
          $AGENT->post($URL => { $FIELD => $message->as_string });
              return success;
      }

      1;

    This example will keep a UserAgent singleton unless new arguments are
    passed to "send". It is used by calling "Email::Send::send".

      my $mailer = Email::Send->new({ mailer => 'HTTP::Post' });
  
      $mailer->mailer_args([ 'http://example.com/incoming', 'message' ]);

      $mailer->send($message);
      $mailer->send($message2); # uses saved $URL and $FIELD
