        based_on => BODY
        boundary => STRING
          Separator to be used between parts of the message. This separator must be unique in case
          the message contains nested multiparts (which are not unusual). If "undef", a nice unique
          boundary will be generated.

        charset => CHARSET|'PERL'|<undef>
        checked => BOOLEAN
        content_id => STRING
        data => ARRAY-OF-LINES | STRING
        description => STRING|FIELD
        disposition => STRING|FIELD
        eol => 'CR'|'LF'|'CRLF'|'NATIVE'
        epilogue => BODY|STRING
          The text which is included in the main body after the final boundary. This is usually
          empty, and has no meaning.

          Provide a BODY object or a STRING which will automatically translated into a "text/plain"
          body.

        file => FILENAME|FILEHANDLE|IOHANDLE
        filename => FILENAME
        log => LEVEL
        message => MESSAGE
        mime_type => STRING|FIELD|MIME
        modified => BOOLEAN
        parts => ARRAY-OF-(MESSAGES|BODIES)
          Specifies an initial list of parts in this body. These may be full MESSAGES, or BODIES
          which transformed into messages before use. Each message is coerced into a
          [Mail::Message::Part](https://www.chedong.com/phpMan.php/perldoc/Mail%3A%3AMessage%3A%3APart/markdown) object.

          [MIME::Entity](https://www.chedong.com/phpMan.php/perldoc/MIME%3A%3AEntity/markdown) and [Mail::Internet](https://www.chedong.com/phpMan.php/perldoc/Mail%3A%3AInternet/markdown) objects are acceptable in the list, because they are
          coercible into [Mail::Message::Part](https://www.chedong.com/phpMan.php/perldoc/Mail%3A%3AMessage%3A%3APart/markdown)'s. Values of "undef" will be skipped silently.

        preamble => BODY|STRING
          The text which is included in the body before the first part. It is common use to include
          a text to warn the user that the message is a multipart. However, this was useful in
          earlier days: most mail agents are very capable in warning the user themselves.

          Provide a BODY object or a STRING which will automatically translated into a text/plain
          body.

        trace => LEVEL
        transfer_encoding => STRING|FIELD

        example:

         my $intro = [Mail::Message::Body](https://www.chedong.com/phpMan.php/perldoc/Mail%3A%3AMessage%3A%3ABody/markdown)->new(data => ['part one']);
         my $pgp   = [Mail::Message::Body](https://www.chedong.com/phpMan.php/perldoc/Mail%3A%3AMessage%3A%3ABody/markdown)->new(data => ['part three']);

         my $body  = [Mail::Message::Body::Multipart](https://www.chedong.com/phpMan.php/perldoc/Mail%3A%3AMessage%3A%3ABody%3A%3AMultipart/markdown)->new
           ( boundary => time . '--it-s-mine'
           , preamble => "This is a multi-part message in MIME format.\n\n"
           , parts    => [ $intro, $folder->[message(3)](https://www.chedong.com/phpMan.php/man/message/3/markdown)->decoded, $pgp ]
           );

    $obj->attach($messages|$bodies)
        Attach a list of $messages to this multipart. A new body is returned. When you specify
        $bodies, they will first be translated into real messages. [MIME::Entity](https://www.chedong.com/phpMan.php/perldoc/MIME%3A%3AEntity/markdown) and [Mail::Internet](https://www.chedong.com/phpMan.php/perldoc/Mail%3A%3AInternet/markdown)
        objects may be specified too. In any case, the parts will be coerced into
        [Mail::Message::Part](https://www.chedong.com/phpMan.php/perldoc/Mail%3A%3AMessage%3A%3APart/markdown)'s.

    $obj->foreachComponent(CODE)
        Execute the CODE for each component of the message: the preamble, the epilogue, and each of
        the parts.

        Each component is a body and is passed as second argument to the CODE. The first argument is
        a reference to this multi-parted body. The CODE returns a body object. When any of the
        returned bodies differs from the body which was passed, then a new multi-part body will be
        returned. Reference to the not-changed bodies and the changed bodies will be included in
        that new multi-part.

        example:

         my $checked = $multi->foreachComponent(sub {$_[1]->check});

    $obj->foreachLine((CODE))
        It is NOT possible to call some code for each line of a multipart, because that would not
        only inflict damage to the body of each message part, but also to the headers and the part
        separators.

    $obj->stripSignature(%options)
        Removes all parts which contains data usually defined as being signature. The [MIME::Type](https://www.chedong.com/phpMan.php/perldoc/MIME%3A%3AType/markdown)
        module provides this knowledge. A new multipart is returned, containing the remaining parts.
        No %options are defined yet, although some may be specified, because this method overrules
        the "stripSignature" method for normal bodies.

### Access to the payload
    Extends "Access to the payload" in [Mail::Message::Body](https://www.chedong.com/phpMan.php/perldoc/Mail%3A%3AMessage%3A%3ABody/markdown).

    $obj->boundary( [STRING] )
        Returns the boundary which is used to separate the parts in this body. If none was read from
        file, then one will be assigned. With STRING you explicitly set the boundary to be used.

    $obj->endsOnNewline()
        Inherited, see "Access to the payload" in [Mail::Message::Body](https://www.chedong.com/phpMan.php/perldoc/Mail%3A%3AMessage%3A%3ABody/markdown)

    $obj->epilogue()
        Returns the epilogue; the text after the last message part (after the last real attachment).
        The epilogue is stored in a BODY object, and its encoding is taken from the general
        multipart header.

    $obj->file()

    $obj->part($index)
        Returns only the part with the specified $index. You may use a negative value here, which
        counts from the back in the list. Parts which are flagged to be deleted are included in the
        count.

        example:

         $message->body->[part(2)](https://www.chedong.com/phpMan.php/man/part/2/markdown)->print;
         $body->[part(1)](https://www.chedong.com/phpMan.php/man/part/1/markdown)->delete;

    $obj->parts( [<'ALL'|'ACTIVE'|'DELETED'|'RECURSE'|$filter>] )
        Return all parts by default, or when ALL is specified. "ACTIVE" returns the parts which are
        not flagged for deletion, as opposite to "DELETED". "RECURSE" descents into all nested
        multiparts to collect all parts.

        You may also specify a code reference which is called for each nested part. The first
        argument will be the message part. When the code returns true, the part is incorporated in
        the return list.

        example:

         print "Number of attachments: ",
             scalar $message->body->parts('ACTIVE');

         foreach my $part ($message->body->parts) {
             print "Type: ", $part->get('Content-Type');
         }

    $obj->preamble()
        Returns the preamble; the text before the first message part (before the first real
        attachment). The preamble is stored in a BODY object, and its encoding is taken from the
        multipart header.

## DIAGNOSTICS
    Warning: Charset $name is not known
        The encoding or decoding of a message body encounters a character set which is not
        understood by Perl's Encode module.

    Error: Data not convertible to a message (type is $type)
        An object which is not coercable into a [Mail::Message::Part](https://www.chedong.com/phpMan.php/perldoc/Mail%3A%3AMessage%3A%3APart/markdown) object was passed to the
        initiation. The data is ignored.

    Warning: No decoder defined for transfer encoding $name.
        The data (message body) is encoded in a way which is not currently understood, therefore no
        decoding (or recoding) can take place.

    Warning: No encoder defined for transfer encoding $name.
        The data (message body) has been decoded, but the required encoding is unknown. The decoded
        data is returned.

    Error: Package $package does not implement $method.
        Fatal error: the specific package (or one of its superclasses) does not implement this
        method where it should. This message means that some other related classes do implement this
        method however the class at hand does not. Probably you should investigate this and probably
        inform the author of the package.

    Error: Unknown criterium $what to select parts.
        Valid choices fdr part selections are "ALL", "ACTIVE", "DELETED", "RECURSE" or a code
        reference. However, some other argument was passed.

    Warning: Unknown line terminator $eol ignored
    Error: You cannot use foreachLine on a multipart
        foreachLine() should be used on decoded message bodies only, because it would attempt to
        modify part-headers and separators as well, which is clearly not acceptable.
