           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.

           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

           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 $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.

           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.
