* print_r($structure);
*
* Or statically:

*
* TODO:

> And I have inserted the following line to the class:

> if (strtolower($charset)=="utf-8") $text=decode_utf8($text);
>
> ... before the following one in the "_decodeHeader" function:

> $input = str_replace($encoded, $text, $input);
>
> This way from now on it can easily decode the UTF-8 headers too.

* Raw mime encoding class
*
* What is it?
* This class enables you to manipulate and build
* a mime email from the ground up.
*
* Why use this instead of mime.php?
* mime.php is a userfriendly api to this class for
* people who aren't interested in the internals of
* mime mail. This class however allows full control
* over the email.
*
* Eg.
*
* // Since multipart/mixed has no real body, (the body is
* // the subpart), we set the body argument to blank.
*
* $params['content_type'] = 'multipart/mixed';
* $email = new Mail_mimePart('', $params);
*
* // Here we add a text part to the multipart we have
* // already. Assume $body contains plain text.
*
* $params['content_type'] = 'text/plain';
* $params['encoding'] = '7bit';
* $text = $email->addSubPart($body, $params);
*
* // Now add an attachment. Assume $attach is
* the contents of the attachment
*
* $params['content_type'] = 'application/zip';
* $params['encoding'] = 'base64';
* $params['disposition'] = 'attachment';
* $params['dfilename'] = 'example.zip';
* $attach =& $email->addSubPart($body, $params);
*
* // Now build the email. Note that the encode
* // function returns an associative array containing two
* // elements, body and headers. You will need to add extra
* // headers, (eg. Mime-Version) before sending.
*
* $email = $message->encode();
* $email['headers'][] = 'Mime-Version: 1.0';
*
*
* Further examples are available at http://www.phpguru.org
*
* TODO:
* - Set encode() to return the $obj->encoded if encode()
* has already been run. Unless a flag is passed to specifically
* re-build the message.
