-*

-*  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.
