* RFC 822 Email address list validation Utility
*
* What is it?
*
* This class will take an address string, and parse it into it's consituent
* parts, be that either addresses, groups, or combinations. Nested groups
* are not supported. The structure it returns is pretty straight forward,
* and is similar to that provided by the imap_rfc822_parse_adrlist(). Use
* print_r() to view the structure.
*
* How do I use it?
*
* $address_string = 'My Group: "Richard Heyes" <richard@localhost> (A comment), ted@example.com (Ted Bloggs), Barney;';
* $structure = Mail_RFC822::parseAddressList($address_string, 'example.com', TRUE)

/**
*
* 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.
