* This class is based on HTML Mime Mail class from
* Richard Heyes <richard@phpguru.org> which was based also
* in the mime_mail.class by Tobias Ratschiller <tobias@dnet.it>
* and Sascha Schumann <sascha@schumann.cx>
* This package depends on PEAR to raise errors.
* Mail_mimePart contains the code required to
* create all the different parts a mail can
require_once 'Mail/mimePart.php';
* The Mail_Mime class provides an OO interface to create MIME
* enabled email messages. This way you can create emails that
* contain plain-text bodies, HTML bodies, attachments, inline
* images and specific headers.
