<DL>
<DD>Setup this Multipart object from the given MultipartDataSource. <p>

 The method adds the MultipartDataSource's BodyPart 
 objects into this Multipart. This Multipart's contentType is
 set to that of the MultipartDataSource. <p>

 This method is typically used in those cases where one 
 has a multipart data source that has already been pre-parsed into
 the individual body parts (for example, an IMAP datasource), but 
 needs to create an appropriate Multipart subclass that represents
 a specific multipart subtype.
