 it is likely you will not need to programmatically read messages,
 since lonmsg already implements that functionality.
 
+The routines used to package messages and unpackage messages are not
+only used by lonmsg when creating/extracting messages for LON-CAPA's
+internal messaging system, but also by lonnotify.pm which is available
+for use by Domain Coordinators to broadcast standard e-mail to specified
+users in their domain.  The XML packaging used in the two cases is very
+similar.  The differences are the use of <recuser>$uname</recuser> and 
+<recdomain>$udom</recdomain> in stored internal messages, compared 
+with <recipient username="$uname:$udom">$email</recipient> in stored
+Domain Coordinator e-mail for the storage of information about 
+recipients of the message/e-mail.
