                     35: Apache::lonmsg: supports internal messaging
                     36: 
                     37: =head1 SYNOPSIS
                     38: 
                     39: lonmsg provides routines for sending messages.
                     40: 
                     41: Right now, this document will cover just how to send a message, since
                     42: it is likely you will not need to programmatically read messages,
                     43: since lonmsg already implements that functionality.
                     44: 
                     45: The routines used to package messages and unpackage messages are not
                     46: only used by lonmsg when creating/extracting messages for LON-CAPA's
                     47: internal messaging system, but also by lonnotify.pm which is available
                     48: for use by Domain Coordinators to broadcast standard e-mail to specified
                     49: users in their domain.  The XML packaging used in the two cases is very
                     50: similar.  The differences are the use of <recuser>$uname</recuser> and
                     51: <recdomain>$udom</recdomain> in stored internal messages, compared
                     52: with <recipient username="$uname:$udom">$email</recipient> in stored
                     53: Domain Coordinator e-mail for the storage of information about
                     54: recipients of the message/e-mail.
