   =head1 NAME
   
   Apache::lonmsg: supports internal messaging
   
   =head1 SYNOPSIS
   
   lonmsg provides routines for sending messages.
   
   Right now, this document will cover just how to send a message, since
   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.
