+
+=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.

+ (Additionally it also checks $env for whether the corresponding form.<name>
