33: =head1 NAME
34:
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.
