                     37: Apache::lonmsg: supports internal messaging
                     38: 
                     39: =head1 SYNOPSIS
                     40: 
                     41: lonmsg provides routines for sending messages, receiving messages, and
                     42: a handler to allow users to read, send, and delete messages.
                     43: 
                     44: =head1 OVERVIEW
                     45: 
                     46: =head2 Messaging Overview
                     47: 
                     48: X<messages>LON-CAPA provides an internal messaging system similar to
                     49: email, but customized for LON-CAPA's usage. LON-CAPA implements its
                     50: own messaging system, rather then building on top of email, because of
                     51: the features LON-CAPA messages can offer that conventional e-mail can
                     52: not:
                     53: 
                     54: =over 4
                     55: 
                     56: =item * B<Critical messages>: A message the recipient B<must>
                     57: acknowlegde receipt of before they are allowed to continue using the
                     58: system, preventing a user from claiming they never got a message
                     59: 
                     60: =item * B<Receipts>: LON-CAPA can reliably send reciepts informing the
                     61: sender that it has been read; again, useful for preventing students
                     62: from claiming they did not see a message. (While conventional e-mail
                     63: has some reciept support, it's sporadic, e-mail client-specific, and
                     64: generally the receiver can opt to not send one, making it useless in
                     65: this case.)
                     66: 
                     67: =item * B<Context>: LON-CAPA knows about the sender, such as where
                     68: they are in a course. When a student mails an instructor asking for
                     69: help on the problem, the instructor receives not just the student's
                     70: question, but all submissions the student has made up to that point,
                     71: the user's rendering of the problem, and the complete view the student
                     72: saw of the resource, including discussion up to that point. Finally,
                     73: the instructor is reading all of this inside of LON-CAPA, not their
                     74: email program, so they have full access to LON-CAPA's grading
                     75: interface, or other features they may wish to use in response to the
                     76: student's query.
                     77: 
                     78: =item * B<Blocking>: LON-CAPA can block display of e-mails that are 
                     79: sent to a student during an online exam. A course coordinator or
                     80: instructor can set an open and close date/time for scheduled online
                     81: exams in a course. If a user uses the LON-CAPA internal messaging 
                     82: system to display e-mails during the scheduled blocking event,  
                     83: display of all e-mail sent during the blocking period will be 
                     84: suppressed, and a message of explanation, including details of the 
                     85: currently active blocking periods will be displayed instead. A user 
                     86: who has a course coordinator or instructor role in a course will be
                     87: unaffected by any blocking periods for the course, unless the user
                     88: also has a student role in the course, AND has selected the student role.
                     89: 
                     90: =back
                     91: 
                     92: Users can ask LON-CAPA to forward messages to conventional e-mail
                     93: addresses on their B<PREF> screen, but generally, LON-CAPA messages
                     94: are much more useful than traditional email can be made to be, even
                     95: with HTML support.
                     96: 
                     97: Right now, this document will cover just how to send a message, since
                     98: it is likely you will not need to programmatically read messages,
                     99: since lonmsg already implements that functionality.
                    100: 
                    101: The routines used to package messages and unpackage messages are not
                    102: only used by lonmsg when creating/extracting messages for LON-CAPA's
                    103: internal messaging system, but also by lonnotify.pm which is available
                    104: for use by Domain Coordinators to broadcast standard e-mail to specified
                    105: users in their domain.  The XML packaging used in the two cases is very
                    106: similar.  The differences are the use of <recuser>$uname</recuser> and 
                    107: <recdomain>$udom</recdomain> in stored internal messages, compared 
                    108: with <recipient username="$uname:$udom">$email</recipient> in stored
                    109: Domain Coordinator e-mail for the storage of information about 
                    110: recipients of the message/e-mail.
