                     51: Apache::lonmsg: supports internal messaging
                     52: 
                     53: =head1 SYNOPSIS
                     54: 
                     55: lonmsg provides routines for sending messages, receiving messages, and
                     56: a handler to allow users to read, send, and delete messages.
                     57: 
                     58: =head1 OVERVIEW
                     59: 
                     60: =head2 Messaging Overview
                     61: 
                     62: X<messages>LON-CAPA provides an internal messaging system similar to
                     63: email, but customized for LON-CAPA's usage. LON-CAPA implements its
                     64: own messaging system, rather then building on top of email, because of
                     65: the features LON-CAPA messages can offer that conventional e-mail can
                     66: not:
                     67: 
                     68: =over 4
                     69: 
                     70: =item * B<Critical messages>: A message the recipient B<must>
                     71: acknowlegde receipt of before they are allowed to continue using the
                     72: system, preventing a user from claiming they never got a message
                     73: 
                     74: =item * B<Receipts>: LON-CAPA can reliably send reciepts informing the
                     75: sender that it has been read; again, useful for preventing students
                     76: from claiming they did not see a message. (While conventional e-mail
                     77: has some reciept support, it's sporadic, e-mail client-specific, and
                     78: generally the receiver can opt to not send one, making it useless in
                     79: this case.)
                     80: 
                     81: =item * B<Context>: LON-CAPA knows about the sender, such as where
                     82: they are in a course. When a student mails an instructor asking for
                     83: help on the problem, the instructor receives not just the student's
                     84: question, but all submissions the student has made up to that point,
                     85: the user's rendering of the problem, and the complete view the student
                     86: saw of the resource, including discussion up to that point. Finally,
                     87: the instructor is reading all of this inside of LON-CAPA, not their
                     88: email program, so they have full access to LON-CAPA's grading
                     89: interface, or other features they may wish to use in response to the
                     90: student's query.
                     91: 
                     92: =back
                     93: 
                     94: Users can ask LON-CAPA to forward messages to conventional e-mail
                     95: addresses on their B<PREF> screen, but generally, LON-CAPA messages
                     96: are much more useful then traditional email can be made to be, even
                     97: with HTML support.
                     98: 
                     99: Right now, this document will cover just how to send a message, since
                    100: it is likely you will not need to programmatically read messages,
                    101: since lonmsg already implements that functionality.
