-=head1 NAME
-
-Apache::lonmsg: supports internal messaging
-
-=head1 SYNOPSIS
-
-lonmsg provides routines for sending messages, receiving messages, and
-a handler to allow users to read, send, and delete messages.
-
-=head1 OVERVIEW
-
-=head2 Messaging Overview
-
-X<messages>LON-CAPA provides an internal messaging system similar to
-email, but customized for LON-CAPA's usage. LON-CAPA implements its
-own messaging system, rather then building on top of email, because of
-the features LON-CAPA messages can offer that conventional e-mail can
-not:
-
-=over 4
-
-=item * B<Critical messages>: A message the recipient B<must>
-acknowlegde receipt of before they are allowed to continue using the
-system, preventing a user from claiming they never got a message
-
-=item * B<Receipts>: LON-CAPA can reliably send reciepts informing the
-sender that it has been read; again, useful for preventing students
-from claiming they did not see a message. (While conventional e-mail
-has some reciept support, it's sporadic, e-mail client-specific, and
-generally the receiver can opt to not send one, making it useless in
-this case.)
-
-=item * B<Context>: LON-CAPA knows about the sender, such as where
-they are in a course. When a student mails an instructor asking for
-help on the problem, the instructor receives not just the student's
-question, but all submissions the student has made up to that point,
-the user's rendering of the problem, and the complete view the student
-saw of the resource, including discussion up to that point. Finally,
-the instructor is reading all of this inside of LON-CAPA, not their
-email program, so they have full access to LON-CAPA's grading
-interface, or other features they may wish to use in response to the
-student's query.
-
-=item * B<Blocking>: LON-CAPA can block display of e-mails that are
-sent to a student during an online exam. A course coordinator or
-instructor can set an open and close date/time for scheduled online
-exams in a course. If a user uses the LON-CAPA internal messaging
-system to display e-mails during the scheduled blocking event,
-display of all e-mail sent during the blocking period will be
-suppressed, and a message of explanation, including details of the
-currently active blocking periods will be displayed instead. A user
-who has a course coordinator or instructor role in a course will be
-unaffected by any blocking periods for the course, unless the user
-also has a student role in the course, AND has selected the student role.
-
-=back
-
-Users can ask LON-CAPA to forward messages to conventional e-mail
-addresses on their B<PREF> screen, but generally, LON-CAPA messages
-are much more useful than traditional email can be made to be, even
-with HTML support.
-
-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.
