   =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.
   
   =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 then 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.
