   =head1 NAME
   
   Apache::lonmsg: supports internal messaging
   
   =head1 SYNOPSIS
   
   lonmsg provides routines for sending messages.
   
   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.
   
   The routines used to package messages and unpackage messages are not
   only used by lonmsg when creating/extracting messages for LON-CAPA's
   internal messaging system, but also by lonnotify.pm which is available
   for use by Domain Coordinators to broadcast standard e-mail to specified
   users in their domain.  The XML packaging used in the two cases is very
   similar.  The differences are the use of <recuser>$uname</recuser> and
   <recdomain>$udom</recdomain> in stored internal messages, compared
   with <recipient username="$uname:$udom">$email</recipient> in stored
   Domain Coordinator e-mail for the storage of information about
   recipients of the message/e-mail.

   Arguments
     $feedurl - /res/ url of resource (only need if $author is true)
     $author,$question,$course,$policy - all true/false parameters
       if true will attempt to find the addresses of user that should receive
       this type of feedback (author - feedback to author of resource $feedurl,
       $question 'Resource Content Questions', $course 'Course Content Question',
       $policy 'Course Policy')
       (Additionally it also checks $env for whether the corresponding form.<name>
       element exists, for ease of use in a html response context)
      
     $defaultflag - (internal should be left blank) if true gather addresses 
                    that aren't for a section even if I have a section
                    (used for reccursion internally, first we look for
                    addresses for our specific section then we recurse
                    and look for non section addresses)
   
   Returns
     $typestyle - string of html text, describing what addresses were found
     %to - a hash, which keys are addresses of users to send messages to
           the keys will look like   name:domain
