The XML packaging used in the two cases is very +similar. The differences are the use of $uname and +$udom in stored internal messages, compared +with $email in stored +Domain Coordinator e-mail for the storage of information about +recipients of the message/e-mail. + +=head1 SUBROUTINES + +=over + +=pod + +=item packagemsg() + +Package + +=item get_course_context() + +=item unpackagemsg() + +Unpack message into a hash + +=item buildmsgid() + +Get info out of msgid + +=item unpackmsgid() + +=item sendemail() + +=item sendnotification() + +Send notification emails + +=item newmail() + +Check for email + +=item author_res_msg() + +Automated message to the author of a resource + +=item * B: Sends message $message to the owner + of the resource with the URI $filename. + +=item retrieve_author_res_msg() + +Retrieve author resource messages + +=item del_url_author_res_msg() + +Delete all author messages related to one URL + +=item clear_author_res_msg() + +Clear out all author messages in URL path + +=item all_url_author_res_msg() + +Return hash with URLs for which there is a resource message + +=item store_instructor_comment() + +Add a comment to the User Notes screen + +=item user_crit_msg_raw() + +Critical message to a user + +=item user_crit_msg() + +New routine that respects "forward" and calls old routine + +=item * B: + Sends a critical message $message to the $user at $domain.
