# Collection of routines used for batch creation of courses and users.
# &create_courses() should be called by an Autocreate.pl
# script via a cron entry, or alternatively from a web page, after upload
# of a file containing an XML description of a course request (lonbatchccrs.pm).
#
# XML file(s) describing courses that are to be created in domain $dom are stored in
# /home/httpd/perl/tmp/addcourse/$dom
#
# &create_courses() will create an account for the course owner
# (if one does not currently exist), will create the course (cloning if necessary),
# and will add additional instructional staff (creating accounts if necessary).
#
# Example of XML file (which could contain more than one class to be created):
#
