Log:
Module to build interface for management of automated enrollment by course coordinators. Can also be used to perform reconciliation of classlist with institutional data (via "update roster now" option - calls the same LONCAPA::Enrollment.pm module as the automated enrollment script). Requires addition of following to /etc/httpd/conf/loncapa_apache.conf -
