21 * This script looks through all the module directories for cron.php files
22 * and runs them. These files can contain cleanup functions, email functions
23 * or anything that needs to be run on a regular basis.
25 * This file is best run from cron on the host system (ie outside PHP).
26 * It is strongly recommended to add password protection via admin settings.
28 * eg wget -q -O /dev/null 'http: *moodle.somewhere.edu/admin/cron.php?password=SeCreT666'
30 * It is also possible to use CLI script admin/cli/cron.php instead,
31 * you can not call this script from command line any more.
