19 * Web cron
20 *
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.
24 *
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.
27 *
28 * eg   wget -q -O /dev/null 'http: *moodle.somewhere.edu/admin/cron.php?password=SeCreT666'
29 *
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.
32 *
