// and runs them. These files can contain cleanup functions, email functions
// or anything that needs to be run on a regular basis.
//
// This file is best run from cron on the host system (ie outside PHP).
// The script can either be invoked via the web server or via a standalone
// version of PHP compiled for CGI.

// eg wget -q -O /dev/null 'http://moodle.somewhere.edu/admin/cron.php'
// or php /web/moodle/admin/cron.php
