  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.
