  18   * Web cron
  19   *
  20   * This script looks through all the module directories for cron.php files
  21   * and runs them.  These files can contain cleanup functions, email functions
  22   * or anything that needs to be run on a regular basis.
  23   *
  24   * This file is best run from cron on the host system (ie outside PHP).
  25   * It is strongly recommended to add password protection via admin settings.
  26   *
  27   * eg   wget -q -O /dev/null 'http: *moodle.somewhere.edu/admin/cron.php?password=SeCreT666'
  28   *
  29   * It is also possible to use CLI script admin/cli/cron.php instead,
  30   * you can not call this script from command line any more.
  31   *
