|--------------------------------------------------------------
| CRON JOB BOOTSTRAPPER
|--------------------------------------------------------------
|
| This section is used to get a cron job going, using standard
| CodeIgniter controllers and functions.
|
| 1) Set the CRON_CI_INDEX constant to the location of your
|    CodeIgniter index.php file
| 2) Make this file executable (chmod a+x cron.php)
| 3) You can then use this file to call any controller function:
|    ./cron.php --run=/controller/method [--show-output] [--log-file=logfile] [--time-limit=N] 
|
| GOTCHA: Do not load any authentication or session libraries in
| controllers you want to run via cron. If you do, they probably
| won't run right.
