2. Add the cron cartridge to your application by running the following command:

   $ rhc cartridge-add cron --app myapp
   

3. SSH into the application gear and download the s3-bash utility in $OPENSHIFT_DATA_DIR. Extract it to the s3-bash directory using the following commands:

   $ rhc ssh --app myapp
