 - When on Cheyenne, set use_cron_to_relaunch=false
 - When use_cron_to_relaunch=false, output a message at the end of the script
   describing how to run the new run_srw_tests.py script to manage the tests
 - Regardless of other variables, print a message at the end of the script
   showing the user where the test directory is
