 * File: testargs.php

 * Purpose:
 * During installation we need to check if register_argc_argv is
 * enabled for the command line PHP processor, because otherwise
 * deliveries will fail. So we will do a shell exec of php and
 * execute this file with a command line argument, and see if it 
 * echoes the argument back to us. Otherwise notify the person 
 * that their installation doesn't meet the system requirements.
