+ * 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.
