* 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
2010-12-11 05:21:34 +01:00
* that their installation doesn't meet the system requirements.
