    Description:    Part of the sample SCSIOldAndNew. This sample demonstrates how to use the SCSITask User

                    Client (STUC) and the (as of Mac OS X 10.2) deprecated IOSCSIUserClient APIs to find

                    SCSI devices and issue a simple INQUIRY command to each device.

    Change History (most recent first):

            1.1     10/10/2006          Updated to produce a universal binary. Now requires Xcode 2.2.1 or

                                        later to build.

            1.0     05/08/2003          New sample.
