 	This file must be included by every front-end target driver that is
 	trying to register with the mid-level. This is the common portion
 	that gets included with all the low-level drivers.

 	To use this the low-level driver must define the variable my_template
 	of the type Scsi_Target_Template with all the needed functions and
 	values defined in scsi_target.h
