## <summary>Linux Target Framework Daemon.</summary>
## <desc>
##      <p>
##	Linux target framework (tgt) aims to simplify various 
##	SCSI target driver (iSCSI, Fibre Channel, SRP, etc) creation 
##	and maintenance. Our key goals are the clean integration into 
##	the scsi-mid layer and implementing a great portion of tgt 
##	in user space.
