define Package/scst/description
 A generic SCSI target subsystem for Linux that allows to convert any Linux
 server into a sophisticated storage server. The three layers in SCST are the
 target driver layer; the SCSI target core and the device handler layer. SCST
 target drivers realize communication with an initiator and implement a storage
 protocol like iSCSI, FC or SRP. SCST device handlers implement a SCSI
 interface on top of local storage.
