define Package/tgt/description
-Linux SCSI target framework (tgt) aims to simplify various SCSI target driver (iSCSI, Fibre Channel, SRP, etc) creation and maintenance.
-Key goals of the project are the clean integration into the scsi-mid layer and implementing a great portion of tgt in user space.
-Tgt consists of kernel-space and user-space code. The kernel-space component is included in upstream as of 2.6.20.
-Note that if you are interested in only iSCSI (probably you are), you need only the user-space code (any kernel version is fine).
+The Linux target framework (tgt) is a user space SCSI target framework
+that supports the iSCSI and iSER transport protocols and that also
+supports multiple methods for accessing block storage. Tgt consists of
+a user-space daemon and user-space tools.
