DESCRIPTION = "Open-iSCSI project is a high performance, transport \
independent, multi-platform implementation of RFC3720. The iscsi package \
provides the server daemon for the iSCSI protocol, as well as the utility \
programs used to manage it. iSCSI is a protocol for distributed \
disk access using SCSI commands sent over Internet Protocol networks."
