These tools have a terminal UI and CLI for ZFS related operations. Specifically:

1. zpool-set manages ZFS pool properties (zpool get / zpool set), for FreeBSD
2. zfs-allow performs ZFS delegated administration (zfs allow / zfs unallow) on FreeBSD: every permission described, edits turned into the exact zfs commands, pre-flight checks, effective permissions, dump/restore.
3. zfs-set sets dataset properties (zfs get / zfs set / zfs inherit), for FreeBSD
