Description
-----------

The utility checks zone file syntax and runs semantic checks on the zone
content. The executed checks are the same as the checks run by the Knot
DNS server.

Please, refer to the ``semantic-checks`` configuration option in
:manpage:`knot.conf(5)` for the full list of available semantic checks.
