(description "The PowerDNS Authoritative Server is a versatile nameserver
which supports a large number of backends. These backends can either be plain
zone files or be more dynamic in nature. PowerDNS backends are datastores
that the server will consult and contains DNS records (and some metadata).
The backends range from database backends (MySQL, PostgreSQL) and BIND zone
files to co-processes and JSON APIs. Multiple backends can be enabled in the
configuration. Each backend can be configured separately.")
