Description-en: reconfiguration tool to make DNSSEC work
Dnssec-trigger reconfigures the local unbound DNS server. This unbound
DNS server performs DNSSEC validation, but dnssec-trigger will signal
it to use the DHCP obtained forwarders if possible, and fallback to
doing its own AUTH queries if that fails, and if that fails prompt the
user via dnssec-trigger-applet the option to go with insecure DNS
only.
