Zone generation is possible via simple command bellow. Zone is Bind9 compatible and can be signed by any DNSSEC tool for Bind9.
NOTICE: For correct zone generation, you must first configure nameservers (NS records) for your TLD in GUI (menu TLD)
# ./rreg -c config.yaml -zonefile <tld> > yourzone.db
# ./rreg -c config.yaml -zonefile tld
