+support.  DNSSEC with NSEC validation for negative records, is complete.  The
+client supports dynamic DNS with SIG0 authenticated requests, implementing
+easy to use high level funtions.  Trust-DNS is based on the Tokio and Futures
+libraries, which means it should be easily integrated into other software that
+also use those libraries.")
