    longDescription = ''
      getdns is an implementation of a modern asynchronous DNS API; the
      specification was originally edited by Paul Hoffman. It is intended to make all
      types of DNS information easily available to application developers and non-DNS
      experts. DNSSEC offers a unique global infrastructure for establishing and
      enhancing cryptographic trust relations. With the development of this API the
      developers intend to offer application developers a modern and flexible
      interface that enables end-to-end trust in the DNS architecture, and which will
      inspire application developers to implement innovative security solutions in
      their applications.
