These tools depend upon DNSjava (<https://github.com/dnsjava/dnsjava>), the Jakarta Commons CLI and Logging libraries (<https://commons.apache.org/proper/commons-cli>), slf4j (<https://www.slf4j.org>), and Sun's Java Cryptography extensions. A copy of each of these libraries is included in the distribution.
4. You can build the distribution tarballs with 'ant dist'. You can run the tools directly from the build area (without building the jdnssec-tools.jar file) by using the ./bin/\_jdnssec_* wrappers.
