It's code that was contributed over ten years ago; we put it into dig
(hidden behind #ifdef's) because at the time there was no better
alternative, but we never formally supported it.  It's buggy and
broken in a number of edge cases and hasn't really kept up with the
evolution of DNSSEC.

Please try "delv" and if you find that it doesn't meet your needs,
let me know so I can try to improve it.

NLNetLabs's "drill" is also useful.

No, delv is built and installed in BIND 9.10 and higher.
