Oops, sorry, again.  What I meant is that the ndb file format is not
self-explanatory.  A zone file for in-addr.arpa _is_ analogous to any
other forward-lookup zone, but Plan 9 has a somewhat different
approach and I can't seem to glean the full scope from the man pages.

I think it needs to be clarified at the possible cost of repetition,
if only for my benefit.
