	The "lamers" tool just takes what BIND gives it in the log.  This 
is not something that I believe "doc" checks today, but I may be 
wrong.  If so, then this needs to be fixed.

	However, my real question was based on the algorithm that I, as a 
human being, make use of.  This tool may/may not be easier to fix.

	Hmm.  So, they own all fourteen of the *.gtld-servers.net 
machines, unlike the *.root-servers.net machines which are operated 
by a variety of organizations around the world?  Interesting, I had 
no idea....
