AH, thanks for pointing me at thatt file!! It makes a whole lot of things
clearer. Now I understand how Nagios "views" the world. Looks like there a
re a number of different ways to acheive the same end result, and I would
spsect that each one of those makes sense at some time and place to some
person. Not all of them make sense to me at the moment, but thta is OK.

Thanks, again.
