Hi Curt,
1.Run: Read all relations and store their dependencies (maybe in a
very simple database, or even in RAM) Then figure out which relations
you *really* need. 2. Run

Hi Curt,
is there an easy way to extract only national boundaries from an

Hi Curt,
the relation 11980 seems to be a part of an experiment/proposal to make
the big boundary relations easier to handle (for some definition of
easy - it definitely doesn't make it easier to _filter_ them...):
