% This is a set of utilities that I have used in London
% to print large files to an HP 6xx series plotter.
% At least the way I use it, this plotter handles the top
% margin in a bizzare way that requires some preprocessing
% to get things into a predictable location on the physical
% page.  I don't provide any documentation here, because the
% chances are good that my problems were one-off problems.
% But it you, too, have trouble with HP 6xx series plotters
% and dvips, I will be happy to explain how this stuff works
% together (if I can remember).
