in them, or what I need, other than by downloading them and inspecting
As a packager, what should I do? For now, I will include the main file
in the package, following tradition, and not worry about the new ones.
I am guessing that this means the grids for the important datums are
still in the main file, even if they are a North American Datum, and the
north-america file contains only more obscure datums that were not
previously available. I originally had the impression that all North
American grids were demoted from the main file to the regional file.
I updated my draft 5.0.0 package to use proj-datumgrids-1.7RC2, and I
see that this added two files compared to 1.5 (which I should have
