Yes, I meant scripts that generated the OSM files. I converted my
county's data (which has more attributes and is more recent than
TIGER, but feeds into it) to OSM files, which I documented here (not

attributes, or the simplifying I did):

It does take quite some practice to do correctly and efficiently.
