Finished posting feats.
A tweak to the script became a complete rewrite. This version strips out newlines, closes the file, then starts over. Solves many weirdness problems. This time, far better documented, including such wonderful comments as, # This breaks something if I do this earlier.
This was "fast iteration" development. Each edit/test only tested one thing.
I won't be getting too much into the next big task as I'll be away over the weekend.
