Right but are they not recreated when the corresponding py file is
accessed? So the speed to would only apply to the first run after

Good point. I'll look at that.

That is a feature :-) I guess I need to work on that a bit. It seems

compressed. Or I am otherwise somehow loosing the formatting from the
original dmg. I need to look at the new-create-dmg and use that.
