WIP: restructure

A stupid attempt to reduce code duplication led me to believe that all
the scripts could use _a bit_ of refactoring.
This is going to be a major pain (factoring out all the things), which
I'll take gladly.
All the links and usage examples are broken right now, but nobody cares,
so whatevs.
