I know most of these hooks are maintained individually, but it might be nice with each new version branch of MESA to create a new version branch here as well. That way when the procedures are (or are not) updated with each version they are tagged/included appropriately with the versions of MESA they are compatible with. It would help to make it more clear when a specific procedure is no longer being maintained for newer versions of MESA.
