The utilities in this directory are executable programs but are not
public-facing.  Nothing prevents you from executing or using the
utilities for your own purposes, but future versions of Mirrorrib can
alter the utilities' interfaces, change their operation, or remove them
without notice.  Future versions might not do those things, but can.

If you need a particular utility here to stabilize, then inform the
maintainer of your reason so that you and he can arrange a
suitable solution.
