The `make update-abi` method that Roland describes is part of the general
glibc `Release` documentation here and referenced from the `Release`
process followed by a release manager or machine maintainer during each
release:
https://sourceware.org/glibc/wiki/Regeneration
I'm happy to have more utility scripts added to `scripts/`, but I would
also like to hear what use cases this is intended to help with and have
those documented in the `Regeneration` document so developers can learn
how to use it.
Cheers,
Carlos.
