Release management: how do you update the libtool version information?

[Vivien Kraus]

Dear gnulib people,

How do you manage the libtool version information for a library using
gnulib? For now, I have it written down explicitly in configure.ac.
Unfortunately, this requires a new commit to bump the numbers before
each release.

Gnulib provides a script to help update the libtool version
information. Is there a way to involve that script in the "make
release-commit" invocation? It is a little awkward to create a commit
just to bump the libtool version information, or to squash it with the
commit created by "make release-commit".

My current solution involves a bit of cheating: fix do-release-commit-
and-tag not to complain about a dirty tree, and have the libtool update
already staged when running make release-commit.

Am I missing something here? How do you update the libtool version
information?

Best regards,

Vivien
