Assuming we have a number of feature branches, we may well have to
resolve conflicts among them, so an integration branch seems like
the right way forward. So unless we just build the package from the
integration branch to produce a monolithic patch, your algorithm is
something to focus on! I am still not convinced that it is possible
to extract historic patches from the ancestry of a tag on the
integration branch, but I'd love to be proven wrong! Unfortunately,
I won't be able to look into this again before next week.
