I think there is a possibility going forward that other tools may
want to use these libraries, for example, to parse package/repository
manifests, etc. At least that's the reason we have them in the first
place.

Right. The good news is this should all be sorted out once we release
the next version of ODB and a stable version of build2. So if we can
limp along like this for a while long, that would probably be the
easiest.

Yes, that sounds like a reasonable approach to me.

Yes, those are runtime requirements. Strictly speaking, git is only
necessary if one wants to work with git-based repositories.

To be complete, these are the tools that might be invoken by the toolchain
in certain situations:

gz
tar
git
curl
diff
install
openssl
