It's git-update-ref.

That would be similar to git commit, not git checkout, right?  Oh
wait, I see the confusion: git checkout does two things.  It switches
branches, and it checks out files from the index into the work tree.
I meant the latter meaning.

Er, sorry, yes. It should be "git symbolic-ref", of course, to change
HEAD, and then probably read-tree and checkout-index. I was just not
thinking when I wrote the other message (hopefully I am doing so now).

Consider "git commit", for example. Does anyone
actually script around "write-tree" and "commit-tree" these days, or do
they just script around "git commit"?

Oh, I use those all the time.  They're awesome!  It allows you to
create commits without having a working tree, which lets me do very
interesting tricks.  git-subtree uses this heavily.

I'm probably a weirdo, though.

OK, I should have phrased my statement differently (see, I told you I
wasn't thinking). Yes, there are reasons to script around low-level
building blocks, when you don't want the assumptions associated with the
higher level. But I'm sure there are tons of scripts that munge some
files in a worktree, followed by "git add -A; git commit -m 'automagic
update'". And in that case, nobody would script around "commit-tree"
because it's a lot more work.
