It required some special fiddling with the submodules to get them right. I first manually fixed .gitmodules, and the git remotes in the 3 submodule folders, and after that i ran the following:

To get all parts in synch:

• git fetch
• git checkout master
• git submodule foreach git fetch
• git submodule foreach git checkout master

Then to pile on top of latest, and reset manual tweaks just to be sure:

• git pull --rebase
• git submodule update --remote --rebase
• git submodule foreach git reset --hard origin/master

After this a git commit of ref updates (ran than a few times with --amend and push -f to get above procedure right)..

Again, held off with deprecation message until grove-cli has been migrated and released..
