RoutinesGit is not currently supported. Evaluated whether to support them in the future; in the meantime, you will need to track any submodules in the main project. You can do it as follows:
$ cd myapp
$ rm -rf `find . -mindepth 2 -name .git`
$ git rm --cache `git submodule | cut -f2 -d' '`
$ git rm .gitmodules
$ git add .
$ git config -l | grep '^submodule' | cut -d'=' -f1 | xargs -n1 git config --unset-all
$ git commit -m "brought submodules into the main repo"
, , :
$ find . -mindepth 2 -name .git
, .
