@native-api: Thanks for the link. It appears that I’ll need to get comfortable with submodules.

But you can help me with one question before I go charging down the wrong path: To facilitate usage, `mulib` library is minimal by design and does not contain the unit tests. Rather, I chose to do it the other way around: `mulib-support` contains the unit tests, and conceptually owns `mulib` as a submodule (although at present it’s just a subdirectory, not a submodule).

Given that: can I assume that all the instructions you gave in [How to trigger a build in the test project upon a commit to dev project with Travis CI API - #2 by native-api](https://travis-ci.community/t/how-to-trigger-a-build-in-the-test-project-upon-a-commit-to-dev-project-with-travis-ci-api/11523/2) still apply as long as I flip the meanings of `test repo` and `dev repo`?
