Last I checked, there were over 400 repositories on GitHub using ocaml-ci-scripts.  It's pretty stable.

Why do you need direct integration with Travis?  The use of the Docker support has made the necessity for that essentially obsolete.

See, for example:
https://github.com/mirage/ocaml-cohttp/blob/master/.travis.yml <https://github.com/mirage/ocaml-cohttp/blob/master/.travis.yml>

in cohttp, which uses Travis and Docker to test the libraries on a variety of Linux distributions.

This solution is pretty good for most people. I'd encourage you to give it a try, and to contribute back any improvements or feature requests you might have after trying it out for a while.
