Thanks for the ideas all, I think go embed is the best path for me.
runtime/debug will give me the revision but sadly it can't give me the
branch.
I want the branch as we run a microservice architecture and seeing that all
the microservices are running
the release branch and not master (or main) is a useful cross check for our
QA dept; we have had cases of
them spending time checking development code which is - well, imperfect.
