    # What the next line of script does: goes through the list of refs for all branches we push to github,
    # generates a snippet of shell which is evaluated. The snippet checks CI_BUILD_REF against the SHA
    # (aka objectname) at tip of each branch, and if any SHAs match then it checks out the local branch
    # and then pushes that ref to a corresponding github branch
    #
    # NB: In gitlab 9.x, CI_BUILD_REF was deprecated. New name is CI_COMMIT_REF. If below command suddenly
    # generates bash syntax errors, this is probably why.
