    It is imporant, that before you do anything, install the travis Ruby gem.
    You need the ruby-dev environment as well, so
        apt install ruby-dev
        gem install travis (gem search travis - specific version)
        travis login

        Based on: http://blog.code4hire.com/2016/06/Adding-GitHub-token-to-Travis-CI-configuration/

    Commands:
        github-token: Adds a github token to all .travis files, recursively
          arguments: token or repo token, if you use 1 arguments, it is patrikx3
          make sure you are logged in travis.
