    Dockerfile in the root when only building a single command
  - `Makefile` - includes `release-tools/build.make` and sets
    configuration variables
- - `.travis.yml` - a symlink to `release-tools/.travis.yml`
+ - `.prow.sh` script which imports `release-tools/prow.sh`
+   and may contain further customization
+ - `.cloudbuild.sh` and `cloudbuild.yaml` as symlinks to
+   the corresponding files in `release-tools` or (if necessary)
+   as custom files
 
 To create a release, tag a certain revision with a name that
 starts with `v`, for example `v1.0.0`, then `make push`
