/// tip

All this might seem contrived. And it might not be very clear how is it useful yet.

These examples are intentionally simple, but show how it all works.

In the chapters about security, there are utility functions that are implemented in this same way.

                "Expected contributors to contain " + contributor + " but was " + merged.getContributors());
    }
