+# `make test` takes really long, so disable it. It also succeeds (i.e. returned value is zero) in
+# case of unexpected failures. There are always unexpected failures.
+# If you really want to run the tests, then enable expensive tests in order to run `make fulltest`,
+# which runs the same tests as `make test`, but includes more test cases per test.
