-`test.sh` is the testing equivalent of `bench.sh`. It can be used to
-run selected test groups conveniently. You can run tests with coverage
-and view hpc coverage report. You can also pass GHC RTS options when
-running tests. `tests.sh` runs the tests with restricted memory, see
-`bin/test.sh` for details on the amount of memory used or to change it.
