10  excludes:     A shell script which defines test cases that are to be skipped,
11                or aren't expected to pass.
12  category:     The test category, in the form of <arch>/<feature>. For example,
13                "common/aggs" is the test category for D aggregations.
14  testfiles:    The test files for the tests in the specified category.
