+Check supports running test suites with subunit output. This can be useful to
+combine test results from multiple languages, or to perform programmatic
+analysis on the results of multiple check test suites or otherise handle test
+results in a programmatic manner. Using subunit with check is very straight
+forward. There are two steps:
+1) In your check test suite driver pass 'CK_SUBUNIT' as the output mode
+for your srunner.
+@example
+@verbatim
+SRunner *sr;
+sr = srunner_create (make_s1_suite ());
+srunner_add_suite (sr, make_s2_suite ());
+srunner_run_all (sr, CK_SUBUNIT);
+@end verbatim
+@end example
+2) Setup your main language test runner to run your check based test
+executable. For instance using python:
+@example
+@verbatim
+
+import subunit
+
+class ShellTests(subunit.ExecTestCase):
+    """Run some tests from the C codebase."""
+
+    def test_group_one(self):
+        """./foo/check_driver"""
+
+    def test_group_two(self):
+        """./foo/other_driver"""
+@end verbatim
+@end example
+
+In this example, running the test suite ShellTests in python (using any test
+runner - unittest.py, tribunal, trial, nose or others) will run
+./foo/check_driver and ./foo/other_driver and report on their result.
+
+Subunit is hosted on launchpad - the @uref{https://launchpad.net/subunit/,
+subunit} project there contains bug tracker, future plans, and source code
+control details.
