+3. add a '<sources>' tag for your source file to tests/test.bkl
+
+
+III. Running the tests
+----------------------
+
+1. Regenerate the make/project files from test.bkl using bakefile_gen, e.g.:
+        cd build/bakefiles
+        bakefile_gen -b ../../tests/test.bkl
+   and if you're on a unix system re-run configure.
+
+2. Build the test program using one of the make/project files in the tests
+   subdirectory.
+
+3. Run the test program with no arguments to run the default set of tests
+   (which are all those registered with CPPUNIT_TEST_SUITE_REGISTRATION).
+   Or to list the test suites without running them:
+      test -l
+
+4. Tests that have been registered under a name using
+   CPPUNIT_TEST_SUITE_NAMED_REGISTRATION can also be run separately. For
+   example:
+      test MBConvTestCase
+   or to list the tests:
+      test -L MBConvTestCase
+
+
+IV. Notes
+---------
+
+1. You can register your tests (or a subset of them) just under a name, and not
+   in the unnamed registry if you don't want them to be executed by default.
+
+2. If you are going to register your tests both in the unnamed registry
+   and under a name, then use the name that the tests have in the 'test -l'
+   listing.
+
+3. Tests which fail can be temporarily registered under "fixme" while the
+   problems they expose are fixed, instead of the unnamed registry. That
+   way they can easily be run, but they do not make regression testing with
+   the default suite more difficult. E.g.:
+
+    // register in the unnamed registry so that these tests are run by default
+    //CPPUNIT_TEST_SUITE_REGISTRATION(wxRegExTestCase);
+    CPPUNIT_TEST_SUITE_NAMED_REGISTRATION(wxRegExTestCase, "fixme");
+
+    // also include in it's own registry so that these tests can be run alone
+    CPPUNIT_TEST_SUITE_NAMED_REGISTRATION(wxRegExTestCase, "wxRegExTestCase");
+
+4. Tests which take a long time to execute can be registered under "advanced"
+   instead of the unnamed registry. The default suite should execute reasonably
+   quickly. To run the default and advanced tests together:
+    test "" advanced
