e.g. env PATH=/opt/gnu/bin:$PATH make test
+For FreeBSD you need to install latest gdb from ports or packages and
+provide path to it in TEST_GDB environment variable before executing
+the tests, native FreeBSD gdb does not not work. If you install
+coreutils, which provides GNU versions of basic utils like 'date' and
+'base64' on FreeBSD, the test suite will use these instead of the
+native ones. This provides robustness against portability issues with
+these system tools. Most often the tests are written, reviewed and
+tested on Linux system so such portability issues arise from time to
+time.

Running Tests
-------------
The easiest way to run tests is to say "make test", (or simply run the
<script>. If it yields success, test is considered
successful.
+ test_expect_code <code> <script>
+
+ This takes two strings as parameter, and evaluates the <script>.
+ If it yields <code> exit status, test is considered successful.
+
test_subtest_known_broken
Mark the current test as broken. Such tests are expected to fail.
