+## Running unit tests with gcov
+
+Enable unit test gcov code coverage analysis by configuring gcov reporting
+directory:
+
+    configure --with-gcov-report-dir=DIR
+
+Directory can be an absolute path or a relative path to an SDL source root.
+Unit test build creates directory if it does not exist.

+Build and run unit tests with code coverage analysis:

+After successful unit test run code coverage (.gcov) result files are in
+a directory, what was defined by '--with-gcov-report-dir' configure option.

+In addition, graphical gcov front-ends such as lcov can be used for coverage
+analysis:
+
+	lcov --directory tst/ --directory src --capture --output-file coverage.info
+	genhtml coverage.info --output-directory out

+Open the out/index.html using any web browser.
