-Automatic HTML Report Generation
+Coverage Reports (Experimental)
================================
-If ``*SAN_OPTIONS`` contains ``html_cov_report=1`` option set, then html
-coverage report would be automatically generated alongside the coverage files.
-The ``sancov`` binary should be present in ``PATH`` or
-``sancov_path=<path_to_sancov`` option can be used to specify tool location.
+``.sancov`` files do not contain enough information to generate a source-level
+coverage report. The missing information is contained
+in debug info of the binary. Thus the ``.sancov`` has to be symbolized
+to produce a ``.symcov`` file first:
+
+.. code-block:: console
+ sancov -symbolize my_program.123.sancov my_program > my_program.123.symcov
+
+The ``.symcov`` file can be browsed overlayed over the source code by
+running ``tools/sancov/sancov-report-server.py`` script that will start
+an HTTP server.
How good is the coverage?
