 # The function ``tribits_add_advanced_test()`` can be used to add tests in
 # non-TriBITS projects.  To do so, one just needs to set the variables
-# ``PROJECT_NAME``, ``PACKAGE_NAME`` (which could be the same as
-# ``PROJECT_NAME``), ``${PACKAGE_NAME}_ENABLE_TESTS=TRUE``, and
-# ``${PROJECT_NAME}_TRIBITS_DIR`` (pointing to the TriBITS location).  For example,
