+# - Fix mismatches in relative file paths within the test target

+#   existing tests.
+#
+# - Verify that the port does not reference the latest list.
+#
+#   - Compare the latest list with the built-in list.
+#
+#   - Detect unintended use of the latest list by testing a suffix such as
+#     zabc.net, an entry in the latest list that is not present in the
+#     built-in list.
+#
+#[notes]
+# the latest list:   installed public suffix list
+# the built-in list: default or embedded public suffix list
