+# introduced any errors when changing code.
+#
+# N.B., this only verifies that THIS build of dump(8) and THIS build of
+# restore(8) will play well together. It does not guarantee that these systems
+# are compatible with released versions of the software! For that we need
+# to keep images of known-good partitions and dump files.
