+# How we currently test 'svnfsfs' --
+#
+#   'svnadmin create':   Create an empty repository, test that the
+#                        root node has a proper created-revision,
+#                        because there was once a bug where it
+#                        didn't.
+#
+#                        Note also that "svnadmin create" is tested
+#                        implicitly every time we run a python test
+#                        script.  (An empty repository is always
+#                        created and then imported into;  if this
+#                        subcommand failed catastrophically, every
+#                        test would fail and we would know instantly.)
+#
+#   'svnadmin createtxn'
+#   'svnadmin rmtxn':    See below.
+#
+#   'svnadmin lstxns':   We don't care about the contents of transactions;
+#                        we only care that they exist or not.
+#                        Therefore, we can simply parse transaction headers.
+#
+#   'svnadmin dump':     A couple regression tests that ensure dump doesn't
+#                        error out, and one to check that the --quiet option
+#                        really does what it's meant to do. The actual
+#                        contents of the dump aren't verified at all.
