+
+This option enables the output of debug information when running the
+various test commands. (default: off)
+
+=item B<--diff>
+
+Use C<diff -u> for comparing the expected output with the produced
+output. (default: use a built-in routine)
+
+=item B<--flavor>|B<--flavour> I<flavour>
+
+Override the expected results for results for a specific (OS) flavour.
+(default: unused)
+
+=item B<--[no]ipv4>
+
+Skip IPv4 related setup and tests (default: use ipv4)
+
+=item B<--[no]ipv6>
+

+
+=item B<--keep>
+
+Keep the various output files produced during a test run. (default: don't keep)
+
+=item B<--range> I<n0> I<n1>
+
+Run tests between (including) I<n0> and I<n1>. A "+" may be used to specify the "last

+
+=item B<--slow>
+
+Insert some delays to compensate for a slow host system. (default: off)
+
+=item B<--test> I<n>

+=item B<--update>
+
+Automatically update the recorded (expected) data on mismatch. (default: off)
