Tail the output of the running job identified by its serial number.
Use the I<--jobs> flag to get a list of running jobs.
+=item B<--test> variable=value [variable=value ...]
+
+This works the same way as the I<--set> option, but the difference is
+that the variables are set. Instead, it lists out the jobs that
+I<would> run, I<if> the variables were updated to these new values.
+
+The variables are not actually updated, and the jobs are not actually
+run.
+
+The output is a list of job names that would run.

=item B<--upload>
