<pre>The optional [file] argument is documented in the manpage, but is not present
in the usage message as of the latest commit I see
(093cec72e7f7793d55fa1547cadb6655104feb5e).
It looks like this feature has been available for quite some time, but was only
added to the manpage in 2015. I propose the following trivial update to bring
the usage message in sync as well:
diff --git a/iptables/xtables-restore.c b/iptables/xtables-restore.c
index 86f6a3a..13b9320 100644
--- a/iptables/xtables-restore.c
