            Bug ID: 1341
           Summary: Usage message does not mention [file] argument
           Product: iptables
           Version: CVS (please indicate timestamp)
          Hardware: All
                OS: All
            Status: NEW
          Severity: trivial
          Priority: P5
         Component: iptables-restore
          Assignee: netfilter-buglog at lists.netfilter.org
          Reporter: matt at meinwald.name

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
