>Description:
        take for example:
        --- snip ---
        tucana# vnconfig â??u vnd0
        vnconfig: /dev/râ??ud: opendisk: No such file or directory
        tucana# vnconfig -u vnd0
        tucana#
        --- snip ---
        The first version was copied from the man page.

        Having synopsis, examples etc in manpages you can't actually use
        is a great way to get rid of new users and to annoy existing ones.

        .Fl needs to produce something that actually works.
        .Op Fl, too
