Add .Nm.
Options: -> The following options are available:

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,

the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
