+=item --ng NEWSGROUP
+
+=item --newsgroup NEWSGROUP
+
+The NNTP group name for use with L<public-inbox-nntpd(8)>. This
+may be any newsgroup name with hierarchies delimited by C<.>.
+For example, the newsgroup for L<mailto:meta@public-inbox.org>
+is: C<inbox.comp.mail.public-inbox.meta>
+
+This may be set after-the-fact via C<publicinbox.$NAME.newsgroup>
+in the configuration file. See L<public-inbox-config(5)> for more
+info.
+
+Available in public-inbox 1.6.0+.
+
+Default: none.
+
+=item -c KEY=VALUE
+
+Allow setting arbitrary configs as C<publicinbox.$NAME.$KEY>.
+This is idempotent for the same C<VALUE>, but allows setting
+multiple values for keys such as C<publicinbox.$NAME.url> and
+C<publicinbox.$NAME.watch>.
+
+=item --skip-artnum
+
+This option allows archivists to publish incomplete archives
+with only new mail while allowing NNTP article numbers
+to be reserved for yet-to-be-archived old mail.
+
+This is mainly intended for users of C<--skip-epoch> (documented below)
+but may be of use to L<public-inbox-v1-format(5)> users.
+
+There is no automatic way to use reserved NNTP article numbers
+when old mail is found, yet.
+
+Available in public-inbox 1.6.0+.
+
+Default: unset, no NNTP article numbers are skipped
