+
+In addition to the normal C<-l>/C<--listen> switch described in
+L<public-inbox-daemon(8)>, the protocol prefix (e.g. C<nntp://> or
+C<nntps://>) may be specified to force a given protocol.
+
+For STARTTLS and NNTPS support, the C<cert> and C<key> may be specified
+on a per-listener basis after a C<?> character and separated by C<,>.
+These directives are per-directive, and it's possible to use a different
+cert for every listener.
+
+=item --cert /path/to/cert
+
+The default TLS certificate for optional STARTTLS and NNTPS support
+if the C<cert> option is not given with C<--listen>.
+
+If using systemd-compatible socket activation and a TCP listener on port
+563 is inherited, it is automatically NNTPS when this option is given.
+When a listener on port 119 is inherited and this option is given, it
+automatically gets STARTTLS support.
+
+=item --key /path/to/key
+
+The default private TLS certicate key for optional STARTTLS and NNTPS
+support if the C<key> option is not given with C<--listen>.  The private
+key may concatenated into the path used by C<--cert>, in which case this
+option is not needed.
