.IP "\fB\-\-peer\-ca\-cert=\fIpeer-cacert.pem\fR"
Specifies a PEM file that contains one or more additional certificates
to send to SSL/TLS peers.  \fIpeer-cacert.pem\fR should be the CA
certificate used to sign \fB\*(PN\fR's own certificate, that is, the
certificate specified on \fB\-c\fR or \fB\-\-certificate\fR.  If
\fB\*(PN\fR's certificate is self-signed, then \fB\-\-certificate\fR
and \fB\-\-peer\-ca\-cert\fR should specify the same file.
.IP
This option is not useful in normal operation, because the SSL/TLS peer
must already have the CA certificate for the peer to have any
confidence in \fB\*(PN\fR's identity.  However, this offers a way for
a new installation to bootstrap the CA certificate on its first SSL/TLS
connection.
