=head1 DESCRIPTION
Print out a usage message.
-=item B<-connect host:port>
+=item B<-connect> I<host>:I<port>
This specifies the host and optional port to connect to.
-=item B<-www page>
+=item B<-www> I<page>
This specifies the page to GET from the server. A value of '/' gets the
index.htm[l] page. If this parameter is not specified, then B<s_time> will only
perform the handshake to establish SSL connections but not transfer any
payload data.
-=item B<-cert certname>
+=item B<-cert> I<certname>
The certificate to use, if one is requested by the server. The default is
not to use a certificate. The file is in PEM format.
-=item B<-key keyfile>
+=item B<-key> I<keyfile>
The private key to use. If not specified then the certificate file will
be used. The file is in PEM format.
-=item B<-verify depth>
+=item B<-verify> I<depth>
The verify depth to use. This specifies the maximum length of the
server certificate chain and turns on server certificate verification.
with a certificate chain can be seen. As a side effect the connection
will never fail due to a server certificate verify failure.
-=item B<-nameopt option>
+=item B<-nameopt> I<option>
Option which determines how the subject or issuer names are displayed. The
-B<option> argument can be a single option or multiple options separated by
+I<option> argument can be a single option or multiple options separated by
commas. Alternatively the B<-nameopt> switch may be used more than once to
set multiple options. See the L<x509(1)> manual page for details.
-=item B<-CApath directory>
+=item B<-CApath> I<directory>
The directory to use for server certificate verification. This directory
must be in "hash format", see B<verify> for more information. These are
also used when building the client certificate chain.
-=item B<-CAfile file>
+=item B<-CAfile> I<file>
A file containing trusted certificates to use during server authentication
and to use when attempting to build the client certificate chain.
that session caching is working. If neither B<-new> nor B<-reuse> are
specified, they are both on by default and executed in sequence.
-=item B<-ssl3>
-
-This option disables the use of SSL version 3. By default
-the initial handshake uses a method which should be compatible with all
-servers and permit them to use SSL v3 or TLS as appropriate.
-
-The timing program is not as rich in options to turn protocols on and off as
-the L<s_client(1)> program and may not connect to all servers.
-Unfortunately there are a lot of ancient and broken servers in use which
-cannot handle this technique and will fail to connect. Some servers only
-work if TLS is turned off with the B<-ssl3> option.

+These options enable specific SSL or TLS protocol versions for the handshake

+By default B<s_time> negotiates the highest mutually supported protocol

OpenSSL was built.
=item B<-bugs>
There are several known bugs in SSL and TLS implementations. Adding this
option enables various workarounds.

L<ciphers(1)> for more information.
-=item B<-ciphersuites val>

This allows the TLSv1.3 ciphersuites sent by the client to be modified. This
list will be combined with any TLSv1.2 and below ciphersuites that have been
