=head1 get-ssl.pl

Output SSL certificate information for a domain.

Given a domain name with the C<--domain> flag, this command outputs 
information about the SSL certificate currently in use by that virtual server.

If the C<--chain> flag is given, details of the CA certificate will be
shown instead (if there is one).
