* options Used to specify additional options to the configuration settings; useful for specifying options for which there is no separate constructor argument. This is analogous to the -o command line flag to the ssh program. If used, the value should be a reference to a list of option directives in the format used in the config file. For example: my $ssh = Net::SSH::Perl->new("host", options => [ "BatchMode yes", "RhostsAuthentication no" ]);
