=head1 TUTORIAL

App::RemoteCommand or its frontend C<< rcommand >>
is a simple remote command launcher via ssh.
You can use it like C< ssh > command.

Let's say you have 6 hosts:

    www001.example.com, www002.example.com, www003.examle.com,
    www001.example.jp,  www002.example.jp,  www003.examle.jp

and you can ssh these hosts without password or passphrase.
If your ssh private key needs a passphrase, please setup C<ssh-agent> first.
