      tmux is a terminal multiplexer, like e.g. screen, which gives you a
      possibility to use multiple virtual terminal session within one real
      terminal session. tmux-cssh (tmux-cluster-ssh) sets a comfortable and
      easy to use functionality, clustering and synchronizing virtual
      tmux-sessions, on top of tmux. No need for a x-server or x-forwarding.
      tmux-cssh works just with tmux and in an low-level terminal-environment,
      like most server do.
