    longDescription = ''
      ferm is a tool to maintain complex firewalls, without having the trouble to
      rewrite the complex rules over and over again. ferm allows the entire
      firewall rule set to be stored in a separate file, and to be loaded with one
      command. The firewall configuration resembles structured programming-like
      language, which can contain levels and lists.
