# File 'documented/main/help_text.rb', line 237

def self.advanced_help
  <<~TEXT
    Lich Help: advanced

    Compatibility / advanced options:
      --gui
      --no-gui, --no-gtk  Run without the GTK GUI (aliases)
      --without-frontend
      --detachable-client=PORT|auto|HOST:PORT
      --pipe
      --frontend=NAME
      --frontend-command=CMD
      --game=HOST:PORT
      --bind-address=HOST

    Notes:
      The GTK GUI starts by default. To suppress it, pass --no-gui or --no-gtk,
      including when using --headless.
      Prefer --headless PORT or --headless auto for new headless launches.
      --pipe uses stdin/stdout as the client transport instead of a front-end socket.
      --bind-address=HOST sets the local address Lich binds its listen sockets to
      (the frontend, --game proxy, and detachable-client listeners).
      Defaults to 127.0.0.1.
      HOST -- in --bind-address, --headless, and --detachable-client alike -- may
      be an IP, a hostname, a keyword, or (with a port) a bracketed IPv6 literal
      such as [::1]:PORT. Keywords: tailscale (this machine's Tailscale address),
      lan (its private LAN address), or any (0.0.0.0). Lich's listen sockets are
      unauthenticated - anyone who can reach one controls the session - so
      prefer tailscale over lan or any.
      Multiple frontends may attach to one detachable port. Each receives game
      output, and commands from all attached frontends are processed serially.
      Compatibility flags remain supported but are intentionally omitted from the default help screen.
