    # Mindless copy and paste command:

    #   # Standard Linux / GNU tools
    #   wget -O ~/.tmux.conf https://andrew-quinn.me/tmux-conf.txt
    #   curl -fsSL https://andrew-quinn.me/tmux-conf.txt -o ~/.tmux.conf
    #   busybox wget -q -O ~/.tmux.conf https://andrew-quinn.me/tmux-conf.txt
    # [... many, many others]
