-        machine where poezio is running, and accessible (through sshfs for
-        example) from the local machine (where poezio is not running). A
-        very simple daemon (daemon.py) reads on that fifo, and executes any
-        command that is read in it. Since we can only write strings to that
-        fifo, each argument has to be pipes.quote()d. That way the
-        shlex.split on the reading-side of the daemon will be safe.
-
-        You cannot use a real command line with pipes, redirections etc, but
-        this function supports a simple case redirection to file: if the
-        before-last argument of the command is ">" or ">>", then the last
-        argument is considered to be a filename where the command stdout
-        will be written. For example you can do exec_command(["echo",
-        "coucou les amis coucou coucou", ">", "output.txt"]) and this will
-        work. If you try to do anything else, your |, [, <<, etc will be
-        interpreted as normal command arguments, not shell special tokens.
