+
+        The remote execution is done
+        by writing the command on a fifo.  That fifo has to be on the
+        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.
