-should be a command).
+This file is a standalone program that reads commands on

-Usage: ./daemon.py <path_tofifo>
+Usage: cat some_fifo | ./daemon.py
 
-That fifo should be in a directory, shared through sshfs, with the remote

-executes them on the local machine.
+Poezio writes commands in the fifo, and this daemon executes them on the
+local machine.
 Note that you should not start this daemon if you do not trust the remote
 machine that is running poezio, since this could make it run any (dangerous)
 command on your local machine.
