This file is a standalone program that reads commands on
|
||
stdin and executes them (each line should be a command).
|
||
|
||
Usage: cat some_fifo | ./daemon.py
|
||
|
||
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.
