"""
This plugins allows commands to be sent to poezio via a named pipe.
You can run the same commands that you would in the poezio input
(e.g. ``echo '/message toto@example.tld Hi' >> /tmp/poezio.fifo``).
Configuration
-------------
.. glossary::
:sorted:
pipename
**Default:** :file:`/tmp/poezio.fifo`
The path to the fifo which will receive commands.
