====== FIFO plugin ======

===== example config =====
Here is my (michu / neophob.com) fifo widget config:
<code>
Plugin FIFO {
    FifoPath '/tmp/lcd4linux.fifo'
    FifoBufSize 80
}	    

Widget fifo {
    class 'Text'
    expression fifo::read()
    width 20
    align 'L'
    speed scroller
    update 500
}

...
</code>


===== Usage =====
You may use BASH to add a message to LCD4Linux:
<code>
 # echo Hello FIFO Plugin! > /tmp/lcd4lnx.fifo
</code>


Now LCD4Linux will display "Hello FIFO Plugin!":
<code>
┌────────────────────┐
│Hello FIFO Plugin!  │
│                    │
└────────────────────┘

┌──Stderr:────────────────────────────────────────────────────────────────────────────────────────────────────────────┐
│initializing layout 'Default'                                                                                        │
│lcd4linux.c: starting main loop                                                                                      │
...
</code>
