FIFO menus are the only plugin that takes advantage of this.
Example:
<menu id="root" label="Openbox 3">
<menu id="fonk" label="fonk" plugin="fifo_menu">
</menu>
</menu>
This creates a FIFO ~/.openbox/fifo_menu/fonk to which you can send
menus to. The menus sent to it must be like
<fifo>
<item>
etc...
</fifo>
I think. If my memory serves me right.
It is all hideous, but I just wanted to experiment and see if it was
possible.
order te startup so that plugins can set up their config shit before parsing the config, then the config is parsed, engine is loaded, and finally the plugins are officially started.
