- * FFIO menu plugin
- * Provides a menu from a FIFO located in ~/.openbox/fifo_menu/id
- * Example:
- * rc3:
- * <menu id="fonk" label="fonk" plugin="fifo_menu"></menu>
- * Menu format
- * <fifo_menu>
- * <item label="GLOVE.png">
- * <action name="execute">
- * <execute>
- * bsetbg "/home/woodblock/.openbox/backgrounds/GLOVE.png"
- * </execute>
- * </action>
- * </item>
- * </fifo_menu>
- *
- * If the attribute pid="true" is in the <menu>
