+ * int plugin_init_i2c_sensors (void)
+ * adds function i2c_sensors() to retrieve informations from
+ * the i2c sensors via the sysfs interface of 2.6.x kernels
+ *
+ * -- WARNING --
+ * This plugin is only for kernel series 2.5/2.6 and higher !
+ * It uses the new sysfs pseudo-filesystem that you can mount with:
+ * mount -t sysfs none /sys
+ *
+ * -- WARNING #2 --
+ * This plugin should detect where your sensors are at startup.
+ * If you can't get any token to work, ensure you don't get
+ * an error message with "lcd4linux -F".
+ *
+ * If so, try to force the path to your sensors in the conf like this :
+ * i2c_sensors.path /sys/bus/i2c/devices/0-6000/
+ *
+ * - replace 0-6000 with the appropriate dir
+ * - DON'T forget the trailing slash or it won't work !
