                This is used if USE_KLIBC=true to find the kernel include
                directory that klibc needs to build against.  This must be set
                if you are not building udev while running a 2.6 kernel.

+               as listed (see below for an example.)
 
       So, if you want to build udev using klibc with debugging messages, you
       would do:
        make USE_KLIBC=true DEBUG=true
 
+      If you want to build the udev helper program cdrom_id and scsi_id you
+      would do:
+       make EXTRAS="extras/cdrom_id extras/scsi_id"

       udev will follow the setting of the debug level in udev.conf. Adapt this
       value to see the debug in syslog.
