       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.
