+  Note:
+      There are a number of different flags that you can use when building
+      udev.  They are as follows:
+	prefix
+		set this to the default root that you want udev to be
+		installed into.  This works just like the 'configure --prefix'
+		script does.  Default value is ''.  Only override this if you
+		really know what you are doing.
+	USE_KLIBC
+		if set to 'true', udev is built and linked against the
+		included version of klibc.  Default value is 'false'.
+	USE_LOG
+		if set to 'true', udev will emit messages to the syslog when
+		it creates or removes device nodes.  This is helpful to see
+		what udev is doing.  This is enabled by default.  Note, if you
+		are building udev against klibc it is recommended that you
+		disable this option (due to klibc's syslog implementation.)
+	USE_SELINUX
+		if set to 'true', udev will be built with SELinux support
+		enabled.  This is disabled by default.
+	DEBUG
+		if set to 'true', debugging messages will be sent to the syslog
+		as udev is run.  Default value is 'false'.
+	KERNEL_DIR
+		If this is not set it will default to /lib/modules/`uname -r`/build
+		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.
+
+      So, if you want to build udev using klibc with debugging messages, you
+      would do:
+	make USE_KLIBC=true DEBUG=true

-	- read the klibc/klibc/README file for how to set up the linux
