+This is the buildsystem for the OpenWrt Linux Distribution
+It is a modified uClibc buildroot2.
+
+Please use "make menuconfig" to configure your appreciated
+configuration for the toolchain and firmware.
+
+Simply running 'make' will build your firmware and a tarball
+of kernel modules. It will download all sources, build the 
+cross-compile toolchain, the kernel and all choosen applications.
+
+You can use flash.sh for remotely updating your embedded system
+via tftp.
+
+
+There are some cleanup targets we would like to explain.
+"make clean" will only clean the firmware images and the root
+filesystem. "make dirclean" will remove the extracted kernel source
+and all exctracted software. (busybox,bridge-utils,..), but will
+preserve your toolchain. (compiler,linker,..)
+"make distclean" will remove everything, including the toolchain, 
+all downloaded source code archives and your firmware configuration. 
+You can cleanup separate directories by using "make application-dirclean" 
+and rebuild the firmware with "make".
+
+Be happy..
+	Your OpenWRT Project
+	http://www.openwrt.org
