+This tool allows one to change (permanently) the MAC address
+of the SMSC 9221 Ethernet controller of Snowball boards.
+The address is written to the EEPROM of the controller to persist
+over reboots.
+To build the tool simply run
+ $ make
+assuming you have a cross-compiler set in your path. By default
+the compiler is expected to be "arm-linux-gnueabi-gcc", but if
+you want/need to use some other cross-compiler you can do so by
+redefining $CC on the command line:
+ $ make CC=my-funny-toolchain-gcc
+This will produce a statically linked binary that should be
+usable in almost any kind of image available for Snowball.
