+# HOW TO USE THIS BUILD SCRIPT
+#
+# By default, this script will build the firmware for an atmega644p-based motherboard.
+# The firmware will be built, but not uploaded.
+#
+# To build for another platform, pass an explicit platform parameter.  For example,
+# $ scons platform=rrmbv12
+# $ scons platform=rrmbv22
+#
+# To upload the firmware, specify the "upload" target.  By default, this will use
+# /dev/ttyUSB0 as the serial connection.
+# $ scons upload
+#
+# If you want to select a port manually, specify it as a parameter:
+# $ scons port=/dev/ttyUSB3 upload
