+# Arduino 0011 Makefile
+# Arduino adaptation by mellis, eighthave, oli.keller
+#
+# This makefile allows you to build sketches from the command line
+# without the Arduino environment (or Java).
+#
+# Detailed instructions for using the makefile:
+#
+# 1. Copy this file into the folder with your sketch. There should be a
+# file with the extension .cpp (e.g. foo.cpp)
+#
+# 2. Below, modify the line containing "TARGET" to refer to the name of
+# of your program's file without an extension (e.g. TARGET = foo).
+#
+# 3. Modify the line containg "INSTALL_DIR" to point to the directory that
+# contains the Arduino installation (for example, under Mac OS X, this
+# might be /Applications/arduino-0011).
+#
+# 4. Modify the line containing "PORT" to refer to the filename
+# representing the USB or serial connection to your Arduino board
+# (e.g. PORT = /dev/tty.USB0). If the exact name of this file
+# changes, you can use * as a wildcard (e.g. PORT = /dev/tty.USB*).
+#
+# 5. Set the line containing "MCU" to match your board's processor.
+# Older one's are atmega8 based, newer ones like Arduino Mini, Bluetooth
+# or Diecimila have the atmega168. If you're using a LilyPad Arduino,
+# change F_CPU to 8000000.
+#
+# 6. At the command line, change to the directory containing your
+# program's file and the makefile.
+#
+# 7. Type "make" and press enter to compile/verify your program.
+#
+# 8. Type "make upload", reset your Arduino board, and press enter to
+# upload your program to the Arduino board.
+#
+# $Id$
