-# Arduino makefile
-#
-# This makefile allows you to build sketches from the command line
-# without the Arduino environment (or Java).
-#
-# The Arduino environment does preliminary processing on a sketch before
-# compiling it.  If you're using this makefile instead, you'll need to do
-# a few things differently:
-#
-#   - Give your program's file a .cpp extension (e.g. foo.cpp).
-#
-#   - Put this line at top of your code: #include <WProgram.h>
-#
-#   - Write prototypes for all your functions (or define them before you
-#     call them).  A prototype declares the types of parameters a
-#     function will take and what type of value it will return.  This
-#     means that you can have a call to a function before the definition
-#     of the function.  A function prototype looks like the first line of
-#     the function, with a semi-colon at the end.  For example:
-#     int digitalRead(int pin);
-#
-#   - Write a main() function for your program that returns an int, calls
-#     init() and setup() once (in that order), and then calls loop()
-#     repeatedly():
-#
-#	int main()
-#	{
-#		init();
-#		setup();
-#
-#		for (;;)
-#			loop();
-#
-#		return 0;
-#	}
-#
-# Instructions for using the makefile:
-#
-#  1. Copy this file into the folder with your sketch.
-#
-#  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 "ARDUINO" to point the directory that
-#     contains the Arduino core (for normal Arduino installations, this
-#     is the lib/targets/arduino sub-directory).
-#
-#  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. At the command line, change to the directory containing your
-#     program's file and the makefile.
-#
-#  6. Type "make" and press enter to compile/verify your program.
-#
-#  7. Type "make upload", reset your Arduino board, and press enter  to
-#     upload your program to the Arduino board.
