#
# This makefile will
#  - download the specified version of the Arduino IDE
#  - compile the necessary files and create a library out of them
#  - create a header file for including in your Arduino programs
#  - install the header and library on your system
#
# To do all this, put this makefile in an empty directory and type
# "make install".  Type "make deinstall" to undo.
#
# Only tested with Arduino Duemilanove with ATmega328p.  May work with
# others, but then again, it may not.
#
# You will need:
#  - avr-gcc
#  - avr-binutils
#  - wget
#  - sed
#  - m4
