# Makefile for AVR function library development and examples
# Author: Pascal Stang
#
# For those who have never heard of makefiles: a makefile is essentially a
# script for compiling your code.  Most C/C++ compilers in the world are
# command line programs and this is even true of programming environments
# which appear to be windows-based (like Microsoft Visual C++).  Although
# you could use AVR-GCC directly from the command line and try to remember
# the compiler options each time, using a makefile keeps you free of this
# tedious task and automates the process.
#
# For those just starting with AVR-GCC and not used to using makefiles,
# I've added some extra comments above several of the makefile fields which
# you will have to deal with.
