+# Hey Emacs, this is a -*- makefile -*-

+#----------------------------------------------------------------------------

+# WinAVR Makefile Template written by Eric B. Weddington, J�rg Wunsch, et al.

+#

+# Released to the Public Domain

+#

+# Additional material for this makefile was written by:

+# Peter Fleury

+# Tim Henigan

+# Colin O'Flynn

+# Reiner Patommel

+# Markus Pfaff

+# Sander Pool

+# Frederik Rouleau

+#

+#----------------------------------------------------------------------------

+# On command line:

+#

+# make all = Make software.

+#

+# make clean = Clean out built project files.

+#

+# make coff = Convert ELF to AVR COFF.

+#

+# make extcoff = Convert ELF to AVR Extended COFF.

+#

+# make program = Download the hex file to the device, using avrdude.

+#                Please customize the avrdude settings below first!

+#

+# make debug = Start either simulavr or avarice as specified for debugging, 

+#              with avr-gdb or avr-insight as the front end for debugging.

+#

+# make filename.s = Just compile filename.c into the assembler code only.

+#

+# make filename.i = Create a preprocessed source file for use in submitting

+#                   bug reports to the GCC project.

+#

+# To rebuild project do "make clean" then "make all".

+#     This will define a symbol, F_CPU, in all source code files equal to the

+#     automatically to create a 32-bit value in your source code.

+#     Even though the DOS/Win* filesystem matches both .s and .S the same,
