-# 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".
