6# On command line:
7#
8# make all = Make software.
9#
10# make clean = Clean out built project files.
11#
12# make coff = Convert ELF to AVR COFF.
13#
14# make extcoff = Convert ELF to AVR Extended COFF.
15#
16# make program = Download the hex file to the device, using avrdude.
17# Please customize the avrdude settings below first!
18#
19# make debug = Start either simulavr or avarice as specified for debugging,
20# with avr-gdb or avr-insight as the front end for debugging.
21#
22# make filename.s = Just compile filename.c into the assembler code only.
23#
24# make filename.i = Create a preprocessed source file for use in submitting
25# bug reports to the GCC project.
26#
27# To rebuild project do "make clean" then "make all".
