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".
