17
# make coff = Convert ELF to AVR COFF.

19
# make extcoff = Convert ELF to AVR Extended COFF.
20
#
21
# make program = Download the hex file to the device, using avrdude.
22
#                Please customize the avrdude settings below first!
23
#
24
# make debug = Start either simulavr or avarice as specified for debugging, 
25
#              with avr-gdb or avr-insight as the front end for debugging.
26
#
27
# make filename.s = Just compile filename.c into the assembler code only.
28
