# make all = Make software.

|

# make clean = Clean out built project files.

# make coff = Convert ELF to AVR COFF (for use with AVR Studio 3.x or VMLAB).

# make extcoff = Convert ELF to AVR Extended COFF (for use with AVR Studio
|
|
# 4.07 or greater).

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