				 AVR extras:
				
				   debug    : compile with minimal optimization and debug symbols
				   debugopt : compile with debug symbols
				   xnp      : compile for network programming
				
				 Programmer options:
				
				   dapa         : (default) use parallel port programmer
				   mib510, : use MIB510/MIB520 serial port programming board at port 
				   eprb,	: use EPRB at hostname 
				   avrisp, : use AVRISP serial programmer at port 
				   avrisp2,: use AVRISP2 (stk500v2) serial programmer at port 
				
				   The dev or host parameter for the programmer option need not be specified,
				   in which case it is expected to be defined as in an environment variable of
				   the same name in all caps (such as MIB510, EPRB, or AVRISP).
