avr-dude is commonly used with jtagice mkii (specially in Linux), so it could be useful to have a proper Makeburn in the official NutOS tree so that avr-dude-mkii (or whatever name) can be selected as a programmer in nutconf (Edit->Setttings->Samples)
possible Makeburn for avr-dude + jtagice mkii (adapted form Makeburn.avr-dude)
