Strictly speaking, you are correct -- a bootloader is on the device
under test (DUT) side. Still, this facility, unlike any other, can be
donloaded in its entirety. It would take some time before we would be
able to 3D print a JTAG ICE tool ;-)

The current butterfly.c must be working with pretty lousy AVRBOOT
implementations. See for example how EEPROM bytes are programmed one
byte at a time. It's indicative of having no buffering in the
implementation...

By having an official AVRDUDE bootloader we can improve on both sides,
host and DUT.

What's wrong with GitHub...

I run avrasm2 via wine. AVRA is buggy, ask any AmForth user to tell
<http://amforth.sourceforge.net/>.

Thanks, Enoch.
