Nano "Board Not Supported"

[Evolutionary Computation Laboratory]

The AVR-Nano distro is touted as running on, well, you now, the (328P) Nano. But if you compile it for the Nano, it comes up as "Board Not Supported". And indeed, it's not listed among the boards below.

Ah, I think you don't have it listed because you're assuming the board is changed to Uno after the bootloader is changed. It might be good to have an error generated to that effect...

Yes, as explained here: Arduino Uno and Nano.

I agree I could handle that better than "Board not supported". I'll add an error as you suggest - thanks!
