[chbot] AVR external interrupt and Makefile example

[Richard Jones]

Thanks Charles,

Nice suggestion, very gratefully received as I was unaware of github.
Is there something similar for bazaar or should I learn git? I've not used
bazaar yet either, but it is on my todo list and I think more compatible
with my cvs/svn background.
I Like the straight forward makefile in bump and turn, readable by mortals
like myself!
So for the next step in avr Makefiles I suggest folks have a look at yours
rather than adapt my simplified one.

Cheers

Richard
