Robert,

It doesn't really matter, the changas for a particular
device are small and I did not found anything relevant
for the amforth prompt (at least).

There are a lot of inc files there which look basically all the
same:

------
....
; ***** BOOT_LOAD ********************
; SPMCSR - Store Program Memory Control Register
.equ	SPMEN	= 0	; Store Program Memory Enable
.equ	PGERS	= 1	; Page Erase
.equ	PGWRT	= 2	; Page Write
....

Hey, cool. Looks like ant is simpler in use than make
Nobody should say anything against java ;=))

works fine. If you look at the avr-buid.xml file, you will see
a <macrodef name="avrdude"> which has all the settings, including
some macros from programmer.properties and the build.xml in
your application directory. Way to complicate, IMHO. If anyone
has a better idea, let me know. CMake would be an option.

IMHO that ISP ardiuno should speak some standard protocol
like avr109 or avr910. But I've never tested them..

avrdude is a classic unix tool: many command line options
and works for smart people only ;=). But it has a verbose
mode which tells long stories..
