Hi,

Try to read, run and inspect the examples provided in the distribution
in /ecj/ec/app/. The parameter files are sort of the starting point.
Have a look at:
/parity/adf.params -- two ADFs that don't call one another
/twobox/adf.params -- only one ADF
/lawnmower/adf.params -- first (number 0) ADF has no arguments, the
other ADF can call the first

As far as I know there are no separate tutorials for ADFs, but going
through the above examples will help to understand how the ADFs are
approached in ECJ.
