Yes, I started working with GRASS Python scripting library. I'm following
the link  you suggested, I'm also looking at other existing GRASS
scripts [1,2] and moreover, Roberto gave me one of his scripts as an
example. I have just committed the first version of the python script I'm
working on, it works and I'm quite satisfied ;-)
Tomorrow I want to elaborate the schema of the algorithm and at the same
time, I have to keep testing the procedure. As I wrote in the bash file,
shadows detection seems to be strongly land cover dependent therefore I
think it is necessary to test the procedure using several images sensed in
different seasons, latitude, etc.
Anyway, I'll commit some results tomorrow so as to show you something more
