Thanks, I am now checking it.

But it seems not to work :-(

Consider this short file test.ads:

  package test is
    end test;

I run /usr/local/stow/gnat-gpl-2017-x86_64-linux-bin/bin/gnatpp -i3 test.ads

There is no output and the file is not changed, it's wrong alignment 
remains.

What is wrong?
