    >> Regarding the file "LEGGIMI", it has ALL wrong accented characters!

Someone, please fix it.  I committed what Marco sent me, although it's
certainly possible that it got corrupted somewhere along the line.

There is no file named "LEGGIMI".  It is a link in the top-level index.html.
The two files are
Master/readme-txt.dir/README.IT
Master/readme-html.dir/readme.it.html
