Import tex-polyglossia{,-doc} 1.40.1. packaged by Christoph Badura, updated
by me.

This package provides a complete Babel replacement for users of
LuaLaTeX and XeLaTeX; it relies on the fontspec package,
version 2.0 at least. This is the first release that supports
use with LuaLaTeX; it should be considered "transitional" in
that role.
