Log message:
Import tex-xskak-1.4 as print/tex-xskak.

Xskak, as its prime function, saves information about a chess
game for later use (e.g., to loop through a game to make an
animated board). The package also extends the input that the
parsing commands can handle and offers an interface to define
and switch between indefinite levels of styles.
