pub fn run(
root: &Path,
options: &Options,
game: &dyn GameTools,
target: Option<&TargetProfile>,
) -> Result<String, String>Expand description
Runs the command: the game plays the script and paints the frame, as
the display of target (the profile of Options::target) shows it,
which is written under root (if out is relative); returns what to
print.
