The engine binaries alone are not enough — you must install a data root
first. Obtain the Steam "Arma: Cold War Assault Remastered Demo" (free)
and optionally the retail 2001 game from GOG:

    https://store.steampowered.com/app/4819000/
    https://www.gog.com/game/arma_cold_war_assault

Then populate the data root with the install helper shipped by this port:

    install-cwr-data --help

By default the helper installs into \$HOME/.local/share/CWR/base. To use a
different location, set \$CWR_DATA before launching:

    export CWR_DATA=/path/to/data-root
    cwr-ce

EOF
	exit 1
fi

exec PoseidonGame -C "${DATA_ROOT}" "$@"
