+echo This script will download and install an optional library for enhanced Direct3D 12 support.
+echo The library will also be installed in the export templates folder, so they can be
+echo copied on export when a project is configured to use Direct3D 12.
+echo.
+echo This library is not as useful on Windows 11, but installing it will still benefit
+echo players on Windows 10 for projects you export from this PC.

+echo After updating Godot to a newer version, remember to run the Direct3D 12
+echo setup script that comes with it to install the Agility SDK[0m
+echo corresponding to the new Godot version. Each Godot version stores
+echo Direct3D 12 libraries in a version-specific folder to be copied when exporting.
