/* Info:
 * Currently For Optifine / Iris shader packs,
 * could be expanded to support others should they exist?
 *
 * This class and enum are mostly here as placeholders for validating
 * that a shaderpack exists and is in the right format,
 * namely that they contain a folder named 'shaders'.
 *
 * In the technical sense it would be possible to parse files like `shaders/shaders.properties`
 * to get information like the available profiles but this is not all that useful without more knowledge of the
 * shader mod used to be able to change settings.
