/* Info:
 * Currently For Optifine / Iris shader packs, 
 * could be expanded to support others should they exsist?
 *
 * This class and enum are mostly here as placeholders for validating 
 * that a shaderpack exsists 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 availble profiles but this is not all that usefull without more knoledge of the 
 * shader mod used to be able to change settings
