+/* 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
