Are they really necessary for just one block?
Becouse it's use a Display-Gui, it's more then only a Block...:
Item.java is acy.class (used by the Mystic-Stone)
TileEntity.java is bq.class (used for mapping)
EntityPlayerSP.java is di.class (used by the Gui)
CraftingManager.java is sl.class (used by the Recipes)
EntityPlayer.java is vi.class (used also by the Gui)
Block.java is yy.class (used by the Recycler-Block)
Perhaps there is a smarter way to script this, I don't know (my basic programming language is PHP for Web and a little bit C++).
I thought the normal Version for those, who don't want to download 100 other programms to only run one Mod and the Modloader-compatible Version for all the other (including myself).
