MineTweaker is a mod which allows users and server owners to create scripts that modify, remove, and add recipes. It also has limited mod machinery support for BuildCraft, IndustrialCraft 2, GregTech, Forestry and MineFactory Reloaded.
This is a very useful tool for server owners as it allows you to effectively ban items by completing removing the users ability to craft them, by removing the recipe. Remove easy recipes and replace them with harder ones and even add recipes for items and add recipes for items that don't normally have recipes.
Important Note: The config file for MineTweaker is usually in the main config folder when shipped with mod packs, but for the mod to actually work you need to create a folder called minetweaker in the server's world folder, then put the minetweaker.cfg file in that folder e.g. goes in the minecraft/world/minetweaker folder not the minecraft/config/minetweaker folder. If you don't do this your script(s) will not work at all. If you are testing up over write the config file and run the command "/mt reload" to apply the changes to your server.
