What I need is somebody who can make a small program (windows) that can copy 2 .class files into minecraft.jar and delete the METADATA folder. All of this automatically. It can be any language and it has to be a 1 click program.
-The minecraft.jar is NOT in the usual appdata folder
-The program will be in the root folder of the "thing"
-From the root folder, minecraft.jar is found via [ROOTFOLDER]\data\.minecraft\bin (or %CD%\data\.minecraft\bin)
-I'll also need the source code and it needs to be a simple command that you can copy/paste just with a different class name and it will copy (it's for the custom map makers).
