ZIPPYby codename_B"installing mods shouldn't be this easy" What is it? It's a small java app written to be able to combine a zip file and a jar file easily with no external clients, just plugin in the variables and run the java application. How to use: Place in the same directory as the zip and the jar you want to combine. Run java -jar zippy.jar source.zip destination.jar It will then create a new destination.jar - without you having to unzip the zip and worry about combining the two or corrupting your jar. Great for installing SMP mods etc! Download Link: Here Supported Formats: .zip .jar UPDATE: 07/07/11 Zippy will now remove the META-INF folder when combining - the next update will cause this to only occur if the destination file is named "minecraft.jar" but for now, this is a quick workaround for easy installing of zombe Zippy now also has a GUI - no more command line stuff!
