Automagically Loads Minecraft Mod

gistfile1.txt

This is a mac specific script to load a mod into minecraft. In the terminal, run:

./mc_modloader.sh ModName.zip.

It will make a backup of your current minecraft jar, and attempt to merge the mod into it.

mc_modloader.sh

#!/bin/bash

# This will either take the provided mod, or prompt the user with a dialog.
