Minecraft Starter for hosting and playing different versions of Minecraft
How to use:
Copy Minecraft-Starter into the same directory like Minecraft.exe.
Start the program and save the current version of Minecraft under a different
name like minecraft_1.1.jar or minecraft_1.2.5.jar or minecraft_1.2.5_xray.jar etc.
You can do this by going to File-Save or hit the button Archive last minecraft version.

If another new version of minecraft is published, you can save it under its version
name and the next time you start Minecraft Starter you can choose it.
Maybe you want to use a modfile instead of the regular minecraft you can choose the 
version you want from the start menu if you saved the modfile under a different name.

Have fun! This program has been developed on the needs of my son Jonas.

If you do not have Python installed you can download the Minecraft-Starter.exe from
http://www.homoeopathie-online.com/Minecraft_Starter.exe
