Minecraft version changer tool

I have been using this program for a while, and it is at
http://digiex.net/minecraft/mcvtool/
It allows you to switch quickly between minecraft versions

If you want, I will post a tutorial on using this program to switch quickly between a modded and unmodded minecraft(please tell me if you want this tutorial)

Disclaimer: I did not make this program.

For people who are wondering exactly how to use it, here's a(hopefully very helpful) tutorial... with pictures DD.

1. Go to http://digiex.net/minecraft/mcvtool/ and download it for your operating system.




2. Run it, and when it opens click options




3. Click Jar downloader




4. For some reason, the download manager opens behind everything; minimize(DONT CLOSE) mclauncher and everything else you might have open, and you should see the download manager. Click the dropdown menu and select what minecraft.jar you want to download, then click add download.

You can download:
-Every single version released from Minecraft alpha 1.0.14 through Minecraft Beta 1.9 pre-release 4
-Survival test 0.30
-Minecraft classic 0.30
-Minecraft Demo by PcGamer
-If you click latest beta, it will update regular minecraft to the latest version




5. Close the jar downloader and go back to mclauncher. Click the dropdown menu under your username and select the .jar you want to use, and click login. Note: If you don't see the jar you just downloaded, close and reopen mclauncher




6. Enjoy...
