This is made for the daring.
What it does:
This is what it pretty much says on the tin: Self Delete Linux.
If you enter in a false command in terminal, all of your files will be deleted. All gone. Zilch.
It WILL warn you if you have it installed when you open Terminal.
So don't enter gibberish or a wrong command in Terminal when you install this.
