Atkins and Carbs....?

So last night my friend and me got into a dispute about the Atkins Diet, they were trying to tell me that you indeed CAN eat carbohydrates on this diet, just in a restricted amount?? I have never heard of this i thought Atkins was all about NO CARBS! I looked online and found one website to say that now there is a new form of Atkins to let you eat some carbs, but i would really like to know if the true original Atkins diet follows a no carb diet....thanks to all that answer.
