Scripting ragdoll creation

I'm looking for an automated way to add ragdoll to all my current and future characters. Is there way to create a script look for predefined names of the limbs in the models and build the ragdoll from that. I plan on having all the character following the same naming convetion for each limb so i should be able to select a game object an run the add ragdoll script and have it look through the object for the correctly named limbs and add the physics objects.

Thanks again in advance.
