Simplest way to iterate over all GameObject childrens from a script at runtime

Question

In my Unity3D project I got a complex GameObject of a truck that his hierarchy looks like this.

+ Truck
   +FrontPivotPoint
      +LeftWheel
        Tire
        Rim
        Hindge
      +RightWheel
        Tire
        Rim
        Hindge
    +CenterPivotPoint
      +Body
        Arm
        Screw
        Pin  

Basically what's happening is I got a lot of complex parenting and I want to go trough every child and add to him a RigidBody. I think it should be something nested but I don't have something in mind. Any help would be appreciated!

Unity3d allows you to easily automate every routine. You may consider to add custom menu item.

public class MakeRigidBodies : EditorWindow
{
  [MenuItem ("Make rigid bodies %&r")]
  private static void Execute()
  {
    var selectedObject = UnityEditor.Selection.activeObject;
    if( selectedObject && selectedObject is GameObject )
    {
       // for all children of selectedObject
       {
         // add rigid body
       }
    }
  }
}
