bake constraints(for animation) inlatest version???

greetz, im a 2.49b user and so moving to 2.5x and above is quite chellenging due to their UI etc. in 2.49b there is an options in script window to ‘bake constraint’ and remove the IK without altering the armature’s animation.been searching for script window for ‘bake constraint’ in latest version but no luck so my question is how to do that in latest version of blender??:confused:
