hi. nice script, looks exactly like the one written by a guy named kevin mannes. like, you know, 100% the same. i also wrote a similar script, see here http://www.highend3d.com/f/4879.html . what i find interesting is the fact that your script description is almost exactly the same as what i posted when i released my first version, the only difference is your e-mail address instead of mine.
weird, isn't it?
The tool you never knew you needed! This plugin will save you a ton of time by deleting Control Curves, baking (or ignoring!) Animations on Joints and Meshes, importing references and clearing name...
