Script for deleting Hidden Layers which are not used in any Layer Comp?

Hello.

I've turend the web upside down searching for a script that would do the following:

1. Search through all the layer comps in the document
2. Check which layers are hidden on all Layer Comps
3. Remove/mark with color the layers found.

If anybody can provide a script that would do such a thing - it would be highly appreciated.

Regards,

Fade.
