How to allow an author to moderate comments??

Could anybody point me in the right direction to allow an author to moderate comments using wordpress 2.5?? I know I can just make him an editor, but I don’t want them to be able to edit pages and all that good stuff.. Just want to keep it simple.. Perhaps there is a plugin out there that I am not finding for this, or some code I could change somewhere to allow this..

Thanks to all reply’s ahead of time..
