Comment template in VS2010

Question

I have inherited an API which doesn't have proper comments, and I am working on changing that.

Anyone know if there is some sort of mechanism to add a default XML comments to all the members of a class or an assembly? (I remember seeing something like that on a webcast and I think he might have used PowerShell script to achieve that.)

This way I can avoid lots of repetitive steps, and have everything in place to go and start writing just the comments.

Anyone has any better suggestions?
