Examples of modificationReader task in CC.Net?

Question

I am trying to set up a build chain that propagates a modification history through the various build stages. My first thought was modificationWriter/modificationReader pairs, but I am having trouble getting the reader to read the results. Does anybody have any examples or tips?

I am using the latest CC.NET 1.4.4 SP1. Thanks!

Got it after some playing.

Note that you need a recent version of CC.NET, I think version 1.4.3 or newer. This is from 1.4.4 SP1.

I had first tried on 1.4.0 but the ModificationReader task doesn't exist in older versions.
