Fair enough. It'd probably be useful to hook something in to use the
output of this class to produce a tree of just the sources that went
into a given image or sdk, to go alongside the new manifests. I think
this is good to go in though, I'll submit a second patch in the next
day or two to enhance it to cover more, unless someone disagrees with
that approach.
