Or we could create a scm suffix and not have to parse ebuilds to get
that info.  As an added bonus live ebuilds are instantly identifiable
and can use proper versions numbers instead of 9999.

Just as easy with -scm.

His problem is updating the packages in a specific order.  I don't
remember sets preserving merge order, but then again I wasn't looking.

I could have sworn subversion.eclass already did this but now I can't
find the code.  I might have seen it in an overlay or on the forums.
