+1 I think it is sorely needed.

If we can come up with a really slick solution like Spark, then great. I am
also not against a half-baked solution that can later evolve into something
else.  For example, create an index README.md that links together all the
existing READMEs and run Pandoc on it.  Not ideal, but way better than what
we have.
