Multiple independent projects per directory

This would have been an interesting exercise before about a month ago.
But SRC occupies this exact functional niche and has VC support.  By
what I see in my mailbox it's spreading like wildfire. I keep getting
this reaction: "Until I saw this I had no idea it was exactly what I
wanted."

The stack looks like this: Emacs VC -> SRC -> RCS.  There's a win from
having SRC as an intermediate layer that is part UI and part
architectural.  Its command set is good to have in circumstances where
you want the features but don't have Emacs handy, and it keeps the
complexity of the Emacs code really low.  You might find it
instructive to compare vc-rcs.el with vc-src.el.
