That's true, though I don't think I'd recommend it. The current
convention of <pkgname>.cabal is good and will work well with multiple
packages sharing one source tree.

My plan for the command line interface is that cabal
configure/build/install in a dir with multiple .cabal files will act
on all of them. Individual packages, or components within packages
will be selectable by name, e.g. "cabal configure" (configures all
packages) "cabal build foo" (builds just target foo).

I'm not quite sure how to handle name clashes, but I expect we can
work something out. For example, a package A containing exe A and B.
Does A refer to the package (components A and B) or just to the
component A?
