[Haskell-cafe] Cabal - how do I remove a package?

[Paul Moore]

As it says in the subject, how do I remove a package that I installed
(with the --user flag) via cabal?

Come to that, how do I list the packages I've installed via cabal?
cabal list --installed includes all the GHC standard library (which I
didn't install) and it doesn't seem to support a --user flag to list
per-user installed packages.

FWIW, I'm on Windows 7.

Thanks,
Paul.
