How to uninstall all cabal packages?

[Volker Wysk]

Hi!

I want to remove eveything which cabal has installed, and begin again with a clean installation. How is this accomplished? I've deleted ~/.cabal, but it still says that hsshellscript is already installed:

desktop ~ $ cabal install hsshellscript
Resolving dependencies...
All the requested packages are already installed:
hsshellscript-3.4.3
Use --reinstall if you want to reinstall anyway.

Bye
