Hello, I appreciate ongoing work with cabal-install. I've tried the latest darcs version on a clean fresh ghc, and it worked fine. I wonder however, if there is any support (planned) for removing outdated packages. For example, when updating bytestring, I ended up with both xhtml-3000.0.2.1 and xhtml-3000.0.2.2 installed. Is there a something like a receipt, listing the files belonging to the installation of a package ? If there were such a thing (like copy --verbose, but machine readable), uninstalling a list of outdated packages would at least be possible. I wouldn't want cabal to remove outdated packages automatically, but some support for listing and removing them seems quite important to me. Oh, and it would be nice if config fields like 'global-prefix' are mentioned in the README. In the long term, in which way should cabal-install interact with package management tools like macports ? Is it supposed to be a replacement, an alternative or a complement ? I thought about writing something similar as cabal-rpm for macports, but it seems better to have cabal-install handle dependency resolution and installation. Injecting a package into the pm's database after installing is imho the nicest solution. Does this make sense ? Thanks, Benedikt
