Well, on a normal Linux distro a user should *never* have to call cabal (or
any of its cousins) directly, the distro's package manager should be the used
instead. On an e.g. RPM system, the .spec file would use Cabal to e.g.
(un-)register a package, because RPM has to know what is installed, which
other packages are prerequisites, how to cleanly uninstall, etc. IMHO Cabal
should not try to mirror a full-fledged package system, simply because on
every (non-Windows ;-) platform there are tons of native tools for this
purpose, and Cabal is not "in the driver's seat" when it comes to SW

Of course we are not the first project to face this kind of problem: Texinfo
offers a central contents page as well. To maintain this page, it comes with
a tool "install-info", which updates the index page after (de-)installation.
On RPM systems, the .spec file calls install-info after (de-)installation of
a package with info pages.

A "install-haddock" tool would be the solution IMHO.
