  * Tweak where the default config lives and where we keep the package list
  This should make it all "Just Work"tm. We no longer need a Makefile
  to do the installation. The point is, don't bother trying to use
  /etc/cabal-install/srve.list as the global list. That's hard to do
  because it involves installing that file, and we only want to do that
  for global installs, so it's even more complex. Instead we should just
  use cabal's facility to install data files. That way it ends up in
  /usr/local/share/cabal-install-x.y/
  or somewhere similar for a user install. But either way, cabal handles it.
  The per-user config sill overrides this one, so it's still possible to edit
  the list even if /usr/local/share/ is read-only. Also, we always use
  $HOME/.cabal-install/ for the per-user config and package cache.
  The one downside is that if an admin wants to use /etc/ and /var rather
  than /root/.cabal-install/ then this is a tad harder. But the point is
  at the moment it'll at least work for most people without fiddling,
  including windows users.
