Well, that would be a bit of an inconvenience to everybody that wants to
use the Cabal file.  I would prefer we just kept it in the repository

I understand that you see Cabal as just a packaging system among others,
and I would like to propose a slight nuance to add to your view.

Cabal files exist to make packaging darcs easier: cabal-install,
MacPorts, Debian, RedHat, ArchLinux, Gentoo, Cygwin all could benefit
from having a single reference point for our Haskell package dependency
information.  Providing an official Cabal file makes it easier for a
diverse group of packagers to install darcs and indirectly makes it
easier for people to install darcs, which is a very good thing for the

In other words, the nuance consists is separating the discussion on the
merits of Cabal from that of cabal-install.  Hackage/cabal-install can
be seen as a packaging system among others (Gentoo, etc), and I can
understand your resistance to giving it any special treatement.  Cabal
itself on the other hand, should become part of darcs, because it allows
us to help lots of different people package darcs for very little cost.

As a separate issue, I personally think we should also make some effort
to ensure that "cabal install darcs" works... and the reason for doing
this is that it validates our cabal file and gives packagers confidence.

Ok.  I hope my next patch is more reasonable.
