The intention is to extend it to help developers working with multi-package systems. My claim is that all that requires is improvements in the tools, not a change in the notion of a package as the unit of distribution and dependency. > For my application, I suppose I could use autoconf/automake to develop > the software, install the executables, build a Cabal package > description, and then use it with Cabal to make the library available > as a package. Is this usage more inline with your intentions? We'd like to kill off autoconf as much as possible. :-) So we hope that developers will work directly with Cabal rather than generating Cabal packages from other systems. As I said before, my personal example is Gtk2Hs which is a relatively complex multi-package system. Currently it is impossible to package it with Cabal but we're getting closer. Gtk2Hs currently uses autoconf/automake and I can build everything with: ./configure make and I can rebuild everything with just make. And if there's nothing to do it takes a fraction of a second to work this out. I'd like to get to that stage with cabal. I'd like to say: cabal configure cabal build Or maybe just cabal build to get default configure parameters. And if I run cabal sdist I'd expect it to generate twelve .tar.gz packages that I can upload to hackage. With that kind of infrastructure there's lots of fun stuff we could do, like continuous build and test: cabal build --continuous & To get there of course we'll need lots of help from lots of people. I'd like to encourage people to get involved. Duncan
