This is a release-candidate for 0.6, which will be in GHC 6.4. http://www.haskell.org/cabal/download.html The Haskell Cabal The Common Architecture for Building Applications and Libraries. http://www.haskell.org/cabal IMPORTANT INFORMATION: See both the README file and the changelog for important interface changes. DOWNLOAD: The Haskell Cabal has reached pre-release stage. The community should use this release to evaluate the interfaces and explore the concepts of these tools. Download the Cabal here (source and debian versions available): http://www.haskell.org/cabal/download.html BUGS: Please report bugs and wish-list items to libraries@haskell.org and Isaac Jones: ijones@syntaxpolice.org. ABOUT: The Haskell Cabal is meant to be a part of a larger infrastructure for distributing, organizing, and cataloging Haskell Libraries and Tools. It is an effort to provide a framework for developers to more effectively contribute their software to the Haskell community. Specifically, the Cabal describes what a Haskell package is, how these packages interact with the language, and what Haskell implementations must to do to support packages. The Cabal also specifies some infrastructure (code) that makes it easy for tool authors to build and distribute conforming packages. The Cabal is only one contribution to the larger goal. In particular, the Cabal says nothing about more global issues such as how authors decide where in the module name space their library should live; how users can find a package they want; how orphan packages find new owners; and so on. NOTES: You cannot currently execute the setup scripts with "./Setup.lhs" since Cabal Hugs support isn't ready-for-prime-time. You can compile it with ghc thusly: "ghc -package Cabal Setup.lhs -o setup" and then use the "setup" executable after that. This release is meant to provide the community with concrete information about how the interfaces are shaping up. This release does NOT fix the interfaces, we can't promise not to break anything that relies on these interfaces. We hope that Haskell authors will try to package their software using these tools, and let us know where they fall short. MORE INFORMATION: Please see the web site for the source code, interfaces, and especially the proposal, which will serve as documentation for this release: http://www.haskell.org/cabal/
