Stackage
Stackage is an infrastructure to create stable builds of complete package sets (henceforth we call them “snapshots”) and provide them as sets of packages to users. Think “stable Hackage”.
To use Stackage for more reliable builds, visit stackage.org. You can also skip to the getting started instructions.
To add a package to Stackage, [1].
One of the easiest ways to get started with Stackage is to download a cabal.config file to your package directory and rebuild.
