  Description     : Manage sandboxed Haskell build environments

cabal-dev is a tool for managing development builds of Haskell projects.
It supports maintaining sandboxed cabal-install repositories, and
sandboxed ghc package databases.

For most packages, just use cabal-dev instead of cabal, and you will get
a sandboxed build that will not install anything (even automatically
installed dependencies) into the user or global ghc package databases.
You can also add local sources for patched or unreleased libraries.
