Cabal has been introduced to simplify packaging of Haskell software and modules. It was added to the Glasgow Haskell Compiler version 6.4 as default package manager, along GHC's internal manager ghc-pkg. The actual binary cabal and the library Cabal are developed in different packages.
Throughout its development it has gained additional features, such as sandboxes, which allow to escape the so-called Cabal hell (see below).
Cabal packages provide a standard set of metadata and build process; thus, it is possible to develop tools to upload Cabal packages to the CPAN-like community repository of software, Hackage, or even allow for automated downloading, compilation, and installation of desired packages from Hackage.
Cabal previously used a global package repository by default, version conflicts in dependencies could lead to Cabal hell, a state where certain packages couldn't get installed without re-installing already existing ones and therefore breaking the other packages.
In 2014, a more stable (but less bleeding edge) variant of Hackage called Stackage was created.  In 2015, it was extended with Haskell LTS and the tool stack, which doesn't share its problems.

Package management with cabal is the single worst aspect of using Haskell. Asked if improvements to package management would make a difference to their future choice of Haskell for a project, 38% said it would be "crucial" and a further 29% said it would be "important". Comments connected cabal with words like hell, pain, awful, sucks, frustrating, and hideous. Only this topic showed such grave dissatisfaction.
