## What it is
Cabal is the official build and packaging system for Haskell, comprising the Cabal library, the .cabal file format specification, and the cabal-install tool. It handles building Haskell projects, resolving dependencies from Hackage, and distributing packages in a portable way.

## Use cases
- build and package a Haskell library or application
- manage Haskell project dependencies from Hackage
- initialize a new Haskell project with cabal init
- resolve version constraints for Haskell packages
- install Haskell packages from Hackage
- define portable build metadata in .cabal files

## When to choose
- you are developing any Haskell project and need a standard build tool
- you want dependency resolution and package installation from Hackage
- you need a portable, spec-driven packaging format for Haskell libraries

## When to avoid
- you prefer Stack's curated snapshot workflows for reproducible builds
- you are not working with Haskell or GHC
- you need a general-purpose build system for non-Haskell languages

## Facets
- artifact type: cli-tool
- maturity: stable
- function: build-tool, package-manager, cli, developer-tools
- domain: developer-tools, programming-languages
- platform: windows, cli, cross-platform
