.SYNOPSIS
Script to bootstrap a Haskell environment
.DESCRIPTION
This is the windows GHCup installer, installing:
* ghcup - The Haskell toolchain installer"
* ghc - The Glasgow Haskell Compiler"
* msys2 - Unix-style toolchain needed for dependencies and tools
* cabal - The Cabal build tool for managing Haskell software"
* stack - (optional) A cross-platform program for developing Haskell projects"
* hls - (optional) A language server for developers to integrate with their editor/IDE"
