# Description:
#   A script to build Windows MSI packages for NuShell. Need wix 6.0 to be installed.
#   The script will download the specified NuShell release, extract it, and create an MSI package.
#   Can be run locally or in GitHub Actions.
# To run this script locally:
#   load-env { TARGET: 'x86_64-pc-windows-msvc' REF: '0.103.0' GITHUB_REPOSITORY: 'nushell/nushell' }
#   nu .github/workflows/release-msi.nu
