<#
.SYNOPSIS
    {{ app_display }} uninstaller (Windows).

.DESCRIPTION
    Generated by ariza from {{ app_name }}'s ariza.toml. Do not edit this
    file: edit ariza's resources/templates/uninstall-windows.ps1.j2 and
    re-run `ariza installers --app=<this repository>`.

    Removes exactly what install.ps1 created: the versions directory, the
    `current` junction, and the PATH entry it added. Anything
    {{ app_display }} itself wrote — your data, your configuration — is left
    alone, and this says where it is rather than deciding for you.

.EXAMPLE
    irm {{ raw_base }}/uninstall.ps1 | iex

$AppDisplay = '{{ app_display }}'
$AppExec    = '{{ app_exec }}'

$ArizaRoot   = Join-Path $env:LOCALAPPDATA $AppDisplay
$ArizaBinDir = Join-Path (Join-Path $ArizaRoot 'current') 'bin'
