# decomp.wtf installer for Windows (PowerShell).
#
#   irm https://decomp.wtf/install.ps1 | iex
#
# What it does, and nothing else:
#   1. installs uv, Astral's Python tool manager, if you don't have it
#   2. installs decomp.wtf (open source, MIT) with uv, in its own environment
#   3. downloads the N64 compilers that have Windows builds and the m2c draft decompiler (pinned, checksum-verified)
#   4. adds decomp.wtf to the Start menu and your desktop, and opens it
#
# Your projects go to %USERPROFILE%\Decomp. Nothing is sent to decomp.wtf.
# Uninstall: uv tool uninstall decompnet
