# bootstrap launcher — curl <shortener> | bash

# This file is intentionally tiny and stable: its only job is to clone the
# bootstrap repo (or update an existing clone) and hand off to setup.sh.
# All real logic lives in the repo so you can update it with `git pull`.
#
# Usage:
#   curl -fsSL <shortener> | bash
#   curl -fsSL <shortener> | bash -s -- --yes
#   curl -fsSL <shortener> | bash -s -- --only packages
