# Odysseus — macOS installer (the downloadable "executable").
#
# Run it from Terminal:
#   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/LuisArmando-TestCoder/Odysseus/main/installer/bootstrap/install-macos.sh)"
# or download it and run:  bash install-macos.sh
#
# It:
#   1. installs the Xcode Command Line Tools (git) if missing, and waits for them
#   2. ensures Python 3.11+ (Homebrew python@3.12 if missing)
#   3. clones Odysseus into ~/odysseus (override with ODYSSEUS_HOME=/path)
#   4. runs the installer: credentials, environment, hourly auto-update from
#      the main branch, shortcuts, optional start-at-login, first launch
#
# Safe to re-run: an existing install is updated and repaired in place.
# Extra arguments go to installer/install.py (e.g. --non-interactive).
#
# Everything is inside main() so a partially downloaded script never runs.
