# Last Updated : 12/11/2025
# ==========================================================
# Description:
# This script installs and configures ProxMenux, a menu-driven
# toolkit for managing and optimizing Proxmox VE servers.
#
# - Ensures the script is run with root privileges.
# - Displays an installation confirmation prompt.
# - Installs required dependencies:
#     • whiptail (interactive terminal menus)
#     • curl (downloads and connectivity checks)
#     • jq (JSON parsing)
#     • Python 3 + venv (for translation support)
# - Creates the ProxMenux base directories and configuration files:
#     • $BASE_DIR/config.json
#     • $BASE_DIR/cache.json
# - Copies local project files into the target paths (offline mode by default):
#     • scripts/*     → $BASE_DIR/scripts/
#     • utils.sh      → $BASE_DIR/scripts/utils.sh
#     • menu          → $INSTALL_DIR/menu (main launcher)
#     • install_proxmenux.sh → $BASE_DIR/install_proxmenux.sh
# - Sets correct permissions for all executables.
# - Displays the final instruction on how to start ProxMenux ("menu").
#
# Notes:
# - This installer supports both offline and online setups.
# - ProxMenux Monitor can be installed later as an optional module
#   to provide real-time system monitoring and a web dashboard.
