#   curl -fsSL https://raw.githubusercontent.com/oxpoe/Gamemax-linux-apps/main/install.sh | bash
#
# Opsi:
#   --uninstall      lepaskan pemasangan (layanan, aplikasi, config, ikon, entri menu)
#   --no-service     pasang aplikasi saja, jangan aktifkan layanan/autostart
#   --version vX.Y.Z pasang versi rilis tertentu (default: rilis terbaru)
#   --remove-data    saat --uninstall: hapus juga ~/.config/gamemax-report
#
# UdeV: aturan izin device dipasang dengan sudo. Kalau skrip dijalankan lewat pipa
# (curl | bash) dan sudo butuh kata sandi, perintahnya dicetak untuk dijalankan manual.
