#!/bin/bash
# install-backend.sh
# This script installs the Arma Reforger Server Monitor backend on Linux.
# It performs the following steps:
# 1. Checks for prerequisites (like the .NET 6.0 Runtime).
# 2. Prompts the user for an installation directory and a master log directory (with examples).
# 3. Downloads the release package from GitHub.
# 4. Extracts the package into the chosen installation directory.
# 5. Prompts the user whether to create and enable a systemd service.
#    - If yes, it creates a systemd service file, reloads systemd, enables, and starts the service.
#    - If no, it reminds the user how to run the application manually.
#
# Verbose messages are printed for debugging and guidance.
