//! Package installation module for xbp
//!
//! This module provides functionality to install various packages using
//! predefined shell scripts. It supports executing installation scripts
//! for supported packages and provides debug output for troubleshooting.

/// Installs a package by name using the corresponding installation script
///
/// # Arguments
///
/// * `package_name` - The name of the package to install (e.g., "grafana")
/// * `debug` - Whether to enable debug output during installation
///
/// # Returns
///
/// * `Ok(())` if the installation was successful
/// * `Err(String)` if the package is not supported or installation failed
///
/// # Examples
///
/// ```
/// let result = install_package("grafana", true).await;
/// match result {
///     Ok(()) => println!("Installation successful"),
///     Err(e) => eprintln!("Installation failed: {}", e),
