+// Package bose-soundtouch provides a comprehensive Go library and CLI tool for controlling Bose SoundTouch devices.
+//
+// This library implements the complete Bose SoundTouch Web API, enabling programmatic control
+// of SoundTouch speakers including playback control, volume management, source selection,
+// multiroom zone management, and real-time event monitoring via WebSocket connections.
+//
+// # Quick Start
+//
+// Install the library:
+//
+//	go get github.com/gesellix/bose-soundtouch
+//
+// Basic usage example:
+//
+//	package main
+//
+//	import (
+//		"fmt"
+//		"log"
+//
+//		"github.com/gesellix/bose-soundtouch/pkg/client"
+//	)
+//
+//	func main() {
+//		// Create a client for your SoundTouch device
+//		config := &client.Config{
+//			Host: "192.168.1.100",
+//			Port: 8090,
+//		}
+//		client := client.NewClient(config)

+//		// Get device information
+//		info, err := client.GetInfo()
+//		if err != nil {
+//			log.Fatal(err)
+//		}
+//		fmt.Printf("Device: %s\n", info.Name)
+//
+//		// Control playback
+//		err = client.Play()
+//		if err != nil {

+//		}
+//
+//		// Set volume
+//		err = client.SetVolume(50)
+//		if err != nil {
+//			log.Fatal(err)
+//		}
+//	}
+//
+// # Device Discovery
+//
+// Automatically discover SoundTouch devices on your network:

+//
+//	// Subscribe to device events
+//	events, err := client.SubscribeToEvents(ctx)
+//	if err != nil {

+//	zone := &models.Zone{
+//		Master: "192.168.1.100",
+//		Members: []models.ZoneMember{

+//		},
+//	}
+//	err = client.SetZone(zone)
+//
+// # CLI Tool
+//
+// The package includes a comprehensive CLI tool for device control:
