Change window name in custom editor

How do I change the name of my window in a custom editor script? The one I made is too large for the tab.

using UnityEngine;
using UnityEditor;

public class BreakableObjectSetupTool : EditorWindow {

	[MenuItem("Window/GDG Breakable Object Setup Tool")]
	public static void ShowWindow ()
		EditorWindow.GetWindow (typeof(BreakableObjectSetupTool));
	void OnGUI ()
		GUILayout.Label ("GDG Breakable Object Setup Tool", EditorStyles.boldLabel);

The GetWindow method is overloaded: Unity - Scripting API: EditorWindow.GetWindow

The last two should let you set the title.
