A Builder script I created to build all OS releases together without a lot of clicking

Builder.cs

using UnityEngine;
using UnityEditor;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using Stopwatch = System.Diagnostics.Stopwatch;

public class Builder {

    	private static string[] levels = new string[] {"Assets/<Scene File.unity>"};
	private static string buildPath = Application.dataPath.Replace("Assets", "/")+"Builds/";
	// This is project specific
	// Change each key to the path/directory structure you prefer
	private static Dictionary<string, BuildTarget> buildTypes = new Dictionary<string, BuildTarget>() {
		{"Windows/<Windows 64bit Release.exe>", BuildTarget.StandaloneWindows64},
		{"Windows/<Windows 32bit Release.exe>", BuildTarget.StandaloneWindows},
		{"Mac/<OS X Universal Release.app>", BuildTarget.StandaloneOSXUniversal},
		{"Linux/<Linux Universal Release.x86>", BuildTarget.StandaloneLinuxUniversal}
	};

	[MenuItem("Tools/Build Project", false, 1)]
	private static void BuildProject() {
		Stopwatch timer = new Stopwatch();
		timer.Start();
		foreach (KeyValuePair<string, BuildTarget> entry in buildTypes) {
		if (File.Exists(buildPath + entry.Key)) {
				File.Delete(buildPath + entry.Key);
			}
			Debug.Log("Building " + entry.Key);
			BuildPipeline.BuildPlayer(levels,buildPath + entry.Key, entry.Value, BuildOptions.None);
		}
		timer.Stop();
		Debug.Log("Building took: "+(timer.ElapsedMilliseconds/1000)+"s");
	}
}
