title: Download nuget.exe using Powershell
body: <p>Can someone provide an example powershell script to bootstrap (aka download) NuGet.exe for a fresh system that only has the .NET 4.5 SDK installed?</p>
  
  <p>I would like to use psake to automate my entire build process and would prefer to not upload NuGet.exe into my VCS repository.</p>
