title: Finding missing nuget packages in local repository
body: <p>I have a local nuget repository (Nuget Server). I need to upload packages from Nuget.Org to my local repository for offline building.</p>
  <p>How can I list all packages missing for some solution? I need it to list all missing packages and thier depedecies (if it's missing too).</p>
  <p>Is there a way to do it with nuget command line, other tools, powershell script (any other way)?</p>
