title: Updating local nuget package on post-build event
body: <p>I have my local nuget library repository separately both for my personal and work releted class libraries.</p>
  
  <p>I have created some of the nuget packages for the libraries which are no longer in development. I did this only for them because I do not know how to update them automatically as soon as my project builds.</p>
  
  <p>I have figured that all the work is being done by nuget command line with Visual Studio Command Prompt. So I can easily do the work I needed (of course I would know commands perfectly and I do not !)</p>
  
  <p>Basically I want the following tasks to execute on the post-build event of my project.</p>
  
  <p>On project build: </p>
  
  <ol>
  <li>copying project dll into a specific folder (lib folder of the nuget package)</li>
  <li>updating nuspec file for new file version (my project is increasing the file version on every build)</li>
  <li>creating new nupkg file with new file version</li>
  </ol>
  
  <p>Phil Haack shows some of this feature but it is still a prototype as far as I can tell. </p>
  
  <p>So my requirement is the above. Has anyone else accomplished this?</p>
