title: Restoring node-modules and bower_components based on script contents
body: <p>How do I restore node-modules and bower_components?</p>
  <p>I want to source control files which are <em>actually</em> part of my application and not the dependencies.
  I want to restore those dependencies after I clone a fresh copy of my project.
  Something like the inverse of <em>bower wiredep</em></p>
