title: Installing "global" npm dependencies via package.json
body: <p>I have a few "global" dependencies (jshint, csslint, buster, etc..) that I'd like to have automatically installed and executable via the command line when my package is installed via <code>npm install</code>.  Is this possible?</p>
  
  <p>Currently, I'm doing the following manually:</p>
  
  <ol>
  <li><code>npm install -g &lt;package_name&gt;</code></li>
  <li>from within my project: <code>npm link &lt;package_name&gt;</code> </li>
  </ol>
  
  <p>Update:
  Just came across <a href="https://github.com/isaacs/npm/issues/2949">this feature request</a> for npm.  It seems like the <code>scripts</code> config within package.json is the way to go?</p>
  
  <p>Update Again:
  Or, after reading the <a href="https://npmjs.org/doc/scripts.html">npm docs</a>, maybe I'm supposed to use a <a href="http://code.google.com/p/gyp/wiki/GypLanguageSpecification">.gyp file</a>?  I'm confused.</p>
