title: Find linked NPM package
body: <p>I have a bizarre issue. </p>
  
  <p>I have written a package for Node for local use, and used NPM link to make it available for command line use globally.</p>
  
  <p>Now I need to change the package, I can not find it on my drive but the package is still linked through NPM and usable. </p>
  
  <p>Can NPM give me the path for linked modules?</p>
