title: What does vendor mean in web file structure?
body: <p>Every now and then I see <strong>vendor</strong> being used in a directory structure on web apps.</p>
  
  <p>Like this:</p>
  
  <pre><code>&lt;script src="js/vendor/modernizr-2.6.2.min.js"&gt;&lt;/script&gt; 
  </code></pre>
  
  <p>What does this mean? Why do people use it?</p>
  
  <p>More importantly, should <em>I</em> use it? I make web apps using php and javascript.</p>
