title: What is gem install bundler?
body: <p>I know i can read it from <a href="http://bundler.io" rel="nofollow">http://bundler.io</a>, but i have some doubts in my mind. </p>
  
  <ol>
  <li>Is it like <code>npm for NodeJs</code> and <code>Maven for Java/J2EE</code>.</li>
  <li>The first command i executed is <code>gem install bundler</code>. What is gem here and What is bundler, can some one enlighten me in terms of <strong>NodeJs or Maven</strong>.</li>
  <li>Where these getting installed?. I don't specify <code>-g</code> like i do in
  NodeJs for globally.</li>
  </ol>
