title: How to prevent installing documentation for gems automatically using gem v. 2.0
body: <p>Previously set up my system to suppress installing gem documentation with <code>--no-ri</code> and <code>--no-rdoc</code>.</p>
  
  <p>Ruby 2.0.0 and gem 2.0.0 seems to have removed the <code>--no-ri</code> flag (and functionality?).</p>
  
  <p>Even when specifying <code>--no-rdoc</code>, I still get <code>installing documentation</code>:</p>
  
  <pre><code>~/dev/ruby&gt; gem install bundler --no-rdoc
  Fetching: bundler-1.3.1.gem (100%)
  Successfully installed bundler-1.3.1
  Done installing documentation for bundler (0 sec).
  </code></pre>
  
  <p>How to see whether or not documentation is installed? If it is installed, how to suppress for all gem installs?</p>
