title: How can I run rspec inside rspec-mode?
body: <p>I have a directory with files like this</p>
  
  <pre><code>.
  ├── example.rb
  └── example_spec.rb
  </code></pre>
  
  <p>And my <code>init.el</code> :</p>
  
  <pre class="lang-lisp prettyprint-override"><code>(require 'rspec-mode)
  (setq-default rspec-use-rvm t)
  
  (require 'rvm)
  (rvm-use-default)
  </code></pre>
  
  <p>When I try to run any of the verify functions inside the <code>example_spec.rb</code> will result the error :</p>
  
  <blockquote>
    <p>rspec-project-root: Could not determine the project root.</p>
  </blockquote>
  
  <p>How do I make <code>rspec-mode</code> able to <em>determine the project root</em> and run rspec ?</p>
