title: Format of EJS and JST template files in rails-backbone gem
body: <p>I am using the rails-backbone gem ( <a href="https://github.com/codebrew/backbone-rails" rel="nofollow noreferrer">https://github.com/codebrew/backbone-rails</a>). For rendering HTML, it uses some kind of javascript templates, whose name I cannot tell even after a few hours of search.</p>
  
  <p>For example, it generates such a file for the view template:</p>
  
  <pre><code># company.jst.ejs
  &lt;td&gt;&lt;%= name %&gt;&lt;/td&gt;
  &lt;td&gt;&lt;%= tid %&gt;&lt;/td&gt;
  
  &lt;td&gt;&lt;a href="#/&lt;%= _id %&gt;"&gt;Show&lt;/td&gt;
  &lt;td&gt;&lt;a href="#/&lt;%= _id %&gt;/edit"&gt;Edit&lt;/td&gt;
  &lt;td&gt;&lt;a href="#/&lt;%= _id %&gt;/destroy" class="destroy"&gt;Destroy&lt;/a&gt;&lt;/td&gt;
  </code></pre>
  
  <p>My questions are: what is .jst format? And in Rails 3.1, what library processes it? Same question for the .ejs extension. And what's the name of this template engine? Underscore? </p>
