title: Yeoman generator.fs.copyTpl - How to output literal '<%'
body: <p>I'm working on my first Yeoman generator and need to output some literal ejs tags for later processing. I'm able to achieve this by escaping the tag with an additional '%' per the ejs docs (<a href="http://ejs.co/" rel="noreferrer">http://ejs.co/</a>). For example:</p>
  
  <pre><code>&lt;%% myModule %&gt;
  </code></pre>
  
  <p>I can process this without issue using the deprecated <em>generator.template()</em>, and the destination file contains the expected output:</p>
  
  <pre><code>&lt;% myModule %&gt;
  </code></pre>
  
  <p>However, when I attempt to use <em>generator.fs.copyTpl()</em> to process the same file, I get the following synthax error: </p>
  
  <pre><code>SyntaxError: Unexpected token %
  </code></pre>
  
  <p>Do I need to explicitly pass an escape character in the ejs options object? Is there something else I'm missing? </p>
  
  <p>Any ideas? Thank you! </p>
