title: How to interpret file content as template string?
body: <p>I was wondering if there was a way to use the content read from a file as a template string? </p>
  
  <p>Ex: my file hello_world.txt :</p>
  
  <pre><code>hello world from ${name}
  </code></pre>
  
  <p>And then something like (with nodejs) :</p>
  
  <pre><code>var name = 'Jérémie';
  var fileContent = fs.readFileSync('./hello_world.txt');
  debug(fileContent); // Hello word from Jérémie
  </code></pre>
  
  <p>It seems possible, using the eval() function, but I don't really like this solution.</p>
  
  <p>Thanks</p>
