title: Can jinja2 replace values in a properties file?
body: <p>Say you have a yaml like this:</p>
  <pre><code>foo: {{foo}}
  bar: {{bar}}
  </code></pre>
  <p>where foo and bar are variables past in as runtime arguments.</p>
  <p>Is jinja2 something that can replace these or should I be looking elsewhere?</p>
