  <p>Hello World</p>
content.html
  <p>Blah blah blah</p>
  {% include "foo.html" %}
  <p>Yada yada yada</p>It would output the following:

  <p>Yada yada yada</p>
Passing values

  <p>Blah blah blah</p>
  {% include "foo.html" name = "Dean" %}
  <p>Yada yada yada</p>It would output the following:
  <p>Blah blah blah</p>
