def render(template, data)

  # META! Assign instance variables to self using the hash passed in.
  data.each { |key, value| instance_variable_set "@#{key}", value }

  # Get the absolute template location relative to our template basepath.
  template_location = File.join(template_path, template)

  # Let Tilt do the rest. Also pass in `self` as that's the reference to
  # the object that holds our new, metaprogrammed `@instance_variables`.
