  # The entrypoint for defining your web interface, such

  # This can be used in your application as:

  #     use DevWeb, :controller
  #     use DevWeb, :view

  # The definitions below will be executed for every view,
  # controller, etc, so keep them short and clean, focused
  # on imports, uses and aliases.

  # Do NOT define functions inside the quoted expressions
  # below. Instead, define any helper function in modules
  # and import those modules here.
