### Create a Basic Compojure Web Application

Source: https://github.com/weavejester/compojure/blob/master/README.md

This Clojure code snippet demonstrates how to create a simple Ring handler using Compojure. It defines two routes: a GET request for the root path ('/') returning 'Hello World', and a fallback route for 'Page not found'.

```clojure
(ns hello-world.core
  (:require [compojure.core :refer :all]
            [compojure.route :as route]))

(defroutes app
  (GET "/" [] "<h1>Hello World</h1>")
  (route/not-found "<h1>Page not found</h1>"))
```
