  -You might decide to move part of this application into a library. The `clj` tool uses local coordinates to support projects that exist only on your local disk. Let's extract the clj-time parts of this application out into a library in a parallel directory hello-time. The final structure will look something like this:

  Update the application at hello-world/src/hello.clj to use our library instead:
  
  [source,clojure]

negative.code:         └── hello.clj

  Under time-lib, use a copy of the deps.edn file you already have, and create a file `src/hello_time.clj`:
