// This example demonstrates how to serve static files from your filesystem.

// Boot the server:
//
// $ go run main.go
//
// Client requests:
//
// $ curl http://localhost:3333/files/
// <pre>
// <a href="notes.txt">notes.txt</a>
// </pre>
//
// $ curl http://localhost:3333/files/notes.txt
// Notessszzz
